2015 is arguably the hottest year for 4K TV. Compared with curved TV, the high definition of 4K TV will bring us more clear and intuitive reality. The emergence of 4K technology can be said to be the most important technological advancement after the Full HD era. It is well known that the physical resolution of 4K TVs has increased by 4 times compared to 1080P Full HD TVs, which means 3840x2160, which means that the fineness of the picture is the same in the leap type of the same size. Promote. However, the biggest problem with 4K TV is the high cost and it is difficult to reduce costs in the short term.
In the short term, since it is difficult to solve the cost problem and want to speed up the popularization of 4K products, the current solutions are mostly based on alternative approaches, such as the 4-color 4K solution provided by LG. In general, colors and even pictures are composed of three colors of red, green, and blue RGB, whether it is the picture tube or the liquid crystal. The key to the 4-color 4K panel is the addition of a white pixel, RGBW, to the RGB technology. The benefits of doing so increase the number of pixels and objectively increase the fineness of the panel. Another benefit is the effective increase in panel brightness, which makes the TV brightness appear higher than the RGW panel.
However, the biggest drawback of the RGBW panel is that the white pixels do not directly participate in the composition of the screen structure, but they use an algorithm to simulate color, so the actual effective resolution does not reach the level of 3840x2160. The physical pixel of a real 4K TV is about 8.3 million pixels, and the RGBW panel color pixels are about 6 million. The actual effect is still slightly different. In addition, due to the brightness of the white pixels, the color uniformity of the picture is not as good as the RGB three-color panel. In fact, the RGBW panel itself is positioned as a low-cost 4K panel. The overall fineness is close to 4K but not 4K. As for the color, the manufacturer's own level of adjustment.
The RGBW panel can not be said to be useless. This is a specific product in a specific period. Just like CD-RW and DVD-ROM competed for the market in the past, the appearance of Combo is only an expedient measure, and DVDRW eventually dominates the world. The RGBW panel, like these historic products, is a low-cost, nearly 4K solution for this high-cost 4K era. At present, many cheap 4K TVs use similar products. It is not always easy to find them if they are not at close range or viewed with special pictures.
Therefore, the pursuit of 4K TV can be completely considered from the actual demand. If there are not a large number of 4K sources in the short term, the true 4K TV cannot fully play its outstanding fine performance, and it is not always necessary to see various 4K demonstrations every day. For a variety of pseudo-4K, RGBW panel TV users, pseudo 4K is not necessarily a bad thing, at least a lot more clear than 1080P.
The core of LCD TVs lies in the panel itself. For enterprises that do not have panel production R&D capabilities, outsourcing panel is a must and the only solution. For example, LG, Samsung, Chi Mei, and Huaxing Optoelectronics are well-known panel makers in the industry. In particular, LG not only produces and sells to third-party companies for television through LGD, but also supplies it to its own television.
This is a bit like Mitsubishi Motors, which has equipped its own cars with MIVEC technology engines. On the other hand, it sells the engines to many domestic brands. This is a win-win solution. Is it true for panel makers such as LGD or even Samsung? The so-called true and false 4K, is only a marketing tool for manufacturers, of course, if you sell this panel to the real 4K price, how much is a little kind.
