What effect does high temperature work have on the large LED screen? With the increasing application of LED large screens, in order to give full play to the advantages of large screens, users should understand the maintenance of large LED screens. Whether it is an indoor LED large screen or an outdoor LLED large screen, heat will be generated during the working process, and the generated heat will increase the temperature of the LED large screen. However, do you know the impact of high temperature operation on large LED screens?

     Under normal circumstances, large indoor LED screens generate less heat due to low brightness and will naturally dissipate heat. However, due to the high brightness of the large outdoor LED screen, a large amount of heat is generated, which needs to be dissipated by air conditioners or axial fans. Because the LED large screen is an electronic device, the increased temperature will affect the attenuation of the LED lamp beads, thereby reducing the working efficiency of the driver IC and shortening the service life of the LED large screen.

     LED large screen open circuit failure: The operating temperature of the LED display exceeds the load temperature of the chip, which will quickly reduce the luminous efficiency of the large screen, causing obvious brightness attenuation and damage; the large LED screen is mainly made of transparent epoxy resin . For packaging, if the junction temperature exceeds the solid phase transition temperature, the packaging material will turn into rubber, and the thermal expansion coefficient of the LED large screen will rise sharply, causing the LED large screen to open circuit failure. Excessive temperature will affect the light attenuation of the large LED screen. The life of the large screen is reflected by the attenuation of the LED, that is, the LED will decrease over time until it disappears. High temperature is the main reason for the light attenuation of LED large screens, and it will shorten the life of LED large screens. Different brands of LED large screens have different attenuations.
