Slow Display


How can we show our 16-megapixel photos from our latest trip on a digital display? How can we create screens that are visible in direct sunlight as well as complete darkness? How can we create large displays that consume less than 2W of power? How can we create design tools for digital decal application and intuitive-computer aided modeling? We introduce a display that is high-resolution but updates at a low frame rate: a slow display. We use lasers and monostable light-reactive materials to provide programmable space-time resolution. This refreshable, high-resolution display exploits the time decay of monostable materials, making it attractive in terms of cost and power requirements. Our effort to repurpose these materials involves solving underlying problems in color reproduction, day-night visibility, and optimal time sequences for updating content.
