ORGANIC LIGHT EMITTING DISPLAY

摘要

PURPOSE: An organic light emitting display device is provided to efficiently prevent brightness deterioration by using an electronic ink layer which is operated with a shutter type to implement black on a screen. CONSTITUTION: A display unit(110) includes a plurality of pixels(111). A transparent window(130) is formed on the upper side of the display unit. An electronic ink layer is interposed between the display unit and the transparent window. The electronic ink layer includes a plurality of charged ink particles(120a) and a main electrode(123). The main electrode applies electric attraction to ink particles.
