Title:
LIGHT-EMITTING MODULE AND PREPARATION METHOD THEREFOR, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/000548
Kind Code:
A1
Abstract:
A light-emitting module. The light-emitting module comprises a bearing substrate (10), a first light-emitting circuit layer (20), a back plate (40), a mounting cavity (60), and a connecting member (50). The first light-emitting circuit layer (20) is stacked on the bearing substrate (10). The back plate (40) is stacked on the side of the bearing substrate (10) away from the first light-emitting circuit layer (20) and is in contact with the bearing substrate (10). The mounting cavity (60) is arranged on at least one among the back plate (40) and the bearing substrate (10), and an inner wall of the mounting cavity (60) is jointly enclosed and formed by the back plate (40) and the bearing substrate (10). The connecting member (50) is disposed in the mounting cavity (60) and fixedly connects the bearing substrate (10) to the back plate (40). The connecting member (50) is located in the mounting cavity (60) and fixedly connects the back plate (40) to the bearing substrate (10), so that the back plate (40) is in direct contact with the bearing substrate (10), thus the transmission path for heat generated by the first light-emitting circuit layer (20) is the bearing substrate (10) and the back plate (40), and finally the first light-emitting circuit layer (20) can exchange heat with external air, thereby achieving effective heat dissipation. In addition, the mounting cavity (60) is located inside of the edge contour of the bearing substrate (10) and the back plate (40), so that the structure after the bearing substrate (10) is connected to the back plate (40) is more compact.
