Organic light emitting diode display device and display panel thereof

摘要

An organic light emitting diode (OLED) display device and a display panel thereof are provided. The organic light emitting diode display panel comprises a first substrate, a first electrode, an organic light emitting layer, a second electrode, and a second substrate. The first electrode is disposed on the first substrate. The organic light emitting layer is disposed on the first electrode. The second electrode is disposed on the organic light emitting layer. The second substrate is located on the second electrode. The material of the second electrode comprises an alkaline earth element and silver. The second electrode comprises a first portion and a second portion, and the first portion is located between the second portion and the first substrate. The ratios of the alkaline earth element to silver in the first portion and in the second portion are different.

主权项

1. A display panel, comprising:
a first substrate; a second substrate; a first electrode disposed between the first substrate and the second substrate; an organic light emitting layer disposed between the first electrode and the second substrate; and a second electrode disposed between the organic light emitting layer and the second substrate, wherein a material of the second electrode comprises an alkaline earth element and silver; wherein the second electrode comprises a first point, a second point, and a third point, a distance between the organic light emitting layer and the first point is less than a distance between the organic light emitting layer and the second point, the distance between the organic light emitting layer and the first point is less than a distance between the organic light emitting layer and the third point, and the distance between the second point and the organic light emitting layer is different from the distance between the third point and the organic light emitting layer; and wherein a ratio of the alkaline earth element to silver of the first point is greater than a ratio of the alkaline earth element to silver of the second point, and the ratio of the alkaline earth element to silver of the first point is greater than a ratio of the alkaline earth element to silver of the third point.
