Problems solved by technology

[0003] At present, for using In-cell technology to embed touch devices and light control devices into display panels, touch devices, light control devices and display devices are simultaneously When working, there is a parasitic capacitance between the electrodes in the touch device and the electrodes in the light control device, which causes the signals on the two electrodes to interfere with each other, and the electrodes in the touch device and the electrodes in the light control device are all connected to the electrodes in the display device. The electric fields used to drive liquid crystals crosstalk each other, thereby reducing the reliability of the touch devices, light control devices and display devices in the display panel.

Abstract

The invention provides a display panel, a driving method thereof and a display device. The display panel comprises a substrate, a light control device, a display device and a touch control device, andthe light control device, the display device and the touch control device are arranged on the substrate; the light control device, the display device and the touch control device work in a first timeperiod, a second time period and a third time period respectively, and any two of the first time period, the second time period and the third time period have no intersection. According to the scheme, parasitic capacitance between the electrodes in the touch control device and the electrodes in the light control device is reduced, so that mutual interference of signals on the two electrodes is reduced, and the phenomenon that the electrodes in the touch control device, the electrodes in the light control device and an electric field, used for driving liquid crystal, in the display device interfere with one another is weakened; and the working reliability of the touch control device, the light control device and the display device in the display panel is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to the manufacture of display devices, in particular to a display panel, a driving method thereof, and a display device. Background technique [0002] As consumers demand both touch control and light control functions, it is inevitable to develop the technology of integrating touch control devices and light control devices into display devices. [0003] At present, for using In-cell technology to embed the touch device and the light control device into the display panel, when the touch device, the light control device and the display device work at the same time, the electrodes in the touch device and the electrodes in the light control device There is a parasitic capacitance between the electrodes, which causes the signals on the two electrodes to interfere with each other, and the electrodes in the touch control device and the electrodes in the light control device all cr...
