Problems solved by technology

However, in order to prevent the organic layer from covering the position of the exposed area 16 of the auxiliary electrode, a precise metal mask 17 needs to be provided. This metal mask 17 is not easy to manufacture, the cost is high, and alignment is not easy. The cover is prone to bending problems

Abstract

The invention provides organic light-emitting diodes (LEDs) and an organic LED displayer composed of the same. Each organic LED comprises a substrate which comprises a pixel electrode area and an auxiliary electrode area, and an insulating layer formed between the pixel electrode area and the auxiliary electrode area, wherein the pixel electrode area comprises a first electrode formed on the substrate, an organic layer formed on the first electrode and a second electrode formed on the organic layer, and the auxiliary electrode layer comprises an auxiliary electrode formed on the substrate and a shielding structure formed on the auxiliary electrode or on the insulating layer. The shielding structure shields partial auxiliary electrode, and the second electrode is in electric connection with the auxiliary electrode.

Description

technical field [0001] The present invention relates to an organic light emitting diode, and in particular to an organic light emitting diode which avoids voltage drop and an organic light emitting diode display composed of the same. Background technique [0002] Organic light-emitting diodes (organic light-emitting diodes) are widely used in flat-panel displays due to their advantages of high brightness, lightness, thinness, no need for backlight sources, and low power consumption. [0003] See Figure 1A , which shows a top view of an existing organic light emitting diode 10, which includes a display area 12a and a peripheral area 12b located on the periphery of the display area 12a, and an auxiliary electrode contact hole (contact hole) 14 is located in the peripheral area 12b for connecting with the display area The upper electrode (not shown in the figure) of 12a is electrically connected. The power is input from the auxiliary electrode via hole 14 in the peripheral ar...
