Backlight module and display device

Abstract

The invention discloses a backlight module. The backlight module comprises a backplane and a plurality of out-light units spliced in sequence and fixedly mounted on the backplane, the out-light unit comprises a light guide plate, a plurality of light sources and a flexible printed circuit board for loading the plurality of light sources, the light guide plate comprises an out-light surface and a mounting surface which are arranged relatively, and an in-light surface connected between the out-light surface and the mounting surface, a flexible printed circuit board is arranged adjacent to the in-light surface and used for making the light emitted from the plurality of light sources get into the light guide plate, the mounting surface is fixedly connected with the backplane, the backplane and the light guide plate are all flexible materials, the plurality of out-light units are used for lightening a display panel collectively to make the display panel emit light evenly. The backlight module emits light evenly. The invention further discloses a display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] Liquid Crystal Display (LCD), as a communication interface between people and information, is currently the mainstream display method. It has superior characteristics such as high space utilization, low power consumption, no radiation, and low electromagnetic interference, and is widely used in information communication tools such as TVs, mobile phones, and tablet computers. [0003] In recent years, liquid crystal displays have been impacted by Organic Light-Emitting Diode (OLED) displays, and curved display or even variable curved display has become a difficult problem to be overcome in the design of liquid crystal displays. Existing liquid crystal displays generally include a display panel and a backlight module arranged in layers, and the backlight module is used to provide a backlight source for the dis...

AI Technical Summary

Problems solved by technology

The direct-type backlight module is affected by the size of the secondary lens of the Light Emitting Diode (LED) and the light output angle, and it does not perform well in thinning, so it is difficult to bend to match the shape and light output requirements of the display panel.

Although the side-type backlight module is thinner than the direct-type backlight module, it uses a single light guide plate, and the curved light guide plate is difficult to achieve uniform light output from the entire light guide plate, especially in large-size backlight modules. The phenomenon is more serious
