Description

Technical Field

[0001] This invention relates to an electronic device, and more particularly to a touch device and its touch panel. Background Technology

[0002] Generally, touch panels have multiple sensing electrodes. These electrodes are used to sense touch events. Multiple analog-to-digital converters (ADCs) in the touch driver are used to convert the sensing signals (touch sensing results) from these electrodes into digital data. To reduce circuit costs, touch drivers typically use a smaller number of ADCs to process the sensing signals from a larger number of electrodes in a time-sharing, multi-tasking manner. For example, if a touch panel has 128 sensing electrodes and the touch driver has 64 ADCs, these 64 ADCs need to perform two read operations (conversion operations) at different times to convert the sensing signals from the 128 electrodes into digital data. In other words, these 64 ADCs take two units of time to convert the sensing signals from the 128 electrodes into digital data. Reducing the number of ADCs means that the processing time of the touch driver will increase.

[0003] It should be noted that the content of the "Background Art" paragraph is used to help understand the present invention. Some (or all) of the content disclosed in the "Background Art" paragraph may not be publicly known to those skilled in the art. The content disclosed in the "Background Art" paragraph does not imply that such content was known to those skilled in the art prior to this application. Summary of the Invention

[0004] The present invention provides a touch device and its touch panel, which can reduce the number of reads of the touch panel when the number of analog-to-digital converters (ADCs) of the touch driver is limited, that is, when the number of pins of the touch driver is limited (or can reduce the number of pins of the touch driver when the number of reads of the touch panel is limited).

[0005] In one embodiment of the invention, the touch panel includes a plurality of pads and a plurality of sensing electrodes. These pads are adapted to be electrically connected to different pins of a touch driving device. These sensing electrodes are adapted to sense touch events of the touch panel. Any column of these sensing electrodes includes a plurality of sensing electrode groups. Multiple sensing electrodes belonging to any sensing electrode group are coupled to a corresponding pad among these pads. The sensing electrodes of each sensing electrode group in the same column are distributed throughout the same column. The arrangement of these sensing electrode groups differs in any column from the arrangement in an adjacent column adjacent to any column.

[0006] In one embodiment of the present invention, the aforementioned touch device includes a touch panel and a touch driving device. The touch panel includes a plurality of pads and a plurality of sensing electrodes. These sensing electrodes are adapted to sense touch events on the touch panel. Any column of these sensing electrodes includes a plurality of sensing electrode groups. A plurality of sensing electrodes belonging to any sensing electrode group are coupled to a corresponding pad in one of the pads. The sensing electrodes of each sensing electrode group in the same column are distributed within the same column. The arrangement of these sensing electrode groups differs in any column from the arrangement in an adjacent column. The touch driving device includes a plurality of pins electrically connected to the pads. The touch driving device converts multiple touch sensing results received by these pins into multiple touch sensing data. When the current touch sensing data in these touch sensing data indicates that "a touch event has occurred in a current sensing electrode group corresponding to the current touch sensing data" in these sensing electrode groups, the touch driving device checks whether at least one first adjacent sensing electrode that is adjacent to the first current sensing electrode of the current sensing electrode group has also experienced a touch event in order to determine whether a touch event has occurred in the first current sensing electrode.

[0007] Based on the above, the multiple sensing electrodes of the touch panel described in the embodiments of the present invention can be divided into multiple columns, and each column includes multiple groups of sensing electrodes. Multiple sensing electrodes belonging to the same group of sensing electrodes can be coupled to the same pad. Therefore, when the number of analog-to-digital converters in the touch driver is limited, that is, when the number of pins in the touch driver is limited, the number of reads of the touch panel can be effectively reduced. Alternatively, when the number of reads of the touch panel is limited, the number of pins in the touch driver (i.e., the number of pads in the touch panel) can be effectively reduced.

[0024] Figure 1 This is a schematic diagram of a circuit block of a touch device 100 according to an embodiment of the present invention. Figure 1 The touch device 100 shown includes a touch panel 110 and a touch driving device 120. The touch panel 110 has a plurality of sensing electrodes (i.e., an array of sensing electrodes), for example... Figure 1 The sensing electrode SE shown 1,1 SE 1,2 SE 1,n SE 2,1 SE 2,2 SE 2,n SE m,1 SE m,2 SE m,n These sensing electrodes SE 1,1 ~SE m,n Suitable for sensing touch events on the touch panel 110. These sensing electrodes SE 1,1 ~SE m,n The number of columns, *m*, and the number of rows, *n*, are integers determined by the actual design. It should be noted that... Figure 1 The sensing electrode SE shown 1,1 ~SE m,n Although the geometry is rectangular, in other embodiments the sensing electrode SE 1,1 ~SE m,n The geometry can be any other shape determined by the actual design. Furthermore, the sensing electrode SE... 1,1 ~SE m,n The layout (i.e., the geometry of the sensing electrode array) can also be determined according to the actual design.

[0025] This embodiment does not limit the implementation and details of the touch panel 110. For example, in some embodiments, the touch panel 110 may be an in-cell touch display panel or other touch panels. In some embodiments, the common voltage electrode of the in-cell touch display panel may be divided into multiple sub-electrodes, and these sub-electrodes may be used as sensing electrodes SE. 1,1 ~SE m,n .

[0026] The touch panel 110 also includes multiple pads, such as Figure 1 The pads PAD_1, ..., PAD_p are shown. These pads PAD_1 to PAD_p are adapted to be electrically connected to different pins of the touch driver 120, for example... Figure 1 The pins shown are PIN_1, ..., PIN_p. The number p of these pads PAD_1 to PAD_p (i.e., the number of pins PIN_1 to PIN_p) is an integer determined according to the actual design, and p is less than the number of sensing electrodes SE. 1,1 ~SE m,n The number of pads is m*n. For example, assuming the touch panel 110 has 128 sensing electrodes, and assuming each sensing electrode group has two sensing electrodes, then the number p of these pads PAD_1 to PAD_p can be 64. Assuming each sensing electrode group has four sensing electrodes, then the number p of these pads PAD_1 to PAD_p can be 32.

[0027] The touch driver 120 also includes multiple analog-to-digital converters (ADCs), such as... Figure 1 The analog-to-digital converters ADC_1, ..., ADC_p are shown. The input terminals of ADC_1 to ADC_p are connected to pins PAD_1 to PAD_p, respectively. ADC_1 to ADC_p can convert multiple touch sensing results (analog signals) received from these pins PAD_1 to PAD_p into multiple touch sensing data (digital data).

[0028] exist Figure 1 In the illustrated embodiment, these sensing electrodes SE 1,1 ~SE m,n It has m columns, where any column contains multiple sensing electrode groups. The number of sensing electrodes in each sensing electrode group can be determined according to the actual design. These sensing electrodes SE 1,1 ~SE m,nIn this configuration, all sensing electrodes belonging to the same sensing electrode group are commonly coupled to a corresponding pad among these pads PAD_1 to PAD_p. For example, assuming each sensing electrode group has two sensing electrodes, then the sensing electrodes SE belonging to the same sensing electrode group... 1,1 With sensing electrode SE 1,j (j is an integer between 1 and n) are commonly coupled to pad PAD_1, while the sensing electrodes SE, belonging to another group of sensing electrodes, are... m,2 With sensing electrode SE m,k (k is an integer between 1 and n) are jointly coupled to pad PAD_p.

[0029] The sensing electrodes of each sensing electrode group in the same column are distributed within that same column. That is, all sensing electrodes belonging to the same sensing electrode group are not adjacent to each other. For example, using... Figure 1 For example, sensing electrodes SE belonging to the same sensing electrode group 1,1 With sensing electrode SE 1,j The positions in the first column are dispersed (sensing electrodes SE). 1,1 Non-adjacent sensing electrode SE 1,j The sensing electrode SE, belonging to another group of sensing electrodes, m,2 With sensing electrode SE m,k The positions in the m-th column are scattered (sensing electrode SE). m,2 Non-adjacent sensing electrode SE m,k ).

[0030] Furthermore, in these sensing electrodes SE 1,1 ~SE m,n The arrangement of these sensing electrode groups in any column differs from the arrangement of these sensing electrode groups in an adjacent column. For example, with Figure 1 For example, in these sensing electrodes SE 1,1 ~SE m,n The arrangement of these sensing electrode groups in the first column is different from that in the second column (adjacent columns).

[0031] For example, Figure 2 This is described according to an embodiment of the present invention. Figure 1 A schematic diagram showing the layout of the sensing electrodes in the touch panel 110. Figure 2 In the illustrated embodiment, the touch panel 110 is assumed to have 128 sensing electrodes (i.e., 8 / 16 sensing electrodes SE). 1,1 ~SE 8,16The touch panel 110 is assumed to have 64 pads PAD_1 to PAD_64 (i.e., p = 64). In the case where the touch panel 110 is an embedded touch display panel, these sensing electrodes SE 1,1 ~SE 8,16 It can be used as a common voltage electrode for in-wall touch display panels during display driving. Figure 2 In the illustrated embodiment, these sensing electrodes SE of the touch panel 110 1,1 ~SE 8,16 It is divided into 8 columns (i.e., m=8), with 16 sensing electrodes in each column (i.e., n=16).

[0032] These sensing electrodes SE 1,1 ~SE 8,16 Each column contains multiple sensing electrode groups. The number of sensing electrodes in each sensing electrode group can be determined according to the actual design. Figure 2 In the illustrated embodiment, each group of sensing electrodes has two sensing electrodes. Figure 2 In the diagram, the number in parentheses for each sensing electrode indicates the sensing electrode group to which that electrode belongs. For example, Figure 2 The sensing electrode SE shown 1,2 with SE 1,11 All are marked with "2", indicating that the sensing electrode SE 1,2 with SE 1,11 All belong to the same sensing electrode group (hereafter referred to as the second sensing electrode group as indicated by "2"). These sensing electrodes of each sensing electrode group in the same column are distributed within the same column. All sensing electrodes belonging to the same sensing electrode group are not adjacent to each other. Furthermore, in these sensing electrodes SE 1,1 ~SE 8,16 The arrangement of these sensing electrode groups in any column differs from the arrangement of these sensing electrode groups in an adjacent column. For example, with Figure 1 For example, in these sensing electrodes SE 1,1 ~SE 8,16 The arrangement of these sensing electrode groups in the first column is different from that in the second column (adjacent columns).

[0033] In these sensing electrodes SE 1,1 ~SE 8,16 In this configuration, all sensing electrodes belonging to the same sensing electrode group are commonly coupled to a corresponding pad among these pads PAD_1 to PAD_64. For example, sensing electrode SE belonging to the first sensing electrode group... 1,1 with SE 1,9 The sensing electrode SE, which is commonly coupled to the pad PAD_1, belongs to the second group of sensing electrodes.1,2 with SE 1,11 The sensing electrode SE, which is commonly coupled to pad PAD_2, belongs to the 63rd sensing electrode group. 8,1 with SE 8,11 They are all coupled to pad PAD_63, while the sensing electrode SE, belonging to the 64th sensing electrode group, is... 8,3 With sensing electrode SE 8,12 They are all coupled to pad PAD_64. The remaining sensing electrode groups follow the same principle.

[0034] Please refer to Figure 1 and Figure 2 The 64 pins PIN_1 to PIN_64 (i.e., p=64) of the touch driver 120 are electrically connected to the 64 pads PAD_1 to PAD_64 of the touch panel 110. The touch driver 120 can convert multiple touch sensing results received from these pins PIN_1 to PIN_64 into multiple touch sensing data. The touch driver 120 can check these touch sensing data to determine whether a touch event has occurred on the touch panel 110. For example, when the touch sensing data corresponding to pad PAD_1 is greater than a threshold, the touch driver 120 can determine the first sensing electrode group (i.e., sensing electrode SE). 1,1 with SE 1,9 A touch event occurred.

[0035] If one of the current touch sensing data indicates that "the touch event occurred in the current sensing electrode group corresponding to this current touch sensing data" among these sensing electrode groups, the touch driver 120 can check these sensing electrodes SE 1,1 ~SE 8,16 The touch driver 120 determines whether a touch event has occurred on the first current sensing electrode by checking whether at least one sensing electrode adjacent to one of the sensing electrodes in the current sensing electrode group (e.g., referred to as the first current sensing electrode) also experiences a touch event. For example, if the current touch sensing data indicates a touch event has occurred, and if the first adjacent sensing electrode also experiences a touch event, the touch driver 120 can determine that a touch event has occurred on the first current sensing electrode. Conversely, if the current touch sensing data indicates a touch event has occurred, and if the first adjacent sensing electrode does not experience a touch event, the touch driver 120 can determine that no touch event has occurred on the first current sensing electrode.

[0036] Suppose an object (such as a finger or active stylus) touches the sensing electrodes SE of the touch panel 110. 4,4 Sensing electrodes SE belonging to the same sensing electrode group 4,4 With sensing electrode SE4,8 They are all coupled to the same pad PAD_28, which is the sensing electrode SE. 4,4 with SE 4,8 All have the same touch sensing data. The touch driver 120 can determine the sensing electrode SE based on the touch sensing data. 4,4 with SE 4,8 One of them experiences a touch event. This occurs when the object touches the sensing electrode SE. 4,4 At that time, in addition to the sensing electrode SE 4,4 In addition to being able to determine that a touch event has occurred, the sensing electrode SE 4,8 A touch event may be mistakenly identified. To eliminate false positives, the touch driver 120 can further inspect the sensing electrode SE. 4,4 adjacent sensing electrode SE 3,4 SE 4,3 SE 4,5 with SE 5,4 With / or sensing electrode SE 4,8 adjacent sensing electrode SE 3,8 SE 4,7 SE 4,9 with SE 5,8 .

[0037] Assuming the object touches the sensing electrode SE of the touch panel 110 4,4 Touching the object will affect the sensing electrode SE. 4,4 adjacent sensing electrode SE 3,4 SE 4,3 SE 4,5 with SE 5,4 Even adjacent sensing electrodes SE 3,4 SE 4,3 SE 4,5 with SE 5,4 The touch sensing data is greater than the threshold. That is, when an object touches the sensing electrode SE... 4,4 At that time, in addition to the sensing electrode SE 4,4 A touch event is detected, and the sensing electrode SE 3,4 SE 4,3 SE 4,5 with SE 5,4 A touch event is also detected. Therefore, the touch driver 120 can check the sensing electrodes SE of the current sensing electrode group. 4,4 (First current sensing electrode) adjacent sensing electrode SE 3,4 SE 4,3 SE 4,5 With / or SE 5,4 Did a touch event also occur at (the first adjacent sensing electrode)? Based on the current touch sensing data, the sensing electrode SE...4,4 In the event of a touch event, and in the case of adjacent sensing electrodes SE 3,4 SE 4,3 SE 4,5 With / or SE 5,4 In the event of a touch event, the touch driver 120 can determine the sensing electrode SE. 4,4 A touch event has occurred.

[0038] Conversely, the sensing electrodes SE belonging to the same sensing electrode group 4,8 (The second current sensing electrode of the current sensing electrode group), because the object does not actually touch the SE. 4,8 Therefore, the adjacent sensing electrode SE 3,8 SE 4,7 SE 4,9 with SE 5,8 The touch sensing data will not exceed the threshold (i.e., the sensing electrode SE). 3,8 SE 4,7 SE 4,9 with SE 5,8 (No touch event was determined to have occurred). Current touch sensing data indicates that the sensing electrode SE... 4,4 with SE 4,8 In the event of a touch event, in addition to checking the sensing electrode SE 4,4 adjacent sensing electrode SE 3,4 SE 4,3 SE 4,5 with SE 5,4 The touch driver 120 can also check the sensing electrode SE. 4,8 adjacent sensing electrode SE 3,8 SE 4,7 SE 4,9 with SE 5,8 To determine whether a touch event also occurs, the sensing electrode SE is used. 4,4 or SE 4,8 Did a touch event occur?

[0039] In the current touch sensing data representation, the sensing electrode SE 4,4 with SE 4,8 In the event of a touch event, and in the case of adjacent sensing electrodes SE 3,8 SE 4,7 SE 4,9 with SE 5,8 In the absence of a touch event, the touch driver 120 can determine the sensing electrode SE. 4,8 No touch event occurred. Alternatively, based on the current touch sensing data, the sensing electrode SE... 4,4 with SE 4,8In the event of a touch event, and in the current sensing electrode group, the sensing electrode SE 4,8 If it is determined that no touch event has occurred, the touch driver 120 can determine the current sensing electrode SE of the sensing electrode group. 4,4 The touch event occurred. This was determined by the sensing electrode SE. 4,4 After the touch event occurs, the touch driver 120 can determine the location of the touch based on the sensing electrode SE. 4,4 SE 3,4 SE 4,3 SE 4,5 with SE 5,4 The size of the touch sensor data determines the touch position of the object.

Figure 1 and Figure 2 The descriptions of the touch device 100, touch panel 110, and touch driver 120 shown are analogous and will not be repeated here. Unlike Figure 1 The touch panel 110 shown is located at, Figure 3 The touch panel 310 shown also includes a routing circuit 311. The routing circuit 311 has multiple selection terminals coupled to these sensing electrodes SE. 1,1 ~SE m,n The routing circuit 311 has multiple common terminals coupled to these pads PAD_1 to PAD_p. The routing circuit 311 is configured to selectively couple multiple sensing electrodes belonging to the same sensing electrode group to a corresponding pad among these pads PAD_1 to PAD_p. For example, these pads PAD_1 to PAD_p operate in one of multiple modes under the control signals MUX1 and MUX2.

Figure 5 The horizontal axis shown represents time. Please refer to... Figure 3 and Figure 5 In the second operating mode, all sensing electrodes belonging to the same sensing electrode group are coupled to the same corresponding pad at the same time.

[0044] In summary, the multiple sensing electrodes SE of the touch panel 110 (or 310) described in the above embodiments... 1,1 ~SE m,nIt can be divided into m columns, and any column includes multiple groups of sensing electrodes. For example, in Figure 2 Each sensing electrode SE shown 1,1 ~SE 8,16 In the diagram, the numbers in parentheses represent the schematic symbols for the sensing electrode group. Multiple sensing electrodes belonging to the same sensing electrode group can be coupled to the same pad. Therefore, when the number of analog-to-digital converters in the touch driver 120 (or 320) is limited, that is, when the number of pins PIN_1 to PIN_p in the touch driver 120 (or 320) is limited, the number of reads of the touch panel 110 (or 310) by the touch driver 120 (or 320) can be effectively reduced. Alternatively, when the number of reads of the touch panel 110 (or 310) is limited, the number of pins PIN_1 to PIN_p in the touch driver 120 (or 320) (that is, the number of pads PAD_1 to PAD_p in the touch panel) can be effectively reduced.
