Atmospheric Pressure Plasma Display Panel Printing Application | PSM

PSM Co., Ltd. has led the development of atmospheric pressure plasma technology through constant technological innovation for more than 20 years since its foundation in 2001.

Atmospheric pressure plasma is suitable for a wide range of applications. Primarily, it is well useful for pre-treatment of different surfacescleaning and activation of polymers, metals, ceramic, and glass, and hybrid materials.

Atmospheric pressure plasma is often also called AD plasma or normal pressure plasma. The name comes from the fact that the pressure at which it is produced is approximately the same as that of the surrounding atmosphere, the so-called normal pressure. In contrast to low or high-pressure plasma, there is no need for a reaction vessel to maintain the different pressure levels to atmospheric pressure.Vacuum plasma technique

Atmospheric pressure plasma is mainly used at low current density for surface activation and fine cleaning of plastic, metal, or inorganic materials. In the industrial sector, plasma treatment is mainly used for the pre-treatment of surfaces prior to gluing, printing, and painting processes. In the medical sector, it is increasingly used for disinfection and sterilization.

The advantage of treatment with atmospheric pressure plasma is that liquid chemicals can be completely dispensed with. Only electricity and carrier gas are required. All in all, in this type of plasma generation, compressed air or other harmless gases such as nitrogen or forming gas can be used as well as in the case of piezoelectric discharge noble gases and even ambient air.

PSM M-Plasma Series is a high-efficiency atmospheric pressure plasma module. It is mainly used for surface fine cleaning and surface refinement, especially ideal for surface treatment of glass, plastics, and polymer.

PSM Plasma Application to Display Panel Printing:

PSM AP plasma is applicable to OLED RGB /Quantum Dot Display inkjet process and AP plasma is applied to the Nano-imprinting pre-treatment/primer removal process as well.

AP Plasma Electrode can be applied to the selective surface treatment process before inkjet printing for the OLED RGB Pattern /Quantum Dot Display. It can be stable applied to large samples (6~10G) as well with processing speed of 6-8m/min.

PSM vacuum plasma is applicable to Descum/Etching for the patterning process.

• The PSM vacuum plasma system uses a unique vacuum and gas flow technology
• The best resin removal system and etching equipment are provided
• It is applied to the Descum process for the purpose of removing the resin on the substrate surface
• It is applied to glass etching for forming Nano-imprinting patterns
