SENSING CIRCUIT AND ORGANIC LIGHT EMITTING DIODE DISPLAY DEVICE HAVING THE SAME

摘要

A sensing circuit capable of simplifying a configuration of a data driver by reducing a size of a sensing circuit provided at each data driver, and an organic light emitting diode (OLED) display device having the same are provided. The sensing circuit includes N sampling and holding circuits, a scaler and an analog-digital converter.

主权项

1. A sensing circuit comprising:
N sampling and holding circuits to output a plurality of sampling voltages from a plurality of sensing voltages sequentially input through a plurality of reference lines, where N is a positive integer; a scaler commonly connected to the N sampling circuits to output a plurality of scaling voltages from the plurality of sampling voltages; and an analog-digital converter to perform an analog-digital conversion for the plurality of scaling voltages so as to output a plurality of sensing data.
