[0072] The following will illustrate the embodiments of the present disclosure with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar elements or method flows.

[0073] Figure 1 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 capacitive 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 arranged in sequence in the X axis direction. The second touch electrodes 120_1 to 120_4 are parallel to the X axis and are arranged in sequence 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 arranged alternately. 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.

[0074] The control circuit 130 is used to transmit a plurality of scan signals Tx1-Tx5 to the first touch electrodes 110_1-110_5, and to receive a plurality of sensing signals Rx1-Rx4 from the second touch electrodes 120_1-120_4, respectively. When a touch input (e.g., a user's finger or a stylus) approaches the electronic device 100, the mutual capacitance values ​​between the first touch electrodes 110_1-110_5 and the second touch electrodes 120_1-120_4 will change, and the magnitudes of the sensing signals Rx1-Rx4 will reflect the changes in the mutual capacitance values. Therefore, the control circuit 130 can calculate the position of the touch input on the X-axis and the Y-axis according to the sensing signals Rx1-Rx4.

[0075] In some embodiments, the electronic device 100 further includes a variety of components for realizing display functions, such as a scan driving circuit, a backlight module, and one or more of a plurality of pixel circuits. For the sake of simplicity, these components and their connection relationships are not shown in the figure. Figure 1When the electronic device 100 is viewed from above in the direction of the 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 used to provide a display screen to the user, and other areas of the substrate SB surrounding the active area AA are the peripheral area PA. The peripheral area PA may be used to set up a scan drive circuit to provide control signals required for the operation of the pixel circuit. The relevant technologies of the scan drive circuit are well known to those having ordinary knowledge in the relevant technical field, and for the sake of brevity, they will not be described in detail here.

[0076] In some embodiments, the electronic device 100 may be a smart phone, a tablet computer, or a notebook computer, or may be an embedded touch display panel disposed in the aforementioned devices.

[0077] It is worth noting that Figure 1 The number of the first touch electrodes 110_1 to 110_5 and the second touch electrodes 120_1 to 120_4 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 of different sizes or to meet different resolution requirements.

[0078] exist Figure 1 In the embodiment of the present invention, the control circuit 130 is disposed outside the substrate SB and can be connected to the substrate SB through chip on film (COF) technology, but the present disclosure is not limited thereto. In other embodiments, the control circuit 130 can also be directly disposed on the substrate SB using chip on glass (COG) technology.

[0079] Please refer to Figure 1 , each of the first touch electrodes 110_1~110_5 includes a plurality of first electrode blocks 112 and a plurality of bridge patterns 114. The plurality of first electrode blocks 112 and the plurality of bridge patterns 114 are connected in series, that is, two adjacent first electrode blocks 112 are coupled to each other through a bridge pattern 114. Each of the second touch electrodes 120_1~120_4 includes a plurality of second electrode blocks 122 and a plurality of connection patterns 124. The plurality of second electrode blocks 122 and the plurality of connection patterns 124 are connected in series, that is, two adjacent second electrode blocks 122 are coupled to each other through a connection pattern 124. Each bridge pattern 114 crosses a corresponding connection pattern 124 in the Z-axis direction, and the first electrode blocks 112, the second electrode blocks 122 and the connection patterns 124 are arranged on the same layer on the substrate SB, and the bridge pattern 114 is arranged on another different layer on the substrate SB. In the following Figure 2middle, Figure 1 The area 140 in FIG. 1 will be enlarged to illustrate the above-mentioned stacking relationship in detail.

[0080] Each first electrode block 112 and each second electrode block 122 are substantially rectangular or rhombus-shaped, but the present disclosure is not limited thereto. In some embodiments, the first electrode blocks 112 at both ends (e.g., the head end and the tail end) of each of the first touch electrodes 110_1 to 110_5 may be substantially triangular, and the second electrode blocks 122 at both ends (e.g., the head end and the tail end) of each of the second touch electrodes 120_1 to 120_4 may also be substantially triangular. In other embodiments, the plurality of first electrode blocks 112 and the plurality of second electrode blocks 122 are electrically isolated from each other. In yet other embodiments, the plurality of first electrode blocks 112 and the plurality of second electrode blocks 122 may be implemented with various suitable transparent conductive films, such as an indium tin oxide (ITO) film or an aluminum zinc oxide (AZO) film.

[0081] exist Figure 1 In the embodiment of the present invention, 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 its end, and receives one of the scanning 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 transmits 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 its own Figure 1 The second second electrode block 122 from the right is coupled to the signal transmission pattern 150. For another example, the second touch electrode 120_2 is connected to the signal transmission pattern 150 by itself. Figure 1 The third second electrode block 122 from the right is coupled to the signal transmission pattern 150, and the rest are similar. However, the connection method between 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 its head or tail. Figure 5 middle, Figure 1 The region 160 will be enlarged to further illustrate the manner in which the first touch electrodes 110_1 ˜ 110_5 and the second touch electrodes 120_1 ˜ 120_4 are electrically connected to the signal transmission pattern 150 .

[0082] Figure 2 for Figure 1140 is a schematic diagram of an enlarged area 140. In some embodiments, the plurality of pixel circuits PX are used to receive one or more voltages required for operation from the first touch electrodes 110_1 to 110_5 and the second touch electrodes 120_1 to 120_4. Therefore, at least one edge of the first electrode block 112 is serrated, and at least one edge of the second electrode block 122 is also serrated, so as to project corresponding to the plurality of pixel circuits PX. Figure 2 The symbols R, G and B in each pixel circuit PX block represent that the pixel circuit PX is used to emit red light, green light and blue light, respectively, but the color arrangement and combination of the pixel circuit PX in the present disclosure are not limited thereto.

[0083] Specifically, on the plane where the X-axis and the Y-axis are located, 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 the first protrusions 210 and the second protrusions 220 overlaps with the projection of the corresponding one or more pixel circuits PX in the Z-axis direction.

[0084] 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 circuit PX in the direction of the Z axis.

[0085] like Figure 2 As shown, the bridge pattern 114 includes a plurality of bridge lines 230a and 230b. The bridge lines 230a and 230b are located on different layers on the substrate SB from the first electrode block 112, the second electrode block 122, and the connection pattern 124. Therefore, the bridge lines 230a and 230b are respectively electrically connected to two adjacent first electrode blocks 112 through two through holes (Via Hole) 240, and the bridge lines 230a and 230b cross the connection pattern 124. In some embodiments, the bridge lines 230a and 230b are respectively arranged between the corresponding two rows of pixel circuits PX, and do not overlap with the projection of the pixel circuits PX in the Z-axis direction. In other embodiments, the bridge lines 230a and 230b are not arranged between the same two rows of pixel circuits PX, and are separated from each other by at least one row of pixel circuits PX. It is worth noting that Figure 2 The number of bridge lines is only an exemplary embodiment, and the bridge pattern 114 may include one or more bridge lines according to actual design requirements.

[0086] In addition, the connection pattern 124 is used to couple two adjacent second electrode blocks 122, and its edge may not have a protrusion, so that the connection pattern 124 is substantially rectangular. The connection pattern 124 overlaps the projection of the plurality of pixel circuits PX in the direction of the Z axis.

[0087] Figure 3A For along Figure 2 The cross-sectional diagram of the simplified embodiment along the section line AA' is shown. In the present embodiment, the pixel circuit PX is a liquid crystal pixel circuit, and the electronic device 100 includes, from bottom to top, a lower glass substrate 310, a transparent conductive film layer (including a first electrode block 112, a second electrode block 122, and a connection pattern 124), an insulating layer 320, a thin film transistor layer 330 (including a bridge pattern 114), a liquid crystal layer 340, and an upper glass substrate 350. The through hole 240 passes through 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 to provide one or more common voltages for the pixel circuit PX, wherein the one or more common voltages can be used to perform a polarity inversion operation and can be associated with the grayscale provided by the pixel circuit PX.

[0088] The pixel circuit PX may include one or more switch transistors and a brightness determination circuit, wherein the brightness determination circuit is used to determine the grayscale provided by the pixel circuit PX and 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. Figure 3B The pixel circuit 300 is implemented. The pixel circuit 300 includes one or more switch transistors Ms and a brightness determination circuit 360, wherein the brightness determination circuit 360 includes a storage capacitor Cs and a liquid crystal capacitor Clc. The switch transistor Ms is used to selectively turn 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. The first end of the storage capacitor Cs is coupled to the liquid crystal capacitor Clc and the switch transistor Ms, and the second end of the storage capacitor Cs 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. For the sake of simplicity, Figure 3B In the drawings, reference numerals 110 and 120 respectively represent one of the first touch electrodes 110_1 to 110_5 and one of the second touch electrodes 120_1 to 120_4 .

[0089] In the aforementioned Figure 2 In the embodiment, when the electronic device 100 is viewed from the Z-axis direction, the bridge pattern 114 is located above the first electrode block 112, the second electrode block 122 and the connection pattern 124, but the present disclosure is not limited thereto.

[0090] In some embodiments, when the electronic device 100 is viewed from the Z-axis direction, the bridge pattern 114 is located below the first electrode block 112, the second electrode block 122, and the connection pattern 124. Figure 2The cross-section obtained along the middle section line A-A' is as follows Figure 4A As shown. Figure 4A In the embodiment of FIG. 1 , the pixel circuit PX is an organic light emitting diode pixel circuit, and the electronic device 100 includes, from bottom to top, a lower substrate 410, a thin film transistor layer 420 (including a bridge pattern 114), an insulating layer 430, a transparent conductive film layer (including a first electrode block 112, a second electrode block 122 and a connecting pattern 124), and an upper substrate 440. The through 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 the organic light emitting diodes (not shown) of the plurality of pixel circuits PX. Figure 4A ) is a cathode or an anode of the pixel circuit PX and is used to provide one or more operating voltages to the pixel circuit PX, wherein the one or more operating voltages can be associated with the gray scale provided by the pixel circuit PX.

[0091] For example, in some embodiments, the pixel circuit PX may be Figure 4B The pixel circuit 400 is implemented. The pixel circuit 400 includes one or more switching transistors Ms and a brightness determination circuit 450, wherein the brightness determination circuit 450 includes a driving transistor Md, a storage capacitor Cs and an organic light emitting diode Ld. The first end of the driving transistor Md is used to receive the operating voltage VDD, the second end thereof is coupled to the anode end of the organic light emitting diode Ld, and the control end thereof is coupled to the switching transistor Ms and the storage capacitor Cs. The switching transistor Ms is used to selectively turn on or off according to the control signal Sc to write the data voltage Vdata into the storage capacitor Cs. The cathode end 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 operating voltage VSS. For the sake of simplicity, Figure 4B In the drawings, reference numerals 110 and 120 respectively represent one of the first touch electrodes 110_1 to 110_5 and one of the second touch electrodes 120_1 to 120_4 .

[0092] In other embodiments, the pixel circuit 400 may also be changed to couple the anode terminal of the organic light emitting diode Ld 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 used to receive the operating voltage VSS.

[0093] Please also refer to Figure 1 and Figure 5 . Figure 5 for Figure 1 A schematic diagram of an enlarged area 160 in the middle. Figure 5 It can be seen that the signal transmission pattern 150 includes a plurality of signal transmission lines 510a and 510b. The signal transmission lines 510a and 510b are arranged in different layers from the second electrode block 122 (as well as the first electrode block 112 and the connection pattern 124), and thus are each coupled to the second electrode block 122 through the through hole 520. In some embodiments, the signal transmission lines 510a and 510b are each arranged between the corresponding two rows of pixel circuits PX, and do not overlap with the projection of the pixel circuit PX in the Z-axis direction. In other embodiments, the signal transmission lines 510a and 510b are not arranged between the same two rows of pixel circuits PX, and are separated from each other by at least one row of pixel circuits PX. It is worth noting that Figure 5 The number of signal transmission lines is merely an exemplary embodiment, and the signal transmission pattern 150 may include one or more signal transmission lines according to actual design requirements.

[0094] The aforementioned coupling method between the second electrode block 122 and the signal transmission pattern 150 is also applicable to the coupling method between the first electrode block 112 and the signal transmission pattern 150 , and for the sake of brevity, it will not be repeated here.

[0095] Figure 6 1 is a waveform diagram of the electronic device 100 receiving a touch input. Figure 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.

[0096] When 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 pulses of the sensing signal Rx1 with a higher intensity and the pulses of the sensing signal Rx1 with a lower intensity. On the other hand, when the stylus pen 610 is closer to the first touch electrode 110_2, when the control circuit 130 sequentially transmits the scan signals Tx1 and Tx2 to the first touch electrodes 110_1 and 110_2 again, the control circuit 130 sequentially receives the pulses of the sensing signal Rx1 with a lower intensity and the pulses of the sensing signal Rx1 with a higher intensity. Therefore, the control circuit 130 can accurately determine the moving trajectory of the stylus pen 610 according to the waveform of the sensing signal Rx1.

[0097] 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 embedded touch display with a plurality of rectangular touch electrodes arranged in a matrix is ​​not suitable for a stylus. 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 helping to simplify the design of the touch chip and helping to reduce the risk of short circuits between the touch electrodes and improve product reliability.

[0098] Certain words are used in the specification and claims to refer to specific components. However, those with ordinary knowledge in the technical field should understand that the same component may be referred to by different nouns. The specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as a basis for distinction. The term "including" mentioned in the specification and claims is an open-ended term, so it should be interpreted as "including but not limited to". In addition, "coupling" here includes any direct and indirect connection means. Therefore, if the text describes a first component coupled to a second component, it means that the first component can be directly connected to the second component through electrical connection or signal connection methods such as wireless transmission, optical transmission, etc., or indirectly electrically or signal connected to the second component through other components or connection means.

[0099] The dimensions and relative sizes of some components in the drawings may be exaggerated, or the shapes of some components may be simplified, so as to more clearly express the content of the embodiments. Therefore, unless otherwise specified by the applicant, the shapes, dimensions, relative sizes and relative positions of the components in the drawings are only for the convenience of explanation and should not be used to limit the scope of the claims of the present disclosure. In addition, the present disclosure may be embodied in many different forms, and when interpreting the present disclosure, it should not be limited to the embodiments set forth in this specification.

[0100] In addition, unless otherwise specified in the specification, any singular term also includes the plural term.

[0101] The above are only preferred embodiments of the present disclosure. All equivalent changes and modifications made according to the claims of the present disclosure should fall within the scope of the present disclosure.
