Abstract: A backlight module. Heat sinks fill gaps between the light sources and the reflective sheet, which greatly improves the heat dissipation efficiency. Current backlight module has no space for a heat sink due to the limitation of the structure space. The invention provides a heat dissipation performance of the backlight module by optimizing to find a relatively unique position to place the heat dissipation material. The invention can effectively and quickly dissipate heat of a light emitting diode (LED) lamp to avoid problems such as reliability analysis (RA) test fluctuations.

Abstract: A backlight module, display device, and a manufacturing method of a backlight module are provided. The backlight module includes a back plate, a reflective sheet, a light guide plate, an optical diaphragm set, and a sleeve. A perforation is disposed on the backlight module, and the perforation sequentially penetrates through the back plate, the reflective sheet, the light guide plate, and the optical diaphragm set. The sleeve is sleeved in the perforation. The sleeve is hollow, and a sleeve side wall encircles to form a backlight hole. The display device includes the backlight module, a display panel, and a light shielding adhesive between them. The manufacturing method of a backlight module includes steps: providing a back plate, manufacturing a reflective sheet, manufacturing a light guide plate, manufacturing an optical diaphragm set to form a perforation, and manufacturing a sleeve sleeved in the perforation.

Abstract: A backlight module includes a backboard, a light guide plate arranged on the backboard, an optical film arranged on the light guide plate, a frame fixed with the backboard and configured to fix the light guide plate and the optical film, and an inclined block arranged on an upper surface of the frame. A slant of the inclined block is smoothly connected to the upper surface of the frame. A liquid crystal display having the backlight module is also provided. The backlight module and the LCD including the backlight module supply the glue with wide and broad attaching space. It brings great convenience to processing and assembly of the glue, thereby saving time and costs.

Abstract: A display module and a glue dispensing method thereof are provided. The display module includes a display panel and a backlight module, and a polarizer is disposed between the display panel and the backlight module. The display module includes a blind hole for under-screen camera lighting in a display area, and the display panel includes a light transmission region and a light non-transmission region which are disposed corresponding to the blind hole. An aperture of the polarizer corresponding to the blind hole is reduced and blackened at an edge, thereby omitting the first glue dispensing process in the blind hole of the conventional structures.

Abstract: A slim bezel backlight module and a liquid crystal display apparatus having the same are disclosed. The backlight module includes a light source, a light guide plate, a reflector, a plastic frame assembly and a square-shaped adhesive tape. The plastic frame assembly is designed to be integrated by iron material and plastic material, and a few plastic portions of the plastic frame assembly protruded from the sides of the plastic frame assembly to form a zigzagged surface for increasing the adhesion area for the square-shaped adhesive tape, thereby solving the problem that the lack of enough border width makes the plastic frame assembly hard to be processed and assembled.
