Abstract
Exemplary methods, apparatuses, media, and arrangements enable the implementation of one or more features in electronic devices that have (e.g., display) screens that are capable of light emission and detection. These features include, for example, scanning, (simulated) touch-screen sensitivity, and ambient light determination and compensation. The display screens may be comprised of light emitting/detecting elements, such as diodes, that can emit light for visual display and can detect light for receiving light information data. In certain described implementations, a method for implementing a feature using a display screen with emitting/detecting elements includes the actions of: activating multiple elements of an array of elements to emit light; activating multiple elements of the array of elements to detect light; producing detected light data representing the light detected by the multiple elements that are activated to detect light; and processing the detected light data to implement the feature.
