摘要： Systems and methods are provided for optimizing battery life in an electronic device. The device is configured to make periodic assessments of battery capacity by measuring the DC resistance value of the battery cell during the execution of a power-consuming operation. If the measured DC resistance value reaches a threshold level, the device can initiate a power-saving mode in which an operating parameter of the device is adjusted to decrease power consumption.

摘要： This disclosure provides systems, methods, apparatus, and computer readable media for generating images on a display using a dithering process that takes into account an uneven spacing of available gray scale values in at least one color subfield used to generate the images. The dithering process includes generating a set of initial color subfields, a set of quantized color subfields, and a set of final color subfields, which are then output on the display. The quantized color subfields an the final color subfields are derived based at least in part on the uneven spacing of gray scale values in at least one of the final color subfields.

摘要： This disclosure provides thin film transistors (TFTs) including p-n hetero-junction structures. A p-n hetero-junction structure may include a junction between a narrow bandgap material and a wide bandgap material. The narrow bandgap material, which may be an oxide, nitride, selenide, or sulfide, is the active channel material of the TFT and may provide relatively high carrier mobility. The hetero-junction structures facilitate band-to-band tunneling and suppression of TFT off-currents. In various implementations, the TFTs may be formed on flexible substrates and have low temperature processing capabilities.

摘要： Systems and methods for displaying always-on content on a display of a mobile device allow the device to use a low power processor for certain always-on content and to coordinate with the device application processor for the remaining always-on content. In an embodiment, a pixel row-skip pattern is specified by the low power processor based on the display screen's resolution setting as well as ambient light conditions. In a further embodiment, the execution of pixel rendering in keeping with the prescribed pattern is synchronized between the device's low power processor and main application processor.

摘要： The current disclosure is directed to systems and methods that process standard video signal data and that control a reflective display panel to brightly display videos and images in colors selected from a broad range of colors. In certain implementations, an input video/image signal is first transformed from a RGB encoding to an encoding based on a new color system that encodes colors using spectral, black, and white components. The reflective display panel includes an array of pixels, with each pixel comprising one or more self-parallelizing interferometric modulators (“SPIMs”). Each SPIM contains a plurality of electrodes disposed on a bottom plate, a fixed top plate, and a movable plate separated by a cavity. Appropriate voltages are applied to the electrodes to vary the cavity depth of the SPIM in order for the SPIM to reflect a color of a particular wavelength or to appear black or white.
