Abstract: To reduce the effect of external light and to improve the accuracy of detecting the location of a touch. In an image-capture period, light emission from a self-light-emitting element is controlled, and imaging data at the time of displaying white on a display screen and imaging data at the time of displaying black on the display screen are output from each sensor pixel. The location of a sensor pixel where a difference between the two pieces of imaging data output from the same sensor pixel is the greatest is detected. Thus, the location of a touch of the object on the display screen is detected with high accuracy. By utilizing a difference between imaging data at the time of reverse display, the effect of external light can be reduced.

Abstract: The invention relates to movement detection apparatus (1) for detecting a hand movement like a hand gesture which may be used for controlling a computer or another device. A light emitting device emits light into tissue at the wrist (5) of a person and a light detection device detects light, which has travelled through the tissue, at the wrist and generates a light detection signal based on the detected light, wherein a hand movement determination unit determines the hand movement based on the light detection signal. When the hand moves, i.e., for instance, when it rotates or when a finger moves, the composition of the tissue, through which the light travels, and hence the light detection signal change. This change in the light detection signal can be used to reliably determine the respective movement of the hand in a way which is very convenient for the person.

Abstract: Various timing schemes can be used to synchronizing display functions with touch and/or stylus sensing functions for devices including a variable refresh rate (VRR) display. In a continuous-touch mode, for example, extended blanking can result in frame judder due to mismatch or latency between reporting of sensing data and the display. To minimize these issues, sensing operations can reset to re-synchronize with the display operation, and unreported data from sensing scans can be discarded or ignored. In some examples, a display frame can be divided into two sub-frames, and a system can be configured to perform a touch sensing scan during the first sub-frame of a display frame. At the conclusion of extended blanking, the sensing operations can reset to re-synchronize with the display. The touch sensing scan can be completed in one intra-frame pause and can begin at the start of the display frame.
