Abstract: An organic light emitting pixel compensation circuit, an organic light emitting display panel, and a driving method are provided. The organic light emitting pixel compensation circuit includes an external compensation module, which has a data line, a reference voltage line, a reset control line, a first detection control line, a second detection control line, a first input/output terminal, a second input/output terminal, a reset unit, a threshold voltage detection unit, a deterioration voltage detection unit, a data processing unit, and an adder unit. The deterioration compensation for a light emitting element is achieved by detecting and processing an anode voltage at the second input/output terminal to obtain a compensated voltage, and feeding the compensated data voltage back to a gate of a driving transistor via the data line.
Abstract: A touch-control display device includes a driving module, a display panel having a first force touch-control component and a self-capacitance type touch control-electrode, and a backlight module disposed with the display panel and having a second force touch-control component, with a variable gap formed between the first force touch-control component and the second force touch-control component. The first touch-control component comprises a plurality of first electrodes arranged in a matrix. The second force touch-control component is an electrical conductive layer. The self-capacitance type touch-control electrode comprises a plurality of second electrodes arranged in a matrix.
Abstract: A haptic driving apparatus provides a user with electrovibration of certain strength regardless of a variance of a surrounding environment, and an electronic device has a haptic function. The haptic driving apparatus comprises a haptic electrode driver generating a haptic driving signal to supply the generated haptic driving signal to a haptic electrode through a current monitor and varying the haptic driving signal in accordance with voltages at both ends of the current monitor.

Abstract: One aspect of the invention relates to an exemplary method for measuring latency of display response of a touch screen on a touch screen based device, comprising recording, by a video camera, an interaction with the touch screen, correlating, by a processor in operative communication with the video camera, data retrieved from the recording to the interaction; and determining, by the processor, a latency of the response of the touch screen to the first contact. An interaction may comprise at least a first contact between a member and the touch screen, and a response of the touch screen to the first contact, including at least a first change of a frame of a display of the touch screen.

Abstract: A method of recognizing an aimed point on a plane is provided. Images captured by one or more image sensor are processed for obtaining data obtaining data indicative of location of at least one pointing element in the viewing space and data indicative of at least one predefined user's body part in the viewing space; using the obtained data an aimed point on the plane is identified. In case it is determined that a predefined condition is met a predefined command and/or message is executed.
