[0031] With the development of display panel technology, the display resolution of panels continues to improve, thus increasing the number of circuits related to display and touch sensing signal processing. To reduce the area occupied by these circuits, some simplified circuitry solutions have been developed. However, the application of simplified circuits can easily affect the continuity of the sensing signal, causing discontinuities in the value or changes of the sensing signal.

[0032] In the following embodiments, the present invention proposes a novel panel device circuit design, including the configuration of vias and the design of panel traces. Compared with existing technologies, the panel device circuit design proposed in this invention can effectively improve the continuity of sensing signals, thereby improving the quality of sensing signals.

[0033] Figure 1This diagram illustrates a panel device according to an embodiment of the present invention. The panel device 100 may be a panel device disposed on an electronic device or a portable electronic device. The panel device 100 may include a display panel 110 and a circuit board 120, wherein the circuit board 120 may be a flexible printed circuit board. The display panel 110 may include a display area 150 and a non-display area, wherein the display area 150, also known as the active area, is the range of the screen of the panel device that effectively displays the image, while the area on the display panel 110 other than the display area 150 is the non-display area. The non-display area is the area on the display panel 110 where no image is displayed, and it may include the border area of ​​the display panel 110. A fan-out area 160 is located in the non-display area of ​​the display panel 110, and signal transmission between the display panel 110 and the circuit board 120 can be accomplished through the wiring layout of the fan-out area 160.

[0034] According to one embodiment of the present invention, the display panel 110 may be a touch panel, and the control circuit 121 may be a circuit for controlling the display and touch sensing operations of the display panel 110, and may further control the display of the display panel 110 based on the result of touch sensing. According to different embodiments of the present invention, the control circuit 121 may be disposed on the circuit board 120, or may be disposed within the area of ​​the display panel 110 instead of on the circuit board 120. The present invention is not limited to any one embodiment.

[0035] In one embodiment of the present invention, the control circuit 121 may be an integrated chip, such as a Touch with Display Driver Integration (TDDI) chip. It should be noted that in some embodiments of the present invention, more than one control circuit or more than one chip may be provided on the circuit board 120 or within the display panel 110. For example, the panel device 100 may include multiple light sensors, and an Ambient Light Sensor (ALS) driver chip may be provided on the circuit board 120 to control ambient light sensing operation and further control the display of the display panel 110 based on the result of ambient light sensing.

[0036] According to one embodiment of the present invention, the panel device 100 may include a sensor array. The sensor array may include a plurality of sensing electrodes 155 arranged in a plurality of columns and a plurality of rows. According to one embodiment of the present invention, the sensing electrodes 155 may be capacitive touch sensing elements, or touch sensing electrodes. Each sensing electrode 155 corresponds to a sensing area of ​​the display panel and is used to sense the coupling capacitance generated in the corresponding area. The control circuit 121 may receive a plurality of sensing signals generated by the sensing electrodes 155, which may reflect the coupling capacitance sensed by the corresponding sensing electrode 155. By monitoring the capacitance change, the control circuit 121 may determine whether the display panel has been touched.

[0037] The control circuit 121 may include multiple receiving circuits, which receive the aforementioned sensing signals through corresponding receiving pins. According to one embodiment of the present invention, to reduce the number of traces in the bezel area and the number of receiving circuits and receiving pins, each receiving circuit may be shared by multiple sensing electrodes 155, and the fan-out area 160 of the panel device 100 may be configured with one or more multiplexers (Touch Pad (TP) multiplexer, abbreviated as TPMUX) for switching the electrical connection between the receiving circuit and different sensing electrodes. According to one embodiment of the present invention, the multiplexer may be an N-to-1 multiplexer, including N input terminals and 1 output terminal, to implement a circuit architecture in which N sensing electrodes share 1 receiving pin and 1 receiving circuit, where N is a positive integer and N is typically greater than 1. The input terminals of the multiplexer may be coupled to different traces, and the output terminals may be coupled to corresponding receiving pins and receiving circuits, so that the receiving circuit can sequentially receive sensing signals generated by different sensing electrodes.

[0038] Since the panel device 100 has display and touch capabilities, its operating timing can include a display time interval for performing display driving and a touch sensing time interval for performing touch sensing operations. According to an embodiment of the present invention, the touch sensing time interval of the panel device 100 can be divided into multiple sensing cycles; for example, a touch sensing time interval can include N sensing cycles. Through the switching operation of a multiplexer, the receiving circuit can be coupled to different sensing electrodes in different sensing cycles to receive corresponding sensing signals.

[0039] According to one embodiment of the present invention, to improve the continuity of the sensing signal, sensing electrodes coupled to the receiving circuit to perform touch sensing operations during the same sensing cycle can be arranged at adjacent positions in the display area 150. According to another embodiment of the present invention, the display area 150 of the display panel 110 can be divided into multiple areas, and sensing electrodes arranged in the same area can be coupled to the corresponding receiving circuit during the same sensing cycle to perform touch sensing operations on the corresponding sensing area at the same time.

[0040] Because the amount of noise on the panel can vary significantly at different times, if adjacent sensing electrodes are coupled to the corresponding receiving circuits during different sensing cycles, the resulting sensing signal values ​​or changes in values ​​will exhibit discontinuous characteristics, resulting in noise interspersed across the panel. Therefore, in embodiments of the present invention, by modifying the circuit design of the panel device, sensing electrodes disposed in the same area or adjacent to each other can be coupled to the corresponding receiving circuits during the same sensing cycle, enabling touch sensing operations to be performed on the corresponding sensing areas at the same time. In this way, the continuity of the sensing signal can be effectively improved.

[0041] The panel device circuit design proposed in this invention can be divided into two aspects in the following embodiments. The first aspect of this invention includes several embodiments that utilize via configuration to improve the continuity of sensing signals, and the second aspect of this invention includes several embodiments that utilize fan-out area routing design to improve the continuity of sensing signals.

[0042] Figure 2 This diagram shows a panel device according to an embodiment of a first aspect of the present invention. The panel device 200 may have the same elements as the panel device 100; that is, the panel device 200 may include, for example... Figure 1 The display panel, circuit board, display area, fan-out area, and control circuit shown are shown.

[0043] The panel device 200 may include a plurality of sensing electrodes arranged in a plurality of columns and rows to form a sensor array. For the sake of simplicity, Figure 2 Only one column of the sensor array is shown. Those skilled in the art will understand that the sensor array contains more than one column of sensing electrodes. Furthermore, although the following embodiment describes the circuit design and touch sensing operation of one column of sensing electrodes, those skilled in the art can deduce the relevant circuits and touch sensing operations of other columns of sensing electrodes, including channel configuration and the sequence of sensing signal transmission, based on the following related descriptions.

[0044] According to an embodiment of the present invention, the sensing electrodes include at least a first group of sensing electrodes disposed in a first region and a second group of sensing electrodes disposed in a second region. The first group of sensing electrodes and the second group of sensing electrodes may each comprise a plurality of sensing electrodes arranged in adjacent rows of a sensor array. For example, the first group of sensing electrodes may include sensing electrodes TP_21 and TP_22 disposed in region RG_21, and the second group of sensing electrodes may include sensing electrodes TP_23 and TP_24 disposed in region RG_22, wherein sensing electrodes TP_21, TP_22, TP_23, and TP_24 are located in the same column (e.g., the first column) of the sensing array and are sequentially disposed along a first direction. According to an embodiment of the present invention, the first direction may be a column direction or a vertical direction on a drawing. For example, sensing electrode TP_21 may be located in the first row of the first column of the sensor array, sensing electrode TP_22 may be located in the second row of the first column of the sensor array, sensing electrode TP_23 may be located in the third row of the first column of the sensor array, and sensing electrode TP_24 may be located in the fourth row of the first column of the sensor array.

[0045] The panel device 200 may also include multiple receiving circuits within the control circuitry, such as receiving circuits RX_21 and RX_22, and multiple traces extending along a first direction for transmitting the sensing signal generated at the sensing electrode, such as traces TS_21, TS_22, TS_23, and TS_24. According to an embodiment of the present invention, traces TS_21, TS_22, TS_23, and TS_24 may be sequentially arranged along a second direction, which may be a row direction or a horizontal direction on the drawing, and the second direction may be perpendicular to the first direction.

[0046] The panel device 200 may also include multiplexers MUX_21 and MUX_22. In this embodiment, multiplexers MUX_21 and MUX_22 may be 2-to-1 multiplexers, i.e., N=2, and a touch sensing time interval may include 2 sensing cycles. Multiplexer MUX_21 may selectively couple traces TS_21 and TS_22 to receiver circuit RX_21 at different sensing cycles in response to a control signal issued by the control circuit. Similarly, multiplexer MUX_22 may selectively couple traces TS_23 and TS_24 to receiver circuit RX_22 at different sensing cycles in response to a control signal issued by the control circuit.

[0047] In this embodiment, by switching the multiplexer MUX_21, the receiving circuit RX_21 can receive a first sensing signal generated by the sensing electrode TP_21 (i.e., generated in region RG_21) in a first sensing cycle and a third sensing signal generated by the sensing electrode TP_23 (i.e., generated in region RG_22) in a second sensing cycle. Similarly, by switching the multiplexer MUX_22, the receiving circuit RX_22 can receive a second sensing signal generated by the sensing electrode TP_22 (i.e., generated in region RG_21) in a first sensing cycle and a fourth sensing signal generated by the sensing electrode TP_24 (i.e., generated in region RG_22) in a second sensing cycle.

[0048] According to an embodiment of the present invention, in order to improve the continuity of the sensing signal received by the control circuit, in the same group of sensing electrodes, the channels corresponding to adjacent sensing electrodes or sensing electrodes arranged on adjacent rows can be arranged on non-adjacent traces, wherein the channel corresponding to a sensing electrode is used to couple or electrically connect the sensing electrode to a trace, and the channel can be a hole, a via, or a metal channel.

[0049] According to one embodiment of the present invention, when a touch sensing time interval of the panel device includes N sensing cycles, the channels corresponding to two adjacent sensing electrodes belonging to the same group of sensing electrodes are arranged with a spacing of (N-1) traces. For example, the channel corresponding to sensing electrode TP_21 and the channel corresponding to sensing electrode TP_22 are arranged with a spacing of 1 trace. Similarly, the channel corresponding to sensing electrode TP_23 and the channel corresponding to sensing electrode TP_24 are arranged with a spacing of 1 trace.

[0050] More specifically, the channels V_211, V_212 and V_213 corresponding to the sensing electrode TP_21 are configured on the trace TS_21. The sensing electrode TP_21 can be coupled to the trace TS_21 through the corresponding channels V_211, V_212 and V_213, and the first sensing signal generated by the sensing electrode TP_21 can be transmitted to the receiving circuit RX_21 through the trace TS_21.

[0051] Similarly, the channels V_221, V_222 and V_223 corresponding to the sensing electrode TP_22 are configured on the trace TS_23. The sensing electrode TP_22 can be coupled to the trace TS_23 through the corresponding channels V_221, V_222 and V_223, and the second sensing signal generated by the sensing electrode TP_22 can be transmitted to the receiving circuit RX_22 through the trace TS_23.

[0052] Similarly, channels V_231, V_232, and V_233 corresponding to the sensing electrode TP_23 are configured on the trace TS_22. The sensing electrode TP_23 can be coupled to the trace TS_22 through the corresponding channels V_231, V_232, and V_233, and the third sensing signal generated by the sensing electrode TP_23 can be transmitted to the receiving circuit RX_21 through the trace TS_22. Channels V_241, V_242, and V_243 corresponding to the sensing electrode TP_24 are configured on the trace TS_24. The sensing electrode TP_24 can be coupled to the trace TS_24 through the corresponding channels V_241, V_242, and V_243, and the fourth sensing signal generated by the sensing electrode TP_24 can be transmitted to the receiving circuit RX_22 through the trace TS_24.

[0053] Therefore, in this embodiment, the multiplexer MUX_21 can selectively couple traces TS_21 and TS_22 to the receiving circuit RX_21 at different induction cycles in response to a control signal, and the multiplexer MUX_22 can selectively couple traces TS_23 and TS_24 to the receiving circuit RX_22 at different induction cycles in response to a control signal.

[0054] It should be noted that, Figure 2 The number of channels shown (and in subsequent illustrations) is merely an example and not a limitation. In embodiments of the invention, the number of channels configured corresponding to a sensing electrode (and a trace) may be more or less than three.

[0055] In embodiments of the present invention, sensing electrodes configured in the same area can be coupled to the corresponding receiving circuits during the same sensing cycle to perform touch sensing operations on the corresponding sensing areas at the same time, thereby effectively improving the continuity of the sensing signal.

[0056] Figure 3 This diagram shows a panel device according to another embodiment of the first aspect of the present invention. The panel device 300 may have the same elements as the panel device 100; that is, the panel device 300 may include, for example... Figure 1 The display panel, circuit board, display area, fan-out area, and control circuit shown are shown.

[0057] In this embodiment, the multiplexers MUX_31, MUX_32 and MUX_33 can be 2-to-1 multiplexers, that is, N=2, and a touch sensing time interval can contain 2 sensing cycles. Figure 3 and Figure 2The main difference lies in the number of components. Therefore, for descriptions of regions RG_31 and RG_32, sensing electrodes TP_31, TP_32, TP_33 and TP_34, traces TS_31, TS_32, TS_33 and TS_34, multiplexers MUX_31 and MUX_32, receiving circuits RX_31 and RX_32, and channels V_311, V_312, V_313, V_321, V_322, V_323, V_331, V_332, V_333, V_341, V_342 and V_343, please refer to... Figure 2 The relevant descriptions of the regions RG_21 and RG_22, sensing electrodes TP_21, TP_22, TP_23 and TP_24, traces TS_21, TS_22, TS_23 and TS_24, multiplexers MUX_21 and MUX_22, receiving circuits RX_21 and RX_22, and channels V_211, V_212, V_213, V_221, V_222, V_223, V_231, V_232, V_233, V_241, V_242, and V_243 shown are not repeated here.

[0058] In this embodiment, the panel device 300 may further include a sensing electrode TP_35 located in the first column of the sensor array and configured in region RG_31, a sensing electrode TP_36 located in the first column of the sensor array and configured in region RG_32, channels V_351, V_352 and V_353 corresponding to the sensing electrode TP_35, and channels V_361, V_362 and V_363 corresponding to the sensing electrode TP_36. Furthermore, the panel device 300 may also include traces TS_35 and TS_36, a receiving circuit RX_33, and a multiplexer MUX_33.

[0059] According to one embodiment of the present invention, the multiplexer MUX_33 selectively couples traces TS_35 and TS_36 to the receiving circuit RX_33 at different induction cycles in response to a control signal. By switching the multiplexer MUX_33, the receiving circuit RX_33 can receive a fifth induction signal generated by the induction electrode TP_35 (i.e., generated in region RG_31) in a first induction cycle and a sixth induction signal generated by the induction electrode TP_36 (i.e., generated in region RG_32) in a second induction cycle.

[0060] According to one embodiment of the present invention, traces TS_35 and TS_36 are configured to continue from traces TS_31 to TS_34 along a second direction. Sensing electrode TP_35 can be coupled to trace TS_35 through channels V_351, V_352, and V_353, and sensing electrode TP_36 can be coupled to trace TS_36 through channels V_361, V_362, and V_363.

[0061] In embodiments of the present invention, sensing electrodes configured in the same area can be coupled to the corresponding receiving circuits during the same sensing cycle to perform touch sensing operations on the corresponding sensing areas at the same time, thereby effectively improving the continuity of the sensing signal.

[0062] Figure 4 This diagram illustrates a panel device according to another embodiment of the first aspect of the present invention. The panel device 400 may include a plurality of sensing electrodes arranged in a plurality of columns and rows to form a sensor array, and may have the same elements as the panel device 100; that is, the panel device 400 may include, for example... Figure 1 The diagram shows the display panel, circuit board, display area, fan-out area, and control circuitry. For the sake of simplicity, the diagrams and explanations are as follows: Figure 4 This section shows only one column of the sensor array and describes the circuit design and touch-sensing operation of the sensing electrodes in that column. Those skilled in the art can deduce the relevant circuits and touch-sensing operations of the sensing electrodes in other columns based on the following descriptions, including the channel configuration and the sequence of sensing signal transmission.

[0063] According to one embodiment of the present invention, the sensing electrode includes at least a first group of sensing electrodes disposed in a first region, a second group of sensing electrodes disposed in a second region, and a third group of sensing electrodes disposed in a third region. According to one embodiment of the present invention, the first group of sensing electrodes, the second group of sensing electrodes, and the third group of sensing electrodes may each comprise a plurality of sensing electrodes arranged in adjacent rows of a sensor array. For example, in… Figure 4 In the example shown, the first group of sensing electrodes may include sensing electrodes TP_41 and TP_42 disposed in region RG_41, the second group of sensing electrodes may include sensing electrodes TP_43 and TP_44 disposed in region RG_42, and the third group of sensing electrodes may include sensing electrodes TP_45 and TP_46 disposed in region RG_43.

[0064] Sensing electrodes TP_41, TP_42, TP_43, TP_44, TP_45, and TP_46 are located in the same column (e.g., the first column) of the sensing array and are arranged sequentially along a first direction, which can be a column direction or a vertical direction on the drawing. For example, sensing electrode TP_41 may be located in the first row of the first column of the sensor array, sensing electrode TP_42 may be located in the second row of the first column of the sensor array, sensing electrode TP_43 may be located in the third row of the first column of the sensor array, sensing electrode TP_44 may be located in the fourth row of the first column of the sensor array, sensing electrode TP_45 may be located in the fifth row of the first column of the sensor array, and sensing electrode TP_46 may be located in the sixth row of the first column of the sensor array.

[0065] The panel device 400 may also include multiple receiving circuits within the control circuitry, such as receiving circuits RX_41 and RX_42, and multiple traces extending along a first direction for transmitting the sensing signal generated at the sensing electrode, such as traces TS_41, TS_42, TS_43, TS_44, TS_45, and TS_46. According to an embodiment of the present invention, traces TS_41, TS_42, TS_43, TS_44, TS_45, and TS_46 may be sequentially arranged along a second direction, which may be a row direction or a horizontal direction on the drawing, and the second direction may be perpendicular to the first direction.

[0066] The panel device 400 may also include multiplexers MUX_41 and MUX_42. In this embodiment, multiplexers MUX_41 and MUX_42 may be 3-to-1 multiplexers, i.e., N=3, and a touch sensing time interval may include 3 sensing cycles. Multiplexer MUX_41 may selectively couple traces TS_41, TS_42, and TS_43 to receiver circuit RX_41 at different sensing cycles in response to a control signal issued by the control circuit. Similarly, multiplexer MUX_42 may selectively couple traces TS_44, TS_45, and TS_46 to receiver circuit RX_42 at different sensing cycles in response to a control signal issued by the control circuit.

[0067] In this embodiment, by switching the multiplexer MUX_41, the receiving circuit RX_41 can receive a first sensing signal generated by the sensing electrode TP_41 (i.e., generated in region RG_41) in a first sensing cycle, a third sensing signal generated by the sensing electrode TP_43 (i.e., generated in region RG_42) in a second sensing cycle, and a fifth sensing signal generated by the sensing electrode TP_45 (i.e., generated in region RG_43) in a third sensing cycle.

[0068] According to one embodiment of the present invention, in order to improve the continuity of the sensing signal received by the control circuit, in the same group of sensing electrodes, the channels corresponding to adjacent sensing electrodes or sensing electrodes arranged on adjacent rows can be arranged on non-adjacent traces.

[0069] As described above, when the multiplexer is an N-to-1 multiplexer, a touch sensing time interval of the panel device can include N sensing cycles, and the channels corresponding to two adjacent sensing electrodes belonging to the same group of sensing electrodes are arranged with a spacing of (N-1) lines. In this example, the channel corresponding to sensing electrode TP_41 and the channel corresponding to sensing electrode TP_42 are arranged with a spacing of 2 lines. Similarly, the channel corresponding to sensing electrode TP_43 and the channel corresponding to sensing electrode TP_44 are arranged with a spacing of 2 lines, and the channel corresponding to sensing electrode TP_45 and the channel corresponding to sensing electrode TP_46 are arranged with a spacing of 2 lines.

[0070] More specifically, the channels V_411, V_412 and V_413 corresponding to the sensing electrode TP_41 are configured on the trace TS_41. The sensing electrode TP_41 can be coupled to the trace TS_41 through the corresponding channels V_411, V_412 and V_413, and the first sensing signal generated by the sensing electrode TP_41 can be transmitted to the receiving circuit RX_41 through the trace TS_41.

[0071] Similarly, the channels V_421, V_422 and V_423 corresponding to the sensing electrode TP_42 are configured on the trace TS_44. The sensing electrode TP_42 can be coupled to the trace TS_44 through the corresponding channels V_421, V_422 and V_423, and the second sensing signal generated by the sensing electrode TP_42 can be transmitted to the receiving circuit RX_42 through the trace TS_44.

[0072] Similarly, the channels V_431, V_432 and V_433 corresponding to the sensing electrode TP_43 are configured on the trace TS_42. The sensing electrode TP_43 can be coupled to the trace TS_42 through the corresponding channels V_431, V_432 and V_433, and the third sensing signal generated by the sensing electrode TP_43 can be transmitted to the receiving circuit RX_41 through the trace TS_42.

[0073] The channels V_441, V_442 and V_443 corresponding to the sensing electrode TP_44 are configured on the trace TS_45. The sensing electrode TP_44 can be coupled to the trace TS_45 through the corresponding channels V_441, V_442 and V_443, and the fourth sensing signal generated by the sensing electrode TP_44 can be transmitted to the receiving circuit RX_42 through the trace TS_45.

[0074] The channels V_451, V_452 and V_453 corresponding to the sensing electrode TP_45 are configured on the trace TS_43. The sensing electrode TP_45 can be coupled to the trace TS_43 through the corresponding channels V_451, V_452 and V_453, and the fifth sensing signal generated by the sensing electrode TP_45 can be transmitted to the receiving circuit RX_41 through the trace TS_43.

[0075] The channels V_461, V_462 and V_463 corresponding to the sensing electrode TP_46 are configured on the trace TS_46.

[0076] Therefore, in this embodiment, the multiplexer MUX_41 can selectively couple traces TS_41, TS_42 and TS_43 to the receiving circuit RX_41 at different induction periods in response to a control signal, and the multiplexer MUX_42 can selectively couple traces TS_44, TS_45 and TS_46 to the receiving circuit RX_42 at different induction periods in response to a control signal.

[0077] In embodiments of the present invention, sensing electrodes configured in the same area can be coupled to the corresponding receiving circuits during the same sensing cycle to perform touch sensing operations on the corresponding sensing areas at the same time, thereby effectively improving the continuity of the sensing signal.

[0078] Furthermore, the first aspect of the present invention does not require changes to the routing design of the fan-out area, nor does it require changes to the design of the multiplexer, and it does not affect the design and width of the border area.

[0082] The panel device 500 may also include multiplexers MUX_51 and MUX_52. In this embodiment, multiplexers MUX_51 and MUX_52 may be 2-to-1 multiplexers, i.e., N=2, and a touch sensing time interval may include 2 sensing cycles. In this embodiment, the fan-out area of ​​the panel device 500 may include a cross-line structure 570. The cross-line structure 570 may include a plurality of line segments extending along a second direction, for example... Figure 5 The lines 571 and 572 are drawn in bold and connect portions of the traces. For example, line 571 connects trace TS_52 to an input of multiplexer MUX_52, and line 572 connects trace TS_53 to an input of multiplexer MUX_51.

[0083] According to one embodiment of the present invention, the number of traces may be an integer multiple of the number of line segments included in the crossover structure. For example, the number of traces may be twice the number of line segments included in the crossover structure, or the number of line segments included in the crossover structure may be half the number of traces.

[0084] Multiplexer MUX_51 can selectively couple traces TS_51 and TS_53 to receiver circuit RX_51 at different induction cycles in response to a control signal issued by the control circuit. Similarly, multiplexer MUX_52 can selectively couple traces TS_52 and TS_54 to receiver circuit RX_52 at different induction cycles in response to a control signal issued by the control circuit.

[0085] In this embodiment, the channels V_511, V_512 and V_513 corresponding to the sensing electrode TP_51 are configured on the trace TS_51. The sensing electrode TP_51 can be coupled to the trace TS_51 through the corresponding channels V_511, V_512 and V_513, and the first sensing signal generated by the sensing electrode TP_51 can be transmitted to the receiving circuit RX_51 through the trace TS_51.

[0086] The channels V_521, V_522 and V_523 corresponding to the sensing electrode TP_52 are configured on the trace TS_52. The sensing electrode TP_52 can be coupled to the trace TS_52 through the corresponding channels V_521, V_522 and V_523. The second sensing signal generated by the sensing electrode TP_52 can be transmitted to the receiving circuit RX_52 through the trace TS_52 and the line segment 571 in the cross-line structure 570.

[0087] The channels V_531, V_532 and V_533 corresponding to the sensing electrode TP_53 are configured on the trace TS_53. The sensing electrode TP_53 can be coupled to the trace TS_53 through the corresponding channels V_531, V_532 and V_533.

[0090] In embodiments of the present invention, sensing electrodes configured in the same area can be coupled to the corresponding receiving circuits during the same sensing cycle to perform touch sensing operations on the corresponding sensing areas at the same time, thereby effectively improving the continuity of the sensing signal.

[0091] Figure 6 This diagram shows a panel device according to another embodiment of the second aspect of the present invention. The panel device 600 may have the same elements as the panel device 100; that is, the panel device 600 may include, for example... Figure 1The display panel, circuit board, display area, fan-out area, and control circuit shown are shown.

[0092] Figure 6 and Figure 5 The main difference lies in the number of components. Figure 6 In the first group of sensing electrodes, sensing electrodes TP_61, TP_62 and TP_63 may be disposed in region RG_61, and sensing electrodes TP_64, TP_65 and TP_66 may be disposed in region RG_62, wherein sensing electrodes TP_61 to TP_66 are located in the same column (e.g., the first column) of the sensing array and are disposed sequentially along a first direction.

[0093] The panel device 600 may include a plurality of receiving circuits within a control circuit, such as receiving circuits RX_61, RX_62, and RX_63, and a plurality of traces extending along a first direction for transmitting the sensing signal generated at the sensing electrode, such as traces TS_61, TS_62, TS_63, TS_64, TS_65, and TS_66. According to an embodiment of the present invention, traces TS_61 to TS_66 may be sequentially arranged along a second direction, which may be a row direction or a horizontal direction on the drawing, and the second direction may be perpendicular to the first direction.

[0094] In this embodiment, the multiplexers MUX_61, MUX_62, and MUX_63 can be 2-to-1 multiplexers, i.e., N=2, and a touch sensing time interval can include 2 sensing cycles. Furthermore, in this embodiment, the fan-out area of ​​the panel device 600 may include a cross-line structure 670. The cross-line structure 670 may include a plurality of line segments extending along a second direction, for example... Figure 6 The lines 671, 672, and 673 are drawn in bold and connect portions of the traces. For example, line 671 connects trace TS_62 to an input of multiplexer MUX_62, line 672 connects trace TS_63 to an input of multiplexer MUX_63, and line 673 connects trace TS_65 to an input of multiplexer MUX_61.

[0095] According to one embodiment of the present invention, the number of traces may be an integer multiple of the number of line segments included in the crossover structure. For example, the number of traces may be twice the number of line segments included in the crossover structure, or the number of line segments included in the crossover structure may be half the number of traces.

[0096] Multiplexer MUX_61 can selectively couple traces TS_61 and TS_65 to receiver circuit RX_61 at different induction periods in response to a control signal issued by the control circuit. Multiplexer MUX_62 can selectively couple traces TS_62 and TS_64 to receiver circuit RX_62 at different induction periods in response to a control signal issued by the control circuit. Multiplexer MUX_63 can selectively couple traces TS_63 and TS_66 to receiver circuit RX_63 at different induction periods in response to a control signal issued by the control circuit.

[0097] In this embodiment, the channels V_611, V_612 and V_613 corresponding to the sensing electrode TP_61 are configured on the trace TS_61. The sensing electrode TP_61 can be coupled to the trace TS_61 through the corresponding channels V_611, V_612 and V_613, and the first sensing signal generated by the sensing electrode TP_61 can be transmitted to the receiving circuit RX_61 through the trace TS_61.

[0098] The channels V_621, V_622 and V_623 corresponding to the sensing electrode TP_62 are configured on the trace TS_62. The sensing electrode TP_62 can be coupled to the trace TS_62 through the corresponding channels V_621, V_622 and V_623. The second sensing signal generated by the sensing electrode TP_62 can be transmitted to the receiving circuit RX_62 through the trace TS_62 and the line segment 671 in the cross-line structure 670.

[0099] The channels V_631, V_632 and V_633 corresponding to the sensing electrode TP_63 are configured on the trace TS_63. The sensing electrode TP_63 can be coupled to the trace TS_63 through the corresponding channels V_631, V_632 and V_633. The third sensing signal generated by the sensing electrode TP_63 can be transmitted to the receiving circuit RX_63 through the trace TS_63 and the line segment 672 in the cross-line structure 670.

[0100] The channels V_641, V_642 and V_643 corresponding to the sensing electrode TP_64 are configured on the trace TS_64. The sensing electrode TP_64 can be coupled to the trace TS_64 through the corresponding channels V_641, V_642 and V_643, and the fourth sensing signal generated by the sensing electrode TP_64 can be transmitted to the receiving circuit RX_62 through the trace TS_64.

[0101] The channels V_651, V_652 and V_653 corresponding to the sensing electrode TP_65 are configured on the trace TS_65. The sensing electrode TP_65 can be coupled to the trace TS_65 through the corresponding channels V_651, V_652 and V_653. The fifth sensing signal generated by the sensing electrode TP_65 can be transmitted to the receiving circuit RX_61 through the trace TS_65 and the line segment 673 in the cross-line structure 670.

[0102] The channels V_661, V_662 and V_663 corresponding to the sensing electrode TP_66 are configured on the trace TS_66. The sensing electrode TP_66 can be coupled to the trace TS_66 through the corresponding channels V_661, V_662 and V_663, and the sixth sensing signal generated by the sensing electrode TP_66 can be transmitted to the receiving circuit RX_63 through the trace TS_66.

[0103] In this embodiment, by switching the multiplexer MUX_61, the receiving circuit RX_61 can receive a first sensing signal generated by the sensing electrode TP_61 (i.e., generated in region RG_61) in a first sensing cycle and a fifth sensing signal generated by the sensing electrode TP_65 (i.e., generated in region RG_62) in a second sensing cycle. By switching the multiplexer MUX_62, the receiving circuit RX_62 can receive a second sensing signal generated by the sensing electrode TP_62 (i.e., generated in region RG_61) in a first sensing cycle and a fourth sensing signal generated by the sensing electrode TP_64 (i.e., generated in region RG_62) in a second sensing cycle.

[0104] In embodiments of the present invention, sensing electrodes configured in the same area can be coupled to the corresponding receiving circuits during the same sensing cycle to perform touch sensing operations on the corresponding sensing areas at the same time, thereby effectively improving the continuity of the sensing signal.

[0105] In the embodiments of the present invention, although there may be significant differences in the fan-out resistance values ​​at the boundaries of different regions, the resulting change in resistance-capacitance load is not enough to affect the accuracy of touch sensing. Therefore, the circuit design of the panel device proposed in the present invention can still accurately sense the touch behavior of the panel.

[0106] Furthermore, the circuit design of the panel device proposed in this invention can be applied not only to panel devices with extended wiring (e.g., Figures 2 to 6 The example shown (where all traces extend from the fan-out area to the top of the display area) can also be applied to panel devices with non-extended traces.

[0107] Figure 7 This diagram illustrates a panel device according to an embodiment of the present invention. The panel device 700 may have the same elements as the panel device 100; that is, the panel device 700 may include, for example... Figure 1 The display panel, circuit board, display area, fan-out area, and control circuit shown are shown.

[0108] In this embodiment, the multiplexers MUX_71 and MUX_72 can be 2-to-1 multiplexers, that is, N=2, and a touch sensing time interval can contain 2 sensing cycles. Figure 7 and Figure 2 The main difference lies in whether the traces extend to the top of the display area. Therefore, for descriptions of the sensing electrodes TP_71, TP_72, TP_73 and TP_74, traces TS_71, TS_72, TS_73 and TS_74, multiplexers MUX_71 and MUX_72, receiving circuits RX_71 and RX_72, and areas and channels, please refer to... Figure 2 The relevant explanations will not be repeated here.

[0109] In this embodiment, each trace extends only from the receiving circuit to the corresponding sensing electrode and is coupled to the corresponding sensing electrode through a channel configured on the trace. In some embodiments, for layout consistency, redundant (dummy) traces may also be configured for the sensing electrodes, for example, in Figure 7 In the diagram, compared to the solid lines extending along the first direction, which are the actual traces capable of transmitting inductive signals, the dashed lines extending along the first direction are redundant traces. Corresponding channels can still be configured on the redundant traces, allowing the traces to be electrically connected to the corresponding inductive electrodes, but the redundant traces are not connected to the receiving circuit.

[0110] For panel devices with non-extended traces, the actual number of traces on each sensing electrode may vary, necessitating adjustments to the sensing signal value to compensate for the differences caused by the varying number of traces. However, this does not affect the application of this invention. In other words, the circuit design of the panel device proposed in this invention can also be applied to panel devices with non-extended traces.

[0111] In addition, it should be noted that, although Figure 7 This invention demonstrates the application of the concept of the first aspect of the invention to panel devices of the non-extended wiring type, but the invention is not limited thereto. The concept of the second aspect of the invention can also be applied to panel devices of the non-extended wiring type. Those skilled in the art can readily understand this from... Figure 7The contents shown and related descriptions lead to the design of panel wiring after applying the concept of the second aspect of the present invention to panel devices with non-extended wiring, so they will not be repeated here.

[0112] Figure 8 This diagram illustrates a panel device according to an embodiment of the present invention. The panel device 800 may include a plurality of sensing electrodes arranged in a plurality of columns and rows to form a sensor array, and may have the same elements as the panel device 100; that is, the panel device 800 may include, for example... Figure 1 The diagram shows the display panel, circuit board, display area, fan-out area, and control circuitry. For the sake of simplicity, the diagrams and explanations are as follows: Figure 8 This section shows only one column of the sensor array and describes the circuit design and touch-sensing operation of the sensing electrodes in that column. Those skilled in the art can deduce the relevant circuits and touch-sensing operations of the sensing electrodes in other columns based on the following descriptions, including the channel configuration and the sequence of sensing signal transmission.

[0113] Figure 8 This example demonstrates the application of M N-to-1 multiplexers in a panel device, where N and M are positive integers. The sensing electrodes may include N groups of sensing electrodes sequentially arranged in different regions along a first direction, each group of sensing electrodes being arranged in a corresponding region. For example, the sensing electrodes may include a first group of sensing electrodes concentrated in region RG_1, a second group of sensing electrodes concentrated in region RG_2, ..., and an Nth group of sensing electrodes concentrated in region RG_N. In this example, the sensing electrodes TP_1, TP_2, ..., TP_M, TP_(M+1), TP_(M+2), ..., TP_2*M, ..., TP_N*M are located in the same column (e.g., the first column) of the sensing array and are sequentially arranged along the first direction, which may be a column direction or a vertical direction on the drawing.

[0114] The panel device 800 may also include multiple receiving circuits in the control circuit, such as receiving circuits RX_1, RX_2, ..., RX_M, multiplexers MUX_1, MUX_2, ..., MUX_M, and multiple traces extending along the first direction for transmitting the sensing signal generated at the sensing electrode.

[0115] Multiplexer MUX_1 includes an output terminal coupled to receiver circuit RX_1 and N input terminals coupled to different traces. Multiplexer MUX_2 includes an output terminal coupled to receiver circuit RX_2 and N input terminals coupled to different traces. Multiplexer MUX_M includes an output terminal coupled to receiver circuit RX_M and N input terminals coupled to different traces, and so on.

[0116] In this embodiment, a touch sensing time interval may include N sensing cycles. Multiplexers MUX_1, MUX_2, ..., MUX_M can selectively couple different traces to the corresponding receiving circuits RX_1, RX_2, ..., RX_M in response to control signals issued by the control circuit.

[0117] According to one embodiment of the present invention, the channels corresponding to two adjacent sensing electrodes belonging to the same group of sensing electrodes are arranged with a spacing of (N-1) traces. As shown in the figure, in this example, the channel corresponding to sensing electrode TP_1 and the channel corresponding to sensing electrode TP_2 are arranged with a spacing of (N-1) traces. Similarly, the channel corresponding to sensing electrode TP_(M+1) and the channel corresponding to sensing electrode TP_(M+2) are arranged with a spacing of (N-1) traces, and the remaining channel arrangements are similar.

[0118] More specifically, channels V_11, V_12, and V_13 corresponding to sensing electrode TP_1 can be configured on the first trace, and channels V_21, V_22, and V_23 corresponding to sensing electrode TP_2 can be configured on the (N+1)th trace. Therefore, the channels corresponding to sensing electrode TP_1 and the channels corresponding to sensing electrode TP_2 are configured with an interval of (N-1) traces. Similarly, the channel corresponding to sensing electrode TP_(M+1) can be configured on the second trace, and channels V_21, V_22, and V_23 corresponding to sensing electrode TP_(M+2) can be configured on the (N+2)th trace. The channels corresponding to sensing electrode TP_(M+1) and the channels corresponding to sensing electrode TP_(M+2) are configured with an interval of (N-1) traces, and so on. The induced signals generated by the induction electrodes TP_1, TP_(M+1), ..., TP_((N-1)*M+1)) of different groups can be sequentially transmitted to the receiving circuit RX_1 through the corresponding traces and the switching of the multiplexer MUX_1 at different induction cycles. Similarly, the induced signals generated by the induction electrodes TP_2, TP_(M+2), ..., TP_((N-1)*M+2)) of different groups can be sequentially transmitted to the receiving circuit RX_2 through the corresponding traces and the switching of the multiplexer MUX_2 at different induction cycles, and the induced signals generated by the induction electrodes TP_M, TP_2*M, ..., TP_N*M of different groups can be sequentially transmitted to the receiving circuit RX_M through the corresponding traces and the switching of the multiplexer MUX_M at different induction cycles.

[0119] Therefore, the receiving circuits RX_1, RX_2, ..., RX_M can receive the induced signals generated by different groups of induction electrodes in different induction cycles through the N-to-1 multiplexers MUX_1, MUX_2, ..., MUX_M, respectively. Furthermore, by configuring channels with (N-1) spaced traces, the receiving circuits RX_1, RX_2, ..., RX_M can receive the induced signals generated by induction electrodes belonging to the same group in the same induction cycle through the N-to-1 multiplexers MUX_1, MUX_2, ..., MUX_M, respectively.

[0120] Continuing on the above, in the embodiments of the present invention, for a panel device using an N-to-1 multiplexer, by arranging the channel spacing (N-1) lines, the sensing electrodes arranged in the same area can be coupled to the corresponding receiving circuit in the same sensing cycle, so that the panel device can perform touch sensing operation in the corresponding sensing area at the same time using sensing electrodes that are close to or concentrated in the same position. In this way, the continuity of the sensing signal can be effectively improved.

[0121] In the first and second aspects of the present invention, the continuity of capacitance characteristics is improved by utilizing channel configuration and fan-out area routing design, thereby effectively improving the continuity of the sensed signal. Furthermore, the first aspect of the present invention offers additional design advantages because it does not require changes to the fan-out area routing design, the multiplexer design, or affect the design and width of the border area.
