One -time explanation 8K display
The innovation of technology always happens to the laboratory and production lines we can't see, but when it appears in front of us, it shines the light of the times. The saying of "the light of the times" is placed in the depiction of 8K technology. As we all know, video technology has been developing rapidly. The most intuitive is the videos we are watching every day. From the "slag picture quality" in the past, to today's "ultra -high -definition", it is witnessing the advanced road of video clarity. Essence
What is 8K display? The current widely popular 4K TV resolution is 3840 × 2160, about 8 million pixels. The resolution of 8K TV reaches 7680 × 4320, which is about 33 million pixels, which is 4 times that of 4K TVs. The color saturation, delicateness and layering of the screen have all improved. "The biggest defect displayed in the past is the lack of layering. The depth of the picture is not strong. 8K just makes up for this shortcoming. Its image effect is realistic, rich in layers, and can show a natural 3D three -dimensional sense."
'K'
2K, 4K, 8K, etc., represents the "total number of video pixels", such as 4K, indicating that there are 4000 pixel numbers in the video, which are 3840 or 4096 columns. The number of pixels with 4K resolution is usually 3840*2160 or 4096*2160.
?
'P'
720p, 1080P, etc., which means "the total number of video pixels", for example, 720P indicates that the video has 720 lines of pixels, while 1080P indicates that there are 1080 pixels in the video. The 1080P resolution camera usually is 1920* 1920** 1080. "P" itself means "scanning", which is the abbreviation of Progressive, compared to intermediate.

The truth of 8K is the same as 4K. If you are talking about the display, the horizontal pixels and vertical pixels are twice the 4K display: 7680 × 4320. But the number of 8K video sources is not large, and we have become mainstream far away from 8K.
In the industry, it is known that 8K, also known as QUHD technology, has a resolution of 7680 × 4320. In terms of display effect, it is 4 times that of 4K display, which is 16 times that of the current mainstream HD (FHD) resolution. Based on the standard of normal human eyes, at the standard of 1.0, 8K TVs allow people to have 4.3 times the high -definition visual experience.
In the 8K era, isn't LCD or OLED?
At present, the 8K TVs sold in the market are mainly LCD display technology. However, from the perspective of productization, the same size LCD panel changes from 4K to 8K standards. In terms of opening rate performance, the pixel structure of the LCD display will be reduced by 40%, which is essentially a frame and filling LCD material. Under the current material and boxing process, the thickness of this frame is almost impossible to decrease further for large size panels. This determines that the screen can be used for the area of LCD material that can be used for light transmittance, and it decreases a lot after the pixel density increases.
The use of light transmittance is reduced by 40 %, which means that the backlight power is increased by 60 %: Therefore, the new version of the TV energy efficiency standard is especially prepared "one version" for 8K TV.
Similar principles are also suitable for OLED TV products. The OLED panel is made of steaming plating or inkjet printing process. The two factors of large -sized and high -density will significantly increase product costs, reduce the rate of finished product, and reduce unit panel light. This also makes OLED TVs, which are currently adopted 8K standards .In fact, OLED TVs still sell for 4K products.
In addition to LCD and OLED TV, laser TV is another 8K choice. Theoretically, the large -size advantage of laser TV is also the most suitable for 8K applications. Because only large -sized pictures can truly play the sharpness advantage of 8K high resolution. However, 8K laser TVs are still far away: because of projection technology -based laser display, light valve products will also increase technical difficulty or price with resolution.
