Abstract: An electronic device includes a display panel with pixels arranged in at least one row and at least one column. The electronic device also includes a sensing channel coupled to the at least one column. The sensing channel indirectly calculates a threshold voltage of the plurality of pixels based on an application of a first current level and a second current level to a data line of a first column of the at least one column of the pixels.

Abstract: A display device may include a plurality of pixels that may display image data on a display. The display device may also include a circuit that may receive pixel data including a gray level for at least one pixel of the plurality of pixels. The circuit may then receive an emission clock signal using a clock circuit based on the pixel data, such that the emission clock signal may cause the at least one pixel to receive a current for an amount of time based on the gray level. The circuit may then gate off the clock circuit after the amount of time.

Abstract: An electronic device includes one or more unit pixels and threshold voltage (Vth) sensing circuitry. The threshold voltage sensing circuitry senses Vth of the one or more unit pixels, by: sampling a charge of a capacitor of the one or more unit pixels, transitioning from the sampling, and reading out the threshold voltage based upon a change in the charge of the capacitor, such that an operation of the one or more unit pixels may be modified based upon the threshold voltage.

Abstract: An electronic display includes an active area including multiple pixels. The electronic display also includes a first row driver set including a first column of row drivers and a second column of row drivers. A first active row driver in the first column of row drivers drives a first portion of the multiple pixels, and a first spare row driver in the second column of row drivers is in an inactive state. The electronic display also includes a second row driver set including a third column of row drivers and a fourth column of row drivers. A third active row driver in the third column of row drivers drives a second portion of the multiple pixels, and a second spare row driver in the fourth column of row drivers is inactive.

Abstract: A display may include an array of pixels covered by lenticular lenses. The lenticular lenses may cause expansion of light primarily in a horizontal direction. To improve the perceived resolution of the display, the horizontal resolution of the pixels on the display may be increased. In one possible layout, each pixel includes one red sub-pixel, one blue sub-pixel, and one green sub-pixel. The sub-pixels may be non-square rectangular. The sub-pixels may be the same size or may have the same widths and different heights. Each pixel may be asymmetric about a horizontal axis. In a given row, the pixels may alternate between first and second layouts. The second layout may be a vertically flipped version of the first layout.

Abstract: An electronic device may include a display. The display includes display driver circuitry for driving data lines routed across the display. The electronic device may have a recessed device housing region, where at least some of the data lines are routed around the recessed region. The data lines being routed around the recessed region may be formed in at least two different metal routing layers. The electronic device may further include additional display driver circuitry for driving data lines from another peripheral housing edge to obviate the need to route around the recessed region. The data lines from the two display driver circuitries can be disconnected at random locations or can be interlaced to achieve spatial interleaving. The display driver circuitry may include demultiplexing circuitry having smaller switches coupled in parallel with larger demultiplexer routing switches to reduce voltage kick and charge injection.

Abstract: A device may include image processing circuitry that generates image data corresponding to an image to be displayed during a first image frame and a second image frame. However, the image data is not regenerated for the second image frame. The device may also include an electronic display having a frame buffer that receives and stores the image data from the image processing circuitry. The electronic display may also include a display panel that displays the image during the first image frame based on a first read of the image data from the frame buffer in response to a first emission sync signal and displays the image during the second image frame based on a second read of the image data from the frame buffer in response to a second emission sync signal.
