Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The use of "first," "second," and similar terms in the embodiments of the invention are not intended to indicate any order, quantity, or importance, but rather are used to distinguish one element from another; the word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. "left", "right", etc. are used only to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also change accordingly.
Example 1:
as shown in fig. 2 and 3, the present embodiment provides a display substrate having a plurality of first regions arranged in a row direction, in which a plurality of first signal lines arranged in the row direction are disposed; at least part of the first area comprises, including, a blank area 11 and a blank border area 12.
In addition, in the present embodiment, in the first region having the blank region 11 and the blank frame region 12, a part of the first signal lines includes the first signal segment 21 and the first connection segment 22 electrically connected to the first signal segment 21, and the first signal segment 21 and the first connection segment 22 are disposed on the same layer; and part of the first signal lines comprise a first signal segment 21 and a second connecting segment 23 electrically connected with the first signal segment 21, an insulating layer is arranged between the first signal segment 21 and the second connecting segment 23, and the first signal segment 21 and the second connecting segment are electrically connected through a through hole 3 on the insulating layer. The first connecting section 22 and the second connecting section 23 are located in the blank frame area 12.
The blank area 11 refers to an area of the display substrate where no display structure (including a display device, a driving device, and a signal line) is disposed, and the area is generally an area reserved for other devices of the display device, and for example, a hole may be formed in the area, and a camera, an infrared sensor, and the like may be mounted. The blank frame region 12 is mainly used for disposing signal lines that should pass through the blank region 11. The signal lines in the display substrate generally extend along a straight line, and the signal lines cannot be disposed in the blank region 11, so that the signal lines (e.g., the first connecting segment and the second connecting segment 23) can be changed in arrangement in the blank frame region 12 and extend along the periphery of the blank region 11, thereby bypassing the blank region 11 without interrupting the signal transmission. The space between the signal lines in the blank frame region 12 is relatively close, and a display device cannot be provided. The blank area 11 and the blank frame area 12 together constitute a non-display area in the first area.
In this embodiment, through the linkage segment and the 21 layering settings of first signal line of messenger's part, set up the insulating layer between first signal segment 21 and linkage segment, set up via hole 3 in the insulating layer, the linkage segment of messenger's first signal line is connected with the via hole 3 electricity that first signal segment 21 passes through the insulating layer, utilize double-deck wiring structure under the condition of the interval of guaranteeing between the first signal line, reduce the required area of arranging (the area of blank frame district 12 promptly) of the linkage segment of first signal line, thereby improve the screen of display substrate and account for the ratio, promote user's vision and watch experience.
In order to more clearly describe the display substrate of this embodiment, the first signal line includes a data line. Meanwhile, the display substrate includes a plurality of first regions, and a part of the first regions includes a blank region 11 and a blank frame region 12, and in this embodiment, the first regions having the blank region 11 and the blank frame region 12 are mainly modified, so the following first regions refer to the first regions having the blank region 11 and the blank frame region 12.
As shown in fig. 2, the first region of the display substrate includes a blank region 11, a blank frame region 12, and a display region 13. Wherein, the blank area 11 is located at the center of the first area, and the blank frame area 12 is located at the periphery of the blank area 11; the display area 13 is located at the periphery of the blank frame area 12.
The data line includes a first signal segment 21 and a connection segment connected to the first signal segment 21, and specifically, a part of the data line includes the first signal segment 21 and a first connection segment 22 electrically connected to the first signal segment 21, and a part of the data line includes the first signal segment 21 and a second connection segment 23 electrically connected to the first signal segment 21. The first signal segment 21 is located in the display area 13, and the connection segment (specifically, the first connection segment 22 or the second connection segment 23) is located in the blank frame area 12.
Specifically, as shown in fig. 2, in the display area 13 of the display substrate, the first signal segments 21 of the data lines are arranged along the row direction of the display substrate, and are straight lines extending along the column direction, and a plurality of display devices may be disposed along the column direction between two adjacent first signal segments 21. In the blank frame area 12 of the display substrate, the connection segments of the data lines are signal traces arranged along the row direction of the display substrate, and the specific shape may be a curve or a broken line extending along the outline of the blank area 11.
In the blank frame region 12, the distance between two adjacent connecting sections (two adjacent first connecting sections 22 or two adjacent second connecting sections 23) in the same conductive layer only needs to satisfy the conditions of insulation, static electricity prevention and the like, so that the width of the blank frame region 12 is reduced as much as possible, and the screen occupation ratio of the display substrate is improved.
Moreover, in this embodiment, the second connection segment 23 of the data line is layered with the first signal segment 21, and the two are electrically connected through the via hole 3 of the insulating layer, so that the occupied area (i.e., the area of the blank frame area 12) for arrangement of the connection signal segment is further reduced by using a double-layer wiring structure under the condition of ensuring the distance between the first signal lines, thereby further improving the screen occupation ratio of the display substrate and improving the visual viewing experience of the user.
Also taking the first signal line 5 as an example of a data line, for convenience of description, the data line 5 penetrating the display area 13 and the blank frame area 12 including the first connection segment 22 is referred to as a first data line, and the data line 5 including the second connection segment 23 is referred to as a second data line. With continued reference to fig. 2, the second data line includes a first signal segment 21 and a second connection segment 23 electrically connected and connected by a via hole 3 through the insulating layer; wherein the second connection segment 23 comprises a straight line portion extending in the same direction as the first signal segment 21, and a curved line portion surrounding a partial area of the blank space 11. The straight line part at the end of the second connection section 23 covers the via hole 3 on the insulating layer, which is connected with the first signal section 21, that is, the first signal section 21 of the second data line is connected with the straight line part of the second connection section 23 through the via hole 3 penetrating through the insulating layer. The connection node of the straight line portion and the curved line portion of the second connection section 23 is a winding inflection point of the second data line.
In the embodiment of the present disclosure, the second connection segment 23 of the second data line includes a straight line portion and a curved line portion, and the extending direction of the straight line portion is the same as the extending direction of the first signal segment 21, it can be understood that, when the line width of each position of the second data line is the same, the straight line portion of the second connection segment 23 is connected to the first signal segment 21 through the via hole 3 penetrating through the insulating layer, the contact area of the straight line portion and the first signal segment 21 should be the bottom surface area of the via hole 3, and if the curved line portion of the second connection segment 23 is connected to the first signal segment 21 through the via hole 3 penetrating through the insulating layer, the straight line portion of the second connection segment 23 and the first signal segment are connected through the via hole 3 of the insulating layer because the curved line portion has a certain curvature and the orthogonal projection on the insulating layer cannot completely cover the via hole 3, so that the contact area of the curved line portion and the first signal segment 21 is smaller than the bottom surface area, the first signal segment 21 and the second connection segment 23 can be well connected. In the disclosed embodiment, the winding inflection point of the second data line is located at the connection position of the straight line portion and the curved line portion of the second connection section 23, that is, on the second connection section 23, while for the first data line in the display substrate, the winding inflection point is on the first connection section 22, and the first connection section 22 and the second connection section 23 are disposed at different layers, so that each of the first data line and the second data line has a sufficient winding space, thereby effectively avoiding the problem of short circuit of each of the first data line and the second data line during winding.
In some examples, with continued reference to fig. 2, the first data lines and the second data lines are alternately arranged, that is, the first connection segments 22 and the second connection segments 23 are alternately arranged, so that the first data lines and the second data lines have more sufficient routing space. Further, the projections of the first connection segment 22 of the first data line and the second connection segment 23 of the second data line on the insulating layer at least partially overlap, for example, the projections of the curved portion of the first connection segment 22 and the curved portion of the second connection segment 23 on the insulating layer at least partially overlap. Thus, the wiring space can be reduced.
In some examples, with continued reference to fig. 2, a straight line passing through the center of the blank space 11 in the column direction is taken as a symmetry axis, wherein the center has different definitions for different shapes, and for an equilateral polygon, the center refers to the intersection of perpendicular lines of each side; for circular (including elliptical) the center is the center of the circle. For example: when the blank area 11 is circular, the center of the blank area is the center of the circular blank area 11, and the symmetry axis is the extension of the diameter of the blank area 11 along the column direction. In the embodiments of the present disclosure, the blank area 11 is a circle, and an extension line of a diameter of the blank area 11 in the column direction is taken as an example of a symmetry axis. Wherein each via hole 3 for connecting the first signal segment 21 and the second connection segment 23 of the second data line is mirror-symmetrical along the symmetry axis. It is understood that the vias 3 for connecting the first signal segment 21 and the second connection segment 23 are located in the blank frame area 12, i.e. the vias 3 located in the blank frame area 12 are mirror symmetric along the extension direction of the diameter of the blank area 11 in the column direction. This kind of mode is convenient for the preparation of via hole 3, and avoids via hole 3 to concentrate and sets up in a certain region of blank frame region 12, and leads to display substrate toughness to receive the influence.
In some examples, with continued reference to fig. 2, with an extension line of the diameter of the blank area 11 in the column direction as a symmetry axis, the winding inflection points of the first and second data lines are mirror-symmetric along the symmetry axis. It is understood that the winding inflection points of the first and second data lines are located in the blank frame region 12, that is, the winding inflection points located in the blank frame region 12 are mirror-symmetrical in the extending direction of the diameter of the blank region 11 in the column direction. By setting the winding inflection point in this manner, the limited blank frame region 12 can be made to provide a sufficient wiring space for the first data line and the second data line.
In some examples, with reference to fig. 2, part of the structure of the first signal segment 21 of the first data line and the first signal segment 21 of the second data line is located in the blank frame area 12, so that the connection position of the first signal segment 21 and the second connection segment 23 of the second data line can be located in the blank frame area 12, that is, the via hole connecting the first signal segment 21 and the second connection segment 23 is disposed in the blank frame area 12, and by this way, the problem of poor display caused by more via holes 3 existing in the display area 11 can be effectively avoided.
In some examples, with continued reference to fig. 2, for any one of the second data lines, the connection position (i.e., the position corresponding to the via hole 3) of the first signal segment 21 and the second connection segment 23 to the winding inflection point is a first line segment; and in each second data line, the lengths of the first line segments of at least part of the second data lines are different. In one example, with an extension line of the diameter of the blank area 11 in the column direction as the axis of symmetry, the length of the first line segment closer to the axis of symmetry is greater than the length of the first line segment farther from the axis of symmetry. In one example, for any two adjacent first line segments, the length of the first line segment closer to the symmetry axis is greater than the length of the first line segment farther from the symmetry axis. In addition, the lengths of the first line segments which are the same distance from the symmetry axis are equal.
Preferably, as shown in fig. 2, the blank region 11 has a circular shape, and the blank frame region 12 has a ring shape. Further, the shape of at least part of the first connecting section comprises an arc and/or the shape of at least part of the second connecting section 23 comprises an arc. As shown in fig. 2, the shape of the connection segment near the blank space 11 may only include an arc, and the shape of the connection segment far from the blank space 11 may include an arc and a straight line, where two ends of the arc are straight line portions, and the straight line portion is connected to the first signal segment.
Preferably, in the same first area having the blank area 11 and the blank frame area 12, one data line of any two adjacent data lines includes the first signal segment 21 and the first connection segment 22; the other data line includes a first signal segment 21 and a second connection segment 23.
As shown in fig. 2, in the first region of the display substrate, the data lines (i.e., the data lines including the first connection segment 22) of the first signal segment 21 and the connection segment disposed on the same layer are spaced apart from the data lines (i.e., the data lines including the second connection segment 23) of the first signal segment 21 and the connection segment disposed on a layer. Compared with the case that the connection sections of two adjacent data lines are located on the same layer, the wiring manner of the embodiment that the connection sections of two adjacent data lines are respectively located on different layers can maximally compress the wiring areas of the same number of data lines, reduce the area of the blank frame region 12, and improve the screen occupation ratio of the display substrate. It should be noted that, in the display substrate, the spacing distance between adjacent data lines should be above a preset value, so as to avoid the occurrence of undesirable phenomena such as static electricity and coupling between the data lines.
Preferably, in at least one group of two adjacent data lines, the orthographic projection of the first signal segment 21 on the substrate partially overlaps with the orthographic projection of the second connecting segment 23 on the substrate.
As shown in fig. 2, the data lines in the first area are divided into a plurality of groups, each group of data lines including two adjacent data lines. Two data lines in the same group respectively comprise a first connecting section 22 and a second connecting section 23, the middle part of the first connecting section 22 is overlapped with the orthographic projection part of the middle part of the second connecting section 23 on the substrate, so that the width of the two data lines in the blank frame area 12 is reduced by half in the row direction, and the area compression of the blank frame area 12 is realized. It can be understood that, since the first connection segment 22 and the second connection segment 23 belong to different data lines and are respectively connected to the two first signal segments 21 disposed on the same layer, orthographic projections of the two segments of the first connection segment 22 and the two segments of the second connection segment 23 on the substrate are not overlapped to avoid short circuit of the two data lines. In addition, in the embodiment, since the first connecting section 22 and the second connecting section 23 are located on different layers, and an insulating layer is disposed between the two layers, the normal operation of the display substrate is not affected by the overlapping of the orthographic projections of the first connecting section and the second connecting section on the substrate.
Preferably, as shown in fig. 3, the embodiment further includes a second signal line 4, and specifically, the second signal line 4 may be a gate line, which is insulated from the data line. Further preferably, the second connection segment 23 of the data line may be disposed on the same layer and have the same material as the gate line. That is, both may be formed using a single patterning process to simplify the complexity of the manufacturing process of the display substrate.
Specifically, as shown in fig. 3, the gate lines are arranged along the column direction of the display substrate and extend along the row direction. At the periphery of the circular blank region 11 (i.e. the annular blank frame region 12), a plurality of gate lines extend around the edge profile of the blank region 11, and a plurality of second connection segments 23 of the data lines also extend around the edge profile of the blank region 11. The data lines are located closer to the circular blank area 11 than the gate lines, so as to avoid the second connection segments 23 crossing the gate lines.
It can be understood that, in general, the number of data lines in the display substrate is three times that of the gate lines. In the prior art, when the data lines are all disposed in the same layer, the width of the blank frame region 12 formed by the first connection segment 22 is at least three times the width of the blank frame region 12 formed by the gate lines. Therefore, in this embodiment, one third of the data lines are arranged in a double-layer wiring structure, that is, one third of the data lines include the second connection segments 23, and the second connection segments 23 and the gate lines are arranged in the same layer, so that the width of the blank frame area 12 of the display substrate formed is about 2/3 of the width of the blank frame area 12 in the prior art, that is, the width of the blank frame area 12 of about 1/3 can be reduced, and the visual experience of the user is obviously improved.
Preferably, in the display substrate of this embodiment, the first signal line further includes a touch line. The touch lines may be arranged along a row direction of the display substrate and arranged along a column direction of the display substrate. Similar to the data lines, the touch lines in the present embodiment may be arranged in a double-layer wiring structure, and reference may be made to the arrangement of the data lines, which will not be described in detail herein.
It can be understood that when the first signal lines of the display substrate further include the touch lines, the number of the first signal lines (including the data lines and the touch lines) of the display substrate is more than three times the number of the second signal lines 4 (gate lines), and at this time, the effect of compressing the width of the blank bezel area 12 is more significant.
Example 2:
the present embodiment provides a display panel including any one of the display substrates provided in embodiment 1.
Specifically, the display panel in this embodiment may be applied to any product or component with a display function, such as a mobile phone, a tablet computer, a television, a display, a notebook computer, and an advertisement screen.
