Abstract

The embodiment of the invention discloses a driving circuit and a driving method of a display panel, and the driving circuit of the display panel comprises a second device which is used for outputting a noise signal when a first scanning signal is accessed to a first device and a second scanning signal is not accessed to the second device; the second device is also used for outputting an integrated signal when the first scanning signal is accessed to the first device and the second scanning signal is accessed to the second device; a signal acquisition module which is used for acquiring the noise signal and the integrated signal; and a control module which is used for controlling the display panel to make a corresponding response according to the difference value between the voltage of the integrated signal and the voltage of the noise signal. The display panel has the touch control function and the light control function at the same time, noise signals and integrated signals are collected through the signal collection module, accurate light control induction signals or accurate voltage of the touch control induction signals can be obtained, and therefore the problem that the touch control device and the light control device interfere with each other when working at the same time can be effectively solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a driving circuit and a driving method of a display panel. Background technique [0002] With the development of display technology, in order to reduce costs, integrating various sensors into display panels has become a mainstream trend in the industry, such as integrating touch sensors and light sensors into display panels. [0003] However, the existing display panels generally only integrate touch sensors or only light sensors, which cannot satisfy the touch and light control functions required by customers at the same time. Contents of the invention [0004] The embodiment of the present application provides a driving circuit and a driving method of a display panel, which can solve the problem that the existing display panels generally only integrate touch sensors or only light sensors, which cannot meet the needs of touch and touch sensors required by customers ...
