EL ESTADO DE PLASMA

El plasma es por mucho la forma ms comn de la materia.

El plasma en las estrellas y en el espacio constituyen ms de 99% del universo

visible y quizs la mayora de lo que no es visible.

El plasma consiste en una coleccin de electrones de libre movimiento

e iones de tomos que han perdido electrones.Se necesita energa para despojar electrones de los tomos y hacer plasma. La

energia puede ser de varios origenes : trmica, elctrica, o luz (ultravioleta

o la intensa luz visible de un lser).

El plasma puede acelerarse y ser dirigido por campos elctricos y magnticos quepermiten controlarlo y aplicarlo. La investigacin del plasma est rindiendo una

comprensin mayor del universo..

Tambin proporciona muchos usos prcticos: nuevas tcnicas industriales,

productos para el consumidor, y la perspectiva de energa abundante.

EL ESTADO DE PLASMA

El elemento central en una luz fluorescente es el Plasma, un gas compuesto de

iones con libre movimiento (tomos cargados elctricamente) y electrones(partculas cargadas negativamente).

Bajo condiciones normales un gas se compone principalmente de partculas no

cargadas. Esto significa que cada tomo de gas incluye igual nmero de

protones (partculas positivamente cargadas en el ncleo del tomo) yelectrones. Los electrones negativamente cargados equilibran perfectamente a

los protones positivamente cargados, as que el tomo tiene una carga neta de

cero.

Si se introducen muchos electrones libres en el gas por medio de un voltajeelctrico a travs de l, la situacin cambia muy rpidamente. Los electrones

libres chocan con los tomos, al golpearlos libern otros electrones. Con un

electrn perdido, un tomo pierde su equilibrio, Ahora tiene una carga neta

positiva, convirtiendolo en un ion positivo.En un plasma con una corriente elctrica que lo atraviesa, las partculas

negativamente cargadas estn apresurndose hacia el rea positiva del

plasma, y las partculas positivamente cargadas estn apresurndose

hacia el rea negativa.


7/1557/74

EL ESTADO DE PLASMA

Las partculas estn chocando constantemente entre ellas. Estas colisiones

excitan los tomos de gas en el plasma, originando la liberacin de fotonesde energa.


8/1558/74

LA CELDA DE PLASMA

En su forma ms 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 delgas. 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 direccin positiva ( + ) (no el lado cargado

positivamente) es mostrado en la figura y la direccin negativa es la designadapor el signo negativo ( - ).


9/155

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 Seal 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 seenciende el gas.

Esto es solo la medio ciclo.

Vfs se desconecta y Vs se pone en cero (0) por un instante y slo hay un voltaje

en el interior de la celda (V1) qu es igual a 1/2 Vfen ese instante y ningn voltaje

externo (Vs), cuando el generador cambia de d ireccin hay una cantidad de

electrones y carga positiva en el interior de la celda (V1).

Al sumar los voltajes V1+Vs obtenemos Vfnuevamnete 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 ltima tecnologa de pantallas y la mejor manera de lograr

imagenes con calidad excelente y los tamaos grandes visibles en cualquierambiente.

El PDP puede verse como un descendiente de la lmpara de nen y tambin

ha sido sido modelado como una serie de lmparas fluorescentes. PDP es unaserie 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 Fsforo en

cada uno de los sub-pixeles para producir luz de color.

Estos Fsforos 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 dinmicos que espera. Cada sub-pixel es controladoindividualmente por electrnica avanzada para producir ms de 16 millones de

colores diferentes. Todos esto significa que usted consigue imgenes

perfectas que son fcilmente visibles en una pantalla que tiene menos de 5

pulgadas de grueso.


11/155

LA CELDA DE PLASMA

Los electrodos transparentes estan rodeados por un material dielectrico y son

cubiertos por una capa protectora de xido de magnesio, estan montados sobrela 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 direccin se colocan en columnas verticales, los electrodos verticales y horizontales forman una reja bsica (matriz).


12/155

12/74

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 pequeo

fragmento de segundo, cargando cada celda a la vez.

LA CELDA DE PLASMA

Variando los pulsos de corriente a travs de las diferentes celdas, el sistema de

control puede aumentar o disminuir la intensidad de cada subpixel de color paracrear centenares de combinaciones diferentes de rojo, verde y azul.

R8303- on AC-DC Board(10W 4.7 Ohm)

=> They can be damaged from in-rush

current

2.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 terminalof 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 doesnt operate, it is Fan Fail Mode. In this case, you can forcibly stop

Power off operation by Fan Fail Mode by connecting two pins-Yellow wire and Black wire connected-of connector

on VSC Board which defect Fan connected.

LED(D017) on VSC Board warns you Fan Fail Mode.(In Fan Fail Mode, LED turns on.)

hole at U300 side Change Control Board

Vertical bar in every20mm


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.


145/155

1. Because Control data on PROM(U40)

doesnt download to FPGA, it cant

generate control signal to X,Y and Z

Board.

2. Defected ALTERA.

Replace Control BoardReplace PROM


- When Power On, Fan operatesbut No OSD displays

- LED(D3) of Control Board

doesnt operate


146/155

12/21


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


Control Board

Replace Controller board

normal Red signal.

Symptoms Cause Countermeasure

1. CN1 on Vs Board cold

soldering2. Spark marks between CN1

and Vs Board -> It makes

them open

Replace DC-DC 2 board


148/155

14/21

Vs board1. No Raster(ST-BY LED On)

2. Spark noise(Tik-Tik)3. No Vs, Vsetup & Vsc


1. Check Vs, Va with multimeter(No Vs output)2. Separate SMPS Board and VSC Board and check all voltage output

stage

3. Check FET, TR, Diode and Resistor(especially Cement Resistor)

4. Observe PCB Pattern and soldering condition with naked eyes


1. PCB pattern of OVP circuit is wrong

(In some SET)2. The discharging time of Vsetup is long,

if Power On again within discharging

time, this remaining voltage is

considered as pulse and shut down

Power toggles(On and Off)

Replace DC-DC2

board

considered as pulse and shut down

control circuit

Defected SET : OVP Circuit


1. Power On/Off function doesnt work Initial Power On OK

2. Power On : - Fan operates normally - No Vsetup & Vsc of Module

3. Only Module operate : No Vs,Vsetup & Vsc
