In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a display device according to an embodiment of the present invention. The present embodiment provides a display device 200 including: m touch electrodes 10, wherein the M touch electrodes 10 are used for sensing sliding operation; the touch electrode 10 is electrically connected to a touch signal port 20 of a signal processing unit (not shown); the touch signal port 20 comprises at least one common touch signal port 21, the common touch signal port 21 is electrically connected with the at least two touch electrodes 10, and the areas of the at least two touch electrodes 10 are different from each other; wherein M is a positive integer and M is more than or equal to 2. In the display device shown in fig. 2, only M is 2 as an example.
The display device shown in this embodiment has a display function, and for example, the display device includes a display panel for realizing the display function. For example, the display panel may be a liquid crystal display panel, an organic light emitting display panel, or an electronic paper display panel, and the specific structure of the display panel is not limited in this embodiment.
The display device includes 2 touch electrodes 10, namely a touch electrode 101 and a touch electrode 102, and it should be noted that, in the display device shown in fig. 2, only the shape of the touch electrode 10 is taken as a rectangle for illustration, and the specific shape of the touch electrode 10 is not limited in this embodiment.
The touch electrode 101 and the touch electrode 102 are electrically connected to the common touch signal port 21, and the touch electrode 101 and the touch electrode 102 have different areas and are used for sensing a sliding operation. In this embodiment, only the area of the touch electrode 101 is larger than the area of the touch electrode 102 is taken as an example for description, and optionally, the area of the touch electrode 101 may be smaller than the area of the touch electrode 102. Specifically, when a finger slides from the touch electrode 101 to the touch electrode 102, the touch signals sensed by the touch electrode 101 and the touch electrode 102 are different because the areas of the touch electrode 101 and the touch electrode 102 are different, for example, the signal value of the touch signal sensed by the touch electrode 101 is larger, and the signal value of the touch signal sensed by the touch electrode 102 is smaller. After receiving the touch signal of the touch electrode 101, the signal processing unit receives the touch signal of the touch electrode 102 within a preset time interval, and can determine that a sliding operation occurs on the display device, where the sliding direction is a direction from the touch electrode 101 to the touch electrode 102. After receiving the sliding operation instruction, the signal processing unit may cause the display device to perform a function corresponding to the sliding operation, for example, display corresponding image information.
It should be noted that the signal processing unit is used for processing the electrical signal of the touch electrode 10. Alternatively, the signal processing unit may be an Integrated Circuit (IC). The signal processing unit may be disposed in various positions, for example, the signal processing unit may be disposed in the display device; or, optionally, the display device includes a display panel, and the signal processing unit may be bound to the display panel, and the specific structure and the setting manner of the signal processing unit are not specifically limited in this embodiment.
The touch electrode 10 is electrically connected to the signal processing unit through the touch signal port 20. Optionally, the electrical signal sensed by the touch electrode 10 is transmitted to the touch signal port 20 through the touch electrode line 30, the touch signal port 20 is electrically connected to the signal processing unit, and the electrical signal sensed by the touch electrode 10 may be transmitted to the signal processing unit. The touch signal port 20 is used for electrically connecting the touch electrode line 30 and the signal processing unit. Optionally, the touch signal port 20 is a pad made of a conductive material, and when the signal processing unit is an integrated circuit chip, the integrated circuit chip may be directly bonded to the substrate on which the touch electrode 10 is located, so that the integrated circuit chip is electrically connected to the pad. Alternatively, a Flexible Printed Circuit (FPC for short) may be electrically connected to the pad, and the electrical signal sensed by the touch electrode 10 may be transmitted to the signal processing unit through the Flexible Printed Circuit.
The touch signal ports 20 include at least one common touch signal port 21, the number of the touch electrodes 10 electrically connected to the common touch signal port 21 is at least 2, and in fig. 2, only an embodiment in which 2 touch electrodes 10 are connected to the common touch signal port 21 is illustrated. Optionally, 3, 4 or more than 4 touch electrodes 10 may be electrically connected to one common touch signal port 21. The areas of the touch electrodes 10 connected to the same common touch signal port 21 are different from each other. The areas of the touch electrodes 10 may affect the sensed electrical signals to be different, and the areas of the touch electrodes 10 connected to the same common touch signal port 21 are set to be different from each other, so that the signal processing unit may distinguish the electrical signals sensed by different touch electrodes 10, thereby recognizing the sliding operation.
In this embodiment, the number of the touch electrodes 10 is two, the number of the touch signal ports 20 is only one, and the number of the touch signal ports 20 is smaller than the number of the touch electrodes 10, so that the function of identifying the sliding operation can be realized without separately providing the touch signal ports 20 for each touch electrode 10. Due to the display device provided by the embodiment, the number of the touch signal ports 20 is reduced, and an additional signal processing unit for processing the electric signal of the touch electrode 10 is not required.
It should be noted that the display device provided in this embodiment may be a display product of a terminal, such as a mobile phone, a tablet computer, and the like; or a module for assembling a display product, such as a display module with touch electrodes.
In the display device provided by the invention, the touch signal ports of the signal processing unit comprise at least one common touch signal port, the common touch signal port is electrically connected with at least two touch electrodes, and the areas of the at least two touch electrodes are different from each other. In the technical scheme provided by the embodiment of the invention, each touch electrode is not required to be provided with a corresponding touch signal port independently, so that the number of the touch signal ports in the signal processing unit can be reduced, a chip for processing an electric signal of the touch electrode is not required to be additionally arranged, the process for manufacturing the display device is reduced, and the cost of the display device is reduced. Meanwhile, different signal quantities of the touch signals can be caused by different areas of the touch electrodes, when the sliding operation occurs, at least two touch electrodes electrically connected with the common touch signal port respectively generate different touch signals, and the signal processing unit can identify the sliding operation according to the size and the generation sequence of the touch signals.
In some optional embodiments, please refer to fig. 3, and fig. 3 is a schematic structural diagram of another display device provided in the embodiments of the present invention. The reference numerals of fig. 2 are used along with fig. 3, and the description of the same parts is omitted. In the display device 300 provided in this embodiment, the common touch signal port 21 is electrically connected to two adjacent touch electrodes 10, and the areas of the two adjacent touch electrodes 10 are Sx and Sy, respectively, where Sx is greater than or equal to 10% Sy and is less than or equal to 40% Sy. In the display device provided in this embodiment, the number of the touch electrodes 10 electrically connected to the common touch signal port 21 is two, and the two touch electrodes 10 are adjacent to each other without any other touch electrode therebetween. The two adjacent touch electrodes 10 are respectively a touch electrode 103 and a touch electrode 104, wherein the area of the touch electrode 103 is Sy, the area of the touch electrode 104 is Sx, and Sx is less than or equal to 10% Sy and less than or equal to 40% Sy; or the area of the touch electrode 104 is Sy, the area of the touch electrode 103 is Sx, and 10% Sy is less than or equal to Sx and less than or equal to 40% Sy. Optionally, Sy 30mm2。
In the present embodiment, only the area of the touch electrode 103 is Sy and the area of the touch electrode 104 is Sx are taken as examples for explanation, when an object such as a finger slides, the finger covers the area where the touch electrode 10 is located, the coverage area between the object such as the finger and the touch electrode 103, that is, the facing area between the touch electrode 103 and the object such as the finger is constantly changed, and normally, when the object such as the finger slides from the touch electrode 103 to the touch electrode 104, the coverage area between the object such as the finger and the touch electrode 103 gradually decreases. When the coverage area of the object such as the finger and the touch electrode 103 is greater than 60% Sy, the signal processing unit may identify that the object such as the finger is touched at the position corresponding to the touch electrode 103 according to the electrical signal sensed by the touch electrode 103; when the coverage area of the object such as the finger and the touch electrode 103 is less than or equal to 60% Sy, the signal processing unit identifies that the object such as the finger does not touch the position corresponding to the touch electrode 103 according to the electrical signal sensed by the touch electrode 103, and at this time, the touch electrode 103 does not "report a point".
In this embodiment, the area Sx of the touch electrode 104 is set to be between 10% Sy and 40% Sy, and when the common touch signal port 21 receives an electrical signal corresponding to a coverage area greater than 60% Sy, the signal processing unit determines that an object such as a finger is touched at a position corresponding to the touch electrode 103; when the common touch signal port 21 receives the electrical signal corresponding to the coverage area of 10% Sy to 40% Sy, the signal processing unit determines that an object such as a finger is touched at the position corresponding to the touch electrode 104. Since the arrangement of the touch electrodes 103 and 104 is directional, the signal processing unit can recognize whether an object such as a finger performs a sliding operation. The area Sx of the touch electrode 104 should not be too small, and when the area Sx is smaller than 10% Sy, the sensed electrical signal is too small, which is not beneficial for the signal processing unit to process the electrical signal.
In some optional embodiments, please refer to fig. 4, and fig. 4 is a schematic structural diagram of another display device provided in the embodiments of the present invention. Fig. 4 follows the reference numerals of fig. 2, and the description of the same parts is omitted. In the display device 400 provided in this embodiment, the common touch signal port is electrically connected to two non-adjacent touch electrodes, and the areas of the two non-adjacent touch electrodes are Sz and Sw, where Sz is greater than or equal to 10% and less than or equal to 90% and Sw, respectively. In the display device provided in this embodiment, the number of the touch electrodes 10 electrically connected to the common touch signal port 21 is two, and the two touch electrodes 10 are not adjacent to each other and other touch electrodes are disposed therebetween. The two non-adjacent touch electrodes 10 are respectively a touch electrode 105 and a touch electrode 106, wherein the area of the touch electrode 105 is Sw, the area of the touch electrode 106 is Sz, and 10% sws is less than or equal to Sz and less than or equal to 90% sws; or the area of the touch electrode 106 is Sw, the area of the touch electrode 105 is Sz, and 10% Sw is less than or equal to Sz and less than or equal to 90% Sw. Optionally, Sw 30mm2。
In this embodiment, only the area of the touch electrode 105 is Sw and the area of the touch electrode 106 is Sz are taken as an example for explanation, when an object such as a finger performs a sliding operation, the object such as the finger successively passes through the areas where the touch electrode 105 and the touch electrode 106 are located, the electrical signals sensed by the touch electrode 105 and the touch electrode 106 are sequentially transmitted to the common touch signal port 21, and the signal processing unit performs analysis to identify the sliding operation of the object such as the finger.
Since the touch electrode 105 and the touch electrode 106 are not adjacent to each other, and other touch electrodes are disposed between the touch electrode 105 and the touch electrode 106, electrical signals sensed by the other touch electrodes are also transmitted to the signal processing unit, and the signal processing unit can identify the sliding operation by combining the electrical signals of the plurality of touch electrodes. Specifically, for example, in the display device shown in fig. 4, at least the touch electrode 107 is further disposed between the touch electrode 105 and the touch electrode 106, the area of the touch electrode 105 is Sw, and the area of the touch electrode 106 is any value from 10% Sw to 90% Sw. When an object such as a finger slides through the touch electrode 105, the touch electrode 107 and the touch electrode 106 in sequence, and the common touch signal port 21 receives an electric signal corresponding to the coverage area of Sw, the signal processing unit determines that the object such as the finger is touched at a position corresponding to the touch electrode 105; since the touch electrode 107 can be electrically connected to one touch signal port 20, the signal processing unit receives the electrical signal sensed by the touch electrode 107, and determines that an object such as a finger is touched at a position corresponding to the touch electrode 107; then, when the common touch signal port 21 receives the electrical signal corresponding to the coverage area of 10% Sw to 90% Sw, the signal processing unit may determine that an object such as a finger is touched at the position corresponding to the touch electrode 105. Since the arrangement of the touch electrodes 105, 107, and 106 is directional, the signal processing unit can recognize whether an object such as a finger performs a sliding operation. The area Sz of the touch electrode 106 is not too small, and when the area Sz is less than 10% Sw, the sensed electrical signal is too small, which is not beneficial for the signal processing unit to process the electrical signal. The area Sz of the touch electrode 106 should not be too large, and when the area Sz is larger than 90% Sw, the areas of the touch electrode 106 and the touch electrode 105 are very close to each other, and accordingly, the signal values of the touch signals generated by the touch electrode 106 and the touch electrode 105 are very close to each other. When an object such as a finger touches the touch electrode 10, the electrical signal sensed by the touch electrode 10 has some interference, and the electrical signal generated by the interference is equivalent to the electrical signal of the touch electrode with an area of 5% Sw. When the signal values of the touch signals of the touch electrodes 106 and 105 are very close, the signal processing unit may not be able to effectively distinguish the touch signals of the touch electrodes 106 and 105, thereby reducing the accuracy of identifying the sliding operation.
In some optional embodiments, please refer to fig. 5, and fig. 5 is a schematic structural diagram of another display device according to an embodiment of the present invention. In the display device 500 provided in this embodiment, the touch signal ports include two common touch signal ports 21, which are a first common touch signal port 211 and a second common touch signal port 212, respectively; the M touch electrodes 10 include a first touch electrode 11, a first sub-touch electrode 111, a second touch electrode 12, and a second sub-touch electrode 122 sequentially arranged along the first sliding direction x 1. In this embodiment, the first touch electrode 11, the first sub-touch electrode 111, the second touch electrode 12, and the second sub-touch electrode 122 are disposed for sensing a sliding operation. There are various specific electrical connection methods between the touch electrode and the common touch signal port. In the following, embodiments of the present invention provide a description of a specific electrical connection manner between a touch electrode and a common touch signal port.
In some optional embodiments, with continued reference to fig. 5, the first touch electrode 11 and the first sub-touch electrode 111 are electrically connected to the first common touch signal port 211; the second touch electrode 12 and the second sub-touch electrode 122 are electrically connected to the second common touch signal port 212.
In this embodiment, the first touch electrode 11 and the first sub-touch electrode 111 are adjacent to each other and electrically connected to the same first common touch signal port 211, so the areas of the first touch electrode 11 and the first sub-touch electrode 111 may be Sx and Sy, respectively, and Sx is greater than or equal to 10% Sy and less than or equal to 40% Sy. Fig. 5 only illustrates a technical solution that the area of the first touch electrode 11 is larger than the area of the first sub-touch electrode 111, and in other alternative embodiments, the area of the first sub-touch electrode 111 may be larger than the area of the first touch electrode 11.
The second touch electrode 12 and the second sub-touch electrode 122 are adjacent to each other and electrically connected to the same second common touch signal port 212, so the areas of the second touch electrode 12 and the second sub-touch electrode 122 can be Sz and Sw, and 10% Sw ≦ Sz ≦ 90% Sw, respectively. Fig. 5 only illustrates a technical solution that the area of the second touch electrode 12 is larger than the area of the second sub-touch electrode 122, and in other alternative embodiments, the area of the second sub-touch electrode 122 may be larger than the area of the second touch electrode 12.
Specifically, for example, when a finger slides along the first sliding direction x1 to pass through the first touch electrode 11, the first sub-touch electrode 111, the second touch electrode 12 and the second sub-touch electrode 122 in sequence, the signal processing unit first receives the electrical signal of the first touch electrode 11 and the electrical signal of the first sub-touch electrode 111 through the first common touch signal port 211 in sequence, and then the signal processing unit receives the electrical signal of the second touch electrode 12 and the electrical signal of the second sub-touch electrode 122 through the second common touch signal port 212 in sequence, so that the signal processing unit can recognize the sliding operation of the finger by accordingly recognizing that the finger slides along the first sliding direction x1 to pass through the first touch electrode 11, the first sub-touch electrode 111, the second touch electrode 12 and the second sub-touch electrode 122 in sequence, that is to identify the spatial sequence by using the common touch signal port and the touch electrode area at the same time, thereby recognizing the sliding operation of the finger.
It is understood that the signal processing unit may also recognize the sliding operation of the finger when the finger is slid in the direction opposite to the first sliding direction x 1.
In addition, the first touch electrode 11 and the first sub-touch electrode 111 may share one touch electrode line 30, and the second touch electrode 12 and the second sub-touch electrode 122 may share one touch electrode line 30, so that the display device provided in this embodiment may further reduce the number of touch electrode lines 30, which is beneficial to reducing the routing of the display device.
In some alternative embodiments, please refer to fig. 6, and fig. 6 follows the reference numerals of fig. 5, and the description of the same parts is omitted.
