Backlight module and display device

Abstract

The invention discloses a backlight module and a display device and aims to solve the technical problem of larger boundary width of a hole digging area in the prior art. The backlight module is provided with a through hole, wherein the through hole penetrates through a light guide plate and a film material; an iron frame comprises an iron frame body and a tubular structure located in the through hole, and the iron frame body extends along the inner wall of the through hole to form the tubular structure. According to the technical scheme, on one hand, light rays inside and outside the digging area can be obstructed by the tubular structure, on the other hand, the tubular structure can realize the function of fixing elements in the hole during using of a plastic frame, so that the boundary width of the digging area is not limited by the width of the plastic frame, and the technical effect of reducing the boundary width of the digging area is realized.

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] With the development of display technology, full-screen technology has emerged, and this type of technology is widely used in various electronic devices such as mobile phones. Such mobile phones using the full-screen technology are called full-screen mobile phones. [0003] In a full-screen mobile phone, it is usually necessary to place a camera in the effective display area of ​​the mobile phone, so correspondingly, it is necessary to dig holes in the corresponding effective display area when designing the liquid crystal display module of the mobile phone. [0004] At present, the solutions for digging holes in the effective display area of ​​the liquid crystal display module usually include digging holes for both the liquid crystal panel and the backlight module, or only digging through the backlight module...

AI Technical Summary

Problems solved by technology

However, the width of the plastic frame can only be reduced to 0.9mm at most. This is because if the width of the plastic frame is less than 0.9mm, on the one hand, the indirect bonding plastic frame in the backlight module will be bonded to the light-shielding tape on the lower polarizer. Insufficient, on the other hand, the edge of the film material is too close to the effective display area, resulting in light leakage in the digging hole and light leakage at the edge of the effective display area
