Backlight module and display device

Abstract

The invention discloses a backlight module and a display device, comprising a reflective sheet, a light guide plate, a light guide layer and a reverse prism light guide film which are sequentially stacked; at least one side of the light guide layer is provided with an anti-reflection layer. The backlight module and the display device proposed by the present invention can solve the problem of the light guide plate being scratched to a certain extent.

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] Due to the high light efficiency of the reverse prism backlight structure, it can control the angle of light to concentrate in the forward direction, thereby significantly improving the brightness of the backlight. The backlight structure is very suitable for saving backlight power consumption and reducing the overall power consumption of electronic equipment. At the same time, the reverse prism backlight structure uses less optical film materials, and can also avoid problems such as film material wrinkles to a certain extent, so it has a wide range of market applications. sex. [0003] However, in the actual application of the reverse prism backlight structure in small and medium-sized display screens, there are still problems of immature technology and low mass production yield. One of the most serious pr...

AI Technical Summary

Problems solved by technology

This is because the pyramidal structure of the reverse prism film faces the light guide plate (LGP) side, and the apex angle of the pyramidal structure is relatively sharp, which is very easy to scratch the LGP; , polycarbonate (PC) material is mostly used, so its surface hardness is low, which increases the risk of being scratched and adsorbed
