1. Que es Plasma? El Plasma puede ser acelerado o girado por campos magneticos o elctricos lo que permite que sea controlado y utilizado. Las investigaciones sobre Plasma nos estan llevando a una mejor comprensin de nuestro universo. Tambin nos provee de muchos usos practicos: new manufacturing techniques, costumer products and the prospect of abundant energy.Ex.) Lightning, Aurora, Nebula, Flames, Neon Sign, Solar core . Plasma ?Plasma es la forma ms comn de materia.El Plasma en las estrellas y en el espacio tnue entre ellas compone ms del 99% del universoVisible y probablemente la mayor parte de aquello que es invisible.

Plasma es una coleccin de electrones-libres en movimiento y atomos-ionizados que hanperdido electrones. Energia es necesaria para separar electrones de sus atomos y crear asi Plasma. La energia puede ser de varias fuentes: termal, elctrica, o lumnica (luz ultravioleta o luz intensamente Visible de un laser). Con poca energia de sostenimiento, el plasma se re-combina para formar gas natural. Solido Liquido Gaseoso Ion, Electron : 4to Estado de materia Best LG with Best Technology

2.What is Plasma Display Panel (PDP)?(1) Como trabaja?La Pantalla de Plasma ademas de ser alta tecnologia es la mejor forma de fabricar pantallas totalmente planas con excelente calidad de imagen y de gran tamao, facilitando la visibilidad en cualquier ambiente. PDP es un arreglo de celdas conocidas como pixeles, los cuales estan compuestos de 3 sub-pixeles, comprendiendo los colores Rojo, Verde y Azul. Un gas en el estado de Plasma reacciona with el fsforo en cada uno de los sub-pixeles para producir luz de colores (rojo, verde y azul). Estos fsforos son iguales a los usados en los dispositivos de Tubo de Rayos Catodicos (CRT) tales como televisores y monitores de computadora convencionales. Se obtiene los colors vivos y dinamicos que se espera. Cada sub-pixel es controlado individualmente por una electrnica avanzada para producir ms de 16 millones de diferentes colores.Todo esto significa que usted obtiene magnificas imgenes que son faciles de observar en una pantalla de menos de 6 pulgadas de grosor.Gas DischargeYUV GenerateVisible IlluminateDisplayScan(Y) ElectrodeSustain(Z) Electrode(MgO)2Best LG with Best Technology

ISM ( Image Sticking Minimization )Aparte de de las ventajas ya mencionadas, este modulo viene equipado con un mtodo especial para minimizar el fenomeno de la imagen pegada.Cuando el modulo permanece con una imagen fija por largo tiempo, el brillo de la pantalla decrecera poco a poco durante 10 minutos. Abajo se muestraUna grfica en donde el brillo est decreciendo poco a poco sin que el usuario se percate del cambio.MODO ISM (Modo de Minimizacion de Fijacvion de ImagenTIEMPO (Minutos)
