Driving method and circuit of display module and display device

Abstract

The invention provides a driving method and circuit of a display module and a display device, and belongs to the technical field of display. The driving method comprises the following steps: for an a-th sub-pixel of each group of sub-pixels, in a transition time period between display time periods of two adjacent a-th sub-pixels, inputting a transition data signal to a data line corresponding to the a-th sub-pixel, and inputting a closing signal to a gate scanning signal line corresponding to the two adjacent a-th sub-pixels, the potential of the transition data signal is smaller than a first potential and larger than a second potential, the first potential is the maximum value of the data signals of the two adjacent ath sub-pixels in the display time period, and the second potential is the minimum value of the data signals of the two adjacent ath sub-pixels in the display time period. According to the technical scheme, the display noise can be reduced.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a driving method, a circuit and a display device of a display module. Background technique [0002] Display products are usually equipped with a capacitive active pen. However, due to the interference of display noise, the signal of the active pen is easily disturbed or even submerged by the noise signal, resulting in poor effect of the active pen, and it is difficult to ensure a good user experience effect. Some manufacturers use a higher active pen drive voltage to enhance the active pen signal, but this approach cannot fundamentally solve the problem, and the higher the voltage, the greater the power consumption, which affects the battery life of the active pen. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a driving method, circuit and display device for a display module, which can reduce display n...
