The display module, the display panel, the display screen, and the electronic device provided by the embodiments of the present application are specifically described below.

Referring to FIGS. 1 to 8 , one aspect of an embodiment of the present application provides a display module. The display module 10 includes an electrical function layer 11 , and the electrical function layer 11 includes a plurality of sublayers 111 stacked in sequence along a first direction, a plurality of Electrical traces 112 disposed on any one of the sub-layers 111, and a plurality of dummy structures 113 electrically isolated from the electrical traces 112, the dummy structures 113 are disposed on one or more of the sub-layers 111; in a plane perpendicular to the first direction For the projection surface, the projection of the dummy structure 113 on the projection surface at least covers the gap between the projections of the two adjacent electrical traces 112 on the projection surface.

In this embodiment of the present application, a plane perpendicular to the first direction is used as the projection surface, and the gap between the projections of two adjacent electrical traces 112 on the projection surface can be determined by two adjacent electrical traces on the same sublayer 111 . The electrical traces 112 are formed, and may also be formed by two adjacent electrical traces 112 on different sublayers 111 ; exemplarily, in an embodiment, the above-mentioned gap may be two adjacent ones on the same sublayer 111 . The gap between the electrical traces 112, and along the first direction, there is no electrical trace 112 on other sub-layers 111 covering at least the gap between the above-mentioned electrical traces 112; in another embodiment, the above-mentioned gaps may be different The gap between two adjacent electrical wirings 112 on the sublayer 111, and along the first direction, there is no electrical wiring 112 on other sublayers 111 covering at least the gap between the electrical wirings 112; so , a plane perpendicular to the first direction is used as the projection plane, and there is a gap between the projections of two adjacent electrical traces 112 . The dummy structure 113, that is, the dummy structure, refers to a structure that has no logical and functional role. On the one hand, the electrical wiring is used to realize the electrical connection function between electronic components. Since the dummy structure has no logical and functional functions, the dummy structure 113 and the electrical wiring 112 are electrically isolated, that is, the dummy structure 113 and the electrical wiring 112 are not Therefore, the dummy structure 113 will not affect the function of the electrical wiring 112. When designing and manufacturing the electrical functional layer 11, the user can easily design and manufacture it according to the actual needs. When there is a gap therebetween, the dummy structure 113 is used to cover the gap, and when the incident light passes through the electrical functional layer 11, the gap between the projections of the adjacent two electrical traces 112 is prevented from becoming a diffraction slit, thereby avoiding phase diffraction. The gap between the projections of the two adjacent electrical traces 112 causes diffraction; on the other hand, since the dummy structure 113 is a figure without logic and function, one or more sublayers corresponding to the area where the dummy structure 113 needs to be set can be arranged 111, the setting position is flexible and convenient, and the shape of the dummy structure 113 can be flexibly changed according to the requirements (refer to FIG. 1 to FIG. 8), only the projection of the dummy structure 113 needs to cover at least the projection of the adjacent two electrical traces 112 The gap between them is sufficient. In this way, the design and manufacturing process is less difficult and the cost is lower.

Specifically, the display module can transmit light, the electrical wiring 112 can transmit light, and the dummy structure 113 can transmit light.

It can be understood that, in an embodiment, a gap exists between two adjacent electrical wirings 112 on the same sublayer 111. For example, two adjacent electrical wirings 112 on the same sublayer 111 are respectively defined as K1 and K2, and the electrical traces 112 located on the sub-layer 111 below them can at least cover the gap between the two adjacent electrical traces 112 on the same sub-layer 111, for example, located on the sub-layer 111 below them The electrical trace 112 is defined as K3, that is to say, K3 can cover at least the gap between K1 and K2, then the gap between K1 and K2 is covered by K3, taking the plane perpendicular to the first direction as the projection plane, the phase There is no gap between the projection of the adjacent K1 on the projection surface and the projection of K3 on the projection surface, and there is no gap between the projection of the adjacent K2 on the projection surface and the projection of K3 on the projection surface.
