Abstract

The invention relates to a driving method and device, a chip and electronic equipment. The method comprises the steps: determining a first gray scale corresponding to display data of an Nth display unit at the current moment and a second gray scale of display data of an Mth display unit at the adjacent previous moment; determining whether to share charges or not according to the relationship between the first gray scale and a first gray scale threshold value and the relationship between the second gray scale and a second gray scale threshold value; when it is determined that charge sharing is carried out, the data channels of the Nth display unit and the Mth display unit are controlled to carry out charge sharing; therefore, according to the method, the charges of the data channels of the Nth display unit and the Mth display unit can be averagely distributed; the initial potential of each channel is reduced or increased to be close to the common voltage; when driving is carried out, driving can be carried out through small current, so that the current consumption of the whole driving circuit is reduced, the voltage swing of a display signal during driving can be reduced, and power consumption is saved.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a driving method and device, chip and electronic equipment. Background technique [0002] With the improvement of semiconductor technology, liquid crystal displays have the advantages of low power consumption, thin and light weight, high resolution, high color saturation, and long life, so they are widely used in computers, mobile phone LCD screens and LCD TVs, etc. Electronic products closely related to life. When the display panel of a liquid crystal display displays a driving signal, the polarity of the voltage applied to both ends of the liquid crystal capacitor of each pixel is generally reversed at specific time intervals, so as to avoid permanent damage caused by polarization of the liquid crystal material. However, when the polarity of the voltage driving the display panel starts to reverse, the driving circuit consumes a large amount of current, which incr...
