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...
