\”Mirasol screen\” by Qualcomm, image/information source: Qualcomm
Mirasol screens refer to a reflective display technology developed by Qualcomm, using interferometric modulator (IMOD) elements based on MEMS (micro-electro-mechanical systems). They mimic butterfly wing coloration by reflecting ambient light through tiny adjustable mirrors, enabling color, video playback, and sunlight readability with minimal power use due to bistability.
Technology Basics
These displays feature pixels with a reflective membrane and thin-film stack separated by an air gap. Applying voltage collapses the gap, switching from color reflection to black absorption via light interference. This bistable design holds images without power, ideal for low-energy devices like e-readers.
Key Advantages
- Sunlight-readable without backlighting, unlike LCDs.
- Supports 60 Hz video refresh rates, faster than e-ink.
- Near-zero static power draw, extending battery life.
History and Status
Launched around 2010 for e-readers and mobiles, Mirasol faced challenges like washed-out colors and battery drain in video mode. Development stalled by mid-2010s; no widespread consumer adoption occurred, though prototypes showed promise.
Modern Context
A separate product, MiraSol Drop Screens by Sol-Lux, offers motorized outdoor shading unrelated to displays. Qualcomm\’s site archives the tech, with no active consumer products as of 2026.
