ABSTRACT
This chapter discusses the basic electromechanical physics of the mirasol display, principles of interferometric colour generation and modulation and device fabrication and manufacturing. It demonstrates how materials and tools available from thin-film transistor display industry are being applied to the fabrication of mirasol display. The chapter also discusses front-of-screen components, with a particular focus on touch input interface and supplemental illumination needed for reflective displays in darker ambient conditions. Qualcomm's mirasol displays are an alternative to pervasive flat-panel display technology; technologies such as liquid crystal display and organic light-emitting diode are based on interferometric modulator and utilize microelectromechanical systems elements. These elements modulate visible light based on the principles of interference. The most important consideration in the design of a product based on the mirasol reflective display is managing the light path to and from the display. The highest display contrast is the result of minimizing reflections from the surfaces in front of the display elements.
