Backlight module and display device

Abstract

The invention provides a backlight module and a display device. The backlight module comprises a substrate, a plurality of light-emitting units, a light guide layer and a light reflecting layer. The design of the ultrathin flexible backlight module is achieved, and it is guaranteed that the overall thickness of the backlight module does not exceed 0.3 mm; a direct type light emitting mode is adopted, it is guaranteed that backlight has good visual angle uniformity when bent at different angles, no uniform light film structure exists in the backlight module, a net point structure is manufactured on the surface film surface of the lamp panel, light emitting uniformity at different positions of the front face is achieved through the combined action of the optical waveguide and the net point structure, the thinning of backlight and the light emitting uniformity of the whole surface are guaranteed, the light emitting uniformity and the bending characteristic of the backlight are considered, the light emitting uniformity of the whole surface is achieved, meanwhile, the overall lighting effect of the lamp panel can be improved, and the ultrathin flexible backlight with the higher lighting effect is achieved.

Description

technical field [0001] The invention relates to the display field, in particular to a backlight module and a display device. Background technique [0002] Flexible screen has the technical advantages of being bendable and flexible, so it is favored by many display terminal manufacturers including mobile phones and notebooks. OLED display technology can use flexible substrates as substrates, and has technical advantages over LCDs in the preparation of flexible devices. Conventional LCDs cannot compete with OLEDs in flexibility due to glass substrates, backlights and other factors. [0003] But at present, there are exhibits or reports on LCD flexible display screens, but LCD backlight modules are temporarily unable to achieve a large degree of bending or flexibility due to factors such as plastic iron frames and light guide plates. Flexible LCD backlight modules have become a development trend. The bottleneck of flexible LCD development. Moreover, the thickness of the LCD b...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a backlight module and a display device, which solves the problem that the LCD backlight module cannot be bent or flexed to a large extent temporarily due to factors such as rubber iron frame and light guide plate, and the flexible LCD backlight module has become a The bottleneck in the development of flexible LCDs, and the thickness of the LCD backlight is large, which is difficult to meet the technical problems of ultra-thin backlight modules
