Problems solved by technology

Among them, the high voltage swing between the positive polarity voltage and the negative polarity voltage will increase the power consumption of the data line driver.
In addition, since two adjacent pixels in the extending direction of the scanning line have opposite polarities, the electric field generated at the junction of two adjacent pixels will cause light leakage in the liquid crystal display panel, thereby reducing the display quality.
In addition, the liquid crystal display device adopting column inversion, because the data line driver will provide the driving voltage with the same polarity in different scanning periods, so the power consumption can be reduced, but it also has the problem of light leakage of the liquid crystal display panel

Abstract

The invention discloses a display device. In the column inversion driving mode, adjacent pixels in the extending direction of the scanning line have the same polarity to reduce the power consumption of the display device. Moreover, the occurrence of light leakage at the boundary between two adjacent pixels is avoided, and the display quality of the display device can be improved.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to a display device and a driving method thereof. Background technique [0002] In order to meet the requirements of high speed, high performance, light weight and short size of modern products, all electronic components are actively developing towards miniaturization.
