Please refer to fig. 1, which is a schematic structural diagram of a touch panel according to an embodiment of the present invention.
A touch panel 10, comprising: the touch panel comprises a panel body 100, a plurality of first electrodes 200 and a plurality of second electrodes 300, wherein the first electrodes 200 and the second electrodes 300 are arranged on the panel body 100 in an interlaced manner, the first electrodes 200 and the second electrodes 300 are insulated from each other at staggered positions and in the vicinity of the interlaced positions, the first electrodes 200 and the second electrodes 300 are arranged at intervals, the panel body 100 is provided with a plurality of touch areas 400, each touch area 400 comprises at least one part of at least one first electrode 200 and at least one part of at least one second electrode 300, and the first electrodes 200 and the second electrodes 300 form sensing capacitors at the intersections; the touch area 400 includes a first touch area 410 and a second touch area 420, and a capacitance value of a sensing capacitor in the first touch area 410 is different from a capacitance value of a sensing capacitor in the second touch area 420, wherein one of the sensing capacitor in the first touch area 410 and the sensing capacitor in the second touch area 420 is a standard sensing capacitor.
In this embodiment, the capacitance value of the sensing capacitor is used as a criterion for determining the size of the touch sensing amount corresponding to the touch area, and the capacitance value of the sensing capacitor in the first touch area is different from the capacitance value of the sensing capacitor in the second touch area by adjusting the structures of the first electrode and the second electrode, so that the touch sensing amount of one of the first touch area and the second touch area is changed, thereby facilitating adjustment of the touch sensing amount of the specific area and realizing control of the touch sensitivity of the specific area. And the standard sensing capacitance is a sensing capacitance formed at the intersection of the first electrode and the second electrode before the touch induction quantity of the touch area is not changed.
In one embodiment, referring to fig. 1, each of the first electrodes 200 includes a plurality of first sense cells 210, the plurality of first sense cells 210 are sequentially connected, each of the second electrodes 300 includes a plurality of second sense cells 310, the plurality of second sense cells 310 are sequentially connected, at least one of the first sense cells 210 and at least one of the second sense cells 310 are disposed in each of the touch areas 400, and the first electrodes 200 and the second electrodes 300 form the sense capacitance between the first sense cells 210 and the second sense cells 310 at the intersections. In this embodiment, an intersection of the first electrode 200 and the second electrode 300 serves as a touch point of the touch panel, wherein the first electrode 200 and the second electrode 300 are disposed perpendicular to each other. In one embodiment, the first electrodes 200 are used as electrodes in an X-axis direction of the touch panel, the second electrodes 300 are used as electrodes in a Y-axis direction of the touch panel, and the X-axis and the Y-axis are perpendicular to each other, so that all touch points of the touch panel correspond to intersections of the first electrodes 200 and the second electrodes 300, and thus the intersections of the first electrodes 200 and the second electrodes 300 correspond to all touch points of the touch panel one to one, which facilitates accurate acquisition of touch points by a touch chip connected to the touch panel. The first sense cells 210 of each of the first electrodes 200 are arranged in a direction parallel to an X-axis, the second sense cells 310 of each of the second electrodes 300 are arranged in a direction parallel to a Y-axis, each of the touch areas 400 includes the first sense cells 210 and the second sense cells 310 arranged in a horizontal and vertical manner, each of the first sense cells 210 is adjacent to at least one of the second sense cells 310, two sensing capacitors are formed between the adjacent first sense cells 210 and the adjacent second sense cells 310, when a finger touches the touch panel, capacitance values of the sensing capacitors between the adjacent first sense cells 210 and the adjacent second sense cells 310 are changed, and thus when a finger touches the touch panel, touch sensing values between the adjacent first sense cells 210 and the adjacent second sense cells 310 are changed, therefore, the touch sensing quantity of the specific area can be adjusted conveniently, and the touch sensitivity of the specific area can be controlled. In one embodiment, at the intersection between each of the first electrodes 200 and the second electrodes 300, two adjacent first sense cells 210 are symmetrically disposed at the intersection, two adjacent second sense cells 310 are also symmetrically disposed at the intersection, and the first sense cells 210 are adjacent to the second sense cells 310, that is, each of the first sense cells 210 is adjacent to four second sense cells 310, that is, each of the second sense cells 310 is adjacent to four first sense cells 210, so that the first sense cells 210 and the second sense cells 310 are tiled on the touch panel, thereby reducing the thickness of the touch panel.
In one embodiment, referring to fig. 1, the number of the first sense cells 210 and the second sense cells 310 per unit touch area of the first touch area 410 is different from the number of the first sense cells 210 and the second sense cells 310 per unit touch area of the second touch area 420. For example, in the case that the pitches between the first sense cells 210 and the second sense cells 310 arranged adjacently are the same, when the touch sensing amount of the first touch area 410 needs to be increased, the number of the first sense cells 210 and the second sense cells 310 in the unit touch area of the first touch area 410 is smaller than the number of the first sense cells 210 and the second sense cells 310 in the unit touch area of the second touch area 420; for another example, when the first sense cells 210 and the second sense cells 310 arranged adjacently are spaced at the same interval, the number of the first sense cells 210 and the second sense cells 310 in the unit touch area of the first touch area 410 is greater than the number of the first sense cells 210 and the second sense cells 310 in the unit touch area of the second touch area 420 when the touch sensing amount of the first touch area 410 needs to be reduced. In this way, the area of the first sense cell 210 or the second sense cell 310 in the first touch area 410 is different from the area of the first sense cell 210 or the second sense cell 310 in the second touch area 420, so as to facilitate adjustment of the touch sensing amount of the first touch area 410, and further facilitate touch monitoring of the first touch area 410.
In one embodiment, the adjustment of the touch sensitivity of a certain touch area is facilitated by adjusting the capacitance of the sensing capacitor between the first sense cell 210 and the adjacent second sense cell 310, for example, the capacitance of the sensing capacitor between the first sense cell 210 and the adjacent second sense cell 310 is increased, so that the sensing capacitor of the touch area is increased, and thus when a finger touches the touch panel, the touch sensing amount of the touch area is increased, the touch sensitivity of the touch area is increased, and when a finger touches the touch panel, the touch of the touch area is more easily detected, so that the dead angle of the touch panel is more easily detected; for another example, the capacitance of the sensing capacitor between the first sensing cell 210 and the adjacent second sensing cell 310 is reduced, so that the sensing capacitor in the touch area is reduced, and thus when a finger touches the touch panel, the touch sensing amount in the touch area is reduced, and the touch sensitivity in the touch area is reduced, so that when a finger touches the touch panel, the touch in the touch area is not easily detected, and the touch sensing amount in the touch area, which is easily mistakenly touched to cause an erroneous operation, is reduced, and thus the unnecessary operation of triggering the touch panel due to the mistaken touch is reduced.
In one embodiment, referring to fig. 1, the area of the first sense cells 210 in the first touch area 410 is larger than the area of the first sense cells 210 in the second touch area 420. In the embodiment, since the human body is equivalent to a conductor and is in contact with the ground, the human finger is used as one pole of the sensing capacitor, and the capacitance formed by the finger and the first sensing cell 210 and the capacitance formed by the finger and the second sensing cell 310 are connected in parallel with each other, so as to form the sensing capacitor, i.e., the sensing capacitor is formed by the finger, the first sensing cell 210 and the adjacent second sensing cell 310. Mutual capacitance between the first sense cell 210 and the adjacent second sense cell 310 in each touch area 400 is the same, and only when a finger touches the touch panel, the capacitance value of the sense capacitance formed by the first sense cell 210 and the adjacent second sense cell 310 changes, so that whether touch occurs in the touch area is distinguished according to the change of the sensing amount of the sense capacitance, and thus touch monitoring on the touch panel is facilitated. In the case where the area of the first sense cells 210 within the first touch area 410 is greater than the area of the first sense cells 210 within the second touch area 420, it is indicated that the capacitance value of the capacitance between the first sense cell 210 and the finger of the human body in the first touch area 410 is greater than the capacitance value of the capacitance between the first sense cell 210 and the finger of the human body in the second touch area 420, which indicates that the capacitance value of the capacitance between the first sense cell 210 and the finger of the human body in the first touch area 410 is increased, such that the capacitance value of the sensing capacitance between the first sense cell 210 and the second sense cell 310 in the first touch area 410 is increased, when a finger touches the touch panel, the touch sensing amount in the first touch area 410 is increased, and the touch sensitivity of the first touch area 410 is improved. In one embodiment, the first touch area 410 is a touch area on the touch panel that is difficult to operate by touching a screen, that is, the first touch area 410 is an area with low touch sensitivity on the touch panel, the second touch area 420 is a normal touch area, and the normal touch area is a touch area with unchanged touch sensing amount. In one embodiment, the first touch area 410 is an edge area of the touch panel, and the second touch area 420 is a middle area of the touch panel, so that touch monitoring of the edge area of the touch panel is facilitated by increasing a touch sensing amount of the edge area of the touch panel, thereby increasing a touch response speed of the edge area of the touch panel.
In one embodiment, referring to fig. 1, the area of the second sense cells 310 in the first touch area 410 is larger than the area of the second sense cells 310 in the second touch area 420. In the embodiment, since the human body is equivalent to a conductor and is in contact with the ground, the human finger is used as one pole of the sensing capacitor, and the capacitance formed by the finger and the first sensing cell 210 and the capacitance formed by the finger and the second sensing cell 310 are connected in parallel with each other, so as to form the sensing capacitor, i.e., the sensing capacitor is formed by the finger, the first sensing cell 210 and the adjacent second sensing cell 310. Mutual capacitance between the first sense cell 210 and the adjacent second sense cell 310 in each touch area 400 is the same, and when a finger touches the touch panel, the capacitance value of the sense capacitance formed by the first sense cell 210 and the adjacent second sense cell 310 changes, so that whether touch occurs in the touch area is distinguished according to the change of the sensing amount of the sense capacitance, and thus touch monitoring of the touch panel is facilitated. In the case where the area of the second sense cells 310 in the first touch area 410 is greater than the area of the second sense cells 310 in the second touch area 420, it is indicated that the capacitance value of the capacitance between the second sense cell 310 and the finger of the human body in the first touch area 410 is greater than the capacitance value of the capacitance between the second sense cell 310 and the finger of the human body in the second touch area 420, which indicates that the capacitance value of the capacitance between the second sense cell 310 and the finger of the human body in the first touch area 410 is increased, such that the capacitance value of the sensing capacitance between the first sense cell 210 and the second sense cell 310 in the first touch area 410 is increased, when a finger touches the touch panel, the touch sensing amount in the first touch area 410 is increased, and the touch sensitivity of the first touch area 410 is improved. In one embodiment, the first touch area 410 is a touch area on the touch panel that is difficult to operate by touching a screen, that is, the first touch area 410 is an area with low touch sensitivity on the touch panel, the second touch area 420 is a normal touch area, and the normal touch area is a touch area with unchanged touch sensing amount. In one embodiment, the first touch area 410 is an edge area of the touch panel, and the second touch area 420 is a middle area of the touch panel, so that touch monitoring of the edge area of the touch panel is facilitated by increasing a touch sensing amount of the edge area of the touch panel, thereby increasing a touch response speed of the edge area of the touch panel.
In one embodiment, the area of the first sense cells 210 in the first touch area 410 is larger than the area of the first sense cells 210 in the second touch area 420, and the area of the second sense cells 310 in the first touch area 410 is larger than the area of the second sense cells 310 in the second touch area 420. In this way, the area of the first sense cell 210 and the area of the second sense cell 310 in the first touch area 410 are both larger than the area of the first sense cell 210 and the area of the second sense cell 310 in the second touch area 420, so that the unit touch area in the first touch area 410 is larger than the unit touch area of the second touch area 420, and thus under the condition that the number of the first sense cells 210 and the number of the second sense cells 310 are the same, the capacitance value of the sense capacitance of the first touch area 410 is larger than the capacitance value of the sense capacitance of the second touch area 420, and further under the condition that the number of the first sense cells 210 and the number of the second sense cells 310 are the same, the touch sensing amount of the first touch area 410 is larger than the touch sensing amount of the second touch area 420, thereby further facilitating the touch monitoring of the edge area of the touch panel, thereby further improving the touch response speed to the edge area of the touch panel.
In one embodiment, the area of the first sense cells in the first touch area is smaller than the area of the first sense cells in the second touch area. In this embodiment, since the human body is equivalent to the conductor and is in contact with the ground, the human finger is used as one electrode of the sensing capacitor, and the capacitance formed by the finger and the first and second sensing cells is connected in parallel with the mutual capacitance, so as to form the sensing capacitor, that is, the sensing capacitor is formed by the finger, the first sensing cell and the adjacent second sensing cell. Mutual capacitance between the first sense cell and the adjacent second sense cell in each touch area is the same, and when a finger touches the touch panel, the capacitance value of the sense capacitance formed by the first sense cell and the adjacent second sense cell changes, so that whether touch occurs in the touch area can be conveniently distinguished according to the change of the sensing quantity of the sense capacitance, and therefore touch monitoring on the touch panel is facilitated. In the case where the area of the first sense cells within the first touch area is smaller than the area of the first sense cells within the second touch area, indicating that the capacitance value of the capacitance between the first sense cell and the finger of the human body in the first touch area is smaller than the capacitance value of the capacitance between the first sense cell and the finger of the human body in the second touch area, which means that the capacitance of the capacitor between the first sense cell and the finger of the human body in the first touch area is reduced, thereby reducing a capacitance value of a sensing capacitance between the first sense cell and the second sense cell within the first touch area, when a finger touches the touch panel, the touch induction quantity in the first touch area is reduced, and the touch sensitivity of the first touch area is reduced, so that misoperation caused by the fact that the finger touches the first touch area by mistake is reduced. In one embodiment, the first touch area is an erroneous operation that is likely to pass through a touch screen on the touch panel, that is, the first touch area is an area with higher touch sensitivity on the touch panel, the second touch area is a normal touch area, and the normal touch area is a touch area with unchanged touch sensing amount. In one embodiment, the first touch area is an edge area of the touch panel, and the second touch area is a middle area of the touch panel, so that touch monitoring of the edge area of the touch panel is facilitated by reducing touch induction quantity of the edge area of the touch panel, thereby reducing touch response speed of the edge area of the touch panel, and further reducing misoperation of mistakenly touching the edge area of the touch panel.
In one embodiment, the area of the second sense cells in the first touch area is smaller than the area of the second sense cells in the second touch area. In this embodiment, since the human body is equivalent to the conductor and is in contact with the ground, the human finger is used as one electrode of the sensing capacitor, and the capacitance formed by the finger and the first and second sensing cells is connected in parallel with the mutual capacitance, so as to form the sensing capacitor, that is, the sensing capacitor is formed by the finger, the first sensing cell and the adjacent second sensing cell. Mutual capacitance between the first sense cell and the adjacent second sense cell in each touch area is the same, and when a finger touches the touch panel, the capacitance value of the sense capacitance formed by the first sense cell and the adjacent second sense cell changes, so that whether touch occurs in the touch area can be conveniently distinguished according to the change of the sensing quantity of the sense capacitance, and therefore touch monitoring on the touch panel is facilitated. In the case where the area of the second sense cells within the first touch area is smaller than the area of the second sense cells within the second touch area, indicating that the capacitance value of the capacitance between the second sense cell in the first touch area and the finger of the human body is smaller than the capacitance value of the capacitance between the second sense cell in the second touch area and the finger of the human body, namely, it indicates that the capacitance value of the capacitance between the second sense cell and the finger of the human body in the first touch area is reduced, thereby reducing a capacitance value of a sensing capacitance between the first sense cell and the second sense cell within the first touch area, when a finger touches the touch panel, the touch induction quantity in the first touch area is reduced, and the touch sensitivity of the first touch area is reduced, so that misoperation caused by the fact that the finger touches the first touch area by mistake is reduced. In one embodiment, the first touch area is an erroneous operation that is likely to pass through a touch screen on the touch panel, that is, the first touch area is an area with higher touch sensitivity on the touch panel, the second touch area is a normal touch area, and the normal touch area is a touch area with unchanged touch sensing amount. In one embodiment, the first touch area is an edge area of the touch panel, and the second touch area is a middle area of the touch panel, so that touch monitoring of the edge area of the touch panel is facilitated by reducing touch induction quantity of the edge area of the touch panel, thereby reducing touch response speed of the edge area of the touch panel, and further reducing misoperation of mistakenly touching the edge area of the touch panel.
