Abstract

The invention provides an evaporation device and evaporation equipment. The evaporation device comprises an evaporation container and an anti-blocking cap which are connected or separated from each other; the anti-blocking cap comprises a first outlet, a first side wall, a first blade, a first opening, a second blade, a second opening and heating wires; the first side wall surrounds the first outlet; the first blade and the second blade are positioned in the first outlet and are fixed on the first side wall; the first blade surrounds the first opening; the second blade surrounds the second opening; the second opening is smaller than the first opening; the heating wires are arranged in the first side wall, the first blade and the second blade. The anti-blocking cap avoids instant large fluctuation of evaporation gas caused by melting, boiling or collapsing of evaporation raw materials in an evaporation container, and the emitting speed of the evaporation gas on the anti-blocking cap isstable. Therefore, the evaporation device realizes a stable evaporation rate, and further realizes an excellent evaporation effect; and in addition, the anti-blocking cap prevents the evaporation gasfrom being condensed on the second outlet of the evaporation container to cause blocking.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to an evaporation device and evaporation equipment. 【Background technique】 [0002] In display technology, organic light emitting display panel (Organic Light Emitting Diode, OLED) is widely used in the industry due to its thinness, active light emission, fast response speed, wide viewing angle, rich color and high brightness, low power consumption, and high and low temperature resistance. It is recognized as the third generation display technology following the liquid crystal display panel (Liquid Crystal Display, LCD). [0003] figure 1 It is a structural schematic diagram of an evaporation device in the related art. [0004] Such as figure 1 As shown, in the related art, the organic light-emitting layer of the organic light-emitting display panel P is evaporated using an evaporation device C. The evaporation device C includes an outlet, a side wall, a bottom plate and an i...
