What kind of LED display can be called HD_LED display manufacturer|Huaze Optoelectronics

What is a high-definition LED display is defined relative to the 'high-definition' commonly used by our TVs. The division of the two comes first from the video effects that can be seen. Due to the difference in image quality and bandwidth occupied by channel transmission, digital TV signals are divided into HDTV (high definition television), SDTV (standard definition television) and LDTV (ordinary definition television). In terms of visual effects, HDTV has the highest specifications. 1. In terms of picture quality, the resolution of high-definition LED display is basically equivalent to 4 times that of traditional analog TV, and the picture definition and color reproduction are far better than traditional TV. For example, when the original standard definition broadcasts football matches, the football field is green, while the high-definition signal will let you see that the green space is made up of green grass. The 16:9 widescreen display also brings a wider visual enjoyment. From the perspective of audio effects, high-definition TV programs will support Dolby 5.1 channel surround sound, and high-definition movie programs will support Dolby 5.1 True HD specifications, which will bring us super shocking listening enjoyment. 2. 720P is the format standard for high-level high-definition digital television formulated by the Society of Motion Picture and Television Engineers (SMPTE). The effective display format is: 1280×720. Divided into 1080P, 1080I, 720P (i is interlace, meaning interlace, p is Progressive, meaning progressive). 720P is a display format that achieves a resolution of 1280×720 under progressive scan. It is the fusion of digital film imaging technology and computer technology. 3. 1080i and 720p are both internationally recognized digital high-definition television standards. The original NTSC countries used the 1080i/60Hz format, which is the same as the NTSC analog TV field frequency. Some countries in the original PAL system, such as Europe and China, have adopted the 1080i/50Hz mode, and the field frequency is the same as that of PAL analog TV. As for 720p, it has become an optional standard due to the deeper penetration of IT manufacturers into the TV industry. At present, it has begun to expand its territory in the field of HDTV players using optical discs as the carrier. ①1080i format high-definition LED screen, resolution 1920×1080i/60Hz, line frequency 33.75kHz; 　②720p format high-definition LED display, resolution 1280×720p/60Hz, line frequency 45kHz; 　③1080p format high-definition LED screen, resolution It is 1920×1080 progressive scan, professional format.　　 It can be seen from the above that the 720P format high-definition LED display must meet the resolution of 1280*720, and the 1080P high-definition LED display must meet the resolution of 1920*1080.
