OLED DEVICE FOR BOTH-SIDES DISPLAY

摘要

The present invention relates to an OLED device for a double-sided display and, more particularly, to an OLED device for a double-sided display capable of forming the double-sided display using one OLED panel by alternatively emitting light from a first OLED and a second OLED by the periodical inversion of the direction and voltage of a driving current applied to a unit OLED device. Wherein, the first OLED for a front light emission and the second OLED for a rear light emission are individually formed in one unit OLED device and the lamination orders of an electron transport layer, a light emitting layer, and a hole transport layer which are laminated on each of two OLEDs are vertically inverted.
