[0035] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0036] First, the relevant technologies involved in this application will be explained:

[0037] For portable display devices with communication functions, due to the size limitations of the display device, in order to ensure the thinness and lightness of the display device, the distance between communication devices, such as antennas, and the display module is relatively close. This causes communication signals to interfere with the signal traces in the display module. In particular, the bending areas of the display module with a large number of traces are more susceptible to communication signal interference, which in turn leads to display problems.

[0038] In particular, with the application of 5G (Generation) communication technology, the frequency of its antennas has increased significantly. For portable display devices using 5G communication technology, the number of antennas will also increase significantly, making them more susceptible to display problems due to interference from communication signals.

[0039] The display module and display device provided in this application are intended to address the above-mentioned technical problems in the prior art.

[0040] The technical solution of this application and how it solves the above-mentioned technical problems are described in detail below with specific embodiments. It should be noted that the following embodiments can be referenced, borrowed, or combined with each other, and the same terms, similar features, and similar implementation steps in different embodiments will not be described again.

[0041] This application provides a display module, the structural schematic diagram of which is shown below. Figure 1 As shown, it includes: a light-transmitting cover plate 10, a display panel 20, and a signal shielding component 30.

[0042] The display panel 20 and the signal shield 30 are both disposed on one side of the light-transmitting cover plate 10; the display panel 20 includes a display area and a bending area 21 located outside the display area; the signal shield 30 includes a shielding part 31, and at least part of the bending area 21 is covered by the shielding part 31.

[0043] In the display module provided in this application embodiment, by providing a signal shielding member 30 including a shielding part 31, and covering at least a portion of the bending area 21 of the display panel 20 with the shielding part 31, the interference of external signals on the signal traces located in the bending area 21 can be reduced, especially the interference of external communication signals on the signal traces can be reduced, the stability of the signal transmission of the signal traces can be ensured, the probability of display failure of the display panel 20 can be reduced, and the display effect of the display panel 20 can be guaranteed.

[0044] In the embodiments of this application, such as Figure 1 As shown, due to the obstruction of the signal shield 30, Figure 1 The bending area 21 of the display panel 20 is not visible in the image. Please refer to [reference needed] for details about the bending area 21 of the display panel 20. Figures 2-4 ,like Figures 2-4 The bending area 21 in the display panel 20 includes a bonding area for bonding with the flexible circuit board 40. Therefore, there are a large number of wires for transmitting signals in the bending area 21. Under the influence of external communication signals, the wires are prone to generate current due to electromagnetic induction, which affects the signal transmitted by the wires themselves, causing the display panel 20 to fail to display the picture normally and resulting in a problem of poor display.

[0045] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, both the display panel 20 and the signal shield 30 are disposed on one side of the light-transmitting cover 10, and the other side of the light-transmitting cover 10 is the display surface of the display module.

[0055] In this application, by setting the first sub-board portion 311 to face at least part of the bending area 21 on the side and the second sub-board portion 312 to face at least part of the bending area 21 on the top, the influence of external communication signals on the bending area 21 can be further reduced, the stability of the signal transmission of the wires in the bending area 21 can be ensured, thereby reducing the probability of display failure of the display panel 20 and ensuring the display effect of the display panel 20.
