As early as 2014, the China Household Electrical Appliances Association pointed out that there are so-called “fake 4K TVs†using RGBW panels on the market. Because the resolution of these panels cannot reach 3840 2160, consumer trust is lost.
4K chaos
The rapid increase in demand for UHD TVs is not unrelated to its ultra-high resolution.
The reporter learned from panel industry insiders that the resolution of the 4K panel is 3,842,160 full RGB pixels, which is equivalent to 4 times the FHD (Full-HD) TV panel, which can solve the problem of dynamic image irregularity and enhance the color brightness. .
Among them, "K" in "4K" is the first letter of English "kilo" (thousands), which represents one thousand, and 4K is 4,000, which means that there are about 4000 pixels in the horizontal direction. For convenience of calling, 3840 pixels are called Make 4K. The UHD (Ultra-HD) TV refers to a TV with a screen resolution and a pixel number that is 4 times higher than that of a normal FHD (Full-HD) TV. Here, the pixel consists of three sub-pixels RGB: red (R), green (G), and blue (B), and the three primary colors display various colors through matching of different proportions.
However, with panel makers attacking the market at low prices, TV panels using RGBW (RedGreen Blue White) have appeared in the domestic market, that is, white sub-pixels have been added to the RGB color standard. The core of this technology is to reduce the RGB pixels while improving the brightness. RGBW can reduce the number of backlight components, so you can reduce costs.
However, the “cost†of reducing the cost is that due to the increase of white sub-pixels, the original RGB effective pixel number is insufficient, and the brightness of other colors except white is reduced and the color development is not uniform. In particular, the screen is not clear enough when displaying lines, borders, etc.
In April 2014, the China Household Electrical Appliances Association pointed out: “In order to save material costs, there are fake 4K on the market. Although the number of sub-pixels is the same as 4K, it is not a true 4K, so consumers should pay attention when buying. The method of distinguishing is: "Fake 4K can be recognized by eyes, and false 4K is blurred in color. If you look in a magnifying glass, you can see the white line."
Tested and compared, so that the RGBW TV model, although the label is 4K (3840 2160), but the actual resolution is only 4K resolution 3/4 (2880 2160), can only reach 3K standard. It is understood that currently UHD TVs such as Sony's Samsung and other foreign brands, and Hisense all adopt RGB mode, but there are still some domestic brands using RGBW panels. In fact, at the DisplaySearch China Flat Panel Display Conference in 2014, panel makers told reporters that nearly 40% of the 4K panels in the market accounted for nearly a quarter of the market at that time. The average cost is approximately 4K. 10~20 dollars.
Judging from the ex-factory price of panels, the price of 3K products is about 15% lower than that of 4K products. If they can be sold at a price of 4K, manufacturers can obtain additional revenue.
Standard competition
For the RGB and RGBW who are the real UHD TVs, there are two very different views in the electronics industry: one view is that RGBW is a technological innovation, and the other view is that such a product is actually a “fake UHDâ€.
Those who support RGBW believe that although there are differences in performance, the "RGBW mode" can provide consumers with low-cost products and help promote the development of UHD TV market.
A person with a critical attitude believes that because the actual pixel count of RGBW is insufficient, the resolution is only 3/4 of the 4K resolution. This variant product should be called 3K TV. If the variant's 3K is sold at a price of 4K, there is suspicion of deceiving consumers.
An industry source told reporters that at present, when many manufacturers are scheming to improve the image quality of 4K TVs, there are also some manufacturers who aim to brush up the volume of shipments with the idea of ​​puerile, and nearly 4K panels will enter the market in the global market. Pulling down the quality image of domestic 4K panels will limit the consumption of similar 4K panels to a battle of consumption, but it is necessary to do so for a healthy market environment to prevent bad money from driving out good money. In fact, the standard about 3KUHD TV has also caused discussion abroad, but now, RGBW does not mean UHD's claim has prevailed.
In March 2014, the German Institute of Electrical Engineers (DE) tested UHD televisions using RGBW panels and concluded that they did not meet the UHD resolution standard. The Consumer Electronics Association of America (CEA) and the European Association of Household Appliance Manufacturers (DE, DigitalEurope) also believe that non-RGB subpixels should not be included in the resolution. DE introduced relevant certification marks to issue certification marks for real 4KUHD TVs.
It is reported that China is one of the countries with the most sales of RGBW. The reason for this is not unrelated to the lack of Chinese 4K TV standards.
