ORGANIC EL DISPLAY APPARATUS AND DRIVING METHOD OF THE SAME
摘要:
An organic EL display apparatus comprises a plurality of pixels, each having first and second sub pixels; an organic EL element provided for each sub pixel; a data line driver; a pixel circuit; and a gate line driver. Each pixel includes a first organic EL element arranged in a first sub pixel emitting light of the same color; and a second organic EL element arranged in a second sub pixel. The light-extraction efficiency of the second sub pixel is higher than that of the first sub pixel. At least one of a plurality of transistors applies a drive current. The reference voltage line driver supplies a reference voltage to a gate terminal of the drive transistor to perform gradation displaying on the first organic EL element at a light emitting level, and to perform gradation displaying on the second organic EL element by controlling the light emitting period.
