Cardi asSmart Conference TableManufacturer, is a research and development, production, sales in one of the enterprises, with LCD industry more than 12 years of experience in research and development team!

W-white white light R-red light G-green green light B-blue light;

RGB is often said true 4K, RGBW is to add a white pixel of false 4K, white pixels only increase the role of brightness, the actual resolution is not up to 4K, but low cost;

The so-called WRGB is in fact the OLED version of RGBW, is not what tall on the black technology, its launch purpose and RGBW, in order to meet the low-cost market to launch castration products;

From the principle of light, color oled is RGB three-color mixed light, which is the most basic idea, but the big screen, especially the TV-grade large screen yield is touching, it is said that LG is using pure white light oled bottom with polarizing film to color, so that in fact, compared to LCD has no color advantage;

The common lg four-color screen 4k is to use w this pixel to get 4k pixels, the actual resolution is not as good as RGB's true 4K, RGBW technology on the basis of R/G/B, added white sub-pixels, that is, RGBW LCD panel has 4 colors of sub-pixels. Reduces the number of sub-pixels that make up the entire pixel while increasing the number of white sub-pixels. For example, originally consisting of 3 sub-pixels as a pixel point, now changed to 2 or 2.5 sub-pixels, and by the two or 2.5 sub-pixels of the color ratio to display the color. Less than three subpixels cannot display rich colors, so its display also requires a fit between adjacent pixels. The final picture will certainly be fine-tuning a certain discount, not to achieve the real 4K effect. Several of Skyworth's 43-inch models are RGBW screens.
