摘要
Aspects disclosed herein relate to color filters for display devices, and more specifically to color filters for transmitting or reflecting and recycling colors of light in liquid crystal display devices. In one aspect, a metasurface is formed between two polarizers in an LCD device. In another aspect, a metasurface is formed on a white light guide of an LCD device. The metasurface is formed to transmit desired color(s) of light and to reflect undesired color(s) of light back into the light guide to be recycled and passed through the LCD device elsewhere. Using the color filter to recycle reflected colors of light increases the efficiency of the display device, such as the LCD device.
