Drive method of multiple common electrodes and display device

Abstract

The invention provides a drive method of multiple common electrodes and a display device. The drive method includes the following steps: providing a plurality of common voltages which include a first common voltage and a second common voltage, wherein the first common voltage is different from the second common voltage; in a first period, selecting to set the first common voltage as a first voltage level so as to drive first common electrodes in a first pixel area in a display panel and selecting to set the second common voltage as a third voltage level so as to drive second common electrodes in a second pixel area in the display panel; and in a second period, selecting to set the first common voltage as a second voltage level so as to drive the first common electrodes and selecting to set the second common voltage as a forth voltage level so as to drive the second common electrodes.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to a driving method of multiple common electrodes and a display device. Background technique [0002] The rapid progress of the multimedia society is mostly due to the rapid progress of semiconductor devices or display devices. As far as displays are concerned, liquid crystal displays (Liquid Crystal Displays; LCD for short) with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation have gradually become the mainstream of the market. [0003] What is worth mentioning here is that the current LCD drive architecture can generally be divided into two types, one is the DC mode common voltage (DC mode common voltage) drive architecture (for example, the dot inversion drive method) , which is mostly used to drive the existing large-sized LCD panel (LCD panel), and the other is the AC mode common voltage (AC mode ...

Problems solved by technology

[0004] However, if the current large-sized LCD panel is driven by a DC-mode common voltage driving structure, although it has a better picture display effect, the overall power consumption of the LCD will also increase accordingly.

In addition, if the existing medium and small-sized liquid crystal display panels are driven by the common voltage driving structure of the AC mode, although the overall power consumption of the liquid crystal display can be reduced, the liquid crystal display may cause the entire panel to burn in a certain period of time. If the polarity is the same, it will cause flickering or residual image on the display performance, which will greatly affect the display quality of the liquid crystal display.
