Abstract
A display device includes: a display panel having a plurality of sub-pixels sharing a single reference voltage line, each of the sub-pixels comprising a switching transistor, a driving transistor, a sensing transistor, a storage capacitor, and a light-emitting element; a data driver configured to supply a data voltage to the plurality of sub-pixels; a gate driver configured to supply a gate signal to the plurality of sub-pixels; a timing controller configured to control the data driver and the gate driver; and a detector configured to sense a threshold voltage and mobility of the driving transistor to detect if there is a short-circuit between a gate electrode and an output terminal of the driving transistor.
