Recently, the display device was developed to apply to the transparency display device(TDD), but the TDD was no brightness. The purpose of this paper was introduced a double layer optical film to improve luminance of the TDD. The film was doped micro metal oxide particles to increase the effect of scattering and refraction, and the micro structure was fabricated between the top and bottom film to enhance the light into the TDD. This research provided a transparent double layer optical film. The transparency of the film was achieved to 70 %, and the brightness efficiency up to 60 %.
OLEDs(Organic Light Emitting Diodes) has been applied to lighting and display fields. OLEDs has many advantages such as no viewing angle and fast reaction rate and so on. However, OLEDs still has low brightening issue in lighting field. This research fabricates a simple and fast production line, to produce light extraction film of the OLED. Microparticles in light extraction film were provided to enhance light luminance efficiency of the OLED up to 90%. A simple and fast production line was designed and fabricated by mechanical processing mode. It can produce 20 pieces light extraction films within 1hour.
