Abstract
Compressive displays are an emerging technology exploring the co-design of new optical device configurations and compressive computation. Previously, research has shown how to improve the dynamic range of displays and facilitate high-quality light field or glasses-free 3D image synthesis. In this paper, we introduce a new multi-mode compressive display architecture that supports switching between 3D and high dynamic range (HDR) modes as well as a new super-resolution mode. The proposed hardware consists of readily-available components and is driven by a novel splitting algorithm that computes the pixel states from a target high-resolution image. In effect, the display pixels present a compressed representation of the target image that is perceived as a single, high resolution image.

We explore a new compressive display design that can be switched between light field, high dynamic range, and superresolution modes
It is the first design that can be reconfigured on the fly between three radically different display modes: superresolution, glasses-free 3D, and 2D high dynamic range
Summary
Introduction and Related WorkThroughout the last few years, display technology has undergone a major transformation. Many recently proposed approaches integrate different images optically by superimposing multiple projections on the same screen [8, 9] This can be achieved in single display/projector designs using mirrors [10] or by displaying different patterns on a quickly moving device [11, 12]. One solution that overcomes these problems is Optical Pixel Sharing (OPS) [13], which uses two LCD panels and a ‘jumbling’ lens array in projectors to overlay a high-resolution edge image on a coarse image to adaptively increase resolution This way only the most strongest edges are improved adaptively, while smooth areas are unchanged. It is not immediately obvious how such approaches could be adapted from projectors to flatpanel displays
