A display device is provided that includes a display panel and a backlight panel. The backlight panel includes a plurality of self-calibrating illumination modules configured to provide backlighting for the display panel. Each self-calibrating illumination module includes at least one light source configured to emit light toward the display panel, at least one light sensor configured to detect light emitted from the at least one light source that is internally reflected within the display device, and a controller configured to control a current supplied to the at least one light source based at least on an intensity of light detected by the at least one light sensor.

Self-calibrating illumination modules for display backlight

Described are examples of display devices including a display panel comprised of a transparent layer, a color filter layer adjacent to the transparent layer, wherein the color filter layer comprises a matrix of colored light filters, and a black matrix layer comprising a base portion disposed on the transparent layer between two of the different colored light filters and an extension portion that extends into the color filter layer between the two colored light filters to block a light path that may otherwise traverse both of the two colored light filters. The base portion and the extension portion differ in a height dimension that is substantially perpendicular to the transparent layer.

Black matrix structures for displays devices

The present disclosure provides devices and techniques for dynamically adjusting the bias voltage (V) levels (e.g., low level gate voltage (VGL) and high level gate voltage (VGH)) for display screens made with thin-film transistor (TFT) technology based on a display run time. Thus, as the positive bias temperature stress for the TFTs increases over the course of the display lifetime, features of the present disclosure adjust the bias voltage levels to maintain operation margin (e.g., the ratio between the high level gate voltage (VGH) value and the voltage value which the display can maintain with normal operation). By dynamically adjusting the bias voltage levels, the TFT displays of the present disclosure consume lower power than their conventional counterparts and improve the lifetime of the display itself.

Techniques for robust reliability operation of a thin-film transistor (TFT) display

An electronic device includes a first digital-to-analog converter (DAC) configured to provide brightness control for a first subset of pixels of a display and a second DAC configured to provide brightness control for a second subset of pixels of the display. A display controller selectively operates the second DAC to provide the brightness control for the second subset of pixels while simultaneously operating the first DAC to provide the brightness control for the first subset of pixels of the display.

Localized high brightness mode

Conductive trace routing techniques for display and bezel sensors are described. In one or more implementations, an apparatus includes display sensors, bezel sensors, and a plurality of conductive traces. The display sensors are configured to detect proximity of an object and are arranged in conjunction with a display area of a display device to support interaction with a user interface displayed by the display device. The bezel sensors are configured to detect proximity of an object and are disposed in a bezel that at least partially surrounds the display device and is outside the display area. The plurality of conductive traces are disposed between the display and bezel sensors and communicatively couple the display sensors and the bezel sensors to one or more computing components that are configured to process inputs received from the display sensors and the bezel sensors.
