Description

Technical Field

[0001] The present invention relates to a touch sensing device for a touch panel, and more particularly to a touch sensing device and a touch panel as a single or independent layer. Background Art

[0002] In the circuit layout structure of existing touch panels, each sensing element is connected to a flexible printed circuit board through a signal transmission line. When the number of sensing elements is large, the number of its signal transmission lines also increases accordingly. Correspondingly, the circuit layout is too complex and easily causes the yield rate of the touch panel to decrease.

[0003] Most general touch panels use a 4-PEP process. For products using ITO Bridge, there will be an additional yellow light process, becoming a 5-PEP process. As mentioned above, except that the vertically oriented lines will not be on the same process or the same layer as the horizontally oriented ones, it still requires a process after the OC1 PROCESS to be completed, so at least 4 - 5 processes are required.

[0004] In addition, the sensing element is used as a single or independent layer and covered on the display screen in a laminated display panel. When using this design method, a cover glass (CG) must be covered on the touch sensor, so the thickness of the display panel will be increased. Summary of the Invention

[0030] Please refer to Figure 1 , Figure 1 , a schematic diagram showing an embodiment of the touch sensing device of the touch panel of the present invention. The touch sensing device 100 includes a first conductive pattern 10, a second conductive pattern 20, and a virtual conductive pattern 30.

[0031] Note that, in this embodiment, the first conductive pattern 10 is a touch sensing electrode (Rx), the second conductive pattern 20 is a touch driving electrode (Tx), and the virtual conductive pattern 30 is an invalid electrode pattern (dummy pattern). For the sake of brevity, Figure 1 only one array unit in the touch sensing device 100 is illustrated, Figure 1 only three groups of the first conductive patterns 10, three groups of the second conductive patterns 20, and three groups of the virtual conductive patterns 30 are shown, but the present invention should not be limited thereto. The touch sensing device 100 may have multiple first conductive patterns 10, first conductive patterns 20, and virtual conductive patterns 30.

[0032] The first conductive pattern 10 is disposed on a first side S1 of the touch sensing device 100, and the top end T1 or the free end of the first conductive pattern 10 extends in a first direction D1. The first conductive patterns 10 are arranged in a second direction D2 different from the first direction D1; in this embodiment, the first conductive patterns 10 are arranged in the second direction D2 perpendicular to the first direction D1.

[0033] It should be noted that, except for the first conductive pattern 10 at the bottom of the touch sensing device 100, the top end T1 of each first conductive pattern 10 turns and extends in the second direction D2, and the first conductive patterns 10 are disposed on the first side S1 of the touch sensing device 100 and are connected to be parallel to the second direction D2. The extension termination of the top end T1a of the first conductive pattern 10 at the bottom of the touch sensing device 100 aligns with the connection axis of the top ends T1 of the first conductive patterns 10.

[0034] The second conductive pattern 20 is disposed on a second side S2 of the touch sensing device 100. The top end T2 or the free end of the second conductive pattern 20 extends in a direction different from the first direction D1 and then turns to extend in a direction different from the second direction D2. The second conductive patterns are arranged in the second direction D2 different from the first direction D1; in this embodiment, the top end T2 or the free end of the second conductive pattern 20 extends in the direction opposite to the first direction D1 and then turns to extend in the direction opposite to the second direction D2. The second conductive patterns are arranged in the second direction D2 different from the first direction D1, and the first side S1 is different from the second side S2, and the first side S1 is parallel to the second side S2.

[0035] Moreover, the top end T2 of the second conductive pattern 20 at the top of the touch sensing device 100 finally turns and extends toward the first direction D1, and each second conductive pattern 20 is disposed on the second side S2 of the connection device 100 and is connected to be parallel to the second direction D2; except for the second conductive pattern 20 at the top of the touch sensing device 100, the top ends T2 of the remaining second conductive patterns 20 are close to the first side S1, while the top end T2a of the second conductive pattern 20 at the top of the touch sensing device 100 is close to the second side S2.

[0036] Note that the top end T1 of the first conductive pattern 10 has a first preset distance from the second conductive pattern 20; the top end T2 of the second conductive pattern 20 has a second preset distance from the first conductive pattern 10.

[0037] A virtual conductive pattern 30 is disposed adjacent to the first conductive pattern 10 and the second conductive pattern 20, and the virtual conductive pattern 30 is arranged in the second direction D2. The virtual conductive pattern 30 has two forms in this embodiment. One is that the virtual conductive pattern 30 in the form of a strip 30a is disposed along the adjacent portion of the first conductive pattern 10 and the second conductive pattern 20, that is, the strip 30a is disposed at the first preset distance, the second preset distance, and the adjacent portion of the top end T1 of the first conductive pattern 10 and the second conductive pattern 20; the other is a plurality of polygonal regions 30b. The polygonal regions 30b extend from the adjacent portion of the top end T1 of the first conductive pattern 10 and the top end T2 of the second conductive pattern 20 in a direction opposite to the first direction D1 and terminate in a notch of the second conductive pattern 20 ( Figure 1 viewed from above). In one embodiment, the plurality of polygonal regions 30b are combined into N×M virtual conductive patterns 30. In one example, each polygonal region 30b is an octagonal block.

[0038] In one embodiment, the virtual conductive pattern 30 can be regarded as filling the blank area inside the first conductive pattern 10 and the second conductive pattern 20, that is, except for the areas where the first conductive pattern 10 and the second conductive pattern 20 are located, virtual conductive pattern 30 is provided. In other words, the virtual conductive pattern 30 fills the adjacent portion of the first conductive pattern 10 and the second conductive pattern 20.

[0039] As described above, the second conductive pattern 20 at the top of the touch sensing device 100 is in a U shape, and the remaining second conductive patterns 20 are in an L shape. The short side of the L shape is adjacent to the first side S1, the short side of the L shape is parallel to the second direction D2, and the long side is parallel to the second direction D1.

[0040] In another embodiment, when viewing the touch sensing device 100 from above, the first conductive pattern 10 encloses a plurality of long strip-shaped regions having polygons. Each long strip-shaped region has a notch G at the lower right edge, and the notch G provides an extension passage for the top end T2 or T2a of the second conductive pattern 20.

[0041] The first conductive pattern 10 is disposed on the first side S1 of the touch sensing device 100, and the left sides of each long strip-shaped region are connected to be parallel to the second direction D2; the second conductive pattern 20 is disposed on the second side S2 of the touch sensing device 100 and is connected and parallel to the second direction D2. The top end T2 of each second conductive pattern 20 is located in the long strip-shaped region of the corresponding first conductive pattern 10.

[0042] The first conductive pattern 10 is disposed on the first side S1 of the touch sensing device 100 and has a first common electrode E1. The first common electrode E1 is elongated and parallel to the second direction. The second conductive pattern 20 is disposed on the second side S2 of the touch sensing device 100 and has a second common electrode E2. The second common electrode E2 is elongated and parallel to the second direction D2. The tops T2 and T2a of each second conductive pattern are located within the corresponding elongated regions.

[0043] Figure 1 Each row of the first conductive patterns 10 of the display array can be regarded as a sensing electrode, and several driving electrodes Tx are placed adjacent to the sensing electrode Rx. Each row of the array includes a sensing electrode Rx, and several corresponding driving electrodes Tx are placed adjacent to the sensing electrode Rx. The traces coupling each driving electrode Rx to the touch controller are routed to pass through the channels between the rows and columns parallel to the array. Each row of sensing electrodes Rx is capacitively coupled to one or more adjacent driving electrodes Tx of that row, and a gap separates the driving electrodes Tx and the sensing electrodes Rx.

[0044] Please note that the touch sensing device 100 of this embodiment can be applied to a touch panel without a cover glass (CG), that is, the thickness of the window outer cover can be reduced in the touch panel stack structure.

[0045] Please refer to Figure 2 , in an embodiment, the first conductive pattern 10 protrudes from the first side S1 to form at least one L-shaped first electrode tooth a1 and at least one linear second electrode tooth a2; the second conductive pattern 20 protrudes from the second side S2 to form at least one U-shaped third electrode tooth a3 and at least one L-shaped fourth electrode tooth a4; wherein, N×M virtual conductive patterns 30 are disposed between the top T1 of the first electrode tooth a1 and the top T2a of the third electrode tooth a3, or between the top T1 of the first electrode tooth a1 and the top T2 of the fourth electrode tooth a4, and the virtual conductive patterns 30 extend in the first direction D1; and the third electrode tooth a3 or the fourth electrode tooth a4 is disposed between adjacent first electrode teeth a1, and the fourth electrode tooth a4 is disposed between the first electrode tooth a1 and the second electrode tooth a2.

[0046] In an embodiment, at least two sides of the N×M virtual conductive patterns 30 are surrounded by the first conductive pattern 10, and at least two sides of the N×M virtual conductive patterns 30 are surrounded by the second conductive pattern 20.

[0047] Please refer to Figure 2 , Figure 2Show the widths wrx1 to wrx3 of each part of the first conductive pattern 10, where the width wrx1 is 0.25 to 0.255 mm, the width wrx2 is 0.165 to 0.17 mm, and the width wrx3 is 0.184 to 0.185 mm; the widths wtx1 to wtx3 of the second conductive pattern 20, where the width wtx1 is 0.25 to 0.255 mm, the width wtx2 is 0.165 to 0.17 mm, and the width wtx3 is 0.245 to 0.25 mm; the width wdmy of the strip 30a of the virtual conductive pattern 30 is 0.12 to 0.13 mm. In one embodiment, the distance between adjacent first conductive patterns 10 is 2 to 3 mm.

[0048] This embodiment provides a single-layer touch sensing device 100. The driving electrode and the sensing electrode protrude from the main electrode line and thereby form an L-shaped electrode tooth. The electrode teeth of the driving electrode and the sensing electrode are arranged in a cross pattern, and N×M virtual electrodes are placed therein to keep a specific ratio between the driving electrode and the sensing electrode and the virtual electrode, so as to reduce the mutual capacitance between the driving electrode and the sensing electrode and improve its touch sensitivity.

[0049] In the embodiment, the electrode tooth of each sensing electrode is adjacent to one or more electrode teeth of the corresponding driving electrode, thereby forming capacitively coupled with a gap separation. The L-shaped electrode teeth are arranged in a finger-like cross pattern to increase the number of capacitively coupled between one or more driving electrodes and the corresponding sensing electrodes. The capacitive coupling between the sensing electrode and the corresponding driving electrode is determined by the gap and the edge size of the electrode tooth.

[0050] For example, the gap between the driving electrode and the sensing electrode and their corresponding L-shaped electrode teeth are divided into horizontal gaps and vertical gaps, and the gaps are evenly distributed. In another embodiment, the electrodes and their gaps at the edge of the sensor may be unevenly distributed.

[0051] Figure 2 N×M virtual electrodes are arranged in a ratio between the sensing electrode and its relative driving electrode's L-shaped electrode teeth. These virtual electrodes are located in the area outside the sensing electrode and the driving electrode and have a fixed interval from the sensing electrode and the driving electrode, which is proportional to the area of the sensing electrode and the driving electrode.

[0052] Please note that the width of the strip 30a is smaller than the widths of the first conductive pattern 10 and the second conductive pattern 20. Also, when viewed from above (i.e., Figure 1 the perspective), the first conductive pattern 10 and the second conductive pattern 20 are arranged horizontally and staggered in sequence along the second direction D2, and the area of the virtual conductive pattern 30 is 46 to 50% of the total area of the first conductive pattern 10 and the second conductive pattern 20.

[0053] In another embodiment, the sensing electrodes are divided into three types with widths ranging from 100 to 400 micrometers (μm), and the driving electrodes are also divided into three types with widths ranging from 100 to 400 micrometers (μm).

[0054] Please refer to Figure 3 , Figure 3 FIG. shows a schematic diagram of the touch panel of the present invention in an embodiment. The touch panel 200 uses the aforementioned touch sensing device 100, and the touch panel 200 includes: a touch sensing device 100, a first sensing element x, a plurality of second sensing elements y, a circuit board 103, and circuit connection lines (not shown in the figure). Among them, the circuit board 103 can be implemented by a flexible printed circuit board (PCB).

[0055] Please note that the features of the touch sensing device 100 are the same as those described above, and for the sake of brevity, they will not be described again here.

[0056] The first sensing element x is used to sense along a first axis, the second sensing element y is used to sense along a second axis, and the first sensing element x and the second sensing element y are arranged in an array; the circuit board 103 is coupled to the first sensing element x and the second sensing element y; the touch sensing device 100 is disposed between the first sensing element x, the second sensing element y, and the circuit board 103. The touch sensing device 100 is used to determine the coupling of the second sensing element y, and the coupling between the first common electrode E1 or the first conductive pattern 10 is determined by the circuit connection lines, that is, the coupling between the first common electrode E1 or the first conductive pattern 10 is used to determine the coupling of the second sensing element y.

[0057] In this embodiment, the first sensing element x is used to sense the X axis, and the second sensing element y is used to sense the Y axis. Here, please note that the lines connecting the second sensing element y to the touch sensing device 100 are re-routed through the touch sensing device 100, so the coupling method in the circuit connection chip 104 is different from the original lines of the second sensing element y.

[0058] For the sake of simplicity, in this embodiment, each group of sensing elements respectively has a first sensing element x and a plurality of second sensing elements y(0) to y(j - 1), which means Figure 2 FIG. shows the first sensing elements x(0) to x(3), and each of the first sensing elements x(0) to x(3) is paired with the second sensing elements y(0) to y(j - 1), and the sensing elements y(0) to y(j - 1) are arranged along the Y axis.

[0059] In one embodiment, each connection line is used to electrically connect the second sensing elements y having the same second coordinate position. That is to say, in this embodiment, each second sensing element y(0) is coupled, each second sensing element y(1) is coupled, each second sensing element y(2) is coupled, and each second sensing element y(j - 1) is coupled.

[0060] After the second sensing elements y(0) to y(j - 1) at the same second coordinate position are connected, the signals output by the second sensing elements y(0) to y(j - 1) are respectively transmitted to the circuit board 103 by the corresponding same signal transmission lines t(0) to t(j - 1). That is to say, the signal transmitted by the second sensing element y(0) is transmitted to the circuit board 103 through the signal transmission line t(0), and the same principle applies to the rest and will not be elaborated here. Where j is the number of signal transmission lines.

[0061] In the touch panel 200, each of the first sensing elements x(0) to x(3) is electrically connected to the touch sensing device 100, and the signals are respectively transmitted to the circuit board 103 by the corresponding signal transmission lines r(0) to r(3). In this way, through the circuit connection chip 104 of the present invention, the second sensing elements y(0) to y(j - 1) can be re-routed in the touch sensing device 100 to reduce the number of signal transmission lines t(0) to t(j - 1), so as to reduce the invisible area of the touch panel 200.

[0062] The first conductive pattern 10 is a touch sensing electrode (Rx) and the second conductive pattern 20 is a touch driving electrode (Tx) in an array form, and a mutual capacitance touch sensor capable of forming one or more capacitive nodes can be formed. The mutual capacitance touch sensor is in a single-layer configuration. In this single-layer configuration, the first conductive pattern 10 and the second conductive pattern 20 are respectively arranged on both sides of one of the arrays of the touch sensing device 100; in this configuration, a pair of driving and sensing electrodes that are capacitively coupled to each other across the space or dielectric between the electrodes can be regarded as a capacitive node. In a single-layer configuration for a self-capacitance implementation, each of the conductive electrodes in the array can form a capacitive node, and when an object touches or approaches the electrode, a change in self-capacitance can occur at that capacitive node, and a touch controller (not shown in the figure) can measure this change in capacitance as a touch sensing point.

[0063] In an embodiment, the touch sensing device 100 implements a capacitive form of touch sensing. In a mutual capacitance implementation, the touch sensing device 100 includes a capacitive node array formed by a driving and sensing electrode array (i.e., the first conductive pattern 10 and the second conductive pattern 20). Among them, a pair of driving and sensing electrodes can be regarded as a capacitive node. The driving and sensing electrodes of the capacitive node are close to each other, but do not make electrical contact with each other. Instead, the capacitive coupling generated between the driving and sensing electrodes across their gap induces charges on the sensing electrode by the pulse or alternating voltage of the controller. The amount of induced charge is vulnerable to external influences (such as an object touching or approaching).

[0064] When an object touches or approaches the capacitive node, a capacitance change occurs at the capacitive node, and the first sensing element x and the second sensing element y measure the capacitance change; by measuring the capacitance changes in the entire array, the first sensing element x and the second sensing element y determine the position of the touch or approach within the touch-sensitive area of the touch sensing device 100. In one embodiment, the first sensing element x and the second sensing element y are coupled to the first conductive pattern 10, and the signal transmission lines t(0) to t(j - 1) are coupled to the second conductive pattern 20 to transmit signals to the circuit board 103.

[0065] Please refer to Figure 4 , Figure 4 a partial schematic diagram showing the coupling between the touch sensing device 100 and the circuit board 103 in an embodiment; in this embodiment, the signal transmission lines t(0) to t(21) are coupled to the second conductive pattern 20, and the signal transmission lines r(0) to r(1) are coupled to the first conductive pattern 10, where GND represents ground.

[0066] In summary, for the touch sensing device of the present invention, due to the improvement of the conductive pattern, the area of the virtual conductive pattern can be increased and the area of the touch sensing electrode (Rx) can be reduced, so as to reduce the parasitic capacitance generated by the touch driving electrode (Tx) and the touch sensing electrode (Rx), and avoid the capacitance change of the induced charge due to the parasitic capacitance, so that the first sensing element x and the second sensing element y sense incorrect signals.
