Entering the high-definition era, first of all, it is necessary to clarify what is high-definition. High-definition LED display is defined by "high-definition", which is commonly used in current TV sets. 1080i and 720p are internationally recognized digital high-definition TV standards, so the 1080i format has a resolution of 1920×1080i/60Hz, a line frequency of 33.75kHz, and a 720p format with a resolution of 1280×720p/60Hz. The frequency is 45kHz, the 1080p format, the resolution is 1920×1080 progressive scan, and the professional format display can be defined as a high-definition LED display.

  High-definition LED display to achieve high-definition must mean that the dot pitch of high-definition LED display is getting smaller and smaller. Reducing the dot pitch of high-definition LED display can greatly improve its clarity, and the more delicate the screen display; secondly, the contrast also affects One of the key factors of visual effects, generally speaking, the higher the contrast, the clearer and more striking the image, and the brighter and brighter the color. Contrast has a greater impact on the display effect of dynamic video. Because the light and dark transition in dynamic images is faster, the higher the contrast, the easier it is for human eyes to distinguish such a transition process.

   In the ultra-high-definition era, the substitution effect will be strengthened

   Under the call of the ultra-high-definition era, with the maturity of small-pitch high-definition LED display technology and the changing needs of users, more and more end users choose small-pitch high-definition LED displays, traditional applications of DLP projection and LCD panel splicing screens Scenes, such as hotels, venues, exhibitions, monitoring centers, etc., will gradually be replaced by high-definition LED displays. In the past, the large-screen splicing market was relatively low-end, just upgrading and transforming the traditional desktop LCD display and applying it in the market, there are many drawbacks, such as insufficient resolution, it is difficult to reach the level of 1080p, and DLP projection in the The lack of color performance and the overall stability to be strengthened have created opportunities for the development of LED displays. Then there are products that can only be seen from a distance.

  There are obvious differences between high-definition LED display technology and DLP projection, LCD panel splicing screen and other display technologies. The biggest highlight of small-pitch high-definition LED display is the visual experience. Display technologies such as backlight and projection operate due to materials and lightThe color loss and deviation caused by the path, the scientific light and color mixing design, the point-by-point correction technology, realize the true color reproduction, and with the maturity of the seamless display technology, the high-definition LED display can achieve no slight seam, Like a seamless plane, the picture quality is vivid and the image is intact. The large-screen display system is used as the front-end display layer of the emergency command center, hotel, venue, exhibition, and monitoring center. The quality of the display effect directly affects the display of the functions of the business platform, which indirectly affects the efficiency of command and dispatch work, the image display effect, etc. , The ultra-high-definition LED display has become a powerful force that cannot be ignored with more and more significant technical advantages, long service life, and wide adaptability to the environment.
