Double-layer Fabry–Pérot filter interferometric modulator display

Presented is an interferometric modulator display characterized by double layers of liquid crystal (LC) Fabry–Perot filters. With this design, no polarizers and color filters are needed, and both the color and amplitude can be tuned by electrically controlling the LC's birefringence. Instead of the conventional RGB trisubpixel color scheme, a bisubpixel structure is proposed to render a super-wide color gamut. Through simulations, the device performance was numerically studied. The device was proven to be quite suitable for green-display application.
