Patent ID: 7221343

Claim:
An image display apparatus comprising: a plurality of pixels disposed on a substrate, and a plurality of signal lines disposed on said substrate for inputting an analog display voltage signal into each of said plurality of pixels, wherein: each of said plurality of pixels is provided with a light emitting element with light intensity thereof varying with a current therethrough, and a pixel circuit for driving said light emitting element, and said pixel circuit is provided with: switch means for switching between two states of supply and cutoff of a current to said light emitting element, preset means for presetting said switch means at one of said two states independently of said analog display voltage signal, and reset means for reversing said one of said two states of said switch means based upon said analog display voltage signal wherein said reset means is provided with storage means for storing said analog display voltage signal, is supplied with a triangular waveform voltage signal, is provided with at least one thin film transistor, supplies a voltage difference between said analog display voltage signal stored in said storage means and said triangular waveform voltage signal to a gate electrode of said at least one thin film transistor, and determines timing for resetting said switch means by comparing said voltage difference with a threshold voltage of said at least one thin film transistor.
