PANEL DRIVING DEVICE AND ORGANIC LIGHT EMITTING DISPLAY DEVICE HAVING THE SAME

摘要

A panel driving device includes a voltage generator and a data driver. The voltage generator generates a compensation voltage set and a gamma voltage set and selectively outputs the compensation voltage set or the gamma voltage set. The data driver outputs a reference voltage based on the compensation voltage set and outputs pixel data voltage based on the gamma voltage set.

1. An organic light emitting display device, comprising:
a display panel including a plurality of scan lines, a plurality of data lines crossing the scan lines, and a plurality of pixels; a scan driver to simultaneously provide a scan signal to the scan lines in a first period and a second period and to progressively provide the scan signal to the scan lines in a third period; a voltage generator to generate a compensation voltage set and a gamma voltage set, to output the compensation voltage set in the first period and the second period, and to output the gamma voltage set in the third period; a data driver to output a reference voltage to the data lines based on the compensation voltage set and to output a pixel data voltage to the data lines based on the gamma voltage set; and a controller to control the scan driver, the voltage generator, and the data driver.
