The physical resolution of 4K TV is 3840 * 2160; 4 times of Full HD (FHD. 1920 * 1080); 9 times of HD (HD. 1280 * 720).
The physical resolution of 4K TV is 3840 * 2160; 4 times of Full HD (FHD. 1920 * 1080); 9 times of HD (HD. 1280 * 720). Compared with other large screen terminal displays, LED display has the following characteristics:
1. High brightness: the brightness of outdoor LED display is more than 8000mcd / m2, which is the only large-scale display terminal that can be used outdoors all day; The brightness of indoor LED display is more than 2000md / m2
2. Long life: the life of LED is more than 100000 hours (ten years). This parameter generally refers to the design life, even if the brightness is dark
3. Large viewing angle: the indoor viewing angle can be greater than 160 degrees, and the outdoor viewing angle can be greater than 120 degrees. The size of the viewing angle depends on the shape of the LED
4. The screen area can be large or small, from less than one square meter to hundreds or thousands of square meters;  
5. Easy to interface with computer and rich supporting software

What is the difference between LED and HDR



HDR (high dynamic range) means "high dynamic range", which is popularized later in the field of display, but in fact it is not a new technology. HDR technology can expand the brightness range, improve the contrast of the brightest and darkest pictures, so as to obtain a wider range of colors. It can not only improve the gray scale, but also bring a darker or whiter color effect. It can be said that the display equipped with HDR technology can be comprehensively improved in sRGB, brightness and color expression, and its impact on image quality is very obvious
