Abstract

The invention provides an organic vapor deposition device and a control method thereof, and relates to the technical field of display. The organic vapor deposition device and the control method thereof aim at solving the problem of rapidly dredging a blocked nozzle during deposition. The organic vapor deposition device comprises an organic material supplying device, and a plurality of injecting heads which are connected to the organic material supplying device, wherein each injecting head comprises a pressurizing device, nozzles and lasers; the nozzles and the lasers are arranged at two opposite sides of the pressurizing device; the organic material supplying device is used for conveying output deposition air between the lasers and the nozzles; the lasers are used for emitting laser rays to the nozzles; and the pressurizing device is used for pressurizing the deposition air conveyed by the organic material supplying device and then injecting out the air through the nozzles.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic vapor deposition device and a control method thereof. Background technique [0002] Currently, optoelectronic devices made of organic materials are favored, and many of the materials used to make such devices are relatively cheap, so organic optoelectronic devices have a potential cost advantage over inorganic devices. In addition, the inherent properties of organic materials, such as their flexibility, can make them well suited for specific applications, such as fabrication on flexible substrates. Examples of organic optoelectronic devices include organic light-emitting diodes (Organic Light-Emitting Diode, OLED for short), organic phototransistors, organic photovoltaic cells, and organic photodetectors. For OLED devices, organic materials can have performance advantages over conventional materials. For example, the wavelength at which an organic emissive layer emi...
