    IPC: G09G3/3291

    Abstract: Techniques for implementing and/or operating an electronic device, which includes a display pixel that emits light to facilitate displaying an image during an emission period and a data driver coupled to the display pixel via a data line. The data driver generates a data line voltage signal based on image data that indicates target luminance of the display pixel in the image and supplies the data line voltage signal to the data line during a non-emission period preceding the emission period to facilitate writing the image to the display pixel. Additionally, the data driver supplies an intermediate voltage greater than a ground voltage to the data line during the emission period in which the image is displayed to facilitate reducing luminance variation in the image resulting from a leakage current flowing between an internal node of the display pixel and the data line during the emission period.

    Abstract: Systems and methods for improving perceived image quality of an electronic display, which includes a co-located sub-pixel that controls luminance of a first color component and an offset sub-pixel that controls luminance of a second color component. A display pipeline communicatively coupled to the electronic display determines image data, which indicates target luminance of the first, the second, and a third color component at an image pixel; determines edge parameters, which indicate whether an edge is expected to be present at the offset sub-pixel, based on a difference metric between a first image pixel block around the offset sub-pixel and a second image pixel block offset from the first image pixel block; and determines offset sub-pixel image data by filtering an image pixel group around the offset sub-pixel based at least in part on the edge parameters, wherein the offset sub-pixel image data indicates target luminance of the offset sub-pixel.

    Abstract: Driving methods and display systems are described for operating a display panel in flash mode. In an embodiment, the driving method includes time multiplexing between at least two panel operation voltage (VOP) levels including a first VOP level and a second VOP level across all Vdd input lines to a display area, and emitting a first wavelength range from a first subpixel group during application of the first VOP level across all of the Vdd input lines and emitting a second wavelength range from a second subpixel group during application of the second VOP level across all of the Vdd input lines.
