Title:
OLED DEVICE, OLED DISPLAY DEVICE AND PREPARATION METHOD FOR THE OLED DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/001233
Kind Code:
A1
Abstract:
Provided are an OLED device, an OLED display device and a preparation method for the OLED device. The OLED device comprises: a pixel defining layer (1) formed on a base substrate; an organic light emitting functional layer (2) located in an opening area (11) of the pixel defining layer (1); and disposed at the same layer, a first auxiliary electrode layer (3) and a second auxiliary electrode layer (4). The first auxiliary electrode layer (3) and the second auxiliary electrode layer (4) are located between the pixel defining layer (1) and the base substrate, and an electric field can be formed between the first auxiliary electrode layer and the second auxiliary electrode layer. The organic light emitting molecules of an organic light emitting material within the organic light emitting functional layer (2) are in an oriented arrangement under the action of the electric field. The OLED device can enhance carrier transport rate and match electron transport rate, thereby improving the luminous efficiency and lifetime of the OLED device. Drawing_references_to_be_translated
