Abstract: The amount of power and processing capacity needed to process gesture input for a computing device can be reduced by utilizing one or more relatively low power, low resolution gesture sensors. The gesture sensors can have relatively large pixels, which provide enhanced sensitivity in low light situations. Further, the low resolution and high frame rates of the gesture sensors can enable relatively low bandwidth buses to be used, rather than dedicated image buses. These low bandwidth buses can conserve a significant amount of power, and can provide the image data from the gesture sensors to low power PIC-class microprocessors, or other such components, which can analyze image data and make basic gesture determinations without having to wake up an application processor or send data over a main bus, which can further reduce power consumption.

Abstract: A system and method for allocating power to a plurality of displays is disclosed. An exemplary system preferably includes an AC current sensor, a power load sharing controller, ambient light sensors for each display, and a brightness controller for each display. A maximum total current draw may be selected. The ambient light contacting each display may be measured and a corresponding desired brightness calculated. Depending on the present amount of current draw, the system determines if the displays can be driven at the desired brightness without exceeding the maximum total current draw. If yes, the displays are driven at their desired brightness. If no, the desired brightness for each display may be slightly reduced to prevent exceeding the maximum total current draw. Thus, as the ambient light varies between the displays, the available power may be shared.

In response to detecting a predetermined pressure change of a single contact on the trackpad, the single contact is ignored.

Abstract: A display driver maps a selection code (a digital signal) to a reference voltage which is then used to produce a particular intensity of the radiation emitted from a pixel on a display screen (e.g., a LCD display). This mapping may be performed by one or more DACs in the display driver. However, instead of transmitting all of the different possible reference voltages to the DACs, only a subset of the reference voltages are transmitted. Each DAC may include an interpolator circuit that uses the received reference voltages to interpolate the reference voltages that were not transmitted. In this manner, the display driver may still provide the same number of unique reference voltages to a display screen while transmitting fewer reference voltages along the driver's optical channel.

Sub-frame periods of the plurality of sub-frames are determined based on a predetermined resolution of the image. The plurality of sub-frames have sub-frame periods that differ from one another. A plurality of unit pixels are initialized by applying a common voltage to a common electrode and by applying a first voltage to a plurality of pixel electrodes. Each pixel electrode corresponds to a respective one of the plurality of unit pixels. Gray levels of the plurality of unit pixels are controlled by selectively applying one of the common voltage and a second voltage to each pixel electrode during each sub-frame.
