What kind of LED display can become a high-definition display?

In the era of high-definition, we must first define what is high-definition. The high-definition led display is defined by the high-definition digital TV set by the American Society of Motion Picture and Television Engineers (SMPTE). Format standard, while 1080i and 720p are internationally recognized digital high definition television standards, so 1080i format, resolution is 1920 × 1080i / 60Hz, line frequency is 33.75kHz, 720p format, resolution is 1280 × 720p / 60Hz, OK The frequency is 45kHz, 1080p format, the resolution is 1920×1080 progressive scan, and the professional format display can be defined as high-definition led display.
To achieve high definition of LED display, it means that the dot spacing of LED display is getting smaller and smaller, and the dot pitch of LED display can be reduced, which can improve the clarity of the LED display, and the finer the picture display; secondly, the contrast is also affecting the visual effect. One of the key factors is that the higher the contrast, the sharper and more conspicuous the image, the brighter and brighter the color, and the higher contrast is helpful for the sharpness, detail, and gray level performance of the image. Contrast has a greater impact on the dynamic video display. Because the light and dark transitions in the dynamic image are faster, the higher the contrast, the easier it is for the human eye to distinguish such a conversion process.
