The extremely high resolution brings a delicate display effect. In the demonstration film, the high-altitude lens can almost reflect the whole picture of a city.
In addition to resolution, the pixel density of ultra-high-definition LCD TVs is as high as 103ppi. Although this indicator is only one third of the iPhone 4 screen, it is already much higher than the 36ppi of today's 60-inch 1080P TVs.

In 2012, China's first 8K ultra-high-definition 84-inch large-screen TV was born. With a physical resolution of 7680 × 4320 (8K4K), the total number of pixels in its display device is over 8 million, which is 8 times that of Full HD and 16 times that of HD. The TV is thinner and thinner, and the picture is more delicate. The ultra-high-definition panel uses a new light transmission technology to achieve high-precision liquid crystal molecular control and higher liquid crystal aperture ratio, making blacks more black and whites brighter. Its unprecedented high contrast under precise light control is the perfect embodiment of the new generation of ultra-high-definition LCD screen technology. The 84E99UD's LED backlight uses a direct-type backlight. Compared to edge-type LED backlights, the light projected on the LCD screen is more uniform. While ensuring sufficient brightness of the screen, it also extends the life of the LED backlight. [1]
