Patent ID: 7965263

Claim:
A display device, comprising: a light emitting element; and a driving transistor coupled for supplying an emission intensity defining driving current to the light emitting element at time intervals when the light emitting element is to emit light of corresponding intensity, the driving transistor having a first gate, a first source, and a first drain; a gate controlling circuit coupled to the first gate, the gate controlling circuit having a first switch coupled to selectively apply a supplied data voltage to the first gate, and having a second switch coupled to selectively apply a supplied reverse biasing voltage signal to the first gate; a reverse bias signal generator coupled to the second switch and operative to supply a time varying voltage signal forming at least part of the supplied reverse biasing voltage signal, where the time varying voltage signal includes a succession of plural voltage pulses each having at least one voltage level that causes the driving transistor to become reverse biased when the second switch is closed and when the at least one, reverse-biasing voltage level is then being supplied by the reverse bias signal generator as part of the reverse biasing voltage signal.
