Embodiment Construction

[0052] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe in detail the embodiments of the present invention in conjunction with the accompanying drawings.

[0053] The transistors used in all the embodiments of the present invention can be thin film transistors or field effect transistors or other devices with the same characteristics, and the transistors used in the embodiments of the present invention are mainly switching transistors according to their functions in circuits. Since the source and drain of the switching transistor used here are symmetrical, the source and drain are interchangeable. In the embodiments of the present invention, the source is called the first pole, and the drain is called the second pole. According to the form in the accompanying drawings, it is stipulated that the middle terminal of the transistor is the gate, the signal input terminal is the source terminal, and...

Abstract

The invention discloses a shift register unit, a driving method, a circuit, a display panel and a device, belonging to the technical field of display. The shift register unit includes a signal transmission circuit connected to an output terminal of the shift circuit, a touch signal line, a common electrode line and a touch electrode. The signal transmission circuit can output a touch modulation signal from the touch signal line to a touch electrode connected thereto under the control of a driving signal output from the shift circuit, and output a touch signal fed back from the touch electrodeto the touch signal line. As the touch signal line may be connected to the touch IC and a plurality of shift register unit, respectively, each shift register unit may be connected to one touch electrode. Therefore, touch detection of each touch electrode included in the touch display panel can be realized by setting only a small number of touch signal lines, so that the number of traces in the lead area around the touch display panel is small.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register unit, a driving method, a circuit, a display panel and a device. Background technique [0002] An in-cell touch display (full in cell, FIC) panel, as a product integrating touch and display driver integration (TTDI), is widely used in display devices. The FIC panel may generally include: a plurality of touch electrodes arranged in an array, and touch detection signal lines connected to the plurality of touch electrodes in one-to-one correspondence. [0003] In the related art, the FIC display panel further includes a plurality of data lines, and each touch detection signal line in the plurality of touch detection signal lines is parallel to the data line. And each touch detection signal line is connected to a touch integrated circuit (integrated circuit, IC) located on one side of the FIC panel, and the touch detection signal line is used to connect the touch I...
