Abstract

The invention relates to the technical field of evaporation and discloses a crucible. The crucible comprises a crucible body, the crucible body is provided with a cavity, the first end of the crucible body is sealed, and an opening communicated with the cavity is formed in the second end of the crucible body. The crucible further comprises at least one heat conduction part, each heat conduction part is located in the cavity, and the heat conduction parts divide the cavity into multiple containing areas. According to the crucible, the cavity of the crucible body is divided into the containing areas through the heat conduction parts, so that when organic materials are placed in the crucible, the organic materials are located in the containing areas, when the crucible is heated, heat will be transferred to the heat conduction parts through the inner wall of the crucible, the crucible heats the organic materials in the containing areas respectively, the organic materials can be quickly preheated, and heat is uniformly distributed. Thus, heating uniformity of the organic materials in the crucible can be improved, and the display effect of a display device is enhanced.

Description

technical field

[0001] The invention relates to the field of vapor deposition technology, in particular to a crucible. Background technique

[0002] In recent years, organic electroluminescence display (OLED), as a new type of flat panel display, has gradually received more attention. Due to its active light emission, high luminous brightness, high resolution, wide viewing angle, fast response speed, low energy consumption, and flexibility, it has become a next-generation display technology that may replace liquid crystal display.

[0003] For OLED devices, the current mass-produced mature technologies use vacuum physical vapor deposition to prepare devices, that is, put the prepared backplane in a vacuum chamber and evaporate each layer of organic material on the backplane by thermal evaporation. To form OLED devices, the evaporation process is an important technical route for the production of OLEDs, and the crucible is an essential tool for using the evaporation process....
