Light emitting display driver and method thereof
First Claim
1. 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.
