Abstract

The invention provides a flat panel display device driving device and a driving method thereof. Data information pre-stored in a pre-storing data module for a fixed display picture is used, digital signals generated by a display information processing module or voltage signals generated by a voltage generation module are changed, and thus, data voltage is enhanced, pixel current is reduced, a condition in which the brightness is obviously attenuated caused by long-time lighting of a pixel of the flat panel display device is avoided, and the service life of the flat panel display device is prolonged.

Description

technical field [0001] The invention relates to the field of flat panel display technology, in particular to a driving device and a driving method for a flat panel display device. Background technique [0002] With the development of the information society, people's demand for display devices is increasing day by day. In order to meet this requirement, various flat panel display devices such as Thin Film Transistor Liquid Crystal Display (TFT-LCD), Plasma Display (PDP), and Organic Light Emitting Display (OLED) have been rapidly developed. Among flat-panel display devices, organic light-emitting display devices (OLEDs) have many advantages such as active light emission, high contrast ratio, fast response speed, and thinness, and are gradually occupying a dominant position in flat-panel displays. At present, organic light-emitting display devices (OLEDs) have been widely used in various high-performance display fields such as mobile phones, televisions, computers, and smart...
