LED display module and electronic device

Abstract

An LED display module and an electronic device, the LED display module comprising a shell, a power supply substrate, an LED light-emitting unit, a heating module and a temperature measurement module; the power supply substrate comprising a first region and a second region which are independent of each other; the LED light-emitting unit being arranged in an array on the power supply substrate; the heating module being arranged on the power supply substrate and located in the first region; the temperature measurement module being connected with the heating module, and the temperature measurement module being configured to control the heating module to heat when the temperature of the first region is lower than the temperature of the second region. When the first region and the second region have a temperature difference, the temperature measurement module can control the heating module to heat, so as to reduce the temperature difference on the power supply substrate, avoid the temperature difference of the power supply substrate affecting the light-emitting effect of the corresponding LED light-emitting unit, and finally improve the display effect of the LED display module.
