Pulse generator and organic light emitting display using the same

摘要

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.

主权项

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 outputting the high voltage of the first power source to the second data line when the low voltage of the second power source is output from the first pulse generator to the first data line; pixels positioned at crossings of scan lines and data lines; a scan driver for driving the scan lines; a switching unit formed with each of the data lines to be coupled to the first pulse generator and the second pulse generator; and a data driver for controlling the switching units to be coupled to the first pulse generator or the second pulse generator in accordance with data.
