Its general appearance is composed of many small red lights, and the characters are displayed by the light on and off. Used to display text, graphics, images, animation, market, video, video signals and other information display screen.Traditional LCD TV backlight is CCFL, now a new backlight LED, is organic light, TV can be thinner, almost no difference in functionNotice that it says TVNotebook all used LED n years ago! Because of the thin notebook requirements, a few years ago to now see all laptops are ledThe reason why LED is so hot now is that Samsung has just come in to push LED backlight TV. In fact, it's not a new technologyTraditional LCD is a long line of CCFL behind, which can't be controlled independently, so it can't emit light partiallyLED is organic light-emitting, the lamp can be controlled separately, can do part of the light-emitting, that is, can achieve high contrast.In fact, they all have the same display principle: backlight + lower polarizer + TFT + middle liquid crystal + CF + upper polarizerDifference of light emitting body: the backlight used to be CCFL, which is the same as our fluorescent lamp. It has to be arranged in a row below, so it is very thick. Now it is changed to LED, which is organic light emitting. It only needs to be installed on the side, and the light guide plate is enough. So it is very thin..
