Abstract

This disclosure provides systems, methods and apparatus for touch and gesture recognition, using a field sequential color display. The display includes a processor, a lighting system, and an arrangement for spatial light modulation that includes an array of light modulators. Each light modulator is switchable between an open position that permits transmittance of light from the lighting system through a respective aperture and a shut position that blocks light transmission through the respective aperture. The processor switches the light modulators in accordance with a first modulation scheme to render an image and in accordance with a second modulation scheme to selectively pass object illuminating light through at least one of the respective apertures. A light sensor receives light resulting from interaction of the object illuminating with an object and outputs a signal to the processor. The processor recognizes, from the output of the light sensor, a characteristic of the object.

Description

[0001] priority claim [0002] This application claims U.S. Patent Application No. 14 / 034,374, filed September 23, 2013, and entitled "INTEGRATION OF A LIGHT COLLECTION LIGHT-GUIDE WITH A FIELD SEQUENTIAL COLORDISPLAY" priority, said US patent application is hereby incorporated by reference. technical field [0003] This disclosure relates to techniques for touch and gesture recognition, and more particularly to field sequential color (FSC) displays that provide a user input / output interface that is controlled in response to user touches and / or gestures. Background technique [0004] Electronic devices, such as smart phones, tablet computers, laptop computers, personal computers, etc., increasingly feature touch screen user interfaces. The power, cost, and durability requirements typical of handheld devices are not well met by known technologies. For example, projected capacitance touch (PCT), the technology most commonly used today for handheld devices, typically uses la...
