The directional terms mentioned in the present invention, such as [ upper ], [ lower ], [ front ], [ rear ], [ left ], [ right ], [ inner ], [ outer ], [ side ], are only referring to the directions of the attached drawings. Accordingly, the directional terms used are used for explanation and understanding of the present invention, and are not used for limiting the present invention.
In the drawings, elements having similar structures are denoted by the same reference numerals.
Referring to fig. 1, fig. 1 is a block diagram illustrating an embodiment of an integrated circuit architecture for gate scan touch scan according to the present invention, wherein the integrated circuit architecture 10 for gate scan touch scan is configured to complete multiple touch scans in one frame.
The gate scan touch scan integrated circuit architecture 10 includes a first cascaded gate scan circuit 100 including a plurality of cascaded first gate scan cells Goa 11-Goa 1n, and the first cascaded gate scan circuit 100 is configured to receive a first start signal STV1 and output a plurality of first scan signals G11-G1 n in a cascaded sequence, wherein the first cascaded gate scan circuit 100 is configured to output a first touch start signal Tp1 after outputting a last stage of the first scan signals G1 n; the first touch module 300 is configured to perform touch scanning after receiving the first touch start signal Tp 1; the second cascaded gate scan circuit 200 is connected to the first cascaded gate scan circuit 100 and includes a plurality of cascaded second gate scan cells Goa 21-Goa 2n, the second cascaded gate scan circuit 200 is configured to receive the second start signal STV2 and output a plurality of second cascaded scan signals G21-G2 n in a cascaded sequence, and the second cascaded gate scan circuit 200 is configured to output the last second scan signal G2b and output a second touch start signal Tp 2; and a second touch module 400 configured to perform touch scanning after receiving a second touch enable signal Tp 2.
It should be noted that in the integrated circuit architecture 10 for gate scan touch scan of the present invention, the first start signal STV1 and the second start signal STV2 are respectively input to the first cascaded gate scan circuit 100 and the second cascaded gate scan circuit 200 through the first trace R1 and the second trace R2.
Since the gate scan touch scan integrated circuit architecture 10 has different timings for activating the first cascaded gate scan circuit 100 and the second cascaded gate scan circuit 200, the timings for outputting the first start signal STV1 and the second start signal STV2 are different; by respectively using the first wire R1 and the second wire R2 to output the first start signal STV1 and the second start signal STV2 in a time-sharing manner, the problem that the first cascade gate scan circuit 100 and the second cascade gate scan circuit 200 of the gate scan circuit 10 fail to perform cascade transmission due to the fact that the first start signal STV1 or the second start signal STV2 cannot maintain a potential after touch scanning does not occur.
Referring to fig. 2, fig. 2 is a block diagram illustrating an integrated circuit architecture for gate scan touch scan according to an embodiment of the present invention. Compared to the schematic diagram shown in fig. 1, fig. 2 shows the circuit configuration and the signal arrangement inside the first cascaded gate scanning circuit 100 and the second cascaded gate scanning circuit 200, wherein the first cascaded gate scanning circuit 100 is configured to receive the first constant voltage low potential VSSG, the second constant voltage low potential VSSQ, and a plurality of clock signals CLK 1-CLK (N/2), and the first gate scanning unit of the first stage is configured to switch in the first start signal STV1, the first constant voltage low potential VSSG, the second constant voltage low potential VSSQ, the pull-down signal, and the clock signal CLK1, and is configured to output the first scanning signal G1 of the first stage.
The first gate scan unit Goa1N of the last stage of the first cascaded scan circuit 100 is configured to output a first scan signal G (N/2) and a first touch start signal TP1 of the last stage, and the first touch module 300 performs a first touch scan after receiving the first touch start signal TP 1. At this time, the first touch scan is performed when the gate scan circuit 10 has not completely performed the gate scan of one frame of image, so that the gate scan circuit 10 completes the effect of multiple touch scans in the gate scan of one frame of image.
Further, the second cascade gate scan circuit 200 is configured to receive the first constant voltage low potential VSSG, the second constant voltage low potential VSSQ, and a plurality of clock signals CLK1 to CLK (N/2), wherein the second gate scan cell of the first stage is configured to switch in the second start signal STV2, the first constant voltage low potential VSSG, the second constant voltage low potential VSSQ, the pull-down signal, and the clock signal CLK1, and is configured to output the second scan signal G (N/2) +1 of the first stage.
The second gate scan unit of the last stage of the second cascaded gate scan circuit 200 is configured to output a second scan signal g (n) of the last stage and a second touch start signal TP2, and the second touch module 400 performs a second touch scan after receiving the second touch start signal TP 2. At this time, the second touch scan is performed when the gate scan circuit 10 has not completely performed the gate scan of one frame of image, so that the gate scan circuit 10 completes multiple touch scans in the gate scan of one frame of image.
Through the circuit configuration disclosed by the first cascade scanning circuit 100, the second cascade scanning circuit 200, the first touch module 300, and the second touch module 400, the grid scanning touch scanning integrated circuit architecture 10 can be inserted into multiple touch scans within the grid scanning time of one frame of image, thereby doubling the number of touch scans and improving the technical effect of the refresh frequency of the touch panel. It should be noted that, as shown in fig. 2, the first start signal STV1 and the second start signal STV2 are respectively output through different lines, so that the problem of the first cascade gate scan circuit 100 and the second cascade gate scan circuit 200 of the gate scan touch scan integrated circuit architecture 10 failing to maintain the potential after the touch scan by the first start signal STV1 or the second start signal STV2 does not occur.
It should be added that, after the output signals of each stage of the first gate scan unit and each stage of the second gate scan unit in the first cascade scan circuit 100 and the second cascade scan circuit 200 are completed, the signals need to be reset, one of the methods is to connect the output signal of the gate scan cell of the next clock stage to the Reset signal port Reset of the gate scan cell of the previous clock stage in the wiring stage, for example, the 5 th stage gate scan cell in fig. 2 outputs a signal G5 and resets the 1 st stage gate scan cell, and the Reset signal port Reset of part of the first gate scan cells of the last stages in the first cascaded scan circuit 100 switches in the output signals of part of the second gate scan cells of the previous stages in the second cascaded scan circuit 200 to perform signal Reset, the output signal of the first gate scanning unit after the 4 th stage is connected to the Reset signal port Reset of the first gate scanning unit before the 4 th stage. The output signal of the second gate scan cell after the 4 th stage is connected to the Reset signal port Reset of the second gate scan cell before the 4 th stage.
Referring to fig. 3, fig. 3 is a driving timing diagram of an embodiment of a gate scan touch scan integrated circuit architecture according to the invention. The potential of each signal source is changed within a frame time, wherein the first start signal STV1 and the second start signal STV2 are outputted in a time-sharing manner and are respectively provided through different signal lines, so that the possibility that the first cascade gate scan circuit 100 and the second cascade gate scan circuit 200 of the gate scan touch scan integrated circuit architecture 10 are failed to perform level-shifting failure due to the fact that the first start signal STV1 or the second start signal STV2 cannot maintain the potential immediately after touch scan does not occur.
Referring to fig. 2 and fig. 3, it should be noted that, the gate scan touch scan integrated circuit architecture 10 uses the first cascaded scan circuit 100 and the second cascaded scan circuit 200 to alternately operate, and in the second touch period, the first output high voltage signal LC1 and the second output high voltage signal LC2 are inverted, so as to ensure that the corresponding first cascaded scan circuit 100 and the corresponding second cascaded scan circuit 200 alternately operate at different voltages, thereby increasing the service life.
Referring to fig. 4 and 5, fig. 4 and 5 are respectively block diagrams illustrating an embodiment of a gate scan touch scan integrated circuit architecture according to the present invention. The difference between the first touch module 300 and the embodiment provided in fig. 1 and fig. 2 is that when the first touch module is configured to perform touch scan, the first pull-down signal Dwn1 is further output to the first cascaded gate scan circuit 100 to keep the first scan signals of all the plurality of first gate scan units at a low voltage level, so that all the first gate scan units of the first cascaded gate scan circuit 100 are in an off state during touch sensing; the second touch module 400 is configured to output a second pull-down signal Dwn2 to the second cascaded gate scan circuit 200 to keep the second scan signals of all the plurality of second gate scan cells at a low voltage level during touch sensing, so as to ensure that all the second gate scan cells of the second cascaded gate scan circuit 200 are in an off state during touch sensing.
