Abstract
Official abstract text for this publication.
An organic light emitting display device having a data line that is used for sending data voltage signals to pixels from a data driver as well as send sensor signals for detecting threshold voltage levels of driving transistors in the pixels at different times. By using the same data line to transmit the data voltage signals and the sensor signals, the number of signal lines in the organic light emitting display can be reduced. The data driver also includes switches for selectively coupling the data line to a driver unit or an analog to digital converter (ADC) unit.
First claim
Opening claim text (preview).
What is claimed is: 1. An organic light-emitting display device, comprising: a plurality of data lines; a plurality of pixels connected to each of the plurality of data lines, each pixel comprising: a first transistor configured to switch connection between a first node and a reference voltage source; a second transistor configured to switch connection between a second node and one of the plurality of data lines; an organic light emission element coupled between the second…
