    摘要： A technique to implement a stable and high impedance current sink or source onto a display substrate using a single device. The high output current source or sink circuit includes an input that receives a fixed reference current and provides the reference current to a node in the current source or sink circuit during a calibration operation of the current source or sink circuit. The circuit further includes a first transistor and a second transistor series-connected to the node such that the reference current adjusts the voltage at the node to allow the reference current to pass through the series-connected transistors during the calibration operation. The circuit includes one or more storage devices connected to the node, and an output transistor connected to the node to source or sink an output current from current stored in the one or more storage devices to a drive an active matrix display with a bias current corresponding to the output current.

    摘要： Circuits for programming a circuit with decreased programming time are provided. Such circuits include a storage device such as a capacitor for storing display information and for ensuring a driving device such as a driving transistor drives a light emitting device according to the display information. The present disclosure provides driving schemes for decreasing flickering perceived while displaying video content by introducing idle phases in between in emission phases to increase the effective refresh rate of a display. Driving schemes are also disclosed for reducing the effects of cross-talk by ensuring that programming information is refreshed in a display array that utilizes a driver connected to multiple data lines via a multiplexer.

    摘要： Switching of power modes for touch screens is disclosed. In example embodiments a touch detect mode may be activated for touchscreen operation. The touchscreen may be a projected capacitance screen that includes force sensing based on piezo electric sensors. The touch detect mode may be a low power mode in which at least one channel, but fewer than all channels of the touch screen are monitored. When is determined that a touch event has occurred a switch to a scan mode for touchscreen operation may be performed. Scan mode may be a higher power mode in which all channels of the touch screen are scanned at least for position sensing. The touch detect mode monitoring may be implemented by monitoring the total charge on the at least one channel and providing a voltage signal. When the voltage signal meets predetermined criteria an indication of a touch event may be generated.
