Abstract
An organic light emitting diode display is disclosed. The organic light emitting diode display includes a display panel including a plurality of pixels, a plurality of sensing units configured to integrate current information of the pixels through a plurality of sensing channels connected to sensing lines of the display panel and output a first sensing value, a reference sensing unit configured to integrate previously set reference current information and output a reference sensing value, a calculation block configured to calculate the first sensing value and the reference sensing value, remove a common noise component from the first sensing value, and output a second sensing value, and an analog-to-digital converter configured to convert the second sensing value into a digital sensing value.
