LIGHT EMITTING DISPLAY DEVICE AND THE METHOD FOR DRIVING IT

摘要

An organic electro luminescence display and a driving method thereof are provided to improve brightness nonuniformity by measuring a threshold voltage of a thin film transistor for driving unit pixels of the organic electro luminescence display and correcting the threshold voltage. A light emitting element(320) emits light in accordance with a data voltage. A first transistor(331) drives the light emitting element. A second transistor(332) drives the first transistor in accordance with a first scan signal. A third transistor(333) is connected to one terminal of the first transistor and is driven in accordance with a second scan pulse input after the first scan signal. The data voltage is stored in a storage element(340).
