ABSTRACT
Qualcomm’s mirasol displays are an alternative to current pervasive flat-panel display (FPD) technology; technologies such as liquid crystal display (LCD) and organic light-emitting diode (OLED) are based on interferometric modulator (IMOD) and utilize microelectromechanical systems (MEMS) elements. These elements modulate 106visible light based on the principles of interference. IMOD technology has unique benefits. Because they are reflective, mirasol displays demonstrate excellent visibility from dim to bright conditions, including direct sunlight. Colour generation is achieved via interference of light, eliminating the need for colour filters or polarizers for either colour generation or light modulation. Additionally, because the switching speed of MEMS pixel elements is intrinsically fast, a variety of refresh rates can be achieved, including video. Early commercialization of mirasol displays has demonstrated the successful transition of these MEMS devices from fabrication at the semiconductor wafer scale to large area manufacturing in what would be considered more conventional FPD fabs.
