[0026] Organic light-emitting diode (OLED) and flat panel display devices based on light-emitting diode (LED) technologies are widely used in various consumer electronics products such as mobile phones, televisions, laptops, and desktop computers due to their advantages such as high image quality, energy saving, thin body and wide range of applications, becoming the mainstream of display devices.

[0027] Cover plates and ink are indispensable components of display devices. Ink is used around the cover plate to shield the traces and bezels of the display screen, improving the visual effect. However, existing display devices have chamfered edges on their cover plates, which can cause light leakage when printing ink on the cover plate. Furthermore, printing ink on the chamfered edges is more difficult, and the ink can easily peel off or print in other areas of the cover plate, affecting the assembly of the display device. For example, light can reflect off the ink edges, creating a bright line around the edge of the display device, which seriously affects product performance evaluation and market competitiveness.

[0028] In view of this, embodiments of this application provide a display module, a display device, and a display apparatus. The display module includes a cover plate body, a light-shielding layer, and a display panel. The cover plate body includes a first surface, a second surface, and a third surface. The first and second surfaces are planar, arranged opposite to each other, with the first surface parallel to the second surface.

The orthographic projection of the second surface onto the first surface lies within the first surface, and the orthographic projections of the second and third surfaces onto the first surface coincide with the first surface. The light-shielding layer is located on the third surface. The display panel is located on the side of the second surface facing away from the first surface, and the orthographic projection of the display panel onto the first surface lies within the orthographic projection of the second surface onto the first surface. By setting the third surface of the cover plate body as a curved surface and the light-shielding layer located on the third surface, the above embodiments avoid the situation where the light-shielding layer falls off or fails to cover the sides of the cover plate body due to the chamfered structure, thereby preventing light leakage from the display module.

[0089] The display device 300 provided according to any embodiment of this application belongs to the same inventive concept as the display module 100 or display device 200 provided in the embodiments of this application, and has corresponding film layer structures and beneficial effects. Details not described in detail in the embodiments of the display device 300 can be found in the embodiments of the display module 100 or display device 200, and will not be repeated here.

[0090] This application provides a display module, display device, and display equipment. The display module includes a cover plate body, a light-shielding layer, and a display panel. The cover plate body includes a first surface, a second surface, and a third surface. The first and second surfaces are planar, opposite to each other, and the first surface is parallel to the second surface. The third surface is curved, connecting the first and second surfaces and surrounding the second surface. The orthographic projection of the second surface onto the first surface lies within the first surface, and the orthographic projections of the second and third surfaces onto the first surface coincide with the first surface. The light-shielding layer is located on the third surface. The display panel is located on the side of the second surface facing away from the first surface, and the orthographic projection of the display panel onto the first surface lies within the orthographic projection of the second surface onto the first surface. By setting the third surface of the cover plate body to be curved and the light-shielding layer located on the third surface, the above embodiment avoids the situation where the light-shielding layer falls off or fails to cover the sides of the cover plate body due to the chamfered structure, thereby preventing light leakage from the display module.

[0091] Furthermore, the display device includes the aforementioned display module and mid-frame, with the mid-frame and cover plate body enclosing an accommodating space, and the display panel located within the accommodating space. The above embodiment improves the display effect by setting the third surface of the cover plate body to a curved surface, thus avoiding gaps between the cover plate and the mid-frame.
