Embodiment Construction

[0029] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0030] see Figure 4 , is a schematic cross-sectional structure diagram of the first embodiment of the crucible for preventing OLED material cracking according to the present invention. The crucible for preventing cracking of OLED materials includes a crucible body 1 for containing OLED materials 3 , and a cover 2 covering the opening end of the crucible body 1 .

[0031] The bottom of the crucible body 1 has a lifting structure 11, through which the height of the lowest liquid level of the OLED material 3 in the crucible is raised. The height H from the top surface of the lifting structure 11 to the bottom surface of the crucible body 1 is greater than or equal to the minimum liquid level height allowed for normal evaporation of the OLED mat...

Abstract

The invention provides a crucible for preventing cracking of OLED materials, comprising a crucible body (1) for containing OLED materials (3), and a cover (2) covering the opening end of the crucible body (1); the crucible There is a lifting structure (11) at the bottom of the body (1), through which the height of the lowest liquid level of the OLED material (3) in the crucible is raised through the lifting structure (11), so that the OLED material (3) is completely Steam out. The invention can solve the problem that the OLED material in the crucible is easily cracked and the material is wasted in the vapor deposition process, so that the vapor deposition process runs stably and ensures the quality of the OLED display device.

Description

technical field [0001] The invention relates to the field of manufacturing processes of OLED display devices, in particular to a crucible for preventing cracking of OLED materials. 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, self-luminous, 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, known as "dream display", unanimously recognized as the mainstream technology of next-generation display, and has b...
