EL ESTADO DE PLASMA
El plasma es por mucho la forma más común de la materia. El plasma en las estrellas y en el espacio constituyen más de 99% del universovisible y quizás la mayoría de lo que no es visible.
El plasma consiste en una colección de electrones de libre movimientoe iones de átomos que han perdido electrones.Se necesita energía para despojar electrones de los átomos y hacer plasma. La energia puede ser de varios origenes : térmica, eléctrica, o luz (ultravioleta o la intensa luz visible de un láser).
El plasma puede acelerarse y ser dirigido por campos eléctricos y magnéticos quepermiten controlarlo y aplicarlo. La investigación del plasma está rindiendo una comprensión mayor del universo..
También proporciona muchos usos prácticos: nuevas técnicas industriales,productos para el consumidor, y la perspectiva de energía abundante.

EL ESTADO DE PLASMAEl elemento central en una luz fluorescente es el Plasma, un gas compuesto de iones con libre movimiento (átomos cargados eléctricamente) y electrones(partículas cargadas negativamente).
Bajo condiciones normales un gas se compone principalmente de partículas no cargadas. Esto significa que cada átomo de gas incluye igual número de protones (partículas positivamente cargadas en el núcleo del átomo) y electrones. Los electrones negativamente cargados equilibran perfectamente a los protones positivamente cargados, así que el átomo tiene una carga neta de cero.
Si se introducen muchos electrones libres en el gas por medio de un voltaje eléctrico a través de él, la situación cambia muy rápidamente. Los electrones libres chocan con los átomos, al golpearlos liberán otros electrones. Con un electrón perdido, un átomo pierde su equilibrio, Ahora tiene una carga netapositiva, convirtiendolo en un ion positivo.
En un plasma con una corriente eléctrica que lo atraviesa, las partículas negativamente cargadas están apresurándose hacia el área positiva del plasma, y las partículas positivamente cargadas están apresurándose hacia el área negativa.
7/74
EL ESTADO DE PLASMA
Las partículas están chocando constantemente entre ellas. Estas colisiones excitan los átomos de gas en el plasma, originando la liberación de fotonesde energía.

LA CELDA DE PLASMA
En su forma más simple, una celda de Plasma consiste en dos placas de vidrio separadas por un espacio lleno de gas. El color es dependiente de la mezcla del gas. En las caras Internas de las placas estan dos electrodos transparentes fijos horizontal y verticalmente cubiertos por una capa delgada de vidrio aislante.
Los electrodos se conectan a una fuente de poder, esta fuente genera corriente alterna al modelo de carga. La dirección positiva ( + ) (no el lado cargado positivamente) es mostrado en la figura y la dirección negativa es la designada por el signo negativo ( - ).
9/74
LA CELDA DE PLASMA•La fuente de poder genera un Voltaje de Sostenimiento (Vs – sustain voltage) igual a medio Voltaje de Encendido (1/2Vf - firing voltage ) para la mezcla gas.
•Para encender la celda es necesario una Señal de Encendido (Vfs - firing signal voltage) igual tambien a 1/2 Vf.
•Una vez que esto ocurre las dos cantidades se suman ( Vs + Vfs = Vf ) y se enciende el gas.
•Esto es solo la medio ciclo.
•Vfs se desconecta y Vs se pone en cero (0) por un instante y sólo hay un voltajeen el interior de la celda (V1) qué es igual a 1/2 Vf en ese instante y ningún voltajeexterno (Vs), cuando el generador cambia de d irección hay una cantidad de electrones y carga positiva en el interior de la celda (V1).
•Al sumar los voltajes V1+Vs obtenemos Vf nuevamnete y la celda se enciede.
•Vfs firing signal voltage : es solo necesario para iniciar el encendido
•Cambiar el voltaje (Vs) de las paredes de cristal mantiene encendida la celda

LA CELDA DE PLASMA
EL PDP es la última tecnología de pantallas y la mejor manera de lograr imagenes con calidad excelente y los tamaños grandes visibles en cualquier ambiente.
El PDP puede verse como un descendiente de la lámpara de neón y tambiénha sido sido modelado como una serie de lámparas fluorescentes. PDP es una serie de celdas conocidas como pixeles que estan compuestas de 3 sub-pixeles, correspondiendo a los colores rojo, verde, y azul.
El Gas en un estado de plasma se usa para reaccionar con Fósforo encada uno de los sub-pixeles para producir luz de color.
Estos Fósforos son del mismo tipo que los usados en el “CRT” para los dispositivos como televisiones y monitores de computadora. Usted obtiene los colores vivos y dinámicos que espera. Cada sub-pixel es controlado individualmente por electrónica avanzada para producir más de 16 millones decolores diferentes. Todos esto significa que usted consigue imágenesperfectas que son fácilmente visibles en una pantalla que tiene menos de 5pulgadas de grueso.
11/74
LA CELDA DE PLASMALos electrodos transparentes estan rodeados por un material dielectrico y son cubiertos por una capa protectora de óxido de magnesio, estan montados sobre la celda a lo largo de la placa frontal de vidrio.
Los electrodos para despliege de imagen se colocan en filas horizontales a lo largo de la pantalla y los electrodos de dirección se colocan en columnas verticales, los electrodos verticales y horizontales forman una reja básica (matriz).
12/74
LA CELDA DE PLASMAPara ionizar el gas en una celda particular, el ordenador de la pantalla carga los electrodos que se cruzan en esa celda, esto lo hace miles de veces en un pequeño fragmento de segundo, cargando cada celda a la vez.
13/74
LA CELDA DE PLASMALos fotones ultravioletas liberados interactúan con el material de fósforo que recubre la pared interior de la celda. El fósforo es substancia que emite luz cuando se le expone a otra luz. Cuando un fotón ultravioleta golpea a un átomo del fósforo en la celda, uno de los electrones de fósforo salta a un nivel de energía más alto yel átomo se calienta, cuando el electrón regresa a su nivel normal, suelta energíaen forma de fotón visible.

LA CELDA DE PLASMA
Variando los pulsos de corriente a través de las diferentes celdas, el sistema de control puede aumentar o disminuir la intensidad de cada subpixel de color para crear centenares de combinaciones diferentes de rojo, verde y azul.

Estructura Asimétrica de la Celda
PDP es innovador en su estructura de la celda asimétrica (anchura diferente delfósforo) esto mejora el equilibrio luminoso de los tres colores primarios, produciendo un brillo alto y puro, un blanco vivo con temperatura de color alta.

current2.Check R8538,R8539 & R8540 on DC-DC Board (10W 6.8 Ohm)3.Check the connection of 4 Sub-PackASSYs of AC-DC & DC-DC Board.4.Check between Va of P8012 and GND and Vs and GND, respectively(ON & OFF condition)
-.Va Voltage(Normal) : 165 ~ 175Vdc-.Vs Voltage(Normal) : 65 ~ 80Vdc
5.Check between 5V and GND terminal of P8011.* If 5V/Va/Vs terminals are short to
GND, there is some problem on Drive of PDP module.
Check DC-DC Board of PDP module.
* If any fan out of three fans located above doesn’t operate, it is Fan Fail Mode. In this case, you can forcibly stopPower off operation by Fan Fail Mode by connecting two pins-Yellow wire and Black wire connected-of connectoron VSC Board which defect Fan connected. LED(D017) on VSC Board warns you Fan Fail Mode.(In Fan Fail Mode, LED turns on.)

Trouble Shooting GuideX - Board COF Connector separationLift up the right and left of X-BOARD CONNECTOR.
When you handle COF CONNECTOR, don’t pressure. First release LOCK and separate.If COF CONNECTOR is damaged you should replace MODULE ASS’Y. so be aware of this!!

Lift up X-BOARD CONNECTOR and separate COP CONNECTOR by pulling up.
warningwarning
When you exchange X-Board, first you should separate COF Connector. Be careful not to damage it. COF Connector is attached to Module. Since COF Connector is torn, Module Ass’y must be replaced a new one. Be careful!
