Abstract
A mobile computing device includes an emissive display panel, where the panel is used as a grating, and spectrometer optics positioned behind/below the emissive display panel. A mobile computing device includes an emissive display panel and a spectrometer positioned below the emissive display panel. The emissive display panel includes a first periodic pattern of pixels that include one or more LEDs and a second periodic pattern of circuit elements that control the pixels, where the first and second periodic patterns are configured to diffract light received from outside the device, which passes through the emissive display, and where the diffraction is wavelength-dependent. The spectrometer is configured to detect intensities of different wavelength ranges of the diffracted light.
