  •      Since the development of the LCD screen, the size of a single screen has been unable to meet the needs of many enterprises, LCD splicing screens have appeared, and are widely used in the market.
  •  
  •      The LCD splicing screen can be used as a display alone or as a large screen. According to different use requirements, it can realize variable and large variable and large screen functions: single screen split display, single screen separate display, any combination display, full screen LCD stitching, double stitching LCD screen stitching, vertical screen display, image border Optional compensation or cover, support digital signal roaming, zoom stretching, multi-screen display, various display plan settings and operation, full HD signal real-time processing.
  •  
  •      The LCD splicing screen is composed of multiple displays, and sometimes there are some problems, such as chromatic aberration. Mainly in the color or brightness of a certain part of the screen is inconsistent. So, how to avoid the problem of chromatic aberration?

  •   LCD splicing screen color difference causes and solutions to resolve: 
  •  
  • 1. The reason for the color difference of LCD splicing screen:
  •  
  •      The color difference is mainly caused by the wavelength difference between the LEDs, which is caused by the difference in the photoelectric physical properties between the LED individuals, and cannot be changed later.
  •  
  •      Individually, the difference in brightness and chromatic aberration is mainly due to the manufacturing process. The photoelectric parameters of each LED are not completely consistent. Even in the same batch, the brightness may be 30% to 50%. deviation.
  •  
  •      Since LED is a self-illuminating body, the luminous intensity is proportional to the current supplied in a certain range, so the driving current also affects the brightness difference during the design, fabrication, installation and debugging of the circuit.
  •  
  • 2. LCD splicing screen color difference solution:
  •  
  •      Selecting the same batch of led can largely control the difference and ensure the consistent color, which can basically meet the actual needs of many LED manufacturers.
  •  
  •      Use a professional spectrophotometer to screen, select a display with similar color brightness, and use a small enough difference on a display screen to achieve good results.
  •  
  •      KONWHAI splicing screens are all composed of high-definition LCD screens. The picture quality is clear, the colors are pure, and there are many factory inspections. There are few problems, and they can withstand long-term tests, giving users a shocking visual experience.
