The driving unit (12) outputs a driving current to the display unit (14) via an output terminal (d3) under control of the control voltage and the operating voltage. The display unit (14) is driven to emit light by the driving current under control of the fifth scanning signal terminal (S5). By using the touch display circuit, photosensitive in cell touch technology can be integrated into an AMOLED display.

A door handle including light emitters for emitting light out of the handle, light detectors, lenses oriented relative to the emitters and detectors such that for each emitter-detector pair, when a reflective object is located at a target position near the handle, corresponding to that emitter-detector pair, then the light emitted by that emitter passes through one of the lenses and is reflected by the object back through one of the lenses to that detector, a keyless lock that, when activated, scans for a digital key via wireless communication, and a processor operable to synchronously activate emitter-detector pairs, to recognize from the amounts of light received by the activated detectors, and from the target positions corresponding to the activated emitter-detector pairs, that the object is approaching the handle and performing a sweep gesture and, in response thereto, to activate the keyless lock.

Systems and techniques for providing a three-dimensional touch screen are described. Example systems include a touch screen manager that is configured to display a screen via a display device, such as by projecting on a wall or other surface a screen generated by a computing device, such as a desktop, laptop, or tablet computer. The manager is further configured to receive position information from a sensor that determines the positions of objects, such as the finger or hand of a user, within a three-dimensional space in front of the display surface. The manager then converts the received position information into user interface events, including gestures (e.g., pinch, swipe), mouse-type events (e.g., click, drag), or the like. The user interface events are provided to an application or other module executing on the computing device.

An input device includes an input interface, a power module, a wireless charging module, a solar charging module and a controller. The power module provides electricity to the input device. The wireless charging module is used for wirelessly charging an electronic device. The solar charging module is used for charging the power module or providing electricity to the wireless charging module. When the controller detects that an electricity quantity percentage of the power module is lower than a predetermined value, the controller controls the solar charging module to charge the power module. When the electronic device is in communication with the input device, the controller controls the solar charging module to the provide electricity to the wireless charging module, and the electronic device is wirelessly charged by the wireless charging module if the electronic device is within a charging range.
