Where is the gap between domestic LED display technology and foreign countries?

      In terms of technology, the development of LED displays must closely follow the quality characteristics of world-class companies. The current domestic high-quality LED displays and foreign top products have little difference in image processing technology, front-end video processing technology, etc. The main gaps are as follows Two aspects.

 


 
 

 1. Single-point color confirmation: The "single-point color confirmation" technology can ensure a vivid color display, which can last for several years.

 

At present, domestic products can only adjust the unit module and the unit cabinet, and cannot achieve true single-point adjustment. Therefore, there are differences in color and brightness consistency, especially after the display unit has been repaired and replaced, due to the LED The parameters may have changed, and the display effect is difficult to be consistent with the original screen. This work is done by special large-scale equipment abroad, and there is no such equipment developed due to product characteristics in China. It is also hoped that social related industries And equipment manufacturers can give attention.


 
  

In the module, the LED tube in each pixel has its own color and brightness value. These light-emitting diodes must be accurately measured when installed in the factory. These data are stored in the EEPROM in each module at the same time. When the display signal is processed, the digital processor (DIGITIZER) will read the information from each EEPROM, and correct the brightness and color differences of the LEDs to ensure that the display effect reaches the best consistent state.

 

2. Structural technology: At present, the cabinet shells of domestic products are basically processed by a single piece of sheet metal, with poor processing technology, low precision, unsightly appearance, and poor waterproofness, especially in harsh outdoor environments. Easy to cause system instability.

 

  The box is suitable for harsh working environment. All the external hardware of the box is installed in the aluminum alloy casting box with IP65 standard. The special sealing measures adopted in the box are sufficient to prevent the entry of rainwater and dust. The number "5" is the level to prevent liquid infiltration, and it is also one of the design requirements, so that the display system can work normally in rainy weather and no water.

 

   my country’s LED display technology research and development still has a long way to go. The long-term development strategy for enterprises is to focus on the road of research and development.
