Abstract

The invention provides a cooling plate and an evaporation device and belongs to the technical field of display. The cooling plate comprises a cooling plate body. The cooling plate body comprises a cooling face with a cooling function. Protrusions are arranged on the cooling face. By the adoption of the cooling plate and the evaporation device, the problem that during position alignment and overlapping of the cooling plate and a glass substrate, electrostatic adsorption force can be generated between the cooling plate and the glass substrate, and consequently the glass substrate is scratched easily by the cooling plate is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a cooling plate and an evaporation device. Background technique [0002] Organic Light-Emitting Diode (English: Organic Light-Emitting Diode, referred to as: OLED) display devices are more and more widely used due to their many advantages such as active light emission and fast response speed, and OLED display devices are usually manufactured using evaporation devices. [0003] Such as figure 1 As shown, the evaporation device 10 generally includes: an evaporation chamber 101 , a crucible 102 , a mask plate 103 and a cooling plate 104 , wherein the material of the cooling plate 104 is generally a metal material with a rough surface and burrs. The OLED display device includes a glass substrate 20, and an evaporation material ( figure 1 not shown). When using the evaporation device 10 to form the evaporation material on the glass substrate 20 , it is necessary to firstly fill th...
