Abstract

The invention discloses an evaporation crucible, and aims at solving the problems that the evaporation efficiency is low and the evaporation crucible is burnt out due to an unstable sublimation rate when a molten metal material is evaporated in an existing vacuum thermal evaporation technology. The evaporation crucible comprises a crucible body; and a latticed bump structure is formed on the inner surface of the bottom part of the crucible body.

Description

technical field [0001] The invention relates to the field of organic electroluminescence display technology manufacturing process, in particular to an evaporation crucible. Background technique [0002] Flat panel display devices have many advantages such as thin body, power saving, and no radiation, and have been widely used. Existing flat panel display devices mainly include liquid crystal display devices (Liquid Crystal Display, LCD) and organic electroluminescent display devices (Organic Light Emitting Display, OLED). Among them, compared with LCD, OLED display devices not only have excellent display performance, but also have all-solid-state, white light emission, simple structure, ultra-thin, fast response, wide viewing angle, room temperature operation, low power consumption and easy realization of flexible display and 3D display and other advantages have been favored by major display manufacturers. [0003] OLED display devices usually consist of an anode, a cathod...
