There must be something that makes LCD technology succeed in doing this. And to explain it, let’s talk about LCD Color TV in details.

With this decreasing dimension, automatically the production cost will also be decreased. That’s why many manufacturers prefer to produce this kind of television than others.

But now, most of the LCD display employs LEDs to generate black and colored images. Here, you will find millions arranged LCD shutters that close and open allowing lights to get through. Each shutter pairs with colored filters, forming sub-pixel. Each sub pixels will forms pixels, and finally they will generate images on screen.
Besides the energy efficiency, image quality also becomes the plus point of LCD Color TV.

Moreover, with the small size of sub pxiels, the image will appears in amazing details. Therefore, many people prefer to use this kind of display to fill their entertainment sector of their house.
