    Abstract: Systems, devices, and techniques are provided for displaying graphical content by modulating an intensity of one or more emitted light beams while redirecting those emitted light beams along a scan path that includes multiple locations of a projection surface Timing information that specifies timing values associated with each of multiple locations on a projection surface of an optical element is received or generated. One or more light beams that each have a respective intensity are emitted, and redirected along a scan path that includes at least some of the multiple locations. During the redirection of the one or more emitted light beams, the respective intensity of each of the one or more emitted light beams is modulated in accordance with the timing information to display one or more pixels of an image at each of the at least some multiple locations.

    Abstract: Systems, devices, and methods for driving projectors are described. The actual area projected over by a laser projector for a given pixel may not exactly match a desired projection area for the pixel, especially at edge regions of an image. In the present systems, devices, and methods, projection data is provided for at least one image to be projected by a laser projector. The projection data can include sets of alternative data sections at edge regions of the at least one image, effectively increasing resolution for the edge regions of the image. Depending on a projection pattern being used by a laser projector at a given time, select alternative data sections can be projected which closely match the actual area covered by the projection pattern, improving image quality.

    IPC: G09G5/393

    Abstract: Systems, devices, and methods for generating, processing, assembling, and/or formatting data for display are described. Example display controllers are described in which image data is stored in a framebuffer, and a compositor selectively retrieves portions of the image data. At least one P-operator produces lines of intermediate P-operated data by performing at least one intra-line operation on the image data retrieved by the compositor, such as repeating or reordering pixels of the image data. A Q-operator produces a stream of pixel data by performing inter-line operations on the intermediate P-operated data, such as interpolating between lines of the P-operated data. A display is driven according to the stream of pixel data.
