Abstract

The invention relates to a double-panel device comprising two panels driven simultaneously. The double-panel device includes a first panel, a second panel and a data driver. The first panel has a plurality of pixels formed in intersection regions of the data lines and the first scan lines. The second panel has a plurality of second pixels formed in intersection regions of the data lines and the second scan lines. The data driver provides compensating precharge current to one or more data lines. The double-panel device uses two panels as a main display device and a sub-display device, and thus reduces the unit cost of the double-panel device.

Description

Technical field [0001] The invention relates to a double panel device. More specifically, the present invention relates to a double panel device including two panels driven at the same time and a driving method thereof. Background technique [0002] The double panel device uses two panels as the main display device and the sub display device. For example, the dual panel device is a mobile phone. [0003] The dual panel device uses a liquid crystal display (hereinafter, referred to as "LCD") as the main display device, and uses an organic electroluminescence panel as the sub display device. Therefore, the dual panel device should have a first integrated circuit chip to drive the LCD and a second integrated circuit chip to drive the organic electroluminescent panel. [0004] In addition, since the price of the LCD is higher than that of the organic electroluminescence panel, the price of the dual panel device is increased. Summary of the invention [0005] The feature of the prese...
