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

The dead light rate of the traditional LED display is tens of thousands of times in the industry standard, but the small-pitch LED small display is still not possible for the time being. If according to the previous standard, there is one dead light in 10,000 square meters, then the display is almost impossible to read. Therefore, the dead light rate of the small-pitch LED display must be controlled at one in 100,000 or even one in a million to meet the needs of long-term use.

Small-Pitch LED Display

Achieve low brightness and high gray

Many people know that the human body sensor light is different from the outdoor display that requires high brightness, refresh rate and energy saving requirements. The indoor display needs to reduce the brightness. Experiments show that from the perspective of the sensitivity of the human eye, the LED brightness is twice that of passive light sources. As far as the specific data is concerned, the best brightness of small-pitch LEDs entering the room is 200-400cd/m2. However, the grayscale loss caused by reducing the brightness needs to be completed through technical supplements.

Standard resolution with source

Different from outdoor display, outdoor advertisers will choose suitable content and display according to the resolution of the display screen. Indoor display signal sources have certain standards. As LED display manufacturers, they cannot require access to indoor signal sources. It is necessary to adapt to the resolution of the display screen, but to adapt to the needs of indoor signal sources, and design and guarantee the corresponding resolution, so as to meet the needs of users as much as possible.

Support multi-signal and complex signal system access and display control

Compared with outdoor display signals, small-pitch LEDE display signals are characterized by multi-signal access and complex signal access, such as multi-site video conferences, which require remote access signals, local access signals, and multi-person use. Experiments have shown that simply implementing multi-signal access through a split-screen solution will reduce the signal standard. Therefore, how to solve the problem of multi-signal and complex signal access still needs technical support from small-pitch LEDs.

Achieve seamless patchwork and high-speed correction

The biggest advantage of small-pitch LED displays is seamlessness, but the requirements for splicing are relatively high. For liquid crystals, as long as the seams are uniform, there is no problem, and the seams are not obvious. However, the small LED spacing cannot be like this. If the modules are too tightly squeezed, bright lines will appear, and if the modules are separated, 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 to a certain extent.
