The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention. The following disclosure provides many different embodiments or examples for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize applications of other processes and/or uses of other materials.
Referring to fig. 1, the present invention provides a touch panel 200, in which the touch panel 200 includes a touch substrate 100 and an Integrated Circuit 110 (IC), and the IC 110 is connected to the touch substrate 100. The touch substrate 100 is used for receiving touch and forming a data signal. The integrated circuit 110 is used for processing data signals formed by the touch substrate 100.
Specifically, the outline of the touch substrate 100 may be rectangular, square, etc., and the specific shape of the touch substrate 100 is not limited herein. As shown in fig. 1, the touch substrate 100 is rectangular, and the integrated circuit 110 is disposed on one side of the touch substrate 100 in the longitudinal direction. The integrated circuit 110 may be connected to the touch substrate 100 through a flexible circuit board. Of course, the integrated circuit 110 may also be disposed on the touch substrate 100.
Referring to fig. 2 and 3, a touch substrate 100 according to an embodiment of the invention includes a plurality of first electrodes 10 arranged in parallel and a plurality of second electrodes 20 arranged in parallel. Each of the first electrodes 10 includes a plurality of first sub-electrodes 11 arranged at intervals along the first direction D1. The plurality of second electrodes 20 are disposed to cross the plurality of first electrodes 10, each of the second electrodes 20 includes a plurality of second sub-electrodes 21 arranged at intervals along a second direction D2, and the first direction D1 crosses the second direction D2.
Referring to fig. 4 and fig. 5, a distance between the adjacent first sub-electrode 11 and the second sub-electrode 21 away from the integrated circuit 110 is a first distance L1, a distance between the adjacent first sub-electrode 11 and the second sub-electrode 21 close to the integrated circuit 110 is a second distance L2, and the first distance L1 is smaller than the second distance L2.
In the touch substrate 100 of the embodiment of the invention, the distance between the adjacent first sub-electrode 11 and the adjacent second sub-electrode 21 away from the integrated circuit 110 is smaller than the distance between the adjacent first sub-electrode 11 and the adjacent second sub-electrode 21 close to the integrated circuit 110, so that the capacitance formed between the adjacent first sub-electrode 11 and the adjacent second sub-electrode 21 away from the integrated circuit 110 can be increased, the signal value formed between the adjacent first sub-electrode 11 and the adjacent second sub-electrode 21 away from the integrated circuit 110 is larger than the signal value formed between the adjacent first sub-electrode 11 and the adjacent second sub-electrode 21 close to the integrated circuit 110, and thus the loss caused by the impedance of the conductive connection line can be compensated, and the uniformity of the touch sensing operation at each part of the touch substrate 100 is better.
Specifically, one of the first electrode 10 and the second electrode 20 is a sensing electrode (Rx), and the other is a scanning electrode (Tx). For example, the first electrode 10 is a sensing electrode, and the second electrode 20 is a driving electrode. For another example, the first electrode 10 is a driving electrode and the second electrode 20 is a sensing electrode.
A capacitance may be formed between the adjacent first and second sub-electrodes 11 and 21. When an external object such as a finger touches a certain position of the touch substrate 100, the capacitance between the first sub-electrode 11 and the second sub-electrode 21 near the certain position changes. For example, an excitation signal may be sequentially applied to the first electrodes 10, the second sub-electrodes 21 adjacent to the first sub-electrode 11 in the excited first electrodes 10 may each receive a sensing signal, and the capacitance between the first sub-electrode 11 and the adjacent second sub-electrode 21 may be determined according to the sensing signal, so that the touch position may be identified.
It can be understood that, in the adjacent first sub-electrode 11 and the second sub-electrode 21, the capacitance between the first sub-electrode 11 and the second sub-electrode 21 is inversely proportional to the distance therebetween. In other words, the larger the distance between the first sub-electrode 11 and the second sub-electrode 21 is, the smaller the capacitance formed by the first sub-electrode 11 and the second sub-electrode 21 is, and vice versa. Therefore, in the embodiment of the invention, the distance between the first sub-electrode 11 and the second sub-electrode 21 which are far away from the integrated circuit 110 and adjacent to each other is larger, so that the value of the capacitance signal which can be formed is larger, so as to compensate the loss of the signal in the transmission process to the integrated circuit 110, and ensure the uniformity of the touch operation sensed at each part of the touch substrate 100.
In the embodiment of the present invention, the first electrode 10 and the second electrode 20 may be made of a metal mesh film layer. When the touch substrate 100 is used to manufacture the touch screen 200 with a touch function, because the first electrode 10 and the second electrode 20 are located in the image display area of the touch screen 200, in order to prevent the first electrode 10 and the second electrode 20 from affecting the display of an image, the first electrode 10 and the second electrode 20 need to be made of a transparent conductive material, for example, Indium Tin Oxide (ITO), which has good conductivity and transparency.
Of course, the first electrode 10 and the second electrode 20 may be formed using a conductive metal material, and the conductive metal material may be a metal having a low resistivity, such as silver or copper. The conductive metal material may form a film layer of a plurality of metal lines crossing in the transverse and longitudinal directions, the line width of the metal lines is small, usually in a micron order, for example, less than 5 microns, and the film layer is thin and invisible to naked eyes, the openings of the mesh may transmit light, and the touch substrate 100 made of the conductive metal material has good conductivity and light transmittance.
For example, in order to make the patterns of the first sub-electrodes 11 and the second sub-electrodes 21 as close as possible, so as to increase the detection range of the touchable point, in each of the first electrodes 10, except for the first sub-electrode 11 in the first electrode 10 and the first sub-electrode 11 in the last first electrode 10, the shapes of the remaining first sub-electrodes 11 are all rhombus. Similarly, in each of the second electrodes 20, except for the second sub-electrode 21 in the first second electrode 20 and the second sub-electrode 21 in the last second electrode 20, the shapes of the remaining second sub-electrodes 21 are rhombus.
Here, the expressions "the first electrode 10" and "the last first electrode 10" are used only to distinguish two first electrodes 10 on the two sides, which are the two most side, of the plurality of first electrodes 10, which are arranged in the second direction D2; similarly, the expressions "the first second electrode 20" and "the last second electrode 20" are only used to distinguish two second electrodes 20 at the two extreme sides arranged along the first direction D1 among the plurality of second electrodes 20.
The first direction D1 and the second direction D2 only need to have a certain included angle so that the first electrode 10 and the second electrode 20 are crossed. The included angle may be 90 degrees, i.e. the first direction D1 is a row direction, and the opposite second direction D2 is a column direction, so as to simplify the difficulty of arranging the electrodes.
In this embodiment, the distance between the adjacent first sub-electrode 11 and the second sub-electrode 21 refers to the minimum dimension between the edge of the first sub-electrode 11 and the edge of the opposite second sub-electrode 21 in the adjacent first sub-electrode 11 and the second sub-electrode 21.
In some embodiments, the distance between adjacent first sub-electrodes 11 and second sub-electrodes 21 increases in a direction closer to the integrated circuit 110. In this way, the capacitance signals formed by the first sub-electrode 11 and the second sub-electrode 21 which are far away from the integrated circuit 110 and adjacent to each other, and the capacitance signals formed by the first sub-electrode 11 and the second sub-electrode 21 which are near to the integrated circuit 110 and adjacent to each other, after reaching the integrated circuit 110, are substantially the same in magnitude, so that the touch uniformity of each part of the touch substrate 100 is better.
As in the orientation example of fig. 3, the integrated circuit 110 is disposed on the lower side of the touch substrate 100, and the distance between the adjacent first sub-electrode 11 and the second sub-electrode 21 increases along the top-to-bottom direction. Or, in the down-to-up direction, the distance between the adjacent first sub-electrodes 11 and second sub-electrodes 21 decreases.
In some embodiments, each first sub-electrode 11 in the same first electrode 10 is equidistant from the adjacent second electrode 20. In this way, the touch sensitivity of each portion of the touch substrate 100 in the same first direction D1 is substantially the same, and the layout difficulty of the electrodes can be reduced by such a design.
As shown in fig. 3, one first sub-electrode 11 is adjacent to four second sub-electrodes 21, and the distances between the four second sub-electrodes 21 and the first sub-electrode 11 are equal.
Referring to fig. 4, in some embodiments, in the adjacent first sub-electrode 11 and the second sub-electrode 21, the first sub-electrode 11 includes a first edge 12, the second sub-electrode 21 includes a second edge 22 opposite to the first edge 12, and the first edge 12 and the second edge 22 are in a complementary structure of concave-convex arrangement. Thus, the relative area of the first sub-electrode 11 and the second sub-electrode 21 is larger, which is beneficial to the larger capacitance formed by the first sub-electrode 11 and the second sub-electrode 21, so that the sensitivity of sensing of the touch substrate 100 can be improved.
The specific shape of the first edge 12 and the second edge 22 may be a rectangular concave-convex shape, or may be a curved concave-convex shape, and the specific shape of the first edge 12 and the second edge 22 is not limited herein.
In some embodiments, the first electrode 10 further comprises a first bridge electrode 13, and the first bridge electrode 13 connects two adjacent first sub-electrodes 11 located in the same first electrode 10. The second electrode 20 further comprises a second bridge electrode 23, and the second bridge electrode 23 connects two adjacent second sub-electrodes 21 in the same second electrode 20.
As such, the first bridge electrode 13 may electrically connect the adjacent two first sub-electrodes 11, and the second bridge electrode 23 may electrically connect the adjacent two second sub-electrodes 21. The first bridge electrode 13 and the first sub-electrode 11 may be of an integral structure. The second bridge electrode 23 and the second sub-electrode 21 may be of an integral structure.
It should be noted that the first bridge electrode 13 and the second bridge electrode 23 are insulated from each other, so that the first electrode 10 and the second electrode 20 can be prevented from short-circuiting and other undesirable phenomena.
In some embodiments, the first sub-electrode 11 and the second sub-electrode 21 are located at the same layer. For example, the material and thickness of the first sub-electrode 11 and the second sub-electrode 21 may be the same, and the first sub-electrode 11 and the second sub-electrode 21 may be formed through a one-step patterning process, so that the manufacturing process of the touch substrate 100 may be simpler and the manufacturing cost may be lower.
Referring to fig. 3 again, in some embodiments, the touch substrate 100 further includes a substrate 30, and the first electrode 10 and the second electrode 20 are disposed on the substrate 30. In this manner, the substrate 30 may allow the patterns of the first and second electrodes 10 and 20 to be easily formed. The substrate 30 serves as a basic layer structure of the touch substrate 100, so that the manufacturing process of the touch substrate 100 is easier to complete.
In some embodiments, the touch substrate 100 further includes a plurality of first connecting lines 40 and a plurality of second connecting lines 50, each first connecting line 40 is connected to a corresponding first electrode 10, each second connecting line 50 is connected to a corresponding second electrode 20, and both the first connecting lines 40 and the second connecting lines 50 are electrically connected to the integrated circuit 110.
In this manner, the integrated circuit 110 electrically connects the first electrode 10 and the second electrode 20, and the first connection line 40 and the second connection line 50 may enable both the first electrode 10 and the second electrode 20 to communicate with the integrated circuit 110. Specifically, both the first connection line 40 and the second connection line 50 may be conductive. The first connection line 40 and the second connection line 50 may be made of conductive material such as silver, gold, or indium tin oxide.
It should be noted that in the embodiment of fig. 3, one first connection line 40 is connected to one end of each first electrode 10, and one second connection line 50 is connected to one end of each second electrode 20. In other embodiments, one first connection line 40 may be connected to both ends of each first electrode 10, and/or one second connection line 50 may be connected to both ends of each second electrode 20.
Referring to fig. 6, the present invention further provides a display device 300, wherein the display device 300 includes the touch screen 200. The specific type of the display device 300 is not particularly limited, and the types of the display device 300 commonly used in the art may be any, specifically, such as a display screen, a mobile phone, a tablet computer, a wearable device, and the like, and those skilled in the art can select the display device according to the specific use requirement of the display device 300, and details thereof are not repeated herein.
