Ultra HD refers to information recently approved by the International Telecommunication Union showing "

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.

Many devices now support 4K UHD resolution (such as Onkyo TX-NR809 amplifier, NHK has been working on 4K UHD program transmission technology), but

UHDTV is the abbreviation of (Ultra High Definition Television), which stands for "Ultra High Definition Television", and is the next generation technology of HD (High Definition) and Full HD (Full High Definition). "Ultra HD" released by the International Telecommunication Union (ITU)

For TV, picture quality is the core. Only with excellent picture quality performance can consumers really attract the attention of consumers.

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]
