Why HD led video wall is so popular?
♥HD led video wall is mainly used in commercial areas, such as enterprise meeting room, chairman’s office, network video conference, information demonstration needs of schools and educational institutions. They are attracted by high brightness, no seam, light and flexible, and small installation space. HD video wall is a general term for a complete set of high-end systems, which is also equivalent to a high-level summary, including LED display system, HD display control system and heat dissipation system, etc. the process is also very strict in the production process. Small spacing LED display screen is also the name of fine picture quality, which promotes the development of LED display screen to the indoor application field, and the market continues to heat up. Small spacing LED display screen came out, beat the large LCD screen, because LCD needs to be solved by splicing, but no matter how good splicing technology, it can not solve the gap problem.
1. Low brightness and high grayscale
♥Many people know that indoor and outdoor LED video walls are different. Indoor led video wall needs to reduce brightness. The experiment shows that the brightness of LED (active light source) is twice that of passive light source in terms of the sensitivity of human eyes.
In terms of specific data, the large brightness of the HD led video wall entering the room is 200-400cd / m2. However, the gray loss caused by brightness reduction needs to be solved by technical supplement. In 2016, the test samples of HD led video wall were released, and the test methods and standards were given. After testing, the results show that only a few LED display manufacturers can do it at the same time: low brightness and high gray level, most manufacturers just make some improvements.
2. High contrast, faster response, high refresh rate
♥The higher the scanning times and the refresh rate, the better the stability of the displayed image (picture). The lower the refresh frequency is, the more image flickers and shakes, and the more tired the eyes are.
HD video wall in high refresh, stable picture, no ripple black screen, clear image edge, accurate restoration of image real information.
High contrastLow contrast3. Standard resolution with signal source
♥Different from outdoor LED video wall, outdoor advertisers will choose suitable content and led wall according to the resolution of LED wall. The indoor display signal source has certain standard. As the manufacturer of LED video wall, you can’t require that the indoor signal source must adapt to the resolution of LED wall, but to meet the needs of indoor signal source, please design and ensure the corresponding resolution, so as to meet the needs of users as much as possible. Fortunately, after more than one year’s understanding of indoor LED video wall and customer needs, jdx has completed this transformation, which greatly meets the needs of most users.
4. Support multi signal, complex signal system access and display control
♥Compared with the outdoor display signal, the display signal of HD video wall has the characteristics of multi signal access and complex signal access, such as multi site video conference requiring remote access signal, local access signal and multi-point access. Access experiments show that multi signal access only through the split screen scheme will reduce the signal standard. Therefore, how to solve the problem of multi signal and complex signal access also needs the technical support of HD video wall.
5. Seamless splicing and high speed correction
♥The biggest advantage of HD video wall is seamless, but the splicing requirements are higher. For LCD, as long as the seam is even, there is no problem and the seam is not obvious. However, this is not the case for HD video walls. If the module package is too tight, there will be bright lines, and when the module leaves, there will be black lines. Therefore, splicing is not easy. Therefore, the process and calibration technology of the box body, as well as the guarantee of efficiency and good combination need to be guaranteed.
JDX Other 6. Good color restoration
♥It adopts the international leading point by point correction technology and the LED light-emitting principle to completely retain the authenticity of color, avoid the color loss and deviation caused by other display technologies such as backlight projection material and light operation path, and realize the true color reproduction.
