Abstract
Official abstract text for this publication.
A pulse generator that is capable of improving (e.g., increasing) the rising and falling speeds of its pulses. The pulse generator includes a third switch and a first diode serially coupled between a first power source and a data line; a fourth switch and a second diode serially coupled between the data line and a second power source configured to have a voltage lower than that of the first power source; a pulse controller for increasing a voltage of the data line to a voltage higher than that of the first power source or for reducing the voltage of the data line to a voltage lower than that of the second power source; and a first capacitor coupled between the pulse controller and the data line.
First claim
Opening claim text (preview).
What is claimed is: 1. An organic light emitting display, comprising: a first pulse generator for outputting a high voltage of a first power source or a low voltage of a second power source to a first data line; a second pulse generator separate from the first pulse generator for outputting the low voltage of the second power source to a second data line when the high voltage of the first power source is output to the first data line from the first pulse generator and for output…
