Conceptual sketch of a multi-purpose compressive display. The device consists of two high-speed liquid crystal panels covered with an electronically switchable diffuser. With the diffuser being activated, the display is capable of showing superresolved 2D images (left). The diffuser can be deactivated and becomes transparent. In this configuration, the device can emit either a light field for glasses-free 3D display (center) or a high dynamic range image (right).
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.
