摘要： An electronic device includes a cover glass having a display surface, a pixelated photoemitting element array, and a pixelated photodetecting element array. The pixelated photoemitting element array emits a light signal through the cover glass to the display surface. The pixelated photodetecting element array is positioned relative to the pixelated photoemitting element array and the cover glass to receive a reflected light signal. The reflected light signal includes a portion of the emitted light signal reflected by total internal reflection from a refractive boundary at the display surface. Operation of each pixel is switched between the one or more photodetecting elements and the one or more photoemitting elements by the pixel selector signal component received from the pixel selector signal bus. A sensing trigger is configured to trigger the imaging scan by the pixelated photoemitting element array and the pixelated photodetecting element array, responsive to detection of an initiating action.

摘要： A backlight assembly for a display device is provided. The backlight assembly includes a transparent waveguide layer, a plurality of light sources, and a tunable grating layer. The light sources are arranged along an edge of the waveguide layer. Each light source transmits light into the waveguide layer through the edge. The grating layer is coupled to the waveguide layer, and has multiple rows. Each row of the grating layer is segmented into a series of cells so the grating layer is sectioned into an array of cells. Each cell is independently controllable to either not extract incident light received from within the waveguide layer, or to extract the incident light for emission from the backlight assembly. In another configuration, the waveguide layer is not present, and the light sources transmit light directly into an edge of the grating layer.

摘要： The description relates to improving image quality of light emitting diode (LED) displays. Image degradation due to operational ageing, screen burn-in and different ageing speeds of different colours are addressed. One example includes a display, a processor, storage (224), and a pixel run time counter (228). The display can include a set of multiple pixels. Individual pixels can include multiple colour light emitting diodes (LEDs). The processor can be configured to convert image related data (402) into frame renderings for driving the multiple pixels of the display and the storage (224) can be accessible by the processor. The pixel run time counter (228) can be configured to store pixel information for a subset of individual pixels relative to individual frame renderings on the storage. The pixel run time counter may select pixel information to be stored depending on pixel changes between consecutive frames (404). The stored pixel information from multiple subsets of individual pixels of the frame renderings can collectively reflect time and intensity parameters that the frame renderings have driven the set of pixels.

摘要： The description relates to display device image quality. One example can include a display (226), a processor, storage (224), a pixel run time counter (228), and a pixel effective age compensation component (230). The display can include multiple pixels. Individual pixels can include multiple different colored light emitting diodes (LEDs). The processor can be configured to convert image related data into frame renderings (402) for driving the multiple pixels of the display. The pixel run time counter (228) can be configured to store pixel information (302) on the storage (224) that reflects time and intensity parameters at which the frame renderings have driven the multiple color LEDs of the individual pixels in the frame renderings. The frame compensation component (406) can be configured to receive a new frame rendering and to generate an adjusted frame rendering that compensates for luminance degradation of individual pixels based at least upon the stored pixel information (302).

摘要： An image decoding system provides a phase pattern encoding a target image. A spatial light modulator is configured to emit a wavefront-shaped light signal based on the phase pattern. A first diffusive medium receives the wavefront-shaped light signal and to emit a decoded scattered light signal of the target image. The target image is previously encoded in the phase pattern by transmitting another wavefront-shaped light signal shaped by a training phase pattern through a second diffusive medium to yield a scattered light signal encoding a test image. The second diffusive medium has the optical scattering characteristics of a first diffusive medium. The scattered light signal encoding the test image is emitted from the second diffusive medium and recorded. The training phase pattern is adjusted for successive iterations of the test image until the test image satisfies a compensation condition. The resulting training phase pattern yields the phase pattern.

摘要： An electronic device includes a transparent cover and a light source disposed at an edge of the transparent cover. The light source is configured to inject light into the transparent cover. The transparent cover guides the light until interaction with a fingerprint ridge at the transparent cover. The electronic device further includes a filter disposed along the transparent cover. The filter is configured to selectively allow the light scattered by the fingerprint ridge to pass through the filter. A detector generates a signal indicative of the scattered light allowed through the filter.
