摘要： A touch panel and a manufacturing method thereof, and a touch display device are provided. The touch panel includes a first substrate (10) and a second substrate (20) disposed opposite to each other, and the first substrate (10) and the second substrate (20) have an interval therebetween. The first substrate (10) includes a first base substrate (100) and a force touch electrode layer (104) disposed on the first base substrate (100), the force touch electrode layer (104) includes a plurality of independent force touch electrodes (1040). The second substrate (20) includes a second base substrate (200) and a capacitance reference layer (201) disposed on the second base substrate (200). In the touch panel and touch display device, the structure and technological process of force touch are greatly simplified, the cost is greatly reduced, and the force touch technology is easier to apply and promote.

摘要： A scanning circuit, a driver circuit, a touch display panel, a receiving switching circuit and a driving method are disclosed. The scanning circuit (10) includes a function switching circuit (100) and a plurality of shift register units (200) that are cascaded. Each of the plurality of shift register units (200) that are cascaded includes a control terminal (CTRL1) and a shift scanning output terminal (OUT1), and is configured to output a first output signal at the shift scanning output terminal (OUT1) in response to a control signal received by the control terminal (CTRL1); the function switching circuit (100) includes a mode switching input terminal (SW), a control signal output terminal (CTRL2) and a mode scanning output terminal (OUT2), and the control signal output terminal (CTRL2) and the mode scanning output terminal (OUT2) are respectively connected to the control terminals (CTRL1) and the shift scanning output terminals (OUT1) of the plurality of shift register units (200) that are cascaded. The function switching circuit (100) is configured to output the control signal to the control terminals (CTRL1) of the plurality of shift register units (200) that are cascaded at the control signal output terminal (CTRL2) or to output a second output signal to the shift scanning output terminals (OUT1) of the plurality of shift register units (200) that are cascaded at the mode scanning output terminal (OUT2) in response to a mode switching input signal received at the mode switching input terminal (SW). The scanning circuit can realize fingerprint identification and touch control functions at any position in a display screen without greatly increasing the number of channels for driving the fingerprint identification units.
