The driver substrate comprises a plurality of scan lines 11 parallel to the first direction 10 and a plurality of data lines 12 parallel to a second direction 20. The second direction 20 intersects the first direction 10 and is arranged at a predetermined angle to the first direction 10. Each of the plurality of scan lines 11 and each of the plurality of data lines 12 are located in the display area 100, and one end of each of the plurality of scan lines 11 close to the fanout area 200 is provided with a scan trace 111 extending into the fanout area 200.
Each of the plurality of data lines 12 is connected to a data bridging line 121. The data lines 12 and the data bridging line 121 are arranged in different layers. One end of the data bridging line 121 and the data lines 12 are connected in the display area 100. The other end of the data bridging line 121 extends into the fanout area 200 along the first direction 10.
It is noted that, as shown in
It is noted that the second direction 20 intersects the first direction 10 and is set to form a predetermined angle with the first direction 10. Obviously, the second direction 20 and the first direction 10 are formed in an intersected arrangement. That is, the second direction 20 is not parallel to the first direction 10, and the second direction 20 is arranged at a predetermined angle with the first direction 10. Specifically, the predetermined angle between the second direction 20 and the first direction 10 can be 90 degrees, one end of the data bridging line 121 is connected to the data lines 12 in the display area 100, and the other end of the data bridging line 121 extends into the fanout area 200 along the first direction 10. Herein, the other end of the data bridging line 121 extends into the fanout area 200 along the first direction 10, and the portion of the data bridging line 121 in the fanout area 200 can be arranged in a display arrangement such as a broken line or an arc line. That is, after the data bridging line 121 extends into the fanout area 200 along the first direction 10, it is also possible to extend along various different paths in the fanout area 200, which is not limited here. In addition, in the present embodiment, a flexible printed circuit (FPC) 13 is provided on a side of the driver substrate close to the fanout area 200. The scan line 11 is connected to the flexible circuit board 13 through the scan trace 111 extending into the fanout area 200, and the data line 12 is connected to the flexible circuit board 13 through the data bridging line 121 extending into the hub area 200.
In one embodiment, referring to
The insulating layer 14 is defined with a plurality of via holes 141 located in the display area 100, and each of the data lines 12 correspondingly passes through one of the plurality of the via holes 141 to connect one of the data bridging lines 121.
It is noted that the data lines 12 and the data bridging lines 121 are arranged in different layers to avoid interleaving and short-circuiting in the display area 100. That is, a wider frame problem caused by routing from a side of the driver substrate can also be avoided. In the present embodiment, the driver substrate further comprises an insulating layer 14. Each of the data lines 12 is arranged on a side of the insulating layer 14, and each of the data bridging lines 121 is arranged on a side of the insulating layer 14 away from the data lines 12 so as to realize the arrangement of the data lines 12 and the data bridging lines 121 in different layers. In addition, the insulating layer 14 is defined with a plurality of via holes 141 in the display area 100, and each data line 12 correspondingly passes through one of the via holes 141 to connect to one of the data bridging lines 121 so that one end of the data bridging line 121 is connected to the data line 12 in the display area 100. Specifically, referring to
In one embodiment, referring to
It is noted that each of the scan lines 11 is arranged on a side of the insulating layer 14 away from the data line 12. That is, short-circuits due to a mesh-like interleaving of the scan lines 11 and the data lines 12 are prevented. Specifically, the scan line 11 and the data bridging line 121 are arranged on the same layer and form an integral structure. Obviously, routing of the scan line 11 and the data bridging line 121 are both arranged along the first direction 10, and each of the scan lines 11 and each of the data bridging lines 121 are arranged at intervals in the second direction 20. Please refer to
It is noted that the driver substrate further comprises a thin film transistor (TFT), and the thin film transistor (not shown in the figure) comprises a gate provided on the same layer as the scan lines 11 and the data bridging lines 121 and a source electrode and a drain electrode provided one the same layer as the data lines 12. Specifically, the thin film transistor may be a TFT structure such as a top gate structure, a bottom gate structure, etc., which is not limited herein.
In one embodiment, referring to
Among the two adjacent groups of data line 12, the via 141 corresponding to one group of the data line 12 is located on one side of the center line 30, and the via hole 141 corresponding to the other group of data line 12 is located on the other side of the center line 30.
It is noted that the data line 12 is connected to a data bridging line 121 through a corresponding via hole 141 and receives a data signal. In this process, the closer to the position of the via hole 141 on each of the data lines 12, the smaller the impedance and the higher the charging efficiency. As a result, charging of the data lines 12 are not balanced, which leads to the problem of uneven display brightness and darkness. Obviously, by arranging two adjacent groups of the data line 12 on both sides of the center line 30 through the corresponding via holes 141, so that the unevenly charged positions of the two adjacent groups of the data line 12 can be interleaved and the bright and dark positions of the adjacent two groups of the data line 12 can be complementary to each other.
In one embodiment, referring to
It is noted that when the group of data line 12 comprises only one of the data lines 12, among two adjacent groups of data line 12, a distance from the via hole 141 corresponding to one group of the data line 12 close to the fanout area 200 to the center line 30 is greater than or equal to a distance from the via hole 141 corresponding to one group of the data line 12 away from the fanout area 200 to the center line 30. That is, the far of the distance from the via hole 141 corresponding to the groups of data line 12 close to the fanout area 200 to the center line 30 is, the near of the distance from the groups of data line 12 close to the fanout area 200 to the center line 30 obviously is. In addition, the far of the distance from the via hole 141 on the data line 12 to the center line 30 is, the more uneven charging on the data line 12 is. In the present embodiment, in each of the groups of data line 12, the far of the distance from the via hole 141 corresponding to the groups of data line 12 close to the fanout area 200 to the center line 30 is, that is, the near of the distance from the groups of data line 12 close to the fanout area 200 to the center line 30 obviously is so that the via hole 141 is arranged at a place close to the center line 30 when the data line far from the fanout area 200 is standing a greater impendence of the data bridging line 121. By forming a less distance difference from the via hole 141 to both ends of the data line 12, an impendence of the data line 12 away from the fanout area is reduced. Therefore, impendence differences to various data lines 12 of the driver substrate can be overall and maximumly reduced to ensure the image driving effects of the driver substrate.
