    Abstract: A display may be foveated to reduce power consumption and increase row scan timing margin. In one embodiment, the display includes pixels, where a first set of the pixels are formed to have a low resolution and a second set of the pixels are formed to have a high resolution. A first subset of the first set of pixels is formed in a first pixel cell layout and includes anodes formed in a first anode layout. A second subset of the second set of pixels is formed in a second pixel layout and includes anodes formed in a second anode layout. In another embodiment, the display similarly includes pixels formed to have a low resolution or a high resolution. The pixels of this embodiment may be formed in the same anode layout.

    Abstract: Embodiments relate to a display device having a display area with a plurality of rows of pixels. Multiple rows of the display area may be grouped such that data is written to the pixels of all rows of the grouping concurrently. Each row includes a respective gate scan driver circuit coupled to the gate line of the row, and to a gate scan line configured to sequentially provide an enable pulse to gate scan driver circuits of the plurality of rows over a plurality of time periods. The gate scan driver circuit selectively provides the enable pulse provided by the gate scan line or a gate enable signal of a gate line of an adjacent row as a gate enable signal to the gate line of the respective row, based upon a predetermined grouping of rows of the display device.

    Abstract: Embodiments relate to a foveated display, in which image data is displayed with a plurality of display regions associated with different image resolutions. The different resolutions are achieved using macropixels corresponding to groupings of native pixels of the display area onto which image data is loaded to concurrently. Macropixels spanning multiple columns of the display are constructed by grouping data lines of the display such that the same image data is written to pixels of different columns concurrently. The data lines receive image data from a signal line via a demultiplexer, where control signals of the demultiplexer to concurrently couple the signal line to multiple data lines, such that image data provided along the signal line is concurrently provided to each of the multiple data lines in parallel, based upon a predetermined grouping of columns of the display device.

    Abstract: Described is a system including a display, a display controller, and control logic communicatively coupled to the display. The display controller determines, based on coordinates of a focus point on the display, boundaries of a first image region and a second image region in an output image to be rendered. The focus point is determined through tracking an eye movement of a user viewing the display. The first image region has a higher resolution than the second image region. The display controller is configured to send image data together with control signals to the control logic. The control signals cause the control logic to render the output image on the display using the image data. As part of rendering the second image region, the control logic outputs a shared signal onto signal lines that are coupled to light sources in a group of adjacent rows or columns.
