Are there any technologies that can extend OLED lifetime by improving the quality of the encapsulation layer?
Thin-film encapsulation significantly improves OLED lifetime sustainability by creating a barrier against air and moisture. This layer may be especially beneficial to flexible displays because the various substrates being considered, such as flexible polymers, can be penetrated by liquids and gases. Poor film quality can allow water and air to contaminate the organic layers by diffusion through the substrate. In order to create this barrier, it’s critical to have the appropriate film properties for your application, including an absence of pinholes, as well as your desired level of film density and crystallinity. Various plasma processes allow you to control energy to enable the improved film characteristics that effective encapsulation requires. AE has products that can attain the appropriate energy levels, as well as the arc-management capabilities that prevent arc-caused pinholes. AE’s diverse portfolio features DC, pulsed DC, and RF products that are designed to solve the challenge
