Detailed Description
For purposes of making the objects, solutions and advantages of the present application clearer, the following detailed description of the present application will be made with reference to the accompanying drawings, and it should be noted that the first direction in the embodiments of the present application refers to a direction perpendicular to the plane of the display module, such as the direction shown in fig. 1, and the orientation or positional relationship in the description of the embodiments of the present application is only for convenience of describing the present application and simplifying the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation and operate, and should not be considered as limiting the embodiments of the present application, and all other embodiments obtained by a person having ordinary skill in the art without making creative efforts belong to the protection scope of the present application.
Referring to fig. 1 to 8, in one aspect, a display module is provided in an embodiment of the present disclosure, in which a display module 10 includes an electrical functional layer 11, the electrical functional layer 11 includes a plurality of sub-layers 111 sequentially stacked 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, and the dummy structures 113 are disposed on one or more of the sub-layers 111; with a plane perpendicular to the first direction as a projection plane, the projection of the dummy structure 113 on the projection plane covers at least a gap between the projections of two adjacent electrical traces 112 on the projection plane.
In the embodiment of the application, a plane perpendicular to the first direction is taken as a projection plane, and a gap between projections of two adjacent electrical traces 112 on the projection plane may be formed by two adjacent electrical traces 112 on the same sub-layer 111, or formed by two adjacent electrical traces 112 on different sub-layers 111; for example, in an embodiment, the gap may be a gap between two adjacent electrical traces 112 on the same sub-layer 111, and along the first direction, there is no electrical trace 112 on another sub-layer 111 at least covering the gap between the electrical traces 112; in another embodiment, the gap may be a gap between two adjacent electrical traces 112 on different sub-layers 111, and along the first direction, no electrical trace 112 on another sub-layer 111 at least covers the gap between the electrical traces 112; thus, a plane perpendicular to the first direction is used as a projection plane, and a gap exists between the projections of two adjacent electrical traces 112. Dummy structures 113, i.e., dummy structures, refer to structures that have no logical or functional role. On one hand, the electrical trace is used for realizing the electrical connection function between electronic components, the dummy structure has no logic and functional functions, and the dummy structure 113 is electrically isolated from the electrical trace 112, that is, the dummy structure 113 is not electrically connected with the electrical trace 112, so that the function of the electrical trace 112 is not affected by the dummy structure 113, when the electrical functional layer 11 is designed and manufactured, a user can conveniently design and manufacture according to actual requirements, under the condition that a gap exists between the projections of two adjacent electrical traces 112, the gap is covered by the dummy structure 113, when incident light penetrates through the electrical functional layer, the gap between the projections of two adjacent electrical traces 112 is prevented from becoming a diffraction slit, and thus the gap between the projections of two adjacent electrical traces 112 is prevented from causing diffraction; on the other hand, since the dummy structure 113 is a pattern without logic and functional functions, the dummy structure 113 can be disposed on one or more sub-layers 111 corresponding to an area where the dummy structure 113 needs to be disposed, the disposition position is flexible and convenient, the shape of the dummy structure 113 can be flexibly changed as required (see fig. 1 to 8), and only the projection of the dummy structure 113 at least covers the gap between the projections of the two adjacent electrical traces 112 is required, so that the design and manufacturing process is difficult and the cost is low.
Specifically, the display module can transmit light, the electrical trace 112 can transmit light, and the dummy structure 113 can transmit light. It is understood that, in an embodiment, there is a gap between two adjacent electrical traces 112 on the same sub-layer 111, for example, two adjacent electrical traces 112 on the same sub-layer 111 are respectively defined as K1 and K2, and the electrical trace 112 on the sub-layer 111 below the same sub-layer can at least cover the gap between two adjacent electrical traces 112 on the same sub-layer 111, for example, the electrical trace 112 on the sub-layer 111 below the same sub-layer is defined as K3, that is, K3 can at least cover the gap between K1 and K2, then the gap between K1 and K2 is covered by K3, a plane perpendicular to the first direction is taken as a projection plane, there is no gap between the projection of the adjacent K1 on the projection plane and the projection of K3 on the projection plane, there is no gap between the projection of the adjacent K2 on the projection plane and the projection of K3 on the projection plane, thus, there is no gap between the projection of K1 on the projection surface, the projection of K2 on the projection surface, and the projection of K3 on the projection surface.
In the embodiments of the present application, the plurality means two or more.
In one embodiment, referring to fig. 3, the width of the overlapping portion of the projection of the dummy structure 113 on the projection plane and the projection of the electrical trace 112 on the projection plane is between 0 μm and 0.1 μm. Illustratively, taking a plane perpendicular to the first direction as a projection plane, a width of an overlapping portion of a projection of the dummy structure 113 on the projection plane and a projection of the electrical trace 112 on the projection plane is W, where W is 0 μm, 0.01 μm, 0.02 μm, 0.03 μm, 0.05 μm, 0.07 μm, 0.08 μm, 0.09 μm, 0.095 μm, or 0.1 μm, and so on. Due to the design, the width of the overlapping part of the projection of the dummy structure 113 on the projection plane and the projection of the electric trace 112 on the projection plane is small, so that the phenomenon that the transmission of light is influenced due to the fact that the width of the overlapping part is too large and the area of the part of the incident light passing through the corresponding electric trace 112 and the part of the dummy structure 113 is too large is avoided.
Illustratively, in an embodiment, in the projection plane, the dummy structure 113 corresponds to two adjacent electrical traces 112 forming a gap, a projection of the dummy structure 113 extends along the gap between the projections of the two corresponding adjacent electrical traces 112, and the projection of the dummy structure 113 closes the gap between the projections of the two corresponding adjacent electrical traces 112, so that the width of the overlapping portion of the projection of the dummy structure 113 and the projection of the corresponding electrical trace 112 is 0 μm, that is, the projection of the dummy structure 113 just closes the gap between the projections of the two corresponding adjacent electrical traces 112.
In one embodiment, the light transmittance of the material of the dummy structure 113 is the same as the light transmittance of the material of the electrical trace 112. Light transmittance refers to the percentage of the luminous flux of a beam of light passing through a substance or object as compared to the flux of light incident upon it. The light transmittance of the material of the dummy structures 113 is the same as that of the material of the electrical traces 112, so as to ensure uniformity of the light transmittance of the display module 10 and further reduce the influence of the display module 10 on the light beam propagation.
In one embodiment, the material of the dummy structure 113 is the same as the material of the electrical trace 112, and the dummy structure 113 and the electrical trace 112 are disposed on the same sub-layer 111 at intervals. Specifically, the material of the electrical trace 112 and the material of the dummy structure 113 are both conductive and light-transmissive materials. The dummy structures 113 and the electrical traces 112 on the same sub-layer 111 are spaced apart so that the dummy structures 113 on the same sub-layer 111 are electrically isolated from the electrical traces 112.
Illustratively, in some implementations, the material of the electrical traces 112 includes, but is not limited to, indium tin oxide, silver-doped indium tin oxide, indium zinc oxide, or silver-doped indium zinc oxide, among others. Materials of dummy structure 113 include, but are not limited to, indium tin oxide, silver-doped indium tin oxide, indium zinc oxide, or silver-doped indium zinc oxide, among others.
In other embodiments, the material of the dummy structure 113 is a light-transmissive insulating material, and the light transmittance of the material of the dummy structure 113 is the same as the light transmittance of the material of the electrical trace 112.
In one embodiment, referring to fig. 3 and 7, the dummy structure 113 includes a plurality of sub-structures 1131, the dummy structure 113 has a first portion 113a and a second portion 113b, the sub-structure 1131 forms the first portion 113a, and the sub-structure 1131 forms the second portion 113 b; taking a plane perpendicular to the first direction as a projection plane, one of the electrical traces 112 forming the gap is a first electrical trace 112a, the first electrical trace 112a is adjacent to the first portion 113a, the other electrical trace 112 forming the gap is a second electrical trace 112b, and the second electrical trace 112b is adjacent to the second portion 113 b; in the first direction, the number of sub-structures 1131 of the first portion 113a is equal to the number of electrical traces 112 adjacent to the first electrical trace 112a, and the number of sub-structures 1131 of the second portion 113b is equal to the number of electrical traces 112 adjacent to the second electrical trace 112 b.
In this way, the number of the sub-structures 1131, through which the incident light passes through the first portion 113a, is equal to the number of the incident light passing through the electrical trace 112 adjacent to the first electrical trace 112a, and the light transmittance of the material of the sub-structure 1131 is the same as the light transmittance of the material of the electrical trace 112, so that the uniformity of the light transmittance of the area adjacent to the first electrical trace 112a is further ensured; the number of the sub-structures 1131 of the second portion 113b through which the incident light passes is equal to the number of the sub-structures 1131 of the second portion 113b through which the incident light passes through the electrical traces 112 adjacent to the second electrical trace 112b, and the light transmittance of the material of the sub-structures 1131 is the same as the light transmittance of the material of the electrical traces 112, so that the uniformity of the light transmittance of the adjacent area of the second electrical trace 112b is further ensured, and therefore, by adopting the design, the uniformity of the light transmittance of the whole display module 10 can be equalized as much as possible, so that the light intensity of the light beams reaching the light sensing device through different areas of the display module 10 is.
In an embodiment, referring to fig. 3 and fig. 7, the projection of the first portion 113a and the projection of the second portion 113b together at least cover a gap between the projections of the two adjacent electrical traces 112.
For example, referring to fig. 3, in an embodiment, in the first direction, the number of the sub-structures 1131 of the first portion 113a is one, the number of the electrical traces 112 adjacent to the first electrical trace 112a is one, and the number of the sub-structures 1131 of the first portion 113a is equal to the number of the electrical traces 112 adjacent to the first electrical trace 112 a; thus, the uniformity of the light transmittance of the area adjacent to the first electrical trace 112a can be equalized as much as possible; the number of sub-structures 1131 of the second portion 113b is one, the number of electrical traces 112 adjacent to the second electrical trace 112b is one, and the number of sub-structures 1131 of the second portion 113b is equal to the number of electrical traces 112 adjacent to the second electrical trace 112 b; in this way, the uniformity of the light transmittance of the area adjacent to the second electrical trace 112b can be equalized as much as possible, thereby equalizing the uniformity of the light transmittance of the entire display module as much as possible.
For example, referring to fig. 7, in another embodiment, in the first direction, the number of the sub-structures 1131 of the first portion 113a is two, the number of the electrical traces 112 adjacent to the first electrical trace 112a is two, and the number of the sub-structures 1131 of the first portion 113a is equal to the number of the electrical traces 112 adjacent to the first electrical trace 112 a; thus, the uniformity of the light transmittance of the area adjacent to the first electrical trace 112a can be equalized as much as possible; the number of sub-structures 1131 of the second portion 113b is one, the number of electrical traces 112 adjacent to the second electrical trace 112b is one, and the number of sub-structures 1131 of the second portion 113b is equal to the number of electrical traces 112 adjacent to the second electrical trace 112 b; in this way, the uniformity of the light transmittance of the area adjacent to the second electrical trace 112b can be equalized as much as possible, thereby equalizing the uniformity of the light transmittance of the entire display module as much as possible. The above is merely an exemplary illustration, and the number of the sub-structures 1131 included in the dummy structure 113 is not limited in the embodiments of the present application.
Note that, in fig. 1 to 8, the structure shown in the dashed box is the dummy structure 113, and the dashed box is used to indicate the dummy structure 113, and does not refer to a specific structural shape of the dummy structure 113; the dummy structure 113 may include one sub-structure 1131, or may include a plurality of sub-structures 1131.
In one embodiment, referring to fig. 9, the display module 10 includes a substrate and a light emitting layer, the light emitting layer includes a plurality of light emitting structures 12, the electrical traces 112 are electrically connected to the light emitting structures 12, and the electrical functional layer 11 and the light emitting layer are stacked on the substrate along a first direction. The substrate is used to support the electrical functional layer 11 and the light emitting layer. The electrical trace 112 is electrically connected to the light emitting structure 12 to transmit a control signal to the light emitting structure 12, where the control signal is an electrical signal. The light emitting structure 12 is controlled by the control signal to realize the display function of the display module 10.
