Now the development of science and technology is faster. The speed of product upgrading is declining at a constant speed. The TV screen commonly used in our family is becoming larger and larger, and its functions are becoming more and more. Now there is a 4K screen TV in the market, which is very clear. Its resolution is 8 times of HD and 4 times of Full HD, but the price is also relatively expensive, so there are many pseudo 4K screens in the market. If you can't tell, you'll be angry if you buy fake goods.
How can we tell the truth from the false?
Many people think that to distinguish the real and fake 4K screens, it needs professionals. We ordinary people can't distinguish at all. In fact, we can do it if we want to distinguish.
As long as a mobile phone can do it, we just need to put the mobile phone close to the TV screen, then take a picture, and enlarge the picture to quickly verify the true and false. If you enlarge the picture, you can see the red, green and blue, that is, RGB three colors. The real 4K screen is arranged orderly.
If the screen is red, green, blue and white, that is, RGBW is arranged in four colors, it is a pseudo screen, that is, SK screen, with 8294400 pixels. Although there are so many pixels in the pseudo 4K screen, there are only a quarter of the pixels that display black and white colors, that is, w effective pixels, with a gap of only 6220800 pixels. The result is that the color display effect of the real 4K screen is better than that of the pseudo 4K screen.
Pseudo 4K screen color display effect is much worse, and the screen is brighter, the result is that the time is long, watching TV eyes will feel uncomfortable.
Most importantly, the real 4K screen price is also much more expensive than the fake 4K screen price. If we buy the wrong one, we will waste a lot of money, so we must check it with mobile phone to see if it is true.
This is a very simple way to distinguish the TV screen. Everyone can try it.
