and is triggered by the touch scan signal to communicate the corresponding pad 210 and the touch module 120, and performs the transmission of the touch signal with the touch module 120 within the touch time T2 of each frame.
In the embodiment, the touch module 120 is disposed in the Display module 110, and the touch Display panel 1 can be an OLED (Organic Light-Emitting Diode) touch Display panel 1 or an LCD (Liquid Crystal Display) touch Display panel 1.
When the touch display panel 1 is an OLED touch display panel 1, the display module 110 includes a substrate and an OLED light emitting device disposed on the substrate, the OLED light emitting device includes an OLED display module, an organic light emitting function layer and an OLED anode, the touch module 120 includes a touch electrode layer and a correspondingly connected touch driving circuit, and the touch electrode layer is disposed on the OLED light emitting device in an insulating and isolating manner.
When the touch display panel 1 is an LCD touch display panel 1, the display module 110 includes a first substrate, a second substrate and a liquid crystal layer disposed between the first substrate and the second substrate, the touch module 120 includes a touch electrode layer disposed in the liquid crystal layer and a touch driving circuit correspondingly connected to the touch electrode layer.
The touch electrode layer comprises touch driving electrodes and touch sensing electrodes which are arranged in an array, the touch driving circuit generates a touch driving signal according to a received touch signal and transmits the touch driving signal to the touch driving electrodes, the sensing signal sensed by the touch sensing electrodes is transmitted back to the touch driving circuit, and the touch driving circuit converts the sensing signal into a corresponding electric signal or a digital signal and transmits the electric signal or the digital signal back to a corresponding driving module through the time-sharing output circuit 220 to complete touch work.
Meanwhile, the display module 110 includes corresponding data lines, scan lines and pixel units, and the display module 110 controls the pixel units to illuminate and display correspondingly according to the received display signal, or includes corresponding power signal lines, and drives the OLED light-emitting elements to illuminate and display according to the received current signal.
The corresponding number of time-sharing output circuits 220 is set according to touch requirements, a plurality of pads 210 in the plurality of pads 210 are used for connecting the time-sharing output circuits 220 and multiplexing transmission of display signals and touch signals, the remaining pads 210 can be used only for transmitting the display signals, the touch scanning signals and the display scanning signals, each pad 210 includes a plurality of channel electrodes, wherein the plurality of channel electrodes in the plurality of pads 210 are correspondingly connected with the plurality of time-sharing output circuits 220, the plurality of channel electrodes are used for transmitting the display signals and the touch signals, and simultaneously, the display scanning signals and the touch scanning signals are output to the time-sharing output circuits 220 through the corresponding channel electrodes corresponding to one or more of the pads 210.
The display signal, the touch signal, the display scanning signal and the touch scanning signal can be input and output by the same driving chip or different driving chips, when the same driving chip outputs the signals, different types of output ports of the same driving chip are correspondingly connected with the channel electrodes of the pad 210 through the flip-chip film 240, and when the same driving chip outputs the signals, different types of output ports of different driving chips are correspondingly connected with the channel electrodes of the pad 210 through the flip-chip film 24.
The touch display panel 1 works in a display mode and a touch mode in each frame, and in the display mode, the display scanning signal output by the driving chip controls each time-sharing output circuit 220 to switch to the first path to communicate the first end and the second end of the display scanning signal, that is, the corresponding pad 210 and the display module 110, and meanwhile, the display signal is input and output through the channel electrode connected with the corresponding time-sharing output circuit 220 and the pad 210, so that the transmission of the display signal is completed, and the display module 110 is driven to light up the display.
In the touch mode, the touch scan signal output by the driver chip controls each time-sharing output circuit 220 to switch to the second channel, and connects the first end and the third end of the driver chip, that is, connects the multiplexing pad 210 and the touch module 120, and meanwhile, the touch signal is input and output through the corresponding channel electrode of the multiplexing pad 210, so as to complete the transmission of the touch signal and drive the touch module 120 to complete the touch operation.
For example, when the number of the touch signals is 3, only 3 of the time-sharing output circuits 220 may be provided, the 3 touch signals and the 3 display signals multiplex the same or different channel electrodes in the corresponding pads 210, and the channel electrodes of the remaining pads 210 are used for transmitting the display signals, the touch scan signals, and the display scan signals.
Because the types of the touch signal and the display signal may be different, or the operating modes of the touch module 120 and the display module 110 are different, when the time-sharing output circuit 220 operates in one of the modes, the channel of the other mode may be kept on or off, for example, when operating in the display mode, the channel of the touch mode may be turned on or off, the time-sharing output circuit 220 only needs to satisfy that when operating in one of the modes, the channel for transmitting the corresponding signal is kept on, and the on-off state corresponding to the other channel is not limited.

The time-sharing output circuit 220 may adopt a corresponding switch structure, or a single-input multi-output circuit structure, and may be correspondingly configured according to input and output requirements of the touch signal and the display signal, which is not specifically limited herein.
It can be understood that, since the touch module 120 and the display module 110 reuse the same set of pads 210 of the touch display panel 1, in order to satisfy the display requirement, the number of pads 210 and the internal channel electrodes are correspondingly set and selected according to the number of display signals of the display module 110, wherein the number of touch signals of the touch module 120 is smaller than the number of display signals of the display module 110.
For example, when the touch display panel 1 is an OLD touch display panel 1 and the touch display panel 1 is connected to a source driver chip and a gate driver chip through the pad 210 and the corresponding flip-chip film 240 respectively, the display signal transmitted through the corresponding type of flip-chip film 240 may only include a gray scale voltage signal output by the source driver chip or only include a row scan signal output by the gate driver circuit, that is, the multiplexing pad 210 is used for transmitting the gray scale voltage signal and the touch signal or is used for transmitting the row scan signal and the touch signal.
Or, when the touch display panel 1 is an OLD touch display panel 1 and the touch display panel 1 is a GOA driving architecture, the pad 210 and the corresponding flip-chip 240 are connected to a driving chip, the display signal output by the driving chip includes a gate driving signal for driving the GOA driving circuit 230 to operate and a gray scale voltage signal output to the touch display panel 1, and at this time, the signal transmitted by the pad 210 includes the gate driving signal, the gray scale voltage signal and the touch signal.
Or when the touch display panel 1 is an OLED touch display panel 1, at this time, the pads 210 and the corresponding flip-chip films 240 are connected to the driving chip, and the transmitted display signals may include current signals, that is, the multiplexing pads 210 are used for transmitting the current signals and the touch signals.
Therefore, according to different driving architectures of the touch display panel 1, the type of the signal transmitted by the pad 210 may be set correspondingly, and the specific type is not limited.
In the embodiment of the application, the touch display panel 1 is connected with the pad 210 for transmitting the display signal and the touch signal by adopting the time-sharing output circuit 220, the time-sharing output circuit 220 is communicated with the display module 110 and the pad 210 to transmit the display signal within the display time T1, so as to drive the display module 110 to light up and display, the time-sharing output circuit 220 is communicated with the touch module 120 and the pad 210 to transmit the touch signal within the touch time T2, thereby realizing the touch work of the panel, the bonding process times are reduced by multiplexing the pad 210, the yield of the touch display panel 1 is improved, and meanwhile, the narrow edge of the touch display panel 1 is realized.
