Abstract

The invention provides a crucible device and an evaporation device. The crucible device is used to evaporate metal aluminum materials. The crucible device comprises an outer layer crucible body and aninner layer crucible body; the outer layer crucible body is provided with an outer layer cavity whose surface is covered with a heat reflective coating; and the inner layer crucible body is providedwith a body part nested in the outer layer cavity of the outer layer crucible body. On the one hand, by arranging the heat reflective coating on the inner wall of the outer layer crucible body, the evaporation material in the crucible device can maintain a stable vaporization rate, and the evaporation rate is effectively increased; and on the other hand, grooves are formed in the upper part of theinner layer crucible body, and the grooves are provided with overflow holes which can be used to channel overflow liquid to the outer layer crucible body, so that the risk of liquid emerging from theupper surface of the crucible device and damaging the crucible device is reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a crucible device and an evaporation device. Background technique [0002] OLED (Organic Light-Emitting Diode, organic light-emitting diode, referred to as OLED) display is thin, light, wide viewing angle, active light emission, continuously adjustable light color, low cost, fast response, low energy consumption, and low driving voltage. Low temperature, wide operating temperature range, simple production process, high luminous efficiency and flexible display, etc., have been listed as a promising next-generation display technology. [0003] At present, the main method of making OLED devices is heating evaporation coating, mainly under certain vacuum conditions, using a heating container to heat the evaporation material, so that the evaporation material is melted (or sublimated) into a vapor composed of atoms, molecules or atomic groups, and then It is deposited on a ...
