Problems solved by technology

[0004] However, due to the large spacing between multiple LEDs in the LED light bar, limited by the light-emitting angle of the LEDs, the bright area in front of the LED and the dark area between the LEDs appear alternately bright and dark, resulting in a Hot-spot (hot spot) defect; in addition, Since the op

Abstract

The invention aims at providing a back plate structure, a backlight module, a display device, and a manufacturing method of the back plate structure, wherein the back plate structure comprises a bottom surface plate and four side surface plates located at the periphery of the bottom surface plate, the edge of one reserved side surface plate of the four side surface plates is bent and extends towards the center of the bottom surface plate to form a bending part, the bending part comprises an inner surface, one surface of the inner surface faces the bottom surface plate, a reflection layer is arranged on the inner surface of the bending part, and a light scattering layer is also arranged on the reflection layer. According to the back plate structure, the backlight module, the display device, and the manufacturing method of the back plate structure, the Hot-spot phenomenon of the backlight module is improved, and the display quality of the display device is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backplane structure, a backlight module, a display device and a manufacturing method of the backplane structure. Background technique [0002] With the continuous development of display technology, liquid crystal display devices have been widely used in electronic products such as smart phones, tablet computers, notebooks, monitors, and televisions. However, since the liquid crystal panel itself does not have the function of emitting light, it is usually necessary to use a backlight as a light source to realize the display function. The backlight usually includes a backplane, a light guide plate arranged in the backplane, an LED light bar arranged on the light-incoming side of the light guide plate, an optical film arranged on the light-emitting surface of the light guide plate, and a reflective sheet arranged on the bottom surface of the light guide plate. And the plastic fr...
