EL ESTADO DE PLASMA
EL ESTADO DE PLASMA E jemplos.) El Relámpago, Aurora, Nebulosa Nebulosa, Llamas, Señal de Ne Neón, Núcleo Solar,…
EL ESTADO DE PLASMA El 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 neta positiva, 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.
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 fotones de 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 ( - ).
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 voltaje en el interior de la celda (V1) qué es igual a 1/2 Vf en ese instante y ningún voltaje externo (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 también ha sido sido modelado como una serie de lámparas fluorescentes. PDP es una serie de celdas conocidas como pixeles que estan compuestas de 3 subpixeles, correspondiendo a los colores rojo, verde, y azul. El Gas en un estado de plasma se usa para reaccionar con Fósforo en cada 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 de colores diferentes. Todos esto significa que usted consigue imágenes perfectas que son fácilmente visibles en una pantalla que tiene menos de 5 pulgadas de grueso.
LA CELDA DE PLASMA Los 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 vertical es, los electrodos verticales y horizontales forman una reja básica (matriz).
LA CELDA DE PLASMA Para 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.
LA CELDA DE PLASMA Los 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 y el átomo se calienta, cuando el electrón regresa a su nivel normal, suelta energía en 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.

PD-40X2 uses 4 board such as left,right, top and bottom. Divide the screen in 5 and once you see ADD BAR check COF CONNECTOR between MODULE and X-BOARD. If there is no defect in COF CONNECTOR replace X-BOARD. But the problem still remains and check the connector between X-BOARD and CONTROL BOARD. And if you can’t find defect, check CONTROL.

Vertical bar in every 20mm
Check Check Point Point 1. Measure the resistance of Via holes between U3 and U300 at Control Board and compare with that of normal.(Normal : 2~3 ) 2. Resistance increases as temperature rises.
Symptom
Cause
- Open circuit between pin 7 of U200 and pin 7 of U7 - Resistance between two pins varies from 19 ohm ~ 45Kohm
Check Check Point Point 1. Observe the symptom during Heat-Run at 45 degree. 2. Check the resistance of VIA holes of suspect ICs
Countermeasure
Replace Control Board
Symptom
Cause
- When Power On, Fan operates but No OSD displays - LED(D3) of Control Board doesn’t operate
1. Because Control data on PROM(U40) doesn’t download to FPGA, it can’t generate control signal to X,Y and Z Board. 2. Defected ALTERA.
Check Check Point Point 1. Check D1, D3 & D4 on Control Board - D1 : ON with 5V - D3 : ON when PROM finishes program download from ALTERA chip - D4 : ON when signal is applied

Countermeasure Replace DC-DC 2 board
Symptom
Power toggles(On and Off)
Cause
Countermeasure
1. PCB pattern of OVP circuit is wrong (In some SET) 2. The discharging time of Vsetup is long, Replace DC-DC2 if Power On again within discharging board time, this remaining voltage is considered as pulse and shut down control circuit
Defected SET : OVP Circuit
Check Check Point Point 1. Power On/Off function doesn’t work Initial Power On OK 2. Power On : - Fan operates normally - No Vsetup & Vsc of Module 3. Only Module operate : No Vs,Vsetup & Vsc
