EPD and MIP: Masters of Efficiency

For a specific subset of wearables, particularly those prioritizing weeks-long battery life and supreme sunlight readability, Memory-in-Pixel (MIP) displays and E-Paper Displays (EPD) are the technologies of choice. EPD, best known from popular e-readers, is reflective, meaning it uses ambient light and consumes power only when the image is changed. This makes it perfect for devices that need to display static information like time, steps, or notifications for extended periods without a recharge. MIP is a variation on LCD that integrates memory storage into each pixel, drastically reducing power consumption by only refreshing the display when the content changes. These technologies sacrifice color and motion performance for unparalleled efficiency.

Microdisplays for AR: LCoS, DLP, and Waveguides

The world of Augmented and Virtual Reality headsets operates on a different scale, utilizing microdisplays that project images directly onto the user's retina or into waveguides. Technologies here include Liquid Crystal on Silicon (LCoS), Digital Light Processing (DLP), and OLED-on-Silicon. These tiny, high-resolution panels are marvels of engineering, capable of creating immersive digital overlays on the real world. Their development is arguably the most technically challenging frontier of the wearable display market, requiring breakthroughs in brightness, resolution, and form factor to become truly mainstream.
