Problems solved by technology
[0004] However, in the prior art, especially in the assembly process of the backlight module and the display panel of the full-screen liquid crystal display provided with the hole-digging area, in order to avoid the light leakage produced by the backlight module from causing damage to the components placed in the hole-digging area Affected, it is necessary to use a light-shielding tape to cover the edge of the hole-digging area. Generally, the light-shielding tape needs to be flush with or exceed the edge of the backlight, because the shrinkage of the light-shielding tape will cause problems such as insufficient adhesion of the light-shielding tape and light leakage in the digging hole. The design will cause the shape of the hole-digging area to be covered by the light-shielding tape, making it impossible to grasp the edge of the hole-digging position of the backlight module, and the combination accuracy cannot be guaranteed during assembly, which will affect the quality of the assembled display.

The invention discloses a display module and a display device, which belong to the field of display technology. The display module includes a backlight module and a display panel oppositely arranged; the backlight module includes a through hole, along a direction perpendicular to the light emitting surface of the display panel, The through hole runs through the backlight module; the light-shielding tape is located between the backlight module and the display panel; at least one locking portion is located on the inner wall of the through hole; the orthographic projection of the locking portion to the light-emitting surface of the display panel includes a first edge close to the through hole The orthographic projection of the light-shielding tape to the light-emitting surface of the display panel includes the second edge close to the through hole, and the orthographic projection of the inner wall to the light-emitting surface of the display panel is the third edge; in a direction parallel to the light-emitting surface of the display panel, the second edge is located at the second edge between the first edge and the third edge. The display device includes the above display module. The present invention can achieve a higher screen ratio and enhance the shading effect, and can also improve the assembly accuracy of the backlight module and the display panel.
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] Since entering the era of smart displays, consumers have become more and more demanding on visual effects. Among them, in order to pursue the ultimate display experience, various display manufacturers are committed to the research and development of ultra-narrow bezel display. How to minimize the bezel width of the display and increase the screen-to-body ratio of the product has become a hot research topic. . Today, the full screen complies with this demand, and major display manufacturers have launched their own full-screen smart display products. The reason is that in addition to the full screen looking cooler and more upscale, there is also a display panel with a full screen design that has a larger proportion of the display area and an ultra-narrow bezel than a normal display. , can grea...
