Description

Driving method and display device for multiple common electrodes

technical field

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

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.

What is worth mentioning here is that the driving architecture of today's liquid crystal displays can generally be divided into two types, one is the driving architecture of DC mode common voltage (for example, the driving method of dot inversion) , mostly used to drive the existing large-sized liquid crystal display panel (LCD panel), the other is the AC mode common voltage (AC mode common voltage) driving structure (such as the line inversion driving method), mostly used to drive There are liquid crystal display panels of medium and small sizes.

However, if the current large-sized liquid crystal display panel is driven by the driving structure of the common voltage in the DC mode, although the image display effect is better, the overall power consumption of the liquid crystal display 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. In the case of the same polarity, it will cause flickering or afterimage phenomenon on the display performance, which greatly affects the display quality of the liquid crystal display.
