Abstract

The invention discloses an OLED (Organic Light Emitting Diode) mask and an application method thereof. The mask is transversely provided with odd number lines of groove groups consisting of longitudinally arrayed grooves; the distance between the groove groups on the mask is the width of two grooves; and the distance between the groove groups with a minimum transverse edge distance of the mask is the width of one groove. The method comprises the following steps of: firstly, evaporating a green evaporation material; aligning a substrate and the mask with a conventional method and then evaporating after the aligning is finished; in the same evaporating cavity, respectively placing three different evaporation materials in different evaporating units so as to be convenient for time-sharing work; after green evaporating is finished, moving the mask to a red aligning position through an aligning servo motor by utilizing a determined position relation to evaporate a red evaporation material, wherein at the moment, baffle plates of the green evaporating unit and a glue evaporating unit are in a closed state; and realizing the evaporating of a blue evaporation material in the same way. The invention greatly simplifies the equipment structure and reduces the quantity of the masks, and meanwhile, the production efficiency is greatly improved.

Description

[0001] Technical field: [0002] The invention relates to an evaporation process of an organic light-emitting device, and mainly relates to a mask used in the evaporation process of an OLED device and an application method thereof. Background technique: [0003] Organic Light Emitting Diode (OLED) has many advantages such as self-luminescence, fast response time, wide viewing angle, low cost, simple manufacturing process, good resolution and high brightness, and is considered to be an emerging application technology of the next generation of flat panel displays. In OLED technology, mask plate technology in vacuum evaporation is a very important and key technology, and the level of this technology directly affects the quality and manufacturing cost of OLED products. The usual three colors of red, green and blue are different due to different evaporation materials and different attachment positions of different materials on the substrate. The evaporation of red, green and blue...
