Title:
ORGANIC LIGHT-EMITTING DIODE DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2016/033884
Kind Code:
A1
Abstract:
Provided are an organic light-emitting diode (OLED) display device and manufacturing method thereof. The display device comprises an array substrate (201) comprising a plurality of pixel open regions, and light-emitting devices located on the array substrate and in each pixel open region; the light-emitting devices comprise hole transport layers (204), light-emitting layers (206) and electron transport layers (208); vertical projections of the light-emitting layers on the array substrate limit the pixel open regions; the hole transport layers and the electron transport layers are respectively located at two sides of the light-emitting layers or at the same side of the light-emitting layers; and the vertical projections of both the hole transport layers and the electron transport layers on the array substrate partially cover the pixel open regions, and do not overlap with each other. The display device and the manufacturing method thereof reduce the number of film layers passed through by light rays transmitted to the external portion of the light-emitting devices, reduce the loss of light rays caused by the absorption and scattering of the film layers, and increase an external quantum efficiency of the light-emitting devices and a light-emitting efficiency of the display device.
