P. 12Emerging Display - HKPC Nov2008

Cholestric Liquid Crystal (ChLCD)Low Magnitude Pulse

Large Magnitude Pulse

Bright: Planar state

Dark: Conic state

Intermediate state

P. 13Emerging Display - HKPC Nov2008

QR-LPD

Similar to EPD, but use air instead of liquid

P. 14Emerging Display - HKPC Nov2008

Electrowetting

No voltage applied:

Oil spreads in the cell

=> display color of oil

Voltage applied:

Oil pushed aside

=> display color of underlying reflective surface

P. 15Emerging Display - HKPC Nov2008

Flexible OLED! OLED laminated at the flexible TFT substrate

Flexible substrate by thin metal or organic material

P. 16Emerging Display - HKPC Nov2008

Emerging display

Advantages

P. 17Emerging Display - HKPC Nov2008

Advantages of E-paperBistable = Bright and Dark (two stages)

Stable = No power to keep display state

Flexible & Thin (200um)

Simple Manufacturing! EPD: Roll to roll

P. 18Emerging Display - HKPC Nov2008

Advantages of ChLCD

Bistable, no power

Flexible

Different choice of mono color

Memory Device

P. 31Emerging Display - HKPC Nov2008

Display on a USB thumb drive

! When the drive connected to the computer though the USB connector

! MCU will update write\read the Flash memory.

! MCU got the flash memory capacity information during data transaction.

! MCU control SSD1623 to output a corresponding driving waveform.

! SSD1623 drives the EPD to show the capacity information
