Problems solved by technology

However, the existence of the raised structure 106 also reduces the area that can emit light and reduces the aperture ratio (Aperture Ratio)
In addition, the process of concave-convex structure also relatively increases the process cost

Abstract

An organic light-emitting diode device used in a lighting apparatus includes: a substrate; a patterned anode layer disposed on the substrate; an organic semiconductor layer disposed to cover an upper surface and sidewalls of the patterned anode layer and the substrate, wherein a thickness of the organic semiconductor layer is greater than three times of that of the patterned anode layer; and a cathode layer disposed to cover the organic semiconductor layer. According to the invention, a step coverage of the organic semiconductor layer is increased by designing a relative thickness ration of the anode layer and the organic semiconductor layer. In this way, the edge leakage problem can be prevented and a conventional bank structure in an organic light-emitting diode device can be omitted. This improves an element yield rate and increases a light-emitting area of the organic light-emitting diode device.

Description

technical field [0001] The invention relates to an organic light emitting diode component, and in particular to an organic light emitting diode component applied to a lighting device. Background technique [0002] In the existing manufacturing process of Organic Light-Emitting Diode (OLED) components used in displays, most organic polymer layers are used to form a concave-convex structure (generally called a bank structure) to define a specific light-emitting area. To avoid leakage, short circuit and other problems. [0003] Such as figure 1 It can be seen from the schematic cross-sectional view that there is a groove 108 between two adjacent protrusion structures 106 , and the organic semiconductor layer 110 is formed in the groove 108 and disposed between the first transparent electrode 104 and the second electrode 114 . The protruding structure 106 and the organic semiconductor layer 110 separate the first transparent electrode 104 and the second electrode 114 from each...
