Abstract
A single scan driver for an organic light emitting diode (OLED) display is disclosed, that can reduce the required power consumption. By connecting together both ends of each column line so that a single driver circuit can drive both ends of each column line together, the column line resistance is reduced, resulting a significant reduction in power consumption.
Claims9
A driver for driving columns of a single-scan LED panel consisting of row and column electrodes, comprising:
- a common driver circuitry;
- a first set of output leads from the driver circuitry extending to the top end of the panel to connect to the column electrodes;
- a second set of output leads from the driver circuitry extending to the bottom end of the panel to connect to the column electrodes;
- wherein both ends of each column electrode are driven at a same potential by a single driving circuit whereby the resistance along each column electrode is reduced.
