1. An OLED structure, comprising: a substrate, an over coat layer on the substrate and a micro-cavity on the over coat layer; wherein an upper surface of the over coat layer away from the substrate appears a wavy fluctuation having raised peaks and depressed troughs smoothly joined with the raised peaks, and the micro-cavity appears a wavy fluctuation in accordance with the upper surface of the over coat layer to eliminate directionality issues of luminous intensity and color for realizing wide view angle display;
wherein the micro-cavity comprises an emitting layer on the upper surface, a buffer layer on the emitting layer, an electrode layer on the buffer layer, a white light organic layer on the electrode layer, a transflective layer on the white light organic layer, each of the emitting layer, the buffer layer, the electrode layer, the white light organic layer, and the transflective layer showing a wavy fluctuation comprising raised peaks and depressed troughs substantially and respectively corresponding to the raised peaks and the depressed troughs of the upper surface of the over coat layer to eliminate the directionality issues of luminous intensity and color for realizing the wide view angle display. |
