CHAPTER 1: Touch Screen Storage, Packing and Unpacking

1.1 Storing the Touch Screen Ideal storage environment is between temperature of 20oC ~ 25oC with humidity less than 65%RH. For long term storage, goods must be kept in original carton packaging or be kept in its inner box and with the inner box covered with plastic bag. Take careful note of the following icons printed on the cartons.

Fig. 1 Carton Instructions

Follow the instructions as represented by the icons printed on the cartons - “Maximum 4 pcs. per stack pile” - “Keep Dry” - “This Side Up” - “Fragile”: handle with care.

There is a double carton, which is supported by 8 numbers of corner shock absorbers inside the external carton. The inner box is then packed into and protected by the smaller carton.

During long-term storage of touch screens packed inside external cartons, it is advisable to stack them up to 4 cartons.



1.2 Unpacking the Carton with Inner Box AMT provides three types of inner box: Plank type Block type Slot type

We use different types of inner box for packing different sizes of touch screens. Before starting the unpacking process, you are required to wear gloves to prevent fingerprints or stains occurring on the touch screens.

1.2.1 PPllaannkk TTyyppee IInnnneerr BBoox Plank type inner box is commonly used for large touch screens with diagonal size larger than 12.1”. Please follow the photos shown below on the proper procedures of unpacking a plank-type inner box. Always wear gloves when handling touch screens.

Fig. 14 Remove with care by the rim of the glass

1.3 Stacking the Inner Box

We suggest maximum 5 boxes per stack pile and must not compromise on the stability of the boxes at the top of the pile. For the Plank type and Block type inner box, we are to stack the boxes with the AMT logo facing upwards. However when we are stacking the Slot type inner box, it must be stack horizontally with AMT logo on the sides.



1.4 EPE Slot Type

The EPE type packages are design with slots to hold the touch screens vertically inside the box. This is the packaging design for large size touch screens and this design reduces environment impact and optimizes transportation cost management. There is also minimal use of non-dissolvable materials to help in recycling. The package mainly consists of EPE material which is suitable for use in clean room production therefore saving time and increases productivity. Always wear gloves when handling touch screens. Below are instructions for removal of touch screen from box.

CHAPTER 2: HOW TO HANDLE TOUCH SCREEN

After open the inner box of the touch screen, handle the touch screen properly, if the touch screen is large in size, we will suggest using two hands to take out the touch screen from the inner box. See the above three pictures, Fig. 6, Fig. 10 and Fig. 14

NNoonn--PPrrooppeerr WWaayyss ttoo hhaannddllee tthhee ttoouucchh ssccrreeeenn 1. For proper handling of touch screens, wear gloves at all times to prevent cuts to

yourself as the edges of the touch screen may be sharp. 2. Do not pull or crease the tail of the touch screen. See Fig. 15 and Fig. 16.

Fig. 15: Do not pull the tail

Fig 16: Do not crease the tail

3. Do not place any objects on top of the Touch Screen. 4. Place touch screen on flat clean empty surface. 5. Ensure the touch screen does not come in collision with any heavy object. See Fig. 17,

The touch screen surface hardness is only 3H.



Fig. 17 No collisions with heavy object

6. Do not use sharp objects on the surface of the touch screen. 7. Do not stack touch screens on top of each other without placing buffer protection

between them. See Fig. 18 for the wrong placing way without protection material for each touch screen. And Fig. 19 is the correct way to use a buffer material between two touch screens.

Fig. 18 Do not stack the touch screen on top of each other

Fig. 19 Place buffer between touch screens

8. Clean touch panel surface with soft cloth moistened with alcohol only. Do not use any

other solvent solutions.



9. When connecting ZIF type connector, ensure handling with care to prevent

compressions of the tail. Hold the stiffener part of the tail to prevent creasing the tail. See Fig. 20 the wrong way to hold the touch screen tail side without holding the stiffener, pushing force can easily bend the tail.

Fig 20 Handle with Care when connecting ZIF type connector



CHAPTER 3: Installing AMT Touch Screens

This guide shows how to correctly integrate AMT touch screen into your system. Correct integration is vital for the function performance of your touch system. We will discuss the various methods of mounting the touch screen to the front bezel, to the LCD module and with a graphic overlay. Before we proceed with the integration guide, we will introduce the meaning of the different dimensions in the touch screen and the LCD display unit.

3.1 Pre-installation Guide

3.1.1 Touch Screen The different dimensions of the touch screen are shown below in Fig. 21.

Fig. 21 Touch Screen Drawing

Outside Dimension: the overall external size of the touch screen is usually the glass substrate

of the touch screen. The overall size tolerance is specified and shown in the drawing of the touch screen..

View Area: this dimension is for the mechanical engineer to design the size of the front bezel opening for the display.



Active Area: this is the touch screen function area. Tail: is the touch screen circuit connecting line, there are 4-pin, 5-pin and 8-pin variations. Touch Screen Surface: the top side of the touch screen is the touch function side; the

material is a film; the surface of this film could be antiglare, clear or glare hardcoat surface. The touch screen surface should be facing outward.

3.1.2 LCD Display module: We will explain the usage of the different dimensions shown in Fig. 22 below.

Fig. 22 LCD Display Drawing

Outside Dimension: the overall external size of the LCD module which is the metal casing that houses the LCD panel and the PCB.

Bezel Opening: or known also as Opening Area. This is the LCD metal frame opening area; this metal frame has to be fully covered off by the system front bezel.

Active Area: is the display area of the LCD module. The touch screen active area should match this LCD active area.



3.1.3 Dimensional Measurements of Touch Screen and LCD Panel The touch screen view area should match with the LCD bezel opening area, and the active area of touch screen should match with the LCD active area. When aligning touch screen to the LCD display, or designing a new front bezel, make sure the touch screen silver bus line is fully covered off by the system front bezel. The touch screen view area is not allowed to be touched or come into contact with the front bezel of the system. Please refer to Fig. 23 below for further reference.

Fig. 23 Matching Touch Screen to LCD Panel



3.2 Installing Touch Screen The following illustration (Fig. 24) shows a typical integration method of our touch screen to your LCD display or system. We suggest that the front bezel edge fall close to active area of the touch screen. The bezel must not touch the view area of the touch screen; recommend utilizing gasket to create a gap. The front gasket opening must be larger than the Adhesive Opening, thus to prevent accidental pressing on touch screen. The gasket material should be a elastic material e.g. PORON. This would not be applicable if overlay foil is used.

Fig. 24 Typical Integration Method

3.2.1. Front Gasket The front gasket provides buffer to the touch screen when it is being squeezed tight to the front bezel; a single-side adhesive front gasket is recommended, do not use very high bond double-sided tape (VHB type adhesive). It is suggested that the front gasket be bonded to the touch screen perimeter. Please ensure that the view area of the touch screen are not enclosed / encased by the front gasket.

The gasket expands when compressed thus make sure it does not overlap into the viewing area of the touch screen. Compression force around the perimeter of the touch screen should be even. It must also be ensured that the front bezel itself does not come into contact with the view area of the touch screen. The thickness of the gasket is suggested to be less than 1.0 mm, except for special considerations or designs. See Fig. 25.

Fig. 25 Front Gasket Alignment

We suggest that the bezel edge not to come in contact with the view area to avoid disruptive contact with the function of the touch screens.



3.2.2. Bending, Routing and Connecting the Touch Screen Tail When connecting the touch screen tail to the connector, make sure to hold the housing of the tail. If the tail is designed to be ZIF type, there is a stiffener that is at the end of the tail terminator, hold the stiffener area and insert the ZIF type tail to the ZIF connector.

The following conditions are to be avoided when folding or inserting the touch screen tail into the LCD display module. a. Do not crease the tail as this can damage the conducting lines of the tail. See Fig. 26

Fig.26 Do not crease the tail

b. There must be no multiple bending or twisting of the tail. See Fig. 27

Fig. 27 Do not bend the tail

c. It is important to position the touch screen tail in such a way that its bent radius is greater than the tail specified bend radius. The minimum bend radius specification of each type of tail is as follows:

Fig.28 The bend radius specification of each type of tail



d. Avoid pulling the tail and bending the tail to minimize the risks of creating upward

stress from tail to touch screen. The tail should not pull, push or put any tension on the top sheet of the touch screen and it should not move freely after assembly.

e. Do not cut the tail. Check the tail route to ensure there are no sharp edges that comes in contact with the tail. The sharp edges can cut the tail’s protective film after a period of time due to vibration or transportation. This effect can cause the touch screen to open circuit.

Fig. 29 Avoid sharp edges comes in contact with Tail

f. Never route the touch screen tail around unshielded high voltage like the inverter or

power transformer. g. Ensure that the tail’s contact with the connector will not be loosened by vibration. h. Avoid bending at the PTH location of the tail.

3.2.3. Non-Input and Critical Area

An area along the boundary of active area is defined as Non-Input area in the Approved Drawing, must be protected from any force. The Critical Area should be free from using excess force especially with stylus input. Otherwise, will occur "non-linearity" issue.

Fig. 30 Avoid damage at Non-Input and Critical Area



3.2.4. Preventing Touch Screen Distortions AMT recommends mounting the touch screen to the LCD first. Do not use high adhesion of adhesive on the front surface of the touch screen. This recommendation will help to prevent distortion and pillowing that may develop due to ITO top film expansion in response to changes in temperature. When applying force to the touch screen perimeter, we must ensure it is uniform and evenly applied. If a gasket is used between the bezel and top ITO PET, it must be able to absorb expansion differences between the two surfaces. If the gasket is overly compressed, distortion may occur. The gasket must be positioned over the border.

Fig. 31 Gaskets to Prevent Touch Screen Distortion

The force from the front bezel to the touch screen surface, if unequal, can cause the touch screen to have pillowing effect. In order to avoid this, it is necessary to ensure the average force from the front bezel to touch screen surface is spread evenly around the perimeter of the touch screen. Also if there is a sharp residue from the front bezel that comes in contact with the touch screen top surface, it might cause squeeze the touch screen surface to shift from the original position, it also might cause pillowing occurred.

Fig. 32 Preventing Touch Screen Distortion



3.3. Mounting Methods There are 3 mounting methods for consideration: Front Mounting Rear Mounting Sandwich Mounting After mounting the touch screen, LCD module and front bezel, the side view is as shown at Fig. 33 below

Fig. 33 Touch screen integration side view

3.3.1 Front Mounting Design The LCD display modular is mounted to the underside of the bezel and the touch screen is mounted on to the front of the bezel and a graphic overlay over the touch screen. To design a frame that embeds the touch screen, the depth of this embedment is the total thickness of the touch screen with gasket if necessary. Due to the gaps and height tolerance between the touch screen and the housing, it is necessary for the graphic overlay to create an emboss design around the perimeter of the touch screen in order to overcome this optical problems, see Fig. 34 below.

Fig. 34 Design an emboss around the perimeter of the touch Screen



Do not use silicon glue to mount the touch screen to the bezel, as it will be very difficult to remove the touch screen from the housing when needed.

Fig. 35 Avoid using silicon to the touch screen

It is necessary to ensure the graphic overlay does not have very strong adhesive laminated on top of the touch screen. See Fig. 35 above, It is suggested to use two different type of adhesive for this integration, one is for touch screen that will be optical adhesive, and the other side of emboss area is the adhesive to hold the graphic overlay with bezel. When using Metal Alloy Housing or Plastic Housing

It is necessary to use a rear side adhesive that will allow you to remove the touch screen from the LCD module not difficulty when re-alignment is necessitated or warranty purpose. The display will get warm after a period of usage; therefore, select an adhesive that will perform well within the operating temperature range of the display and your application environment.

The rear adhesive or gasket is for prevention of dust and contamination from

getting in between the display and the touch screen backer. Thus the hardness and thickness of the gasket is a very important factor; the ideal rear gasket thickness is less than 1.00 mm thick with a minimum hardness of shore scale A50.

Never use low-density foam as rear gasket of touch screen for the touch screen

size larger than 12” or the touch screen has a thicker type glass backer, as there will not be enough support to the glass backer.



After mounting the touch screen into the designated area of the metal alloy or

plastic housing, the graphic overlay can now be mounted / laminated onto the front of the touch screen. During this process, it is necessary to ensure that there be no double-sided adhesive at the touch screen tail. The minimum clearance for the double-sided adhesive to these areas should be 1.5mm on each side. Refer to Fig. 36 below.

Fig. 36 Touch screen with graphic overlay

The plastic housing must be rigid enough to withstand any twisting force that may

occur to prevent the touch screen from getting damage or broken.

3.3.2 Rear Mounting Design The touch screen is mounted onto the LCD display and the front bezel is mounted on top of the touch screen.

It is necessary to use a rear adhesive that will allow you to remove the touch screen from the LCD module during repairs / maintenance of your system. The display will get warm after a period of usage; therefore, select an adhesive that will perform well within the operating temperature range of the display and your application environment.

The rear adhesive or gasket is for prevention of dust and contamination from

getting in between the display and the touch screen, it also performs as a buffer between touch screen glass and LCD metal frame. It is not necessary to use a thick gasket except the system is for certain purpose design. The thickness of the gasket is depended on the size of touch screen display. See Fig. 37.



Fig. 37 Use gasket to protect the touch screen

Consider to design several ‘ribs’ to the underside of the front bezel to hold the touch screen, see Fig. 38 below. The touch screen is placed inside the ribs area to hold the touch screen to prevent it from moving for slipping. By this way there would be no need for very high bond adhesive between LCD and touch screen or touch screen to front bezel.

Fig. 38 Design a rib to hold the Touch screen

Fig. 39 High possibly of breakage at pressure point



Do not design a rib made off hard material like metal to hold the touch screens, it can cause the touch screen to crakes at the pressure points due to uneven shear force created when it is being tighten.

When designing an integration system with metal rib, we would recommend

creating a rib around the perimeter to counter the uneven shear stress at the pressure points.

Not Recommended

Recommended

Do not use silicon glue to bond the touch screen to the front bezel as this will

cause difficulties in removing touch screen from the housing when necessary. If your application device requires water resistance, please consider to design

more protective method from the front bezel.



Never mount the touch screen to the underside of the front bezel directly when

there is no rear support to the touch screen. This may cause touch screen function or pillowing problems after certain period of usage.

It is recommended to apply a thin gasket on the front side of the touch screen as this acts as a buffer between the touch screen and the front bezel.



3.3.3 Sandwich Mounting Design

The touch screen is mounted onto and held by the front bezel and LCD module. Touch screen does not require front or rear adhesive. The integration layer is shown at Fig. 40

Fig. 40 Sandwich Design

The mounting order is: put the front bezel face downwards on a platform first, follow by placing the gasket inside the front bezel, then mount the touch screen, follow by LCD module, use screws to fix the LCD module to the front bezel.

Design several thick ribs inside the front bezel or design a thick front bezel frame to hold the touch screen and the LCD display module securely in place and avoid any movement to the touch screen. Normally, screws are used to clamp the LCD display module to the front bezel. The touch screen is held in place between the front bezel and the LCD module without any adhesive tapes.

A front bezel gasket is required to buffer the bezel from the touch screen; another gasket is required to buffer the rear of the touch screen from the LCD panel.

During fastening of the front bezel to the touch screen and LCD module, ensure force is applied evenly in order to prevent possible shifting or dislodgement of the touch screen top film which may cause poor performance.

If O-ring gasket is used for the front bezel, ensure that it does not generate any stress on the top surface of touch screen, such as torque force or twisting force from the compression force of the screws. See Fig. 41

Fig. 41 O-ring design



3.4 Protective Film After integrating the touch screen to the front bezel or graphic overlay, etc, if there is protective film requested to cover the touch screen surface, never use protective film with strong adhesive bonds on the touch screen; this can cause contact problems that may arise when tearing off the very high bond protective film from the touch screen and cause the top film to dislodgement from its glass backer. Use only low adhesive protective film to protect the touch screen. After the end user starts to use the touch screen system, please suggest end user to throw away the protective film. When use a protection film for the touch screen the adhesion force must not be greater than 3N/25mm. This is to prevent contact problems that may arise due to the de-lamination of the touch screen’s top film from the glass backer piece when tearing off the protection film.

Fig. 42 Do not use protection film with strong adhesive bond

Fig. 43 Correct type of protection film



Chapter 4: Low Reflective Touch Screen AMT provide two series of low reflective touch screens, Linear polarizer (LN) and Circular polarizer (CR) type. AMT’s LN series of touch screens utilize application of a polarizer film, and the CR series application of a circular polarizer film with or without additional quarter-wave film.

4.1 Absorption Axis Angle The design of the Low Reflective Touch Screen is dependent on your LCD display absorption axis angle. The common LCD displays come in either 45 or 135 degree absorption axis angle. It is very important know your selected LCD display absorption axis angle and not to install the low reflective touch screen. It is very important for us to know your selected LCD display absorption axis angle, only them we can select or design a proper low reflective touch screen for your application. If your LCD display comes in other absorption axis angles, we can modify our touch screen to match your LCD display.

However, to make the samples right the first time around, we are sending you a small piece sample that is named ‘LAAT’ (LCD absorption Axis tester that is a piece of glass laminated with a piece of polarizer film) to confirm your LCD absorption axis.

4.2 Linear Polarizer Touch Screens The LN touch screen is enhanced by additional of a polarizer film, resulting in superior application in handheld products with reduced weight, for smaller touch screens of 3” to 7”.

4.3 Circular Polarizer Touch Screen Circular polarizer touch screen uses a linear polarizer to convert incoming light to a specific direction, and the first layer of quarter-wave film further converts the light to a circular clockwise polarity. When reflected, the light is converted to a counterclockwise path and the reflected light is blocked by the polarizer film from exiting. Thus reflection is reduced considerably to less than 1.5%.

4.4 Checking and Handling When checking the Low reflective touch screen in incoming inspection ensure the orientation are correct. The touch screens are design with specified absorption axis angle to match the display LCD. Please be extra caution when handling the low reflective CR type touch screen products. To avoid scratches on the rear surface of the low reflective touch screen please ensure the rear side should not be rubbed, wiped or cleaned improperly.



Please note the rear quarter-wave retardation film can be scratch when improper cleaning methods are use. We recommend having the rear double-side adhesive tape to be carried out as option in AMT. In doing so we can attach the touch screen directly to the LCD immediately after peeling off the rear protective film. We do no recommend to have the rear of the touch screen wipe but unless it is necessary. 4.5 Installation Recommendation We recommend incorporating the design of the front bezel able to prevent liquid from seeping into the touch screens; prevent condensation from forming around the touch screens; This is very important for these low reflective touch screens retaining the special optical properties. Please ensure to follow the percentage of the humidity as stated in the approved sheet.

4.6 Care and Cleaning The low reflective touch screen requires very little maintenance like the normal touch screens. We recommend that you periodically clean the touch screen surface with dry soft cloth; only if necessary we would recommend the usage of Alcohol or Isopropyl Alcohol for difficult stain or sanitary purpose. When cleaning the low reflective touch screens do not spray the cleaning agent on the

screen itself, always dampen the cloth and clean the screen. After cleaning, make sure the surface is dry there must not be any left over solvent

seep into the display. It is very important to prevent water penetrating into the touch screen from the

perimeter cleaning. This can cause the touch screen to loss some of it’s special optical properties.

Do not use high-pressure air, water or steam to clean the surface of the touch screen. This action may cause the touch screen to mal-function.



4.7 Others The thickness of the low reflective touch screen is usually slightly thicker than our normal touch screen. Thus when changing from normal touch screen to low reflective type, please ensure the mounting system are not too tight. If so, this can cause the low reflective touch screen to have pillow. You may require changing gasket thickness.



Chapter 5: Capacitive Touch Screen The following illustration below shows a typical integration method of our capacitive touch screen to your LCD display or system.

Figure 44: Typical Integration method of capacitive touch screen

5.1 Front Bezel and Housing It is important to keep in mind that metallic materials can present a stray capacitive loading to the touch screens or recognized as a touch. The following guild lines must be followed when positioning the touch screen near conductive surface. This includes conductive paint that is used to apply on some of the plastic bezels; metal mounting brackets and screws. There must be no physically contact to the front or sides of the touch screens. We do not recommend metal housing and front bezel for this application. When this cannot be avoided it is very important not directly contact the touch screen. The design must be properly grounded and incorporate insulating material as sealing gasket between the front bezel and touch screen.

5.2 Sealing Gasket The sealing gasket material is best to be an insulating material. Ensure the gasket only comes in contact with the perimeter of the touch screen and does not interferes with the viewing are. We recommend single-sided adhesive on the front bezel instead of on to the touch screen surface.



5.3 Mounting Tape The main functions of the Mounting Tape are to hold the touch screen in position and to maintain a constant distance between the touch screen and the LCD panel. The mounting tape must have a minimum thickness of 1.6mm and not easily be compressed from touch forces or temperature changes. It is necessary to leave 1 ~ 2mm ventilation holes at corner, this is to allow hot air to escape to avoid temperature and pressure equalization issue. The touch screen must be mounted in a very stable manner and failure to following the instructions this may result in reduced accuracy.

5.4 Tail Routing It is important to position the touch screen tail in such a way that its bent radius is greater than 1.5mm. Avoid pulling the tail and bending the tail to minimize the risks of creating upward stress from tail to touch screen. The tail should not pull, push or put any tension on the top sheet of the touch screen and it should not move freely after assembly. Apply tape to secure the tail in a manner that does not apply stress to the tail Never route the touch screen tail around unshielded high voltage like the inverter or power transformer. Ensure that the tail’s contact with the connector will not be loosened by vibration.



CHAPTER 6: Touch Screen Care and Cleaning The touch screen requires very little maintenance. We recommend that you periodically clean the touch screen surface with dry soft cloth, only if necessary we would recommend the usage of Alcohol or Isopropyl Alcohol for difficult stain or sanitary purpose. When using other solvent or cleaning agent, be sure to follow the manufacturer’s precautions and instruction. It is very important to avoid using any other chemical on the touch screen. Always dampen the cloth and clean the screen. We must not spray the cleaning agent

on the screen itself, the drips can seep into the display or stain the bezel. After cleaning, make sure the surface is dry there must not be any left over solvent

seep into the display. It is very important the handle the touch screens with care, do not use excess

squeezing or pushing force when cleaning. Do not use sharp material to clean the touch screen surface Do not use high-pressure air, water or steam to clean the surface of the touch screen.

This action may cause the touch screen to mal-function. When the ketchup, food or drink drop on the surface, clean it immediately Please check with the graphic overlay vendor on how to clean the touch screen when

there is graphic overlay over of touch screen. It is necessary to prevent water penetrating into the touch screen from the perimeter

especially the tail area during cleaning.

Important Notice for Low Reflective Touch Screen (CR Type):

We advice our clients to be extra caution when handling the low reflective touch screen

products. It is recommended to attach the touch screen directly to the LCD immediately after

peeling off the rear protective film, unless necessary use a soft cloth lightly wipe the surface for

cleaning.

Note : Chemical Test had been carried out on the surface of our touch screen.
