Problems solved by technology
However, the light-shielding layer cannot completely block the signal traces between the display area and the hole-digging area. In this way, the area where the signal traces are exposed and the area where no signal traces are provided reflect and / or absorb light from the outside differently. This will lead to uneven display and affect the display effect of the display panel

The invention discloses a display module and a display device. It includes a display area and a non-display area; the non-display area includes at least two high light-transmitting areas and a wiring area; it also includes: a display panel, a cover plate, a light-shielding layer, signal wiring and a visual compensation layer; wherein the light-shielding layer includes at least two A first hollow part; the first hollow part corresponds to the high light transmission area one by one; the vertical projection of the high light transmission area on the plane where the cover plate is located is located in the vertical projection of the first hollow part on the plane where the cover plate is located; wherein, the signal goes The part where the vertical projection of the line on the plane where the cover plate is located and the vertical projection of the light-shielding layer on the plane where the cover plate is located does not overlap is the first branch, and the vertical projection of the visual compensation layer on the plane where the cover plate is located and the vertical projection of the light-shielding layer on the plane where the cover plate is located The non-overlapping part of the vertical projections is the second division; the vertical projection of the light-shielding layer on the plane of the cover plate is located in the vertical projection of the first division on the plane of the cover plate and the vertical projection of the second division on the plane of the cover plate within the surrounding area.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display module and a display device. Background technique [0002] Display panels with a high screen-to-body ratio are becoming more and more popular among consumers. At present, in order to increase the screen ratio of the display panel, a hollow area is usually added in the display area of the display panel, and a camera module and the like are installed in this area. [0003] In order to prevent unnecessary light leakage from affecting the performance of the camera set in the hollow area, a shading layer is usually arranged on the cover plate to effectively block the light around the hollow area, so as to improve the camera quality of the camera module. However, the light-shielding layer cannot completely block the signal traces between the display area and the hole-digging area, so that the exposed signal trace area and the area without signal...
