Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present invention, and fig. 2 is a schematic structural diagram related to a touch switch in fig. 1. Referring to fig. 1 and 2, the display panel 10 includes a display area 10A and a non-display area 10N surrounding the display area 10A, the display area 10A includes a plurality of display scan lines 101 extending in a first direction X and a plurality of display data lines 102 extending in a second direction Y, the plurality of display scan lines 101 and the plurality of display data lines 102 are insulated and crossed to define a plurality of pixel units 103, and the first direction X and the second direction Y are crossed; the display area 10A further includes a plurality of touch scan lines 104, a plurality of touch data lines 105, a plurality of touch electrodes 106 arranged in an array, and a touch switch 107 corresponding to each touch electrode 106, where the touch switch 107 includes a touch signal input end 1071, a touch signal output end 1072, and a touch control end 1073; each touch scanning line 104 is electrically connected to the touch control terminals 1073 of the touch switches 107 corresponding to the same row of touch electrodes 106; at least one touch data line 105 is electrically connected with the touch signal input ends 1071 of the touch switches 107 corresponding to the same row of touch electrodes 106; a touch signal output end 1072 of the touch switch 107 is electrically connected to the touch electrode 106; in the plurality of touch switches 107 and the plurality of display scan lines 101 corresponding to the same row of touch electrodes 106, distances between the touch control terminals 1073 of at least two touch switches 107 and the same display scan line 101 are different.
The plurality of pixel units 103 defined by the display scanning lines 101 and the display data lines 102 in the display area 10A in an insulating and intersecting manner may be arranged in an array, and the light emitting colors of the plurality of pixel units 103 are different, for example, the light emitting colors of the pixel units 103 may include red, green, and blue, and may further include yellow, orange, and white, so as to normally display a white picture or a color picture, and at the same time, meet different display requirements of the display panel 10. It should be noted that the light emitting color of the pixel unit 103 may also be other colors known to those skilled in the art, and may be set according to the actual requirement of the display panel 10, which is not limited in the embodiment of the present invention.
The touch signal transmission process of the display panel 10 is similar to the display signal transmission process, specifically: the touch scan line 104 controls on/off of a touch switch 107 electrically connected thereto, and when the touch switch 107 is turned on, the touch data line 105 provides a touch signal to a touch electrode 106 electrically connected to the touch switch 107 through the touch switch 107. For example, for the self-contained touch method, the digital control data line 105 may also transmit a touch sensing signal to a signal processing circuit (for example, the signal processing circuit may be a driving IC written below).
For example, taking the touch electrodes 106 arranged in an array of M rows and N columns as an example, the touch control end 1073 of the touch switch 107 corresponding to each row of touch electrodes 106 is electrically connected to the same touch scan line 104, and M touch scan lines 104 need to be provided; the touch signal input end 1071 of the touch switch 107 corresponding to each row of touch electrodes 106 is electrically connected to at least one touch data line 105, so as to ensure that the number of touch data lines 105 is small, which is beneficial to the narrow frame design of the display panel 10.
On the basis of the above structure, by setting the plurality of touch switches 107 and the plurality of display scan lines 101 corresponding to the same row of touch electrodes 106, distances between the touch control ends 1073 of at least two touch switches 107 and the same display scan line 101 are different, so that the plurality of touch switches 107 corresponding to the same row of touch electrodes 106 are staggered, and a whole row of touch switches 107 is not formed and thus, a visually-visible display effect difference in the row direction (i.e., the first direction X) is favorably avoided.
For example, taking the first row of touch electrodes 106 in fig. 2 as an example, the first row of touch electrodes 106 includes 3 touch electrodes 106, and each touch electrode 106 is provided with 1 touch switch 107. Taking the orientation shown in fig. 2 as an example, from left to right, the distances from the touch control end 1073 of the touch switch 107 corresponding to each touch electrode 106 to the same display scan line 101 (for example, the third display scan line 101 from top to bottom is taken as an example) are sequentially the first distance L11, the second distance L12, and the third distance L13, and the magnitude relationship of the three distances is: l12> L13> L11, that is, the distances are different from each other, and therefore, the arrangement of the touch switches 107 in the row direction is staggered from each other, and the arrangement does not constitute a full row arrangement. Thereby contributing to reducing the difference in the display effect of the pixel units 103 in the row direction, and thus the picture display effect of the display panel 10 can be improved.
Fig. 3 is a schematic structural diagram of another display panel according to an embodiment of the present invention. Referring to fig. 3, the display related structure in the display panel 10 can be understood with reference to fig. 1, and the same points of the touch related structure as those in fig. 1 are not repeated, but different points are: in the display panel 10, the touch switches are arranged at different distances in the row direction (i.e., the second direction Y), and specifically, in the plurality of touch switches 107 and the plurality of display data lines 102 corresponding to the same row of touch electrodes 106, the distances between the touch signal input ends 1071 of at least two touch switches 107 and the same display data line 102 are different.
With such an arrangement, the touch switches 107 corresponding to the same row of touch electrodes 106 are staggered, and an entire row of touch switches 107 is not formed, thereby being beneficial to avoiding the difference of visually-visible display effects in the row direction.
For example, taking the third row of touch electrodes 106 in fig. 3 as an example, the third row of touch electrodes 106 includes 6 touch electrodes 106, and each touch electrode 106 is provided with a touch switch 107. Taking the orientation shown in fig. 3 as an example, the distances from the touch signal input end 1071 of the touch switch 107 corresponding to each touch electrode 106 to the same display data line 102 (for example, the sixth display data line 102 from right to left is taken as an example) are sequentially the fourth distance L21, the fifth distance L22, the sixth distance L23, the seventh distance L24, the eighth distance L25 and the ninth distance L26, and the magnitude relationship of the six distances is: l25> L24> L26> L21> L23> L22, that is, the distances are different from each other, and therefore, the arrangement of the touch switches 107 in the column direction is staggered from each other, and the arrangement does not form a whole column arrangement. Thereby contributing to reducing the difference in the display effect of the pixel units 103 in the column direction, and thus the picture display effect of the display panel 10 can be improved.
Fig. 4 is a schematic structural diagram of another display panel according to an embodiment of the present invention. In the display panel 10, in the plurality of touch switches 107 and the plurality of display scan lines 101 corresponding to the same row of touch electrodes 106, distances between the touch control terminals 1073 of at least two touch switches 107 and the same display scan line 101 are different from each other in the display panel structure shown in fig. 4, which is understood with reference to fig. 2 and 3; and in the plurality of touch switches 107 and the plurality of display data lines 102 corresponding to the same row of touch electrodes 106, distances between the touch signal input ends 1071 of at least two touch switches 107 and the same display data line 102 are different.
With such an arrangement, the touch switches 107 corresponding to the same row of touch electrodes 106 can be staggered, and the touch switches 107 in a whole row are not arranged, so that the difference of visually-visible display effects in the row direction can be avoided; the touch switches 107 corresponding to the same row of touch electrodes 106 can be staggered, and a whole row of touch switches 107 is not formed, so that the difference of visual and visible display effects in the row direction can be avoided; thereby, the picture display effect of the display panel 10 can be improved.
It should be noted that fig. 2-4 only exemplarily show that distances between the touch control ends 1073 of the touch switches 107 corresponding to the touch electrodes 106 in the same row and the same display scan line 101 are different, and/or distances between the touch signal input ends 1071 of the touch switches 107 corresponding to the touch electrodes 106 in the same column and the same display data line 102 are different, so that the arrangement of the touch switches 107 in the entire display panel 10 can be ensured to be greatly disturbed, and the display panel 10 can be ensured to have a better image display effect, but the display panel 10 provided by the embodiment of the present invention is not limited. In other embodiments, at least two of the distances in the row direction and the column direction may be set to be different according to the actual requirement of the display panel 10, and on the premise that the distances are partially the same, the embodiment of the present invention does not limit this.
Optionally, fig. 5 is a schematic structural diagram of another display panel provided in an embodiment of the present invention. Referring to fig. 1 and 5, each touch scan line 104 includes a touch scan main line 1041 and a plurality of touch scan branch lines 1042, and the touch control end 1073 of the touch switch 107 is connected to the touch scan main line 1041 through the touch scan branch lines 1042; the touch scanning main line 1041 is located between two adjacent rows of touch electrodes 106 and extends along the first direction X, and the touch scanning branch line 1042 is located between two adjacent rows of pixel units 103 and extends along the second direction Y; and/or, each touch data line 105 includes a touch data main line 1051 and a plurality of touch data branch lines 1052, and the touch input end 1071 of the touch switch 107 is connected to the touch data main line 1051 through the touch data branch lines 1052; the touch data main line 1051 is located between two adjacent columns of pixel units 103 and extends along the second direction Y, and the touch data branch line 1052 is located between two adjacent rows of pixel units 103 and extends along the first direction.
In this way, the touch scanning main line 1041 is a straight line, and the touch control terminal 1073 of the touch switch 107 is electrically connected to the touch scanning main line 1041 through the touch scanning branch line 1042; and/or, the touch data main line 1051 can be a straight line, and the touch signal input end 1071 of the touch switch 107 is electrically connected to the touch data main line 1042 through the touch data branch line 1052. Thus, the design difficulty and the manufacturing difficulty can be reduced.
In addition, the touch scan main line 1041, the touch scan branch line 1042, the touch data main line 1051, and the touch data branch line 1052 are not overlapped with the pixel units 103, i.e. the arrangement of the touch traces (including the touch scan line 104 and the touch data line 105) does not affect the arrangement of the pixel units 103 in the display panel 10, so the aperture ratio of the display panel 10 is not affected.
It should be noted that, fig. 5 only shows that each touch scan line 104 includes three touch scan branch lines 1042 and each touch data line 105 includes six touch data branch lines 1052 by way of example, but the present invention is not limited to the display panel 10. In other embodiments, the number of the touch scan branch lines 1042 in each touch scan line 104 and the number of the touch data branch lines 1052 in each touch data line 105 can be set according to the actual requirement of the display panel 10 and the arrangement of the touch electrodes 106 and the touch switches 107, which is not limited in the embodiment of the invention.
In addition, fig. 1 and fig. 5 only exemplarily show a design manner in which the touch scan line 104 and the touch data line 105 adopt a main line and a branch line, but do not limit the display panel 10 provided in the embodiment of the present invention. In other embodiments, the touch scan lines 104 and the touch data lines 105 may be arranged as a polygonal line or a curved line according to actual requirements of the display panel 10, which is not limited in the embodiments of the invention.
Optionally, the touch data main line 1051 may also be disposed between two adjacent rows of the touch electrodes 106 and arranged along the second direction Y, and in this structure, the touch electrodes 106 may be disposed in a space defined by the touch data main line 1051 and the touch scanning main line 1041 in an insulated and crossed manner, so that mutual interference among electrical signals in the touch electrodes 106, the touch data main line 1051 and the touch scanning main line 1041 is small, which is beneficial to improving touch accuracy and touch precision of the display panel 10.
It should be noted that fig. 1 and fig. 5 only exemplarily show the positions of the touch scan main line 1041 and the touch data main line 1051, but do not limit the display panel 10 according to the embodiment of the present invention. In other embodiments, the positions of the touch scanning main line 1041 and the touch data main line 1051 may be set according to the actual requirement of the display panel 10; and setting the touch scanning branch lines 1042 and the touch data branch lines 1042 according to the relative position relationship between the touch scanning main line 1041, the touch data main line 1051 and the touch switch 107, which is not limited in the embodiment of the present invention.
Optionally, fig. 6 is a schematic structural diagram of another display panel according to an embodiment of the present invention. Referring to fig. 6, each touch scan line 104 includes X (for example, X is 3 in fig. 6) touch scan branch lines 1042 (for example, illustrated as a first touch scan branch line 10421, a second touch scan branch line 10422 and a third touch scan branch line 10423 in fig. 6), and the length of the X-th touch scan branch line is L1 along the second direction Yx(illustratively, the length of the first touch scan branch line L1 in fig. 6 is set as the length of the first touch scan branch line L1, respectively1Length of second touch scanning branch line L12And third touch scan branch line length L13Shown); wherein, L1x＜L1x+1Or L1x＞L1x+1(ii) a X is more than or equal to 1 and less than or equal to X-1, wherein X is a positive integer, and X is more than or equal to 2 and is a positive integer.
For example, the length and size relationships of the three touch scan branch lines 1042 shown in fig. 6 are as follows: l11<L12<L13。
With such an arrangement, the lengths of the touch scan branch lines 1042 in the same touch scan line 104 can be sequentially increased or decreased, so as to facilitate reducing the design difficulty and the manufacturing difficulty of the touch scan line 104, and further reduce the design difficulty and the manufacturing cost of the entire display panel 10.
It should be noted that, in fig. 6, only three touch electrodes 106 corresponding to the same row are exemplarily shown that each touch scan line 104 includes three touch scan branch lines 1042, but the present invention is not limited to the display panel 10 provided in the embodiment of the present invention. In other embodiments, the number of the touch scan branch lines 1042 included in the touch scan line 104 can be set according to actual requirements of the display panel 10, which is not limited in the embodiments of the present invention.
Optionally, fig. 7 is a schematic structural diagram of another display panel according to an embodiment of the present invention. Referring to fig. 7, each touch data line 105 includes Y (for example, Y is 6 in fig. 7) touch data branch lines 1052 (for example, shown in fig. 7 as a first touch data branch line 10521, a second touch data branch line 10522, a third touch data branch line 10523, a fourth touch data branch line 10524, a fifth touch data branch line 10525, and a sixth touch data branch line 10526, respectively), and the length of the Y-th touch scan branch line is L2 along the first direction Xy(illustratively, the length of the first touch data branch line L2 in fig. 7 is used for each1Length of second touch data branch line L22Length of third touch data branch line L23Length of fourth touch data branch line L24Length of fifth touch data branch line L25And sixth touch data branch length L26Shown); wherein, L2y＜L2y+1Or L2y＞L2y+1(ii) a Y is more than or equal to 1 and less than or equal to Y-1, and Y is a positive integer, and Y is more than or equal to 2 and is a positive integer.
For example, the length and size relationship of the six touch data branches 1052 shown in fig. 7 is as follows:
L21<L22<L23<L24；L25>L26。
with such an arrangement, the lengths of the multiple touch data branch lines 1052 in the same touch data line 105 can be sequentially increased or decreased in a certain area, so as to facilitate reducing the design difficulty and the manufacturing difficulty of the touch data line 105, and further reduce the design difficulty and the manufacturing cost of the entire display panel 10.
Optionally, the lengths of all touch data branch lines 1052 in the same touch data line 105 may be sequentially increased or sequentially decreased, so as to reduce the design difficulty and the manufacturing difficulty of the touch data line 105, and thus reduce the design difficulty and the manufacturing cost of the entire display panel 10.
It should be noted that fig. 7 only shows that each touch data line 105 includes six touch data branch lines 1052 corresponding to six touch electrodes 106 in the same column by way of example, but the present invention is not limited to the display panel 10 provided in the embodiment of the present invention. In other embodiments, the number of the touch data branch lines 1052 included in the touch data lines 105 may be set according to actual requirements of the display panel 10, which is not limited in the embodiments of the present invention.
