1. What is HDR
HDR: High-Dynamic Range (HDR) Rendering (English High-Dynamic Range, HDR for short) The real existing brightness difference, that is, the ratio of the brightness of the brightest object to the brightness of the darkest object is 10 to the 8th power, and the human eye The range that can be seen is about 10 to the 5th power, but the general display, the camera can only show 256 different brightness.
What is 2.4K
4K TV is a TV product with a screen physical resolution of 4096×2160 pixels. It can receive, decode, and display video signals with corresponding resolution. The resolution is 4 times that of 2K TV. The viewer can see every detail in the screen. A close-up, with an immersive viewing experience.
The difference: 4k is 4 times the pixel 1080p It is the pixel rate to improve the clarity, but HDR is a very different technology, which is mainly reflected in the way it changes the picture. Under the influence of HDR, the colors presented by the TV are more vivid, the black is deeper, and the objects on the screen are clearer. At the same time, the hue of the picture is also enlarged, alternating between cool and warm colors.
3 Why 4k+HDR can make the visual experience reach the limit?
Four-color HDR is an HDR technology applied to televisions. It adds HDR algorithms for four-color 4K screens, solid color 4K technology and HDR technology on the basis of ordinary HDR.
The four-color HDR technology controls one white sub-pixel more than the normal HDR to enhance the screen brightness. 4K technology improves the number of pixels, and HDR technology improves the quality of pixels. Based on the HDR image quality, HDR is converted into 4-color HDR.
Four-color 4K hard screen technology, under the condition that the human eye can perceive the color difference of 0.02, thanks to the different arrangements of the liquid crystal, the 4 color 4K hard screen can reach the color viewing angle of 142 degrees, beyond the traditional VA LCD screen. °, in a wider angle, the picture color is not distorted, and the viewing of "dead ends" is basically eliminated.
Under the same backlight brightness, the three-color screen body must achieve the same four-color 4K screen display brightness, it needs R/G/B three primary colors to be greatly enhanced, which will cause the screen display to be overexposed, and eventually the picture will appear white, even if The brightness of the screen is up to standard, and it will not necessarily show a better HDR screen. The 4 color 4K screen body, by adding HDR algorithm in the T-con driver, the R/G/B tri-primary colors increase the brightness without losing the saturation, while the white sub-pixels are greatly increased in amplitude, so that the final display The picture does not appear overexposed, but it performs better in terms of color.
The smart brain of developers makes science and technology more powerful and amazing.
