How to define indoor high-definition led display

Now many TVs have developed high-definition channel satellite TV, and high-definition channels are generally only broadcast on indoor high-definition LED displays. Speaking of indoor high-definition display.

what is the difference between it and ordinary display?

How is indoor high-definition LED display defined?

What is an indoor high-definition LED screen is defined relative to the “standard definition” commonly used in our TV sets. The division of the two comes first from the video effects that can be seen. Due to the different image quality and bandwidth occupied by channel transmission, digital TV signals are divided into HDTV (high-definition television), SDTV (standard-definition television) and LDTV (general-definition television). In terms of visual effects, HDTV has the highest specification.

In terms of picture quality, the resolution of high-definition LED displays is basically four times that of traditional analog TVs, and the picture clarity and color reproduction are far superior to traditional TVs. For example, when the original standard definition broadcasts a football match, the football field is green, but the high-definition signal will let you see that the green field is composed of green grass. The 16:9 widescreen display also brings a wider visual enjoyment. In terms of audio effects, high-definition TV programs will support Dolby 5.1-channel surround sound, and high-definition video programs will support Dolby 5.1 True HD specifications, which will bring us super shocking listening enjoyment.

720P is the format standard of high-level high-definition digital TV formulated by the Society of Motion Picture and Television Engineers (SMPTE), and the effective display format is: 1280×720. 1080P, 1080I, 720P (i is interlace, meaning interlaced, p is Progressive, meaning progressive). 720P is a display format that achieves a resolution of 1280×720 under progressive scanning. It is the fusion of digital film imaging technology and computer technology.

1080i and 720p are both internationally recognized digital HDTV standards. The original NTSC country adopts the 1080i/60Hz format, which is the same as the NTSC analog TV field frequency. While some original PAL countries such as Europe and China have adopted the 1080i/50Hz mode, the field frequency is the same as that of PAL analog TV. As for 720p, it has become an optional standard because IT manufacturers have penetrated deeper into the TV industry. At present, it has begun to expand its territory in the field of HDTV players based on optical discs.

1. 1080i format high-definition LED screen, the resolution is 1920×1080i/60Hz, and the line frequency is 33.75kHz;

2. 720p format high-definition LED display with a resolution of 1280×720p/60Hz and a line frequency of 45kHz;

3. 1080p format high-definition LED screen, the resolution is 1920×1080 progressive scan, professional format.

It can be seen from the above that the 720P format HDTV must meet the resolution of 1280*720, and the 1080P HDTV must meet the resolution of 1920*1080.
