[0081] In order to make the objects, technical solutions and advantages of the present disclosure clearer, below the embodiments of the present disclosure will be described in detail with reference to the drawings. Note that the embodiments can be implemented in a plurality of different forms. Those skilled in the art can easily understand that the manner and content can be changed into various forms without departing from the spirit and scope of the present disclosure. Therefore, the present disclosure should not be interpreted as being limited to the content described in the following embodiments. The embodiments in the present disclosure and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0082] The scale of the drawings in the present disclosure can be used as a reference in the actual process, but is not limited thereto. For example, the width-length ratio of the channel, the thickness and spacing of each film layer, and the width and spacing of each signal line can be adjusted as needed. The number of pixels in the display panel and the number of sub-pixels in each pixel are also not limited to the number shown in the drawings. The drawings described in the present disclosure are only schematic diagrams, and one embodiment of the present disclosure is not limited to the shapes or values shown in the drawings.

[0083] In the present specification, ordinal terms such as "first", "second", and "third" are used to avoid confusion among components, and are not intended to be limiting in number.

[0084] In the present specification, in order to facilitate the description, words indicating the orientation or positional relationship such as "middle", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like are used to describe the positional relationship of the components with reference to the drawings, and are only for the convenience of the description and simplification of the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present disclosure. The positional relationship of the components is appropriately changed according to the direction of describing each component. Therefore, it is not limited to the words described in the specification, and can be appropriately changed according to the situation.

[0085] In the present specification, unless explicitly specified and limited, the terms "mount", "connect", and "connect" should be broadly understood. For example, it can be fixedly connected, or detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate, or the communication between two elements. The specific meaning of the above terms in the present disclosure can be understood by those skilled in the art according to the specific circumstances.

[0086] In the present specification, "electrically connected" includes the case where the components are connected together through an element having a certain electrical effect. The "element having a certain electrical effect" is not particularly limited as long as it can perform the transmission of electrical signals between the connected components. Examples of the "element having a certain electrical effect" include not only electrodes and wiring, but also switching elements such as transistors, resistors, inductors, capacitors, other elements having various functions, and the like.

[0087] In the present specification, "parallel" means that the angle formed by two straight lines is -10° or more and 10° or less, and therefore also includes a state in which the angle is -5° or more and 5° or less. In addition, "perpendicular" means that the angle formed by two straight lines is 80° or more and 100° or less, and therefore also includes a state in which the angle is 85° or more and 95° or less.

[0088] In this specification, "film" and "layer" can be replaced with each other. For example, "conductive layer" can be replaced with "conductive film" at times. Similarly, "insulating film" can be replaced with "insulating layer" at times.

[0089] In this specification, a triangle, a rectangle, a trapezoid, a pentagon, or a hexagon is not necessarily a strict one, and can be an approximate triangle, rectangle, trapezoid, pentagon, or hexagon. There can be some small deformation due to a tolerance. There can be an obtuse angle, an arc side, and deformation. In this disclosure, "about" means that a limit is not strictly defined, and a value within a range of process and measurement errors is allowed.

[0090] As shown in FIG. 1, Figure 1 FIG. 1 is a schematic view of a display module according to an embodiment of the present disclosure, Figure 2 FIG. 2 is a schematic view of a mounting plate according to an embodiment of the present disclosure, Figure 1 As shown in FIG. 2, Figure 1 and Figure 2 The display module of the present example can include a display panel 1, a housing 2, a backlight 3, a control board 4, and a mounting plate 5.
