A New Type of Low-light OLED Display with Day-night Mixed Light Mode
This paper introduces a novel dual-redundant mixed-light night vision compatible backlight module,which features a double-redundant staggered arrangement of white OLED and colored OLED.The backlight guiding plate is designed with two layers stacked together,with the upper guiding plate corresponding to the color light and the lower guiding plate corresponding to the white light.These two layers of guiding plates are bonded together using optical adhesive.White light and color light each have their own dimming circuits,and the switch between them is based on the day-night mode.The white and color lights are interleaved on an aluminum substrate,which is placed into an acrylic structure and assembled with sealing adhesive to the upper and lower sides of the double-layer guiding plates.Various optical films,including diffusion films,BEF brightening films,and DBEF brightening films,are inserted between the white glass and the night vision filter.Once the optical film combination is com-plete,adhesive tape is applied around the optical film assembly to secure it,and then the double guiding plates are bonded to the night vision glass.
