Abstract

The invention provides an OLED device and an array substrate. The embodiments of the invention provide an OLED device which is configured such as that: two transparent anode layers are arranged, and a metal layer is arranged between the two transparent anode layers so as to reduce resistance of the transparent anodes in a horizontal direction. The OLED device increases horizontal conductivity of the transparent anodes, addresses the problem of uneven light emission caused by large horizontal resistance of the transparent anodes for OLED devices, and increases quality of image displaying.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to an OLED (organic light emitting diode) device and an array substrate. 【Background technique】 [0002] At present, in the working process of a large-area OLED (Organic Light Emitting Diode) display panel, uneven light emission often occurs. There are many reasons for this phenomenon. The main reasons are uneven distribution of vertical resistance and excessive horizontal resistance. Among them, the vertical resistance is mainly determined by the energy level structure of the device, the carrier mobility and the thickness of each film layer; the horizontal resistance is determined by the conductivity of the transparent electrode. [0003] At present, it is difficult to make a transparent electrode with low level resistance, so the horizontal resistance (that is, the resistance in the horizontal direction) of the transparent anode is relatively high at present. When the OLED is ...
