[0033] The present application is described in detail below with reference to the accompanying drawings and optional embodiments.

[0034] like Figure 1 As shown, Figure 1 The RGB pixels are arranged vertically, which is a three-gate architecture, that is, the number of gate scanning lines 120 becomes three times of the original number, and the number of data lines 110 becomes one-third of the original number. Because the number of data lines is reduced, the number of source driver chips can be reduced to one-third of the original design architecture, the number of source driver chips is reduced, and the number of gate driver chips is increased. However, the source driver chip is much more complex than the gate driver chip and is very expensive. Therefore, reducing the number of source driver chips can greatly reduce the cost. However, the vertical arrangement of RGB will result in the charging time of each row being only one-third of the original panel, which is easy to cause insufficient charging. Therefore, the present application discloses a method such as Figure 1The display panel 100 shown in the figure comprises a plurality of data lines 110, a plurality of scan lines 120 and a common line 130, wherein the common line 130 comprises a plurality of sub-common lines 131; the plurality of data lines 110 and the plurality of scan lines 120 are crisscrossed to form a plurality of pixel regions 140, and each pixel region 140 is provided with a corresponding sub-common line 131; wherein the number of data lines 110 is m, the number of scan lines 120 is n; the common line 130 further comprises a plurality of horizontal wirings 132, each of which is A horizontal line 132 is arranged to cross the data line 110, connecting two adjacent sub-common lines 131 along the direction of the scan line 120; a plurality of vertical lines 133, each of which is arranged to cross the scan line 120, connecting two adjacent sub-common lines 131 along the direction of the data line; the plurality of horizontal lines 132 and the vertical lines connect all the sub-common lines 131 to form the common line 130, and the common line 130 is connected to a common voltage signal; Figure 1 Each sub-common line 131 is connected to two horizontal lines 132 and a vertical line 133, and all the sub-common lines 131 are connected, thereby increasing the area of ​​the common line 130, and then reducing the resistance of the common line 130, so that the loss of the common line 130 of the display panel 100 with a three-gate structure is reduced; however, there will be parasitic capacitance between too many horizontal lines 132 and vertical lines 133 and the data line 110 and the scan line 120, resulting in an increase in the load of the data line 110. In this regard, the applicant has disclosed the following solutions.

[0035] like Figure 2 and Figure 3The present application discloses a display device 10, comprising a driving circuit 200 and a display panel 100, wherein the display panel 100 comprises a display area 101 and a non-display area 102; a plurality of data lines 110, a plurality of scan lines 120 and a common line 130 are arranged in the display area 101, wherein the common line 130 comprises a plurality of sub-common lines 131; the plurality of data lines 110 and the plurality of scan lines 120 are crisscrossed to form a plurality of pixel areas 140, wherein each pixel area 140 is correspondingly provided with a sub-common line 131; wherein the number of data lines 110 is m, the number of scan lines 120 is n; the common line 130 also comprises a plurality of horizontal Routing 132, each of the horizontal routing lines 132 is cross-arranged corresponding to the data line 110, connecting two adjacent sub-common lines 131 along the direction of the scan line 120; multiple vertical routing lines 133, each of the vertical routing lines 133 is cross-arranged corresponding to the scan line 120, connecting two adjacent sub-common lines 131 along the direction of the data line; the number of the horizontal routing lines 132 is less than or equal to m; the number of the vertical routing lines 133 is less than or equal to n-1; the multiple horizontal routing lines 132 and the vertical routing lines connect all the sub-common lines 131 to form the common line 130, and the common line 130 is connected to a common voltage signal.

[0036] Compared with the conventional solution of setting a whole common line 130 in the direction of the scan line 120 or the data line, the present application reduces the number of horizontal lines 132 and vertical lines 133, thereby reducing the parasitic capacitance generated between the horizontal line 132 and the data line 110, thereby reducing the load of the data line 110, and can reduce the parasitic capacitance generated between the vertical line 133 and the scan line 120, thereby reducing the load of the scan line 120; that is, by reducing the overlapping area between the common line 130 and the data line 110 or the scan line 120, the effect of reducing the parasitic capacitance is achieved, thereby reducing the load of the data line 110 and the scan line 120.

[0037] like Figure 3As shown, the display panel 100 includes a first metal layer 103, a second metal layer 104 and a transparent electrode layer 105 which are sequentially arranged from bottom to top; the scan line 120 and the common line 130 are formed in the first metal layer 103; the data line 110 is formed in the second metal layer 104; the pixel electrode is formed in the transparent electrode layer 105; the scan line 120 and the data line 110 cross to form a pixel area 140; the pixel electrode and the common line 130 are correspondingly arranged in the pixel area 140; the display panel 100 includes a display area 101 and a non-display area 102; a plurality of data lines 110, a plurality of scan lines 120 and a common line 130 are arranged in the display area 101, and the common line 130 includes a plurality of sub-common lines 131; a plurality of the data lines 110 and the plurality of the scan lines 120 are crisscrossed to form a plurality of pixel areas 140, and a sub-common line 131 is correspondingly arranged in each pixel area 140.

[0038] Among them, Figure 3 As shown, the number of horizontal lines 132 along a scan line 120 is m / 2, and the number of vertical lines 133 along a data line is n / 2; one horizontal line 132 is arranged for every data line 110, and one vertical line 133 is arranged for every scan line 120.

[0039] In the above embodiment, with respect to the scheme that the four sides of each sub-common line 131 are connected to the adjacent sub-common line 131 through two horizontal lines 132 and two vertical lines 133; each sub-common line 131 is connected to another adjacent sub-common line 131 only through one horizontal line 132; each sub-common line 131 is connected to another adjacent sub-common line 131 only through one vertical line 133, so that each sub-common line 131 is connected to only one horizontal line 132 and one vertical line 133, half the number of horizontal lines 132 of the data lines 110 and half the number of vertical lines 133 of the scan lines 120 can also be used. All sub-common lines 131 are connected, and a horizontal line 132 is set for every other data line 110, and a vertical line 133 is set for every other scan line 120. The number of horizontal lines 132 and vertical lines 133 is halved, which not only reduces the parasitic capacitance to the data lines 110 and the scan lines 120, but also makes the spacing uniform, so that the parasitic capacitance of the data lines 110 and the scan lines 120 in the display area 101 is more uniform, making the display more uniform, reducing the load on the data lines 110 and the scan lines 120, improving the problem of insufficient charging, and avoiding the problem of uneven display brightness caused by the brightness of one area increasing while the brightness of another area does not increase.

[0040] like Figure 3As shown, on the basis of the above embodiment, it is further arranged that: m pixel areas 140 are arranged along a scan line 120 direction, and n pixel areas 140 are arranged along a data line direction; wherein, in the pixel areas 140 along the odd-numbered scan lines 120, m / 2 horizontal wirings 132 are respectively arranged corresponding to the data lines 110 of the odd-numbered columns; in the pixel areas 140 along the even-numbered scan lines 120, m / 2 horizontal wirings 132 are respectively arranged corresponding to the data lines 110 of the even-numbered columns; in the pixel areas 140 along the odd-numbered data lines 110, m / 2 vertical wirings 133 are respectively arranged corresponding to the scan lines 120 of the odd-numbered rows; in the pixel areas 140 along the even-numbered data lines 110, m / 2 horizontal wirings 132 are respectively arranged corresponding to the scan lines 120 of the even-numbered rows.

[0041] like Figure 3 As shown, in the above embodiment, the first row and first column sub-common line 131 is connected to the second row and first column sub-common line 131 through a vertical line 133, the second row and first column sub-common line 131 is connected to the second row and second column sub-common line 131, and the second row and second column sub-common line 131 is connected to the third row and second column sub-common line 131 through a vertical line 133, and the sub-common lines 131 on the diagonal of the display panel 100 are connected to form a common line 130 through horizontal lines 132 and vertical lines 133 in sequence, and all the sub-common lines 131 are connected through a stepped connection routing method, while reducing the horizontal lines 132 and the vertical lines 133, the problem of large resistance caused by connecting some areas only in series is avoided as much as possible, and the resistance of the common line 130 is reduced by parallel connection, thereby reducing impedance loss. In addition, similar to the above, the load of the data line 110 and the scan line 120 can also be reduced, so as to achieve a uniform display effect.

[0042] It should be noted that Figure 3 Each pixel area 140 is a red sub-pixel 161 or a green sub-pixel 162 or a blue sub-pixel 163. A pixel 160 includes a red sub-pixel 161, a green sub-pixel 162 and a blue sub-pixel 163 arranged vertically. In this embodiment, the pixels are arranged in a vertical RGB arrangement mode, which is a three-gate structure, so that the number of scan lines 120 becomes 3 times the original number, and the number of data lines 110 becomes 1 / 3 of the original number, but the number of pixels in each column remains unchanged, so that the ultra-high-definition display originally arranged horizontally with RGB still maintains the ultra-high-definition pixel standard after the vertical arrangement of RGB. For the three-gate structure, the charging time of each row is only one-third of the charging time of the horizontal RGB arrangement, which can easily cause insufficient charging. The present application reduces the parasitic capacitance of the data line 110 and the scan line 120, so that the load of the data line 110 and the scan line 120 is reduced, the charging delay is reduced, and the charging efficiency is improved.

[0043] like Figure 4 This application Figure 3 A partial enlarged schematic diagram of Figure 4 Each of the sub-common lines 131 includes a first sub-common line segment 134 and a third sub-common line segment 136 parallel to the data line 110, and a second sub-common line segment 135 and a fourth sub-common line segment 137 parallel to the scan line 120. The first sub-common line segment 134, the second sub-common line segment 135, the third sub-common line segment 136 and the fourth sub-common line segment 137 are connected end to end; the horizontal wiring 132 connects the third sub-common line segment 136 of a sub-common line 131 with the first sub-common line segment 134 of another adjacent sub-common line 131; the vertical wiring 133 connects the second sub-common line segment 135 of a sub-common line 131 with the fourth sub-common line segment 137 of another adjacent sub-common line 131; by lengthening the length of the sub-common line 131, the overlapping area of ​​the sub-common line 131 and the pixel electrode is larger, thereby making the storage capacitor larger, and more electrical energy is stored during display. In addition, Figure 4 As shown, the horizontal routing line 132 is arranged in the middle position of the third sub-common line segment 136, away from the active switch arranged in the pixel area 140, and the vertical routing line 133 is also arranged in the fourth sub-common line segment 137 away from one end of the active switch in the pixel area 140. The horizontal routing line 132 and the vertical routing line 133 avoid the active switch to prevent the routing from interfering with the active switch and also reduce the generation of parasitic capacitance.

[0044] like Figure 5 The present application also discloses Figure 3In another different implementation manner, in each column of the pixel area 140, x consecutive pixel area groups 150 are grouped into one pixel area group 150; the x sub-common lines 131 in one pixel area group 150 are connected via x-1 vertical lines 133; a horizontal line 132 is provided between each of the adjacent pixel area groups 150 along the direction of the scan line 120 to connect the sub-common lines 131 corresponding to the pixel area groups 150 provided along the direction of the scan line 120; the pixel area 140 in each column is divided into n / x pixel area groups 150, where x is a natural number greater than or equal to 2 and less than or equal to n, and n / x is an integer. Different from the previous embodiment, the number of vertical lines 133 in this embodiment is relatively large, and the number of horizontal lines 132 is relatively small. The vertical lines 133 are arranged on the transparent electrode layer 105, which is far away from the scanning lines 120 of the first metal layer 103, and the generated parasitic capacitance is small. The horizontal lines 132 are arranged on the first metal layer 103, which is close to the data lines 110 arranged on the second metal layer 104, and the generated parasitic capacitance is large. Setting the number of horizontal lines 132 to be smaller is beneficial to reducing the load of the data lines 110, and thus can also improve the charging efficiency.

[0045] like Figure 5 As shown, when x is equal to 3, the display area 101 includes a plurality of pixels, and the pixels include vertically arranged red sub-pixels, green sub-pixels and blue sub-pixels; that is, one pixel area 140 is a red sub-pixel or a green sub-pixel or a blue sub-pixel, and each of the pixel area groups 150 includes the vertically arranged red sub-pixels, green sub-pixels and blue sub-pixels; m pixel areas 140 are arranged along the scan line 120 direction, and n pixel areas 140 are arranged along the data line direction; m / 3 pixels are arranged along the data line direction, and n pixel areas are arranged along the scan line 120 direction, and one red sub-pixel, green sub-pixel or blue sub-pixel is arranged in each of the pixel areas 140. In this embodiment, the pixels are arranged in a vertical RGB arrangement mode, which is a three-gate structure, so that the number of scan lines 120 becomes three times of the original number, and the number of data lines 110 becomes 1 / 3 of the original number, but the number of pixels in each column remains unchanged, so that the ultra-high-definition display that originally arranged RGB horizontally can still maintain the ultra-high-definition pixel standard after arranging RGB vertically.
