US 2014/0368488 A1 · INFORMATION PROCESSING SYSTEM AND DRIVING METHOD THEREOF

Abstract

To provide an information processing system allowing eye-friendly display. The information processing system includes a liquid crystal display device (LCD) as a display unit. An image can be displayed in the LCD by at least two driving methods: a first driving method in which data is sequentially rewritten every frame; and a second driving method in which rewriting of data is stopped after data is rewritten once or more times at the same refresh rate as the first driving method. After the display by the second driving method, each pixel is inversely driven plural times by a signal with an amplitude greater than or equal to 80% and less than or equal to 100% of the maximum amplitude of the data signal, whereby degradation of a liquid crystal material is repaired.

Dependent claims

A method for driving a display device including a pixel comprising a transistor, the method including steps of:

in a first frame, applying a first voltage to a first terminal of the transistor;
in a second frame, applying a second voltage to the first terminal of the transistor;
in a third frame, applying a third voltage to the first terminal of the transistor;
and
in a fourth frame, turning off the transistor,
wherein the first voltage and the third voltage are different in potential from each other,
wherein the second voltage is greater than or equal to 80% and less than or equal to 100% of the first voltage, and
wherein the first to the fourth frames are sequential.
