Abstract: Visibility of the metal mesh touch electrodes can be mitigated using one or more mitigation techniques. In some examples, the boundary between touch electrodes and/or the boundary between a touch electrode and a routing trace of another touch electrode and/or the boundary between two routing traces can be non-linear. In some examples, dummy cuts can be made within an area of a touch electrode region (e.g., while maintaining the same electrical potential for the touch electrode region). In some examples, notches can be made in the metal mesh. In some examples, the location of cuts and/or notches can be optimized to mitigate visibility of the metal mesh. In some examples, some or all of the visibility mitigations may be used in combination in a touch screen.

Abstract: A display device may include rows of pixels that displays image data on a display. The display device also includes a circuit that performs a progressive scan across the rows of pixels to display the image data using a plurality of pixels. The circuit may then supply test data to at least one pixel of a plurality of pixels that corresponds to a first row of the rows of pixels during the progressive scan, determine one or more sensitivity properties associated with the at least one pixel based on the performance of the at least one pixel when the test data is provided to the at least one pixel, and resume the progressive scan at the at least one pixel to display the image data for the at least one pixel and a remaining portion of the plurality of pixels in the first row and remaining rows of pixels.

Abstract: A display device may include rows of pixels that may display image data on a display and a circuit. The circuit may perform a progressive scan across the rows of pixels to display the image data using a plurality of pixels, supply test data to a pixel of plurality of pixels that corresponds to a first row of the rows of pixels during one frame of the progressive scan, and initiate a sensing period for determining one or more sensitivity properties associated with the pixel based on the performance of the pixel with respect to the test data in response to receiving a pulse of a first global signal. The circuit may then end the sensing period in response to receiving a second global signal and resume the progressive scan across the rows of pixels to display the image data after the sensing period ends.

Abstract: Aspects of the subject technology relate to display circuitry. The display circuitry includes gate-in-panel (GIP) control circuitry on opposing sides of a display pixel array. The GIP control circuitry can include scan drivers for each pixel row on both sides of that pixel row, the scan drivers on either side configured for enablement or disablement for single-sided reduced-power operations. The GIP control circuitry can include a single scan driver and a single emission controller for each pixel row, in which the scan driver and emission controller for each row are disposed on opposing sides of the row. The scan drivers for a first subset of the pixel rows can be interleaved with the emission controllers for a different subset of the pixel rows.
