What is the reason for the inconsistent brightness of folding LED displays?

  As the production technology becomes more and more sophisticated, folding LED displays have become an essential tool in many occasions, both indoor and outdoor, they are able to display excellent visual effects. However, sometimes when we use folding LED display industry, we will find that the brightness on the folding LED display is not consistent, which will not only affect the quality of the picture, but also may affect the audience's understanding and acceptance of the content. So do you knowFolding LED DisplayIs there a reason for inconsistent brightness? The following Vishay Technology editorial is for you:

  Reasons for inconsistent brightness of folding LED displays:

  I. Uneven quality of LED lamp beads

  LED beads are the basic components that make up the folding LED display, and their quality directly determines the brightness and uniformity of the screen. Some low-priced LED lamp beads have the problems of uneven quality and big difference in brightness. When in use, in order to reduce costs, some manufacturers may use different brands or batches of LED lamp beads, which will easily lead to the phenomenon of inconsistent brightness.

  Solution:

  Choose a reliable quality foldable LED display vendor and explicitly request the use of LED lamp beads with stable quality. In addition, pay attention to consult whether the vendor will carry out strict brightness correction and color matching before the finished foldable LED display leaves the factory.

  Second, power supply stability issues

  The brightness of the folding LED display is not only related to the quality of the LED beads, but also to the stability of the power supply. If the output current of the power supply is not stable, then the brightness emitted by the LED beads in different areas will be inconsistent. In addition, when the size of the folding LED display is large, the long-distance power transmission is also prone to cause voltage reduction, resulting in uneven display effect.

  Solution:

  Folding LED display should use a stable power supply equipment to ensure the stability of the output current. Minimize the power transmission distance, or use cable enhancement technology in long-distance transmission to provide stable voltage.

  III. Inaccurate color calibration

  Color calibration is the key to ensuring luminance consistency in folding LED displays.The key component. An accurately calibrated screen ensures that every pixel unit across the screen is consistent in brightness and color. However, less accurate color calibration can be a major cause of brightness inconsistencies due to the manufacturing process and shipping of the finished screen.

  Solution:

  When purchasing a folding LED display screen, explicitly ask the supplier whether it has undergone strict color calibration. In addition, if the screen has inconsistent brightness during use, you can use a professional color calibration instrument to make adjustments.

  IV. Temperature effects

  Temperature changes are also one of the potential causes of inconsistency in the brightness of folding LED displays.The luminous efficacy of LED lamp beads is greatly affected by temperature, and when the temperature is too high or too low, the brightness of LED lamp beads may be inconsistent.

  Solution:

  Keep the working environment temperature of the folding LED display stable, try to avoid too high or too low temperature on the screen. Heat sinks can be set up around the screen to ensure good heat dissipation.

  In summary, we can see that to solve the problem of inconsistent brightness of folding LED display, you need to start from the quality of the LED lamp beads, power supply stability, color calibration and temperature and so on, through these measures are able to a certain extent, effectively improve the consistency of the brightness of the folding LED display to achieve a better display effect.
