Abstract: A touch screen having touch circuitry integrated into a display pixel stackup. The touch screen can include a transistor layer, an LED layer and a first layer. The first layer can operate as an LED cathode during a display phase and as touch circuitry during a touch sensing phase. The transistor layer can be at least partially utilized for transitioning between the display phase and the touch sensing phase. The touch screen can be fabricated to reduce or eliminate damage to the LED layer.

Abstract: A display device may include a plurality of rows of pixels configured to display image data on a display and a first gate driver circuit. The first gate driver circuit may couple a first voltage source to a first node associated with a first gate of a first switch upon receipt of a start signal or a gate signal from another gate driver circuit and couple a first clock signal to a first gate line via the first switch after a first voltage of the first node exceeds a threshold. The threshold is associated with activating the first switch, such that the first gate line is configured to couple to a first row of the plurality of rows of pixels. The first gate driver circuit may then couple a second voltage source to the first node based on a second clock signal, such that the second voltage source discharges the first node.

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.
