Abstract

The invention discloses a display module and a display device, and relates to the technical field of display. The display module comprises a display panel; a backlight module which is positioned on one side far away from the light emitting surface of the display panel; a lower polaroid which is positioned between the display panel and the backlight module; a through hole which penetrates through the lower polaroid and the backlight module in the direction perpendicular to the light emitting surface of the display panel; and a polarization conversion device which is arranged in the through hole, wherein at least part of light emitted by the light source of the backlight module enters the through hole through the polarization conversion device and is transmitted to the display panel. The polarization conversion device is used for changing the polarization state of light emitted by the light source. According to the invention, the polarization conversion device is introduced into the display module, at least part of light emitted by the light source of the backlight module can be converted into linearly polarized light from circularly polarized light, and the linearly polarized lightis transmitted to the display panel through the through hole so that the problem that a display picture in the area becomes white after the circularly polarized light is emitted to the display panel is solved, and the display effect of the display panel is greatly improved.

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] With the development of display technology, display panels have higher and higher screen-to-body ratios, and full-screen displays have received widespread attention due to their narrow-frame or even frame-less display effects. At present, the front of display devices such as mobile phones and tablet computers often needs to reserve space for photosensitive elements such as front cameras, infrared sensing devices, and fingerprint recognition devices. For example, the front camera can be set at the top of the display area, and the corresponding position The formed camera area can take pictures when the front camera is turned on, and display the picture when the front camera is turned off, thereby increasing the screen-to-body ratio of the device. [0003] In the prior art, in order to form the l...
