LIGHT EMITTING DEVICE CAPABLE OF REMOVING THE FEATURE DEVIATION INFLUENCE OF A TRANSISTOR TO CONTROL A LIGHT EMITTING ELEMENT

摘要

PURPOSE: A light emitting device is provided to obtain a clear multigrade display by reducing the change of a current flowing between two electrodes.;CONSTITUTION: A source signal line driving circuit(101) and a gate signal line driving circuit(102) are formed on a substrate. A plurality of pixels(100) includes a first pixel and a second pixel on the substrate. The plurality of pixels include a light emitting element and a transistor, respectively. Each gate of the transistors in the plurality of pixels maintains a potential corresponding to a video signal inputted from the driving circuit. A wire supplies a current to each light emitting element of the plurality of pixels.;COPYRIGHT KIPO 2013;[Reference numerals] (101) Source signal line driving circuit; (101a) Shift register; (101b) Buffer; (101c) Sampling circuit; (102) Gate signal line driving circuit; (125) Video signal line; (130) Ammeter; (131) Power source; (200) First memory; (201) Second memory; (202) Calculation circuit; (203) Third memory; (204) Signal correction circuit; (210) Correction circuit; (211) Memory medium; (AA) Video signal
