ORGANIC LIGHT-EMITTING DISPLAY

摘要

An organic light-emitting display includes: a display panel including first and second pixels, each having an organic light-emitting diode; and a data driver including a first operational amplifier having a non-inverting terminal coupled to a reference voltage terminal and an inverting terminal coupled to the first pixel, and a second operational amplifier having a non-inverting terminal coupled to the reference voltage terminal and an inverting terminal coupled to the second pixel. The first pixel includes a sensing transistor, a first driving transistor, and a first switch transistor. The second pixel includes a second driving transistor and a second switch transistor.
