Referring to fig. 1 to 6, an embodiment of the present disclosure provides an array substrate including a display region 1 and a plurality of gate lines disposed on a substrate 14. Each of the gate lines is divided into a first gate line 3 and a second gate line 13, each of the gate lines extends in a first direction, each of the gate lines is spaced in a second direction, and the second direction intersects with the first direction. The display area 1 includes a plurality of common electrodes distributed in an array on a substrate 14, the common electrodes are multiplexed as touch electrodes 2 during touch scanning, a first conductive part 4 and a second conductive part 5 are arranged in a staggered manner in a spacing area of two adjacent touch electrodes 2 in a second direction, the first conductive part 4 is electrically connected with one touch electrode 2, and the second conductive part 5 is electrically connected with the other touch electrode 2.
In a specific embodiment, an orthogonal projection of the first conductive part 4 on the substrate 14 and an orthogonal projection of the second conductive part 5 on the substrate 14 both overlap an orthogonal projection of the first gate line 3 on the substrate 14, and an orthogonal projection of the second gate line 13 on the substrate 14 overlaps an orthogonal projection of the touch electrode 2 on the substrate 14.
In the actual use process, the first conductive parts 4 and the second conductive parts 5 are arranged in a staggered mode, the first grid lines 3 are arranged in an overlapped mode with the first conductive parts 4 and the second conductive parts 5, the adjacent first conductive parts 4 and the adjacent second conductive parts 5 are influenced oppositely by the closing or opening pulling of the first grid lines 3 in the charging time of the first grid lines 3, the influence directions of the charging rates of the edges of the touch electrodes 2 are opposite, therefore, the charging rates of the edges of the touch electrodes 2 are visually offset in the same first direction, and the cross grain problem is solved.
It should be noted that the first direction in the embodiment of the present disclosure is a row setting direction, and the second direction is a column setting direction.
In a specific embodiment, at least one first grid line 3 is provided, and the first grid line 3 is connectedThe grid line driving signal output by the over-driving circuit is controlled, and the driving circuit is controlled by a clock signal. The number M of the first gate lines 3 and the number N of the clock signals satisfy:
in an actual use process, the first gate line 3 is a gate line with a charging difference on the touch electrode 2. The first gate line 3 is driven by a gate line driving signal generated by a driving circuit controlled by a clock signal, so that the first gate line 3 can be in a charging process. In the Clock GOA driving display design, subtracting one from half the number of CLK, that is, the number of gate lines with charging difference on the touch electrode 2, that is, the number of first gate lines 3. As an example, when the 8Clock GOA is 3 rows of gate lines 3 for pre-charging, and 1 row of gate lines 3 for effective charging, the number of Clock signals in the touch electrode 2 is 8 and the number of first gate lines 3 is 3 under the driving control of the 8Clock GOA; in the 12Clock GOA, 5 rows of gate lines 3 are precharged, and 1 row of gate lines 3 are effectively charged, so that the number of Clock signals in the touch electrode 2 under the driving control of the 12Clock GOA is 12, and the number of first gate lines 3 is 5; in the 16Clock GOA, 7 rows of gate lines 3 are precharged, and 1 row of gate lines 3 are effectively charged, so that the number of Clock signals in the touch electrode 2 is 16 and the number of first gate lines 3 is 7 under the driving control of the 16Clock GOA.
Referring to fig. 2 and 6, in a specific embodiment, an orthogonal projection of the second gate line 13 on the substrate 14 overlaps an orthogonal projection of the touch electrode 2 on the substrate 14, that is, the second gate line 13 is located between middle positions of the touch electrode 2; at least one second gate line 13 is provided.
When the second gate line 13 is opened to charge the corresponding pixel, the voltage of the touch electrode 2 serving as the common electrode is influenced by the downward pulling from the opening to the closing of the first gate line 3 located above in the second direction and the upward pulling from the closing to the opening of the first gate line 3 located below in the second direction, so that the touch electrode 2 overlapped with the second gate line 13 has no difference in pixel charging rate in the charging process, and the cross striation problem does not occur. With reference to fig. 1, therefore, the first gate line 3 is overlapped with the two adjacent touch electrodes 2 at the same time, so that when the first gate line 3 is turned on for charging, the two adjacent touch electrodes 2 are influenced oppositely by the turning-off or turning-on pulling of the first gate line 3, and the influence directions of the charging rates are opposite, so that the first gate line 3 and the second gate line are visually offset in the same second direction, and the cross striation problem is solved.
Referring to fig. 6, a graph showing the variation of the array substrate with time and voltage under the 8Clock GOA driving display is shown. In the 8Clock GOA driving display, the number of the first gate lines 3 in the touch electrode 2 is 3, and the number of the second gate lines 13 in the touch electrode 2 is 39, so the total number of the first gate lines 3 and the second gate lines 13 in the touch electrode 2 is 45. As shown in fig. 6, during the charging time of the first gate line 3 corresponding to the touch electrode 2, the voltage of the touch electrode 2 is pulled only by the falling edge of the adjacent row, and during the charging time of the second gate line 13 corresponding to the touch electrode 2, the voltage of the touch electrode 2 is pulled by the rising edge and the falling edge of the adjacent row. Therefore, the difference of the first gate line 3 and the second gate line 13 in the same touch electrode 2 to the voltage pulling of the touch electrode 2 causes the charging difference in the touch electrode 2, and the cross striation problem occurs.
Referring to fig. 1 to 6, in a specific embodiment, the first conductive part 4 and the second conductive part 5 are respectively connected to two opposite sides of the touch electrode 2 in the second direction. After the touch electrodes 2 are distributed on the display area 1 in an array manner, a first conductive part 4 and a second conductive part 5 are simultaneously arranged on a separation area between two adjacent touch electrodes 2 in the second direction, and the first conductive part 4 and the second conductive part 5 are distributed in a staggered manner. Therefore, under the condition that the first grid line 3 is charged, the pulling directions of the first conductive part 4 and the second conductive part 5 are opposite, so that the cross striation phenomenon is visually solved.
In an alternative embodiment, the first conductive parts 4 are formed on one side of the touch electrodes 2 in the second direction, the second conductive parts 5 are formed on the other side of the touch electrodes 2 in the second direction, and in the case that the touch electrodes 2 are distributed in an array, the first conductive parts 4 and the second conductive parts 5 between two adjacent touch electrodes 2 are distributed in a staggered manner. The first conductive part 4 and the second conductive part 5 are both arranged on the touch electrode 2, so that the touch electrode 2 is convenient to prepare, and the reliability of the electrical connection between the first conductive part 4 and the touch electrode 2 and the second conductive part 5 can be ensured.
In a specific embodiment, a plurality of the first conductive parts 4 and a plurality of the second conductive parts 5 are provided, the first conductive parts 4 are uniformly spaced in the first direction, and the second conductive parts 5 are uniformly spaced in the first direction. The number of the first conductive parts 4 and the number of the second conductive parts 5 are the same, so that the plurality of first conductive parts 4 and the plurality of second conductive parts 5 can be staggered one by one to form a staggered distribution form. By arranging the first conductive part 4 and the second conductive part 5 in a plurality, the first conductive part 4 and the second conductive part 5 are less affected by the pulling of the first conductive part 3 under the charging condition of the first grid line 3, and the visual charging disparity rate is further reduced.
In an alternative embodiment, the width of the first conductive portion 4 and the width of the second conductive portion 5 are equal. Under the condition that the first grid lines 3 are charged, in two adjacent touch electrodes 2 in the second direction, the parts of the touch electrodes 2 pulled upwards by the acting force of the first grid lines 3 are the same as the parts of the touch electrodes 2 pulled downwards by the acting force of the first grid lines 3, so that the visual effect of the charging difference rate is reduced, and the problem of cross striations is solved.
In a particular embodiment, the first conductive portion 4 and the second conductive portion 5 are the same shape. By arranging the first conductive parts 4 and the second conductive parts 5 in the same shape, after the first conductive parts 4 and the second conductive parts 5 are arranged in a staggered manner, the distance between the first conductive parts 4 and the second conductive parts 5 is uniform, the structure is compact, and the matching between the first conductive parts 4 and the second conductive parts 5 is facilitated.
In a specific embodiment, a sub-pixel set is further disposed on the display area 1, and the sub-pixel set includes a first sub-pixel, a second sub-pixel, and a third sub-pixel disposed at intervals in the first direction. In the using process, the first sub-pixel is a blue pixel, the second sub-pixel is a red pixel, and the third sub-pixel is a green pixel; the display area 1 displays different display effects by a plurality of sub-pixel sets. The lengths of the first conductive parts 4 in the first direction are the same, and the length of the first conductive parts 4 in the first direction is an integral multiple of the length of the sub-pixel sets in the first direction. That is, the length of the first conductive part 4 in the first direction may be the same as the length of the sub-pixel set in the first direction, or the length of the first conductive part 4 in the first direction is a multiple of the length of the sub-pixel set in the first direction, so as to ensure the display effect of the array substrate.
In a particular embodiment, the shape of the first conductive part 4 based on the orthographic projection of the substrate 14 is a parallelogram. Specifically, the shape of the first conductive part 4 may be a rectangle, a square, a parallelogram, or the like. Similarly, the shape of the first conductive part 4 may be such that both side walls of the first conductive part 4 in the first direction have the same shape based on the orthographic projection of the display region 1 and are stepped. When the step shape is provided, the number of steps is not limited in this application. Similarly, the first conductive part 4 may have a shape in which two side walls of the first conductive part 4 in the first direction are arranged in parallel, so that the widths of the respective positions of the first conductive part 4 in the first direction are equal to each other, thereby ensuring the performance of the array substrate.
In an optional embodiment, the shape of the first conductive part 4 based on the orthographic projection of the display area 1 may further include a first edge, a second edge and a third edge connected, and the sides of the first edge and the third edge far from the second edge are connected to the touch electrode 2. The second side can be in a straight line shape, a broken line shape, an arc shape, a wavy line shape or the like. The lengths of the first side and the third side in the second direction may be the same or different, and for convenience of production and manufacture, the lengths of the first side and the third side in the second direction in the embodiment of the present application are the same.
In an alternative embodiment, each of the touch electrodes 2 is distributed on the substrate 14 in an array, so that the spacers exist between two adjacent touch electrodes 2. Therefore, the plurality of touch electrodes 2 are arranged in a grid-like structure after the display area 1 is arranged. The spacing area between two adjacent touch electrodes 2 in the second direction is a separation gap 6. The separation gap 6 comprises a first gap 7, a second gap 8, a third gap 9 and a fourth gap 10 connected.
In a specific embodiment, the intervals between two adjacent touch electrodes are equal. In particular, said first gap 7 has a width D1The width of the second gap 8 is D2The width of the third gap 9 is D3The width of the fourth gap is D4Wherein D is1＝D2＝D3＝D4. By setting the widths of the respective portions of the separation gap 6 to be the same, the manufacturing of the manufacturing process is facilitated and the performance of the array substrate can be ensured. The width of the separation gap 6 should not be too small, and in order to ensure the performance of the array substrate, an arrangement space should be reserved between two adjacent touch electrodes 2 for the SD line and the TX line of the array substrate.
Referring to fig. 1 to 6, when a plurality of first conductive parts 4 and second conductive parts 5 are provided, the separation gaps 6 are formed in a plurality of sets in the second direction, and two adjacent separation gaps 6 are connected by the first gap 7 of one separation gap 6 and the fourth gap 10 of the other separation gap 6.
In a specific embodiment, a spacing area between two adjacent touch electrodes 2 in the first direction is a straight line section based on a shape of an orthogonal projection of the substrate 14. In the first direction, the first conductive part 4 and the second conductive part 5 are not disposed between two adjacent touch electrodes 2, and the boundary of the spacer between two adjacent touch electrodes 2 is the left and right sides of the touch electrode 2. Under the condition that the first grid line 3 is charged, the two opposite sides of the touch electrode 2 in the first direction have no charging difference rate, so that the cross striation problem is avoided. Therefore, the shapes of the touch electrodes 2 on both sides of the first direction can be arbitrarily set according to actual needs, which is not listed here.
In a specific embodiment, the first gate lines 3 are provided in plurality, and the first gate lines 3 are uniformly spaced in the second direction. Under the condition that the first grid lines 3 are charged, the difference rates of the edges of two adjacent touch electrodes 2 in the second direction when the first grid lines 3 are charged are mutually offset, and the occurrence probability of the cross striation problem is reduced.
In an alternative embodiment, the shortest distance between the side of the first conductive part 4 away from the touch electrode 2 and the first gate line 3 in the second direction is equal to the shortest distance between the side of the second conductive part 5 away from the touch electrode 2 and the first gate line 3 in the second direction.
