Abstract: Disclosed is a vapor deposition apparatus comprising an adsorption apparatus disposed in a vapor deposition cavity, wherein the adsorption apparatus comprising: a plurality of magnetic blocks arranged in a matrix disposed on a side of a substrate to be vapor deposited away from a metal mask plate, and a towing apparatus for adjusting each of the magnetic blocks to move up and down relative to the substrate to be vapor deposited. Such a vapor deposition apparatus may cause the metal mask plate to closely fit the substrate to be vapor deposited, such that a correct pattern will be formed when sub-pixel units are vapor deposited, and cause the magnetic fields of all the magnetic blocks to tend to be consistent, avoiding affecting the above-mentioned pattern by a deformation of the metal mask plate due to the inhomogeneity of the magnetic fields.

Abstract: Disclosed is a metal mask configured to act as a mask of a substrate in a vacuum evaporation process. The metal mask comprises a mask pattern and a plurality of alignment openings, wherein an extending direction of the alignment openings in the metal mask is not coincident with a perpendicular direction (M) of a plane where the metal mask is located, and the alignment openings do not penetrate through the metal mask (100). Since the light is reflected for several times and partly absorbed within the alignment openings, images as generated by the CCD system according to the alignment openings of the metal mask and the alignment mark of the substrate have significant color contrast therebetween, thus, they are easily distinguished, which may reduce the alignment difficulty and alignment error.

The power supply circuit is configured to apply a control voltage signal to a control end of the temperature-sensitive element. The temperature-sensitive element is configured to, under the control of the control voltage signal, generate a temperature-related voltage, and output the temperature-related voltage via a first end of the temperature-sensitive element, and a value of the temperature-related voltage changes along with an ambient temperature of the temperature-sensitive element. The output circuit is configured to output a temperature-adaptive voltage via the first voltage output end. A difference between a value of the temperature-adaptive voltage and the value of the temperature-related voltage is within a predetermined range.
