ACTIVE MATRIX DISPLAY DEVICE USING ORGANIC LIGHT-EMITTING ELEMENT AND METHOD OF DRIVING ACTIVE MATRIX DISPLAY DEVICE USING ORGANIC LIGHT-EMITTING ELEMENT

摘要

An active matrix display device using an organic light emitting element and a method of driving an active matrix display device using the organic light emitting element are provided to enhance display quality by suppressing precharge at a region where the current variation is small. An active matrix display device using an organic light emitting element includes pixels(37), a driving transistor(32), a memory(761), and a voltage generator. The pixels include the organic light emitting element. The driving transistor determines current flowing in the organic light emitting element by gate voltage. The voltage generator supplies voltages to the pixels. The voltages of the voltage generator are different from one another according to data of the memory. The active matrix display device using an organic light emitting element further includes a voltage detector which detects at least one voltage among a gate voltage of the driving transistor, a drain voltage of the driving transistor, and an output voltage of the voltage generator.
