Problems solved by technology

[0004] Usually the sum of the thickness of the array substrate and the color filter substrate in the display panel is not less than 300 μm, and the surface of the substrate is smooth. When the backlight light source passes through the display panel from the light guide plate, the light is easily reflected on the upper and lower surfaces of the TFT substrate and the CF substrate. Part of the light enters the photosensitive device, causing the problem that the dark state in the imaging is not dark enough. In addition, because the photosensitive device is sensitive to light, it is easy to affect its corresponding acquisition performance
[0005] It can be seen that the existing display module has the technical problem that light is easy to leak

Abstract

The invention discloses a display module and a display device, and relates to the technical field of display. The display module comprises a cover plate; a display panel, a backlight unit and a metalsleeve, wherein the display panel is arranged on one side of the cover plate; the display panel comprises a hollow part, a first non-display area, display area and the second non-display area; the first non-display area surrounds the hollow part; the display area surrounds the first non-display area; the second non-display area surrounds the display area; the backlight unit is arranged on one side, far away from the cover plate, of the display panel; the backlight unit comprises a backlight hole which corresponds to the hollow part and penetrates through the backlight unit in the thickness direction of the backlight unit; the backlight unit further comprises an iron frame, wherein the iron frame comprises a main body part corresponding to the display area and a first bent part arranged around the inner side wall of the backlight hole; and the metal sleeve is arranged between the first bent part and the cover plate and is arranged around the inner side wall of the backlight hole. Therefore, the first bent part and the metal sleeve are arranged on the inner side wall of the backlight hole, so that the display module is beneficial for improving the light leakage problem in the corresponding positions of the backlight hole and the hollowed part.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display module and a display device. Background technique [0002] At present, display devices such as mobile phones and tablet computers often need to reserve space for electronic photosensitive devices such as commonly used front cameras, infrared sensing devices, and fingerprint recognition devices. For example, these photosensitive devices are arranged at the top of the front of the display device, and the corresponding position forms a non-display area, thereby reducing the screen-to-body ratio of the device. [0003] In the prior art, in order to increase the screen-to-body ratio, a high light transmission area can be set up in the display area of ​​the display panel to accommodate the above-mentioned photosensitive device, wherein the high light transmission area can be a channel through which the display panel and the backlight unit are dug through. T...
