LIGHT-EMITTING PIXEL AND APPARATUS FOR DRIVING THE SAME

摘要

A light emitting pixel and an apparatus for driving the same are provided to obtain constant luminance after elapsing some times by supplying constantly currents to an OLED irrespective of characteristic reduction of light emitting pixels. A light emitting pixel includes a first OLED(Organic Light Emitting Diode)(110) and a capacitor(130). The capacitor supplies a current, which is generated from charges corresponding to a difference between a first voltage supplied to a first electrode thereof and a second voltage supplies to a second electrode thereof, to the first OLED. The light emitting pixel further includes a second OLED(140) which supplies the first voltage to the first electrode. The light emitting pixel further includes a voltage supply element for supplying the first voltage to the first electrode in response to the second voltage.
