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.

Abstract: A display configuration to facilitate imaging through the display is disclosed. The imaging can be achieved by positioning a camera behind a transmit/receive area (120,122) of a display. The transmit/receive area is configured to reduce the interaction between the light propagating through the display and circuit elements of the display. The configuration of the transmit/receive area can be characterized by reduced pixel density, rearranged circuit elements (1242), and as light blocking layer (1222, 1260) to prevent light from diffracting from gaps formed by circuit elements (1242).

Abstract: A display configuration to extend the light emitting and touch sensitive portion of a display panel into areas normally reserved for other light devices is disclosed. In the configuration, light devices and the display panel are configured to operate together. The display panel may include an aperture through the display panel to provide an unobstructed light path to a light device. The display panel may also include a routing area to provide space for data lines feeding pixels to be rerouted around the aperture. The routing area is partially obstructed by data lines but otherwise transparent. Accordingly, some display devices may be positioned behind the routing area and still operate.

Abstract: A display configuration to facilitate imaging through the display is disclosed. The imaging can be achieved by positioning a camera behind a through-transmissive area of a display. The through-transmissive area is configured to reduce the interaction between the light propagating through the display and circuit elements of the display. The configuration of the through-transmissive area can be characterized by reduced pixel density, rearranged circuit elements, and a light blocking layer to prevent light from diffracting from gaps formed by circuit elements.

Abstract: This document describes systems and techniques directed at expediting fingerprint authentication via variable refresh rate control and display luminance compensation. In aspects, a computing device having an under-display fingerprint sensor (UDFPS) and a touch-sensitive display includes a biometric authentication manager. Upon detecting at least one finger at or near the touch-sensitive display, the biometric authentication manager implements variable display refresh rates and selectively adjusts luminance settings for a high-luminance region of the touch-sensitive display for predetermined intervals. In so doing, at least one finger can be well-illuminated during UDFPS image capturing, facilitating UDFPS sensing and expediting fingerprint authentication.

Abstract: A mobile computing device includes an emissive display panel configured to emit light from a front surface of the display panel, with the display panel having a plurality of transparent layers and an opaque back cover layer. The mobile computing device also includes a light sensor located behind the opaque back cover layer, and the opaque back cover layer includes an opening through which light from outside the display that is transmitted through the transparent layers of the display can pass to reach the sensor. An air gap separates the light sensor from the transparent layers of the display panel. The plurality of transparent layers includes a reflection attenuating layer on a back side of the display panel configured to attenuate the reflection of light from an interface between a transparent layer of the display panel and the air gap.
