Reduce the dead light rate of display lights and ensure the stability of the screen

The dead light rate of traditional LED displays is 1 in 10,000 in the industry standard, but fine pixel pitch led displays still cannot do it for the time being. Therefore, the dead light rate of the fine pixel pitch led display must be controlled at 1/100,000 or even 1/100,000 to meet the needs of long-term use. Otherwise, if a large number of dead lights appear for a period of time, users can not accept.

Realize low light and high gray

Many people know that human body induction lights are different from outdoor displays that require high brightness, refresh rate, and energy-saving requirements. Indoor displays need to lower the brightness. Experiments show that from the perspective of human eye sensitivity, LED (active light source) brightness is twice that of passive light sources. As far as specific data is concerned, the optimal brightness of small-pitch LEDs for indoor use is 200-400cd/m2. However, the loss of grayscale caused by reducing brightness needs to be completed through technical supplements.

Standard resolution with the source

Different from the outdoor display, outdoor advertisers will select suitable content and display it according to the resolution of the display screen. The indoor display signal source has certain standards. As an LED display manufacturer, it cannot be required to adapt to the resolution of the display screen, but to adapt to the needs of indoor signal sources, and to design and ensure the corresponding resolution, so as to meet the needs of users as much as possible.

Support system access and display control of multiple signals and complex signals

Compared with outdoor display signals, small-pitch LEDE display signals are characterized by multi-signal access and complex signal access, such as multi-location video conferences, which require remote access signals, local access signals, and multi-person use. For access, experiments have shown that simply implementing multi-signal access 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.

Achieve seamless seams and high-speed corrections

The biggest advantage of fine pixel pitch led displays is that they are seamless, but they have higher requirements when splicing. For liquid crystals, as long as the seams are uniform, there is no problem, and the seams are not obvious. But the small spacing of LEDs cannot be like this. If the modules are squeezed too tightly, bright lines will appear, and when the modules leave, dark lines will appear. So it is not easy to splice well. Therefore, the process and calibration technology of the cabinet, as well as the guarantee and good combination of efficiency, need to be guaranteed.
