Abstract: An organic light-emitting diode display may contain an array of display pixels. Each display pixel may have a respective organic light-emitting diode that is controlled by a drive transistor. At low temperatures, it may be necessary to increase the amount of current through an organic light-emitting diode to achieve a desired luminance level. In order to increase the current through the light-emitting diode, the ground voltage level may be lowered. However, this may lead to thin-film transistors within the pixel leaking, which may result in undesirable display artifacts such as bright dots being displayed in a dark image. In order to prevent leakage in the transistors, the transistors may be coupled to separate reference voltage supplies or separate control lines. Additionally, the transistors may be positioned to minimize leakage even at low ground voltage levels.

Abstract: The invention provides a device and a method for frequent verifications of the identity of a user performed during a long session of client-server communication by secure exchange of keys between the client and the server. The device is a computer mouse with embedded camera and embedded microphone. The camera is used to make pictures of a user's palm; the microphone is used to register a sound of user's pulse. The method has zero privacy leakage because the user is represented at the server by an array of random numbers, which have nothing to do with his biometric data. The security of the system is difficult to break because the exchange keys are different on each request/response.

Abstract: An input device described herein includes at least one hybrid electrode that is used to perform both capacitive sensing to detect an input object (e.g., a finger or stylus) and force sensing to determine the force applied by the input object on the input device. During a first time period, the input device drives a modulated signal on one more capacitive sensor electrodes to perform capacitive sensing. However, during a second time period, the input device drives a DC voltage across one or more of the capacitive sensor electrodes to perform force sensing. In one example, during the first time period, the input device drives the modulated signal on transmitter electrodes and measures resulting signals on receiver electrodes. During the second time period, however, the input device may drive the DC voltage across the transmitter or receiver electrodes to measure a force applied by the input object.
