Abstract
A display panel driver of a light emitting display having a main panel disposed on a front surface and a sub panel disposed on a rear surface. The display panel driver includes a main scan driver sequentially applying selection signals to a plurality of scan lines in the main panel along a first direction, a sub scan driver sequentially applying selection signals to a plurality of scan lines in the sub panel along an opposite direction of the first direction, and a drive controller respectively controlling scanning directions of the main scan driver and the sub scan driver.
Claims11
A display panel driver of a light emitting display having a main panel disposed on a front surface and a sub panel disposed on a rear surface, the display panel driver comprising:
- a main scan driver sequentially applying selection signals to a plurality of scan lines in the main panel along a first direction;
- a sub scan driver sequentially applying selection signals to a plurality of scan lines in the sub panel along an opposite direction of the first direction;
- and
- a drive controller respectively controlling scanning directions of the main scan driver and the sub scan driver.
A light emitting display comprising:
- a main panel for a frontward display of the light emitting display;
- a sub panel for a rearward display of the light emitting display;
- a main scan driver sequentially applying respective selection signals to a plurality of scan lines in the main panel along a first direction;
- a sub scan driver sequentially applying respective selection signals to a plurality of scan lines in the sub panel along an opposite direction of the first direction;
- a data driver applying a data voltage to selected pixel circuits of the main panel and the sub panel, the data voltage corresponding to an image signal;
- and
- a drive controller respectively controlling scanning directions of the main scan driver and the sub scan driver.
A method for driving a light emitting display having a main panel and a sub panel respectively for frontward and rearward display of the light emitting display, the driving method comprising:
- setting scanning directions of a main scan driver and a sub scan driver opposite to each other;
- sequentially applying selection signals to a plurality of scan lines of the main panel;
- sequentially applying selection signals to a plurality of scan lines of the sub panel;
- and
- realizing displays of the main panel and the sub panel by sequentially applying a plurality of data voltage corresponding to an image signal to selected pixel circuits of the main panel and the sub panel.
