Abstract

The present invention provides a manufacturing method of a white light OLED device. Firstly, a first OLED device and a second OLED device corresponding to each other are respectively manufactured on a first substrate and a second substrate, wherein the light emitted by the first OLED device and the The light emitted by the second OLED device is mixed into white light, and then the second OLED device is correspondingly stacked on the first OLED device to obtain a white OLED device. This manufacturing method can greatly reduce the number of existing white OLED devices. In the device manufacturing process, the complex manufacturing process caused by layer-by-layer stacking of multi-layer film materials does not need to consider the complex process problems caused by the interconnection of multi-color devices and light-color resonance, which greatly simplifies the manufacturing process.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a manufacturing method of a white light OLED device. Background technique [0002] The active matrix flat panel display has many advantages such as thin body, power saving, and no radiation, and has been widely used. Among them, organic light-emitting diode (OLED) display technology is a promising flat panel display technology, which has very excellent display performance, especially self-illumination, simple structure, ultra-thin, fast response , wide viewing angle, low power consumption, and flexible display, it is known as a "dream display", and its production equipment investment is much smaller than that of a thin film transistor-liquid crystal display (Thin Film Transistor-Liquid Crystal Display, TFT-LCD) , has been favored by major display manufacturers, and has become the main force of the third-generation display devices in the field of display technology. At present,...
