Abstract
A circuit is provided to drive a controlled current from a drive transistor into one electroluminescent element of a pixel array. The circuit is operable to compensate for threshold voltage variation of the drive transistor, thereby providing improved image quality. The circuit is suitable for implementation with p-channel MOSFETs and a conventional geometry having in order: substrate, TFT layer(s), anode, electroluminescent layer(s), cathode. A driving method for this circuit is provided. A display incorporating this circuit is provided. The circuit is operable to provide an inspection function prior to fabrication of the electroluminescent layer(s). An inspection method is provided.
