Problems solved by technology

[0003] Common display devices in daily life, such as touch-sensitive mobile phones, are prone to fall to the ground or similar collision damage because people often carry them with them.
At this time, the light source and the light guide plate in the backlight module will be misaligned to form a gap. Once the gap is too large, the light guide plate will not be able to effectively guide the light emitted by the light source, thereby affecting the display function of the display device.

Abstract

A backlight module includes a light source, a frame and a light guide module. The frame includes a light-emitting side frame with the light source, a first side frame, a second side frame and a third side frame. The first side frame is vertical to the light-emitting side frame. The second side frame is opposite to the first side frame. Both first side frame and second side frame have at least one L-shaped groove. The third side frame is opposite to the light-emitting side frame and has at least one positioning splinter. The light guide module is surrounded by the frame and has a light guide plate. The light guide plate has a plurality of positioning convex portions at its two edges. The positioning convex portions are respectively coupled to the L-shaped grooves. The positioning splinters keep the light guide plate adjacent to the light source by direct connecting.

Description

technical field [0001] The present disclosure relates to a backlight module. Background technique [0002] With the advancement of technology, various display devices appear in every corner of people's life. An important part of the display device is the backlight module, which is related to the light and dark performance of the overall screen when the display device displays information on its screen. [0003] Common display devices in daily life, such as touch-sensitive mobile phones, for example, are prone to fall to the ground or similar collision damage because people often carry them with them. At this time, the light source and the light guide plate in the backlight module will be misaligned to form a gap. Once the gap is too large, the light guide plate will not be able to effectively guide the light emitted by the light source, thereby affecting the display function of the display device. As for the dislocations caused by collision and falling, the dislocation dir...
