US 2018/0025200 A1 · LUMINESCENT FILM WITH QUANTUM DOTS

Abstract

One or more techniques and/or systems are disclosed for a luminescent film that can be used with a biometric imager, which can be used to scan biometric markers, and/or to interact with the device. Upon contacting a device surface, an image of at least a portion of the touch object can be captured and used in conjunction with identification of the user and/or for input to the device. The systems or techniques, described herein, may be integrated into a portion of a device, and may comprise a luminescent layer, comprising quantum dots, that can emit photons upon contact, and an image capture component that can generate data indicative of an image of at least a portion of the touch object.

Dependent claims

A system for producing a relief print image, comprising:

a relief print data generation component to generate relief print data comprising an indication of light from a light emitting layer received by a sensor array, the relief print data generation component comprising:
the sensor array to convert received photons to an electrical signal indicative of the relief print data;
and
the light emitting layer comprising quantum dots to provide electroluminescence, the light emitting layer operably disposed above the sensor array to emit photons from the quantum dots toward the sensor array, the photons indicative of one or more portions of a relief object disposed above the light emitting layer;
and
an image generation component operably coupled with the relief print data generation component to convert the relief print data into image data indicative of a relief print image.
