Abstract

The invention discloses a display module and a display device, and relates to the technical field of display. The display module comprises a backlight module and a display panel; the backlight modulecomprises a light guide plate and a back plate located on the side, away from the display panel, of the light guide plate, a through hole penetrating through the back plate and the light guide plate is formed in the backlight module in the direction perpendicular to the display panel, and the through hole is used for arranging an optical sensing device. The backlight module further comprises a light guide film, and the light guide film is located on the side, close to the display panel, of the back plate. The vertical projection of the light guide film on the display panel covers the verticalprojection of the through hole on the display panel. The problems that in the prior art, due to the fact that the brightness of the display area where the under-screen optical sensing device is located is low, the display area where the display screen optical sensing device is located is different from other display areas in display, the display effect of the whole picture is affected, and a fullscreen cannot be truly achieved are solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display module and a display device using the display module. Background technique [0002] With the development of display technology, users have higher and higher requirements for display devices with infrared fingerprint recognition function and camera function, such as thickness and screen ratio. Display devices such as "fingerprint recognition under the screen" and "camera under the screen". The fingerprint recognition device and the camera device are arranged between the backlight module and the housing of the display device, occupying the space of the whole device in the thickness direction of the display device, resulting in a relatively thick overall thickness of the display device, which affects the usability of users who pursue ultra-thin display devices. Further, by digging holes in the backlight module to install the fingerprint identification device an...
