Problems solved by technology

[0003] The above driving architecture requires a complex shift circuit to drive the touch electrodes one by one. The shift circuit is usually designed independently of the driver IC and is usually installed on the display panel. Its structure is relatively complicated and requires a large panel space. The touch electrodes can only be scanned in a specific order, the scanning order of the touch electrodes is difficult to change, and the control flexibility is poor

Abstract

The invention discloses a drive unit, a drive method, a drive circuit and a display panel. The drive unit is used for providing a signal for a touch electrode of an array substrate and comprises a first control signal input end, a second control signal input end, a gating signal input end, a touch drive module, a display drive module and a signal output end; the touch drive module is used for outputting a touch signal to the signal output end under the control of a signal input by the first control signal input end, a signal input by the second control signal input end and a signal input by the gating signal input end; the display drive module is used for outputting a common voltage signal to the signal output end under the control of the signal input by the gating signal input end. The drive unit can simplify the drive circuit of the touch electrode, panel space occupied by the drive circuit is reduced, and control flexibility of touch scanning is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a driving unit, a driving method, a driving circuit and a display panel. Background technique [0002] Touch screens are divided into self-capacitive touch screens and mutual-capacity touch screens according to their touch control principles. Existing mutual capacitive touch screens usually use touch reference electrodes and touch sensing electrodes to form mutual capacitance, and detect touch points by measuring the change of charge in the mutual capacitance during touch. In the driving architecture of the above-mentioned mutual capacitance touch display screen, it is necessary to design a shift circuit to sequentially provide touch detection signals to the touch reference electrodes. The shifting circuit may include multi-level shifting units, each level of shifting unit corresponds to a touch reference electrode, and each level of shifting unit respectively shifts ...
