Advantages of small-pitch LED display:
One of the advantages: reduce the dead-light rate of the display lamp and ensure the stability of the main body of the screen
The dead-light rate of traditional LED displays is in the tens of thousands of industry standards, but small displays with small-pitch LEDs cannot be completed temporarily. If according to the previous standard, there is a dead light at 10,000 square meters, it is almost impossible to read the display. Therefore, in order to meet the needs of long-term use, the dead-light rate of small-pitch LED displays must be controlled at one hundred thousand percent or even one millionth. Otherwise, if a large number of dead lights appear within a period of time, it is absolutely impossible. acceptable
Advantage 2: Realize low brightness and high gray scale
Many people know that human body induction lamps are different from outdoor displays that require high brightness, refresh rate and energy saving requirements. Indoor displays need to reduce the brightness. Experiments show that from the perspective of human eye sensitivity, the brightness of LED (active light source) is twice that of passive light source. In terms of specific data, the large brightness of the small-pitch LED entering the room is 200-400cd/m2. However, the grayscale loss caused by the brightness reduction needs to be solved by technical supplements
Advantage 3: Standard resolution with signal source
Unlike outdoor displays, outdoor advertisers will choose suitable content and displays based on the resolution of the display. Indoor display signal sources have certain standards. As an LED display manufacturer, you cannot require that the indoor signal source to be accessed must adapt to the resolution of the display, but to meet the needs of the indoor signal source, please design and ensure the corresponding resolution, so as to meet the needs of users as much as possible
Advantage 4: Supports access and display control of multi-signal and complex signal systems
Compared with the outdoor display signal, the display signal of the small-pitch LEDE display has the characteristics of multi-signal access and complex signal access, such as multi-site video conferences that require remote access signals, local access signals and multi-point access. Human use. The access experiment shows that the realization of 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 requires the technical support of small-pitch LEDs.
Advantage 5: Realize seamless splicing and high-speed correction
The biggest advantage of small-pitch LED displays is seamless, but the requirements are higher when splicing. For LCD, as long as the seams are uniform, there is no problem, and the seams are not obvious. However, this is not the case for small-pitch LEDs. If the module is packed too tightly, bright lines will appear, and when the module is removed, black lines will appear. Therefore, splicing is not easy. Therefore, the process and calibration technology of the cabinet, as well as the guarantee of efficiency and good combination, need to be given a certain guarantee.
