AI Technical Summary

Technical Problem

The large-angle light emission between adjacent light-emitting devices in existing light-emitting modules leads to a decrease in display effect and high power consumption, which affects the battery life of electronic devices.

Method used

The design employs a reflective structure, which is located on one side of the drive backplate, forming an accommodating opening. The side and bottom surfaces of the reflective structure form an acute angle, which is used to reflect the large-angle light emitted by the light-emitting device to the light-emitting surface. Combined with a heat-conducting part and a protective layer, it can improve the light extraction efficiency and reduce power consumption.

Benefits of technology

It significantly improves the light extraction efficiency of light-emitting devices, reduces the power consumption of light-emitting modules, extends service life, and enhances the market competitiveness of display devices.

Abstract

The application provides a light-emitting module and a display device. The light-emitting module comprises a driving backboard, a reflecting structure and a light-emitting device. The reflecting structure is located on one side of the driving backboard and encloses a receiving opening on the driving backboard. The light-emitting device is located in the receiving opening and is bonded to the driving backboard. The reflecting structure comprises a side surface facing the corresponding light-emitting device and a bottom surface facing the driving backboard. The included angle between the side surface and the bottom surface is an acute angle. The distance between the side of the reflecting structure away from the driving backboard and the driving backboard is greater than the distance between the side of the light-emitting device away from the driving backboard and the driving backboard. The side surface is used to reflect the light generated by the light-emitting device and incident on the reflecting structure towards the light-emitting surface direction of the light-emitting device. In this way, the reflecting structure in the above structure can block the large-angle light emission of the light-emitting device in a larger range and reflect it towards the light-emitting surface of the light-emitting device, thereby significantly improving the light-emitting efficiency of the light-emitting device and reducing the power consumption of the light-emitting module.
