In addition, in the description of the present application, "a plurality" means two or more unless otherwise specified.
The application provides a large-size capacitive touch screen, which has a structure as shown in fig. 1, and comprises a front protection panel 100, a first induction layer 200, a second induction layer 300, a liquid crystal display layer 400, a shielding layer 500 and a rear protection panel 600, which are sequentially attached from front to back, wherein "front" refers to the side facing the touch screen when a user normally uses the touch screen, and the layers are bonded and connected through an optical adhesive layer 700. The front protection panel 100 and the rear protection panel 600 are generally made of glass or plastic, the front protection panel 100 is used to prevent the touch panel from being damaged when a user writes, the rear protection panel 600 is used to protect the liquid crystal display layer 400, the shielding layer 500 is used to shield interference signals from a power board on the whole machine and the external environment, and the optical adhesive layer 700 may be optical adhesive made of any material, such as oca (optical Clear adhesive) optical adhesive. The first and second sensing layers 200 and 300 may be any material that facilitates the formation of pattern channels by etching, and typically an ITO (indium tin oxide) material is used.
The first sensing layer 200 includes a first sensing layer pattern channel (not shown) and a first sensing layer electrode line (not shown), as shown in fig. 2, the second sensing layer 300 includes a second sensing layer pattern channel 301 and second sensing layer electrode lines 302, a first sensing layer pattern channel and first sensing layer electrode lines, and the second sensing layer pattern channel 301 and the second sensing layer electrode line 302 can be connected by etching, the first sensing layer 200 is used as a driving electrode, the second sensing layer 300 is used as a receiving electrode, the first sensing layer channel can be a pattern channel of an X axis, then the second sense layer channel 301 is a pattern channel of the Y-axis, and may also be a pattern channel of the first sense layer channel of the Y-axis, the second sense layer channel 301 is a patterned channel with an X-axis, where it is understood that the X-axis is a horizontally extending axis and the Y-axis is a vertically extending axis. A node capacitance is formed at the intersection point of the first sensing layer graphic channel and the second sensing layer graphic channel 301, when a capacitive pen or a finger touches the capacitive screen, the node capacitance is caused to change, the changed capacitance value is transmitted to the touch IC module 802 of the capacitive touch screen control panel 800 through the second sensing layer electrode line 302, and the touch point position coordinate corresponding to the changed capacitance value is calculated through the touch IC module 802.
As shown in fig. 2, the capacitive touch screen control board 800 further includes an intelligent switch 801, where the intelligent switch 801 is configured to connect the second sensing layer graphic channel 301 to the touch IC module 802, specifically, the touch IC module 802 has m channels, a first end of the intelligent switch 801 includes N first pins, which are respectively connected to N second sensing layer electrode lines 302 of the second sensing layer 300, a second end of the intelligent switch 801 includes m second pins, which are respectively connected to m channels of the touch IC module 802, and m is less than N. The m second pins of the second end of the intelligent switch 801 can be sequentially connected to a portion of the first pins of the first end, so that the m channels of the touch IC module 802 can traverse the N second sensing layer graphics channels 301 of the second sensing layer 300. Thus, the second sensing layer graphic channel 301 and the touch IC module 802 are selected by the intelligent selection switch 801 in time-sharing and sequentially gated in turn, so that the touch IC module 802 with the maximum touch channel number of m controls the capacitive touch screen with the sensing layer graphic channel number of N (N > m), the problem that the large-size touch screen is limited by touch IC channel resources is solved, the larger-size capacitive touch screen is developed by using the limited touch IC channel resources on the premise of ensuring the high performance of the large-size touch screen, and the production cost and the development cost of the large-size capacitive touch screen are reduced while the touch IC channel resources are saved.
The specific gating control process is that when N is less than or equal to 2m, the intelligent selection switch 801 selects the 1 st to m first pins of the first end to be connected with the 1 st to m second pins of the second end in a first time period, so that the 1 st to m channels of the touch IC module 802 and the 1 st to m second induction layer graphic channels 301 of the second induction layer 300 are gated, and touch control is realized in a display area where the 1 st to m second induction layer graphic channels 301 are located; the intelligent selection switch 801 selects the (m + 1-N) th first pins of the first end to be connected with the (1-N-m) th second pins of the second end in the second time period, so that the (1-N-m) th channels of the touch IC module 802 are gated with the (m + 1-N) th second induction layer graphic channels 301 of the second induction layer 300, and touch control is realized in the display area where the (m + 1-N) th second induction layer graphic channels 301 are located; by circularly scanning the second sensing layer graphic channels 301 which are communicated in the first time period and the second time period, the 1 st to m second sensing layer graphic channels 301 and the m +1 th to N second sensing layer graphic channels 301 of the second sensing layer 300 are respectively communicated with the channels of the touch IC module 800 in turn, so that full-screen touch of the touch screen is realized.
When N is greater than 2m, the intelligent selection switch 801 selects the 1 st to m first pins of the first end to be connected with the 1 st to m second pins of the second end in a first time period, so that the 1 st to m channels of the touch IC module 802 are gated with the 1 st to m second induction layer graphic channels 301 of the second induction layer 300, and touch control is realized in a display area where the 1 st to m second induction layer graphic channels 301 are located; the intelligent selection switch 801 selects the (m + 1-2) th first pin of the first end to be connected with the (1-m) th second pin of the second end in the second time period, so that the (1-m) th channel of the touch IC module 802 is gated with the (m + 1-2 m) th second induction layer graphic channel 301 of the second induction layer 300, and touch control is realized in a display area where the (m + 1-2 m) th second induction layer graphic channel 301 is located; and repeating the steps until all the second induction layer graphic channels 301 are scanned, so that touch control on the full screen of the touch screen is realized.
Wherein, N first pins and N second induction layer electrode lines 302 can adopt arbitrary rule to connect, for example, N first pins are first pin 1 that arranges in proper order at intelligent change over switch 801's first end, …, first pin m, …, first pin N, N second induction layer electrode lines 302 are including the electrode line 1 that arranges in proper order, …, electrode line m, …, electrode line N, intelligent change over switch 801 includes control module, m second pins that control module control second end put through the first pin of part of first end in proper order by first pin 1 to first pin N, N second induction layer electrode lines 302 are continuous with N first pins according to following rule:
Because the second pins in the intelligent selection switch 801 are sequentially connected with the first pins, if the connection is performed according to the above rule, the scanning mode is block scanning, for example, when N is less than or equal to 2m, the scanning mode is switched between the region where the 1 st to m second sensing layer graphic channels 301 are located and the region where the m +1 th to N second sensing layer graphic channels 301 are located, if the user scans the region where the m +1 th to N second sensing layer graphic channels 301 are located when touching the region where the 1 st to m second sensing layer graphic channels 301 are located, touch failure may be caused, and therefore, the scanning mode may affect the touch accuracy and the touch reliability.
In order to solve the above problem, in a preferred embodiment, N second sensing layer electrode lines 301 are connected to the N first pins according to the following rule:
The interleaving scanning can be realized when the wiring is performed according to the above rule, for example, when N is 2m, the second sensing layer pattern channel 302 connected to the second sensing layer electrode line 301 with the odd label is scanned in the first time period, and the second sensing layer pattern channel 302 connected to the second sensing layer electrode line 301 with the even label is scanned in the second time period, so that a larger scanning area is covered in one time period as much as possible, and the touch failure can be effectively avoided.
In an alternative embodiment, N second sensing layer electrode lines 301 are connected to N first pins according to the following rule:
The interleaving scanning can also be implemented when the wiring is performed according to the above-mentioned rule, for example, when N is 2m, the second sensing layer pattern channel 302 connected to the second sensing layer electrode line 301 with the even number is scanned in the first period, and the second sensing layer pattern channel 302 connected to the second sensing layer electrode line 301 with the odd number is scanned in the second period.
Although the above wiring method can achieve the effect of avoiding touch failure, all electrode lines of the two wiring methods are not connected to the first pins corresponding to the numbers, and wiring is troublesome, and for this problem, in a further preferred embodiment, the N second sensing layer electrode lines 301 are connected to the N first pins according to the following rule:
electrode wires with odd numbers are correspondingly connected with the first pins, when N is an even number, the electrode wires 2 are connected with the first pins N, the electrodes 4 are connected with the first pins N-2, …, the electrodes N are connected with the first pins 2, when N is an odd number, the electrode wires 2 are connected with the first pins N-1, the electrodes 4 are connected with the first pins N-3, …, and the electrodes N-1 are connected with the first pins 2.
Therefore, the electrode wires with odd numbers are correspondingly connected with the first pins, that is, the electrode wires O are connected with the first pins O, for example, the electrode wires 1 are connected with the first pins 1, the electrode wires 3 are connected with the first pins 3, and the electrode wires 5 are connected with the first pins 5, …, wherein O is an odd number, which can simplify the wiring operation process to a certain extent.
In an alternative embodiment, the N second sensing layer electrode lines 301 may also be connected to the N first pins according to the following rule:
the electrode wires with even numbers are correspondingly connected with the first pins, and when N is an even number, the electrode wires 1 are connected with the first pins
The first pin N-1 is connected, the electrode 3 is connected with the first pin N-3, …, the electrode N-1 is connected with the first pin 2, when N is an odd number, the electrode wire 1 is connected with the first pin N, the electrode wire 3 is connected with the first pin N-2, …, and the electrode N is connected with the first pin 2.
Therefore, the electrode wires with even numbers are correspondingly connected with the first pins, that is, the electrode wires E are connected with the first pins E, for example, the electrode wires 2 are connected with the first pins 2, the electrode wires 4 are connected with the first pins 4, and the electrode wires 6 are connected with the first pins 6, …, wherein E is an even number, so that the wiring operation process can be simplified to a certain extent.
Of course, it can be understood that the penetrating scanning of the second sensing layer pattern channel 302 can also be realized by changing a program built in a control module of the intelligent switch 801 without changing the wiring manner of the N second sensing layer electrode lines 301 and the N first pins, that is, the two electrodes are wired in a manner corresponding to the numbers one to one.
Further, m second pins are a second pin 1, a second pin 2, …, and a second pin m sequentially arranged at the second end of the intelligent switch 801, m channels are a channel 1, a channel 2, a channel …, and a channel m sequentially arranged, and m second pins are connected with m channels according to the following rules:
