Detailed Description

Embodiments of the present disclosure will be described below with reference to the accompanying drawings. In the drawings, the same reference numbers indicate the same or similar elements or process flows.

FIG. 1 is a simplified functional block diagram of an electronic device 100 according to an embodiment of the present disclosure. The electronic device 100 has a mutual capacitance touch function, and includes a plurality of first touch electrodes 110_1 to 110_5, a plurality of second touch electrodes 120_1 to 120_4, a control circuit 130, and a substrate SB. The first touch electrodes 110_1 to 110_5 are parallel to the Y axis and are sequentially arranged in the X axis direction. The second touch electrodes 120_1 to 120_4 are parallel to the X axis and are sequentially arranged in the Y axis direction, wherein the X axis is substantially orthogonal to the Y axis. The first touch electrodes 110_1 to 110_5 and the second touch electrodes 120_1 to 120_4 are staggered with each other, that is, each of the first touch electrodes 110_1 to 110_5 crosses the second touch electrodes 120_1 to 120_4, and each of the second touch electrodes 120_1 to 120_4 also crosses the first touch electrodes 110_1 to 110_ 5.

The control circuit 130 is used for respectively transmitting a plurality of scan signals Tx 1-Tx 5 to the first touch electrodes 110_ 1-110 _5 and respectively receiving a plurality of sensing signals Rx 1-Rx 4 from the second touch electrodes 120_ 1-120 _ 4. When a touch input (e.g., a user's finger or a stylus) approaches the electronic device 100, Mutual Capacitance values (Mutual capacitances) between the first touch electrodes 110_ 1-110 _5 and the second touch electrodes 120_ 1-120 _4 are changed, and the magnitudes of the sensing signals Rx 1-Rx 4 reflect the changes of the Mutual Capacitance values. Therefore, the control circuit 130 can calculate the positions of the touch inputs on the X axis and the Y axis according to the sensing signals Rx 1-Rx 4.

In some embodiments, the electronic device 100 further includes various elements for implementing the display function, such as one or more of the scan driving circuit, the backlight module and the pixel circuits, which are not shown in fig. 1 for simplicity. When the electronic device 100 is viewed from above in a direction of a Z-axis, the first touch electrodes 110_1 to 110_5, the second touch electrodes 120_1 to 120_4 and the plurality of pixel circuits are located in an active area AA above the substrate SB, wherein the Z-axis is substantially orthogonal to the X-axis and the Y-axis. The active area AA may be an area of the electronic device 100 for providing a display to a user, and the other area of the substrate SB surrounding the active area AA is a peripheral area PA. The peripheral area PA may be used for configuring the scan driving circuit to provide a control signal required by the pixel circuit to operate, and related technologies of the scan driving circuit are well known to those skilled in the art, and for brevity, are not described herein again.

In some embodiments, the electronic device 100 may be a smart phone, a tablet computer, or a notebook computer, and may also be an embedded touch display panel disposed in the aforementioned device.

It is noted that the number of the first touch electrodes 110_1 to 110_5 and the second touch electrodes 120_1 to 120_4 in fig. 1 is only an exemplary embodiment. In some embodiments, the number of the first touch electrodes and the second touch electrodes can be adjusted according to actual design requirements to adapt to panels with different sizes or to adapt to different resolution requirements.

In the embodiment of fig. 1, the control circuit 130 is disposed outside the substrate SB and can be connected to the substrate SB by a Chip On Film (COF) technology, but the disclosure is not limited thereto. In other embodiments, the control circuit 130 may also be disposed directly on the substrate SB by using a Chip On Glass (COG) technique.

Referring to fig. 1 again, each of the first touch electrodes 110_1 to 110_5 includes a plurality of first electrode blocks 112 and a plurality of bridge patterns 114. The plurality of first electrode blocks 112 are connected in series with the plurality of bridge patterns 114, that is, two adjacent first electrode blocks 112 are coupled to each other through one bridge pattern 114. Each of the second touch electrodes 120_1 to 120_4 includes a plurality of second electrode blocks 122 and a plurality of connection patterns 124. The plurality of second electrode blocks 122 are connected in series with the plurality of connection patterns 124, that is, two adjacent second electrode blocks 122 are coupled to each other through one connection pattern 124. Each bridging pattern 114 crosses a corresponding connecting pattern 124 in the Z-axis direction, and the first electrode block 112, the second electrode block 122 and the connecting pattern 124 are disposed on the same layer on the substrate SB, while the bridging patterns 114 are disposed on another different layer on the substrate SB. In fig. 2 described later, the region 140 in fig. 1 will be enlarged to explain the above-described laminated relationship in detail.

Each of the first electrode blocks 112 and each of the second electrode blocks 122 are substantially rectangular or diamond-shaped, but the disclosure is not limited thereto. In some embodiments, the first electrode blocks 112 at two ends (e.g., the head end and the tail end) of each of the first touch electrodes 110_1 to 110_5 can be substantially triangular, and the second electrode blocks 122 at two ends (e.g., the head end and the tail end) of each of the second touch electrodes 120_1 to 120_4 can also be substantially triangular. In other embodiments, the first electrode blocks 112 and the second electrode blocks 122 are electrically isolated from each other. In still other embodiments, the plurality of first electrode blocks 112 and the plurality of second electrode blocks 122 may be implemented by various suitable transparent conductive films, such as Indium Tin Oxide (ITO) films or aluminum zinc Oxide (Al-doped Zno).

In the embodiment of fig. 1, the electronic device 100 further includes a plurality of signal transmission patterns 150. Each of the first touch electrodes 110_1 to 110_5 is coupled to the signal transmission pattern 150 through the first electrode block 112 at the end thereof, and receives one of the scan signals Tx1 to Tx5 through the signal transmission pattern 150. Each of the second touch electrodes 120_1 to 120_4 can be coupled to the signal transmission pattern 150 through a corresponding second electrode block 122, and can transmit one of the sensing signals Rx1 to Rx5 through the signal transmission pattern 150. For example, the second touch electrode 120_1 is coupled to the signal transmission pattern 150 through a second electrode block 122 counted from the right side of fig. 1. For another example, the second touch electrode 120_2 is coupled to the signal transmission pattern 150 through a third second electrode block 122 counted from the right side of fig. 1, and so on. However, the connection manner of the second touch electrodes 120_1 to 120_4 and the signal transmission pattern 150 is not limited to the above. In some embodiments, each of the second touch electrodes 120_1 to 120_4 can also be coupled to the signal transmission pattern 150 through the second electrode block 122 at the head end or the tail end thereof. In fig. 5, the area 160 of fig. 1 is enlarged to further illustrate the manner in which the first touch electrodes 110_1 to 110_5 and the second touch electrodes 120_1 to 120_4 are electrically connected to the signal transmission pattern 150.

Fig. 2 is an enlarged schematic view of the area 140 in fig. 1. In some embodiments, the plurality of pixel circuits PX are used for receiving one or more voltages required for operation from the first touch electrodes 110_ 1-110 _5 and the second touch electrodes 120_ 1-120 _ 4. Therefore, at least one edge of the first electrode block 112 is saw-toothed, and at least one edge of the second electrode block 122 is also saw-toothed, so as to project the pixel circuits PX. Symbols R, G and B in each block of pixel circuits PX in fig. 2 represent that the pixel circuits PX emit red light, green light, and blue light, respectively, but the color arrangement and combination of the pixel circuits PX of the present disclosure are not limited thereto.

In detail, on the plane of the X-axis and the Y-axis, at least one edge of the first electrode block 112 includes a plurality of first protrusions 210, and at least one edge of the second electrode block 122 includes a plurality of second protrusions 220. Each of these first protruding portions 210 and second protruding portions 220 overlaps the projection of the corresponding one or more pixel circuits PX in the Z-axis direction.

In addition, in some embodiments, the gaps between the plurality of first electrode blocks 112 and the plurality of second electrode blocks 122 do not overlap with the projection of the pixel circuits PX in the direction of the Z-axis.

As shown in fig. 2, the bridge pattern 114 includes a plurality of

bridge lines

230a and 230 b. The

bridge lines

230a and 230b are located at different layers on the substrate SB with the first electrode block 112, the second electrode block 122, and the connection pattern 124. Therefore, the

bridge wires

230a and 230b are respectively electrically connected to two adjacent first electrode blocks 112 through two through holes (Via Hole)240, and the

bridge wires

230a and 230b cross the connection patterns 124. In some embodiments, the

bridge lines

230a and 230b are each disposed between two corresponding rows of the pixel circuits PX, and do not overlap with projections of the pixel circuits PX in the Z-axis direction. In other embodiments, the

bridge lines

230a and 230b are not disposed between two same rows of pixel circuits PX, and are spaced apart from each other by at least one row of pixel circuits PX. It is noted that the number of the bridge lines in fig. 2 is only an exemplary embodiment, and the bridge pattern 114 may include one or more bridge lines according to actual design requirements.

In addition, the connection pattern 124 is used for coupling two adjacent second electrode blocks 122, and the edge thereof may have no protrusion, so that the connection pattern 124 is substantially rectangular. The connection pattern 124 overlaps projections of the plurality of pixel circuits PX in the direction of the Z-axis.

FIG. 3A is a simplified cross-sectional view of an embodiment taken along line A-A' of FIG. 2. In this embodiment, the pixel circuit PX is a liquid crystal pixel circuit, and the electronic device 100 sequentially includes, from bottom to top, a lower glass substrate 310, a transparent conductive film layer (including the first electrode block 112, the second electrode block 122, and the connection pattern 124), an insulating layer 320, a thin-film transistor layer 330 (including the bridge pattern 114), a liquid crystal layer 340, and an upper glass substrate 350. The via 240 penetrates the insulating layer 320 so that the bridge pattern 114 can be electrically connected to the first electrode block 112. The first touch electrodes 110_1 to 110_5 and the second touch electrodes 120_1 to 120_4 together form a common electrode layer of the pixel circuit PX, and are used for providing one or more common voltages for the pixel circuit PX, wherein the one or more common voltages can be used for performing a polarity inversion operation and can be associated with a gray level provided by the pixel circuit PX.

The pixel circuit PX may include one or more switching transistors and a luminance determining circuit for determining a gray level provided by the pixel circuit PX and coupled to a corresponding one of the first touch electrodes 110_1 to 110_5 or a corresponding one of the second touch electrodes 120_1 to 120_ 4. For example, in some embodiments, pixel circuit PX may be implemented with pixel circuit 300 of fig. 3B. The pixel circuit 300 includes one or more switching transistors Ms and a luminance determining circuit 360, wherein the luminance determining circuit 360 includes a storage capacitor Cs and a liquid crystal capacitor Clc. The switching transistor Ms is selectively turned on or off according to the control signal Sc to write the data voltage Vdata into the storage capacitor Cs and the liquid crystal capacitor Clc. A first terminal of the storage capacitor Cs is coupled to the liquid crystal capacitor Clc and the switch transistor Ms, and a second terminal of the storage capacitor Cs is coupled to a corresponding one of the first touch electrodes 110_ 1-110 _5 or a corresponding one of the second touch electrodes 120_ 1-120 _ 4. For simplicity, in fig. 3B, one of the first touch electrodes 110_1 to 110_5 and one of the second touch electrodes 120_1 to 120_4 are respectively denoted by

reference numerals

110 and 120.

In the embodiment of fig. 2, when the electronic device 100 is viewed from the Z-axis direction, the bridging pattern 114 is located above the first electrode block 112, the second electrode block 122 and the connecting pattern 124, but the disclosure is not limited thereto.

In some embodiments, the bridging pattern 114 is located under the first electrode block 112, the second electrode block 122 and the connecting pattern 124 when the electronic device 100 is viewed from the Z-axis direction. In this case, a cross-sectional view taken along the line A-A' in FIG. 2 is as shown in FIG. 4A. In the embodiment of fig. 4A, the pixel circuit PX is an organic light emitting diode pixel circuit, and the electronic device 100 sequentially includes, from bottom to top, a lower substrate 410, a thin film transistor layer 420 (including the bridge pattern 114), an insulating layer 430, a transparent conductive film layer (including the first electrode block 112, the second electrode block 122 and the connection pattern 124), and an upper substrate 440. The via hole 240 passes through the insulating layer 430 so that the bridge pattern 114 can be electrically connected to the first electrode block 112. The first touch electrodes 110_1 to 110_5 and the second touch electrodes 120_1 to 120_4 are coupled to cathodes or anodes of organic light emitting diodes (not shown in fig. 4A) of the pixel circuits PX, and are configured to provide one or more operating voltages to the pixel circuits PX, wherein the one or more operating voltages may be associated with gray levels provided by the pixel circuits PX.

For example, in some embodiments, pixel circuit PX may be implemented with pixel circuit 400 of fig. 4B. The pixel circuit 400 includes one or more switching transistors Ms and a luminance determining circuit 450, wherein the luminance determining circuit 450 includes a driving transistor Md, a storage capacitor Cs and an organic light emitting diode Ld. The driving transistor Md has a first terminal for receiving the operating voltage VDD, a second terminal coupled to the anode terminal of the organic light emitting diode Ld, and a control terminal coupled to the switching transistor Ms and the storage capacitor Cs. The switching transistor Ms is selectively turned on or off according to the control signal Sc to write the data voltage Vdata into the storage capacitor Cs. The cathode terminal of the organic light emitting diode Ld is coupled to a corresponding one of the first touch electrodes 110_1 to 110_5 or a corresponding one of the second touch electrodes 120_1 to 120_4 to receive the working voltage VSS. For simplicity, in fig. 4B, one of the first touch electrodes 110_1 to 110_5 and one of the second touch electrodes 120_1 to 120_4 are respectively denoted by

reference numerals

110 and 120.

In other embodiments, the pixel circuit 400 may also be modified to have an anode terminal of the organic light emitting diode Ld coupled to a corresponding one of the first touch electrodes 110_1 to 110_5 or a corresponding one of the second touch electrodes 120_1 to 120_4 to receive the operating voltage VDD. In this case, the cathode terminal of the organic light emitting diode Ld is coupled to the first terminal of the driving transistor Md, and the second terminal of the driving transistor Md is for receiving the operating voltage VSS.

Please refer to fig. 1 and fig. 5 simultaneously. Fig. 5 is an enlarged view of the region 160 in fig. 1. As can be seen from fig. 5, the signal transmission pattern 150 includes a plurality of

signal transmission lines

510a and 510 b. The

signal transmission lines

510a and 510b and the second electrode block 122 (and the first electrode block 112 and the connection pattern 124) are disposed at different layers, and thus are coupled to the second electrode block 122 through the through holes 520, respectively. In some embodiments, the

signal transmission lines

510a and 510b are each disposed between two corresponding rows of pixel circuits PX, and do not overlap with projections of the pixel circuits PX in the Z-axis direction. In other embodiments, the

signal transmission lines

510a and 510b may not be disposed between two identical rows of pixel circuits PX, and may be spaced apart from each other by at least one row of pixel circuits PX. It is noted that the number of signal transmission lines in fig. 5 is only an exemplary embodiment, and the signal transmission pattern 150 may include one or more signal transmission lines according to actual design requirements.

The aforementioned coupling manner between the second electrode block 122 and the signal transmission pattern 150 is also applicable to the coupling manner between the first electrode block 112 and the signal transmission pattern 150, and for the sake of brevity, repeated descriptions are omitted here.

Fig. 6 is a waveform diagram of the electronic device 100 receiving a touch input. For convenience of illustration, only a portion of the touch electrodes are shown in fig. 6. In the present embodiment, the touch input is generated by a stylus 610 approaching the electronic device 100. The stylus 610 moves on the second touch electrode 120_1 and moves from a position close to the first touch electrode 110_1 to another position close to the first touch electrode 110_ 2.

In the case that the stylus pen 610 is closer to the first touch electrode 110_1, when the control circuit 130 sequentially transmits the scan signals Tx1 and Tx2 to the first touch electrodes 110_1 and 110_2, the control circuit 130 sequentially receives the pulse wave with higher intensity and the pulse wave with lower intensity of the sensing signal Rx 1. On the other hand, when the stylus 610 is closer to the first touch electrode 110_2, the control circuit 130 sequentially receives the pulse wave with the lower intensity and the pulse wave with the higher intensity of the sensing signal Rx1 when the control circuit 130 sequentially transmits the scan signals Tx1 and Tx2 to the first touch electrodes 110_1 and 110_2 again. Therefore, the control circuit 130 can accurately determine the moving track of the stylus pen 610 according to the waveform of the sensing signal Rx 1.

As can be seen from the above, one of the advantages of the electronic device 100 is that it overcomes the problem that the conventional in-cell touch display having a plurality of rectangular touch electrodes arranged in a matrix is not suitable for a touch pen. Another advantage of the electronic device 100 is that the number of signal transmission patterns 150 from the touch electrodes to the control circuit 130 is greatly reduced, thereby facilitating the design of the touch chip and reducing the risk of short circuit between the touch electrodes to improve the reliability of the product.
