Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to an LED display module and a preparation method and application thereof. Background technique [0002] When the LED display module is working, the electrical energy cannot be completely converted into light energy, and the electro-optical conversion efficiency is 20% to 30%, and about 70% of the electrical energy is converted into heat energy, which causes the LED display module to generate heat during operation. As the temperature of the LED display module increases, the LED light emission wavelength will drift, which affects the display effect of the LED display module; at the same time, the temperature of the LED display module is too high, which will also reduce the life of the LED lamp beads. Therefore, improving the heat dissipation capability of the LED display module is an important research content in the field of LED display. [0003] The existing...
