Abstract: An electronic device may be provided with electronic components such as a touch screen display. The touch screen display may be controlled based on information from a proximity sensor. The proximity sensor may have a light source that emits infrared light and a light detector that detects reflected infrared light. When the electronic device is in the vicinity of a user's head, the proximity sensor may produce data indicative of the presence of the user's head. Variations in proximity sensor output due to user hair color and smudges on the proximity sensor can be accommodated by using a dynamically adjustable proximity sensor data threshold in processing proximity sensor data. Proximity sensor data may be analyzed in real time to detect signal strength fluctuations that are indicative of the presence of low-reflectively dark hair on the user's head. Threshold adjustments may be based on the presence of dark hair.

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: It is an object to provide a transmissive liquid crystal display device in which power consumption is reduced and deterioration in display quality is suppressed. As a backlight, a surface-emission light source is employed. The light source is a light source which performs surface light emission, so that the light emission area is large. Accordingly, the backlight can effectively radiate heat. Thus, even in the case where an image signal is not input to a pixel for a long period, the pixel can hold the image signal. In other words, both a reduction in power consumption and a suppression of deterioration in display quality can be realized.
