Detailed Description

In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the various exemplary embodiments. It may be evident, however, that the various exemplary embodiments may be practiced without these specific details or with one or more equivalent arrangements. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the various exemplary embodiments. Furthermore, the various exemplary embodiments may be different, but are not necessarily exclusive. For example, the specific shape, configuration, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

In the drawings, the size and relative sizes of elements may be exaggerated for clarity and/or description. As such, the dimensions and relative dimensions of the various elements are not necessarily limited to those shown in the figures. While the exemplary embodiments may be practiced differently, the specific process sequence may be performed differently than as described. For example, two consecutively described processes may be performed substantially simultaneously or in reverse order of the order described. Furthermore, like reference numerals denote like elements.

When an element is referred to as being "on," "connected to," or "coupled to" another element, it can be directly on, connected or coupled to the other element or intervening elements may be present. In contrast, when an element is referred to as being "directly on," "directly connected to," or "directly coupled to" another element, there are no intervening elements present. Other terms and/or expressions used to describe the relationship between elements should be interpreted in a similar manner, e.g. "between" and "directly between", "adjacent" and "directly adjacent" or "in" and "directly on" etc. Furthermore, the term "connected" may refer to a physical connection, an electrical connection, a communication connection, and/or a fluid connection. Further, the X-axis, Y-axis, and Z-axis are not limited to three axes of a rectangular coordinate system, and can be interpreted in a broader sense. For example, the X-axis, Y-axis, and Z-axis may be perpendicular to each other, or may represent different directions that are not perpendicular to each other. For the purposes of this disclosure, "at least one of X, Y and Z" and "at least one selected from the group consisting of X, Y and Z" may be interpreted as X only, Y only, Z only, or any combination of two or more of X, Y and Z such as XYZ, XY, YZ and XZ. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of example embodiments.

12. The display module according to claim 11, wherein a third gear is provided on a side of the first supporting shell close to the supporting plate, a third rack guide extending along the first direction is provided on a side of the supporting plate close to the first supporting shell, and the third gear is engaged with the third rack guide.

13 . The display module according to claim 12 , wherein the curling mechanism further comprises a second control system configured to drive the third gear to rotate.

14 . The display module according to claim 11 , wherein the curling mechanism further comprises a spring telescopic rod extending along the first direction, and the rotating shaft is connected to the support plate via the spring telescopic rod.

15. The display module according to claim 14, wherein the rotating member comprises at least two rotating posts, and the at least two rotating posts are spaced apart along the axial direction of the rotating shaft; and

One end of the spring telescopic rod is connected to a portion of the rotating shaft exposed by the spacing area between two adjacent rotating columns, and the other end of the spring telescopic rod is connected to the support plate.

16 . The display module according to claim 1 , further comprising a pressure sensing module, wherein the pressure sensing module is disposed on a side of the second planar display portion facing away from the light emitting surface.

17. The display module according to any one of claims 11 to 13 and 15, wherein the display module further comprises a supporting back plate, wherein the supporting back plate is arranged on a side of the display panel away from the light emitting surface;

Wherein, the supporting back plate comprises a first hollow pattern, the orthographic projection of the first hollow pattern on the display panel at least partially overlaps with the area where the bendable display portion is located, and/or

The supporting back plate includes a second hollow pattern, and the orthographic projection of the second hollow pattern on the display panel at least partially overlaps with the area where the rollable display portion is located.

18. The display module according to claim 17, wherein the first hollow pattern comprises a plurality of first hollow portions arranged at intervals, the second hollow pattern comprises a plurality of second hollow portions arranged at intervals, and a distribution density of the plurality of first hollow portions is less than a distribution density of the plurality of second hollow portions.

19. A method for controlling a display module, wherein the method is applied to the display module according to any one of claims 1 to 18, the method comprising:

The host of the display module receives the bending instruction; and

The host controls the first sliding mechanism and the second sliding mechanism to slide in response to the bending instruction, so that the bending display portion bends, and the light-emitting surface of the first planar display portion and the light-emitting surface of the second planar display portion form a preset angle.

20. The control method of the display module according to claim 19, wherein the host of the display module receives the bending instruction comprises:
