Abstract: A method and apparatus for overdriving pixel elements to a desired voltage. A display device comprises a pixel array and overdrive circuitry to determine a current pixel value for a first pixel element of the pixel array and a target pixel value for the first pixel element. The overdrive circuitry is further configured to determine a first voltage to be applied to the first pixel element to cause the first pixel element to transition from the current pixel value to the target pixel value by a first instance of time. The first voltage is determined based at least in part on a position of the first pixel element in the pixel array. The display device further comprises a data driver to apply the first voltage to the first pixel element before the first instance of time and a backlight to illuminate the pixel array at the first instance of time.

Abstract: A display and touch driver architecture is described that includes a plurality of source drivers and a processing system. The processing system operates receivers within the source drivers to selectively receive sensing data from the receivers and determines positional information based on the sensing data. The processing system may selectively operate different source drivers in low power modes and/or for capacitive sensing based on the determined positional information.

Abstract: A display device, a processing system, and a method are provided for updating a display device using self-refresh techniques. The described technique provides an indication to a host processor of whether a frame of display update data has been successfully compressed and stored entirely within a local frame buffer of the display. The host processor may invoke a self-refresh of the display for updating the display with a static display image, based on the received indications.

Abstract: A capacitive sensing device detects the presence of an actively modulated input object, such as an active pen, using a matrix of sensor electrodes. The capacitive sensing device include receiver channels configured to perform capacitive sensing of the active pen based on one frequency, and other receiver channels configured to perform capacitive sensing of other input objects based on another frequency. The receiver channels for sensing the active pen may be multiplexed across the matrix of sensor electrodes to track the location of the active pen in a tracking window manner. The receiver channels for sensing the active pen may also be multiplexed across the matrix of sensor electrodes to broadly search for the location of the active pen.

Abstract: An electrode matrix that is used for capacitive sensing may be integrated into a display panel of an input device. In one embodiment, source drivers may be mounted on the display panel which drive the display signals and capacitive sensing signals into the display panel. In one embodiment, the capacitive sensing signals may be routed on traces or lines that are interleaved on the same layer as the source lines used for setting a voltage on the pixels in the display panel during display updating. Using the interleaved traces, the source drivers may drive the capacitive sensing signals in parallel to a plurality of the electrodes in the matrix in a predefined pattern that spans one or more sensing cycles.
