Qualcomm unveiled their next-generation Mirasol displays that use a single mirrors to achieve a better color gamut than previous Mirasol displays. These new displays are called SMI (Single Mirror IMOD). Qualcomm showed prototype 5.1" , 2560x1440 (577 PPI) displays.
In SMI-IMOD displays, a single pixel can create all colors - there's no need for three different subpixels as in previous generation IMOD displays. An IMOD (Interferometric Modulator) display shows a color using a mirror film that changes its orientation to create a cavity that interferes with the light. An SMI-IMOD pixel has a mirror that change both its orientation and depth - which enables it to show all colors.
