Abstract: A display device has a timing controller and a microdriver. The timing controller receives multiple bit sequences of image data for multiple pixels of the display device. The timing controller also reorders the multiple bit sequences based on a significant bit position within the multiple bit sequences. Each of the multiple bit sequences corresponds to a respective individual pixel of the multiple pixels. The microdriver receives the reordered multiple bit sequences and drives the multiple pixels using the reordered plurality of bit sequences.

Abstract: Aspects of the subject technology relate to electronic device display circuitry and methods of operating the display. The display circuitry includes gate-in-panel (GIP) drivers for each pixel row of a pixel array, and mode selection circuitry coupled between two of the GIP drivers. The mode selection circuitry receives a select signal to switch the display between a full-screen mode of operation and a split-screen mode of operation. The mode selection circuitry allows the pixel rows to be operated in a butterfly driving mode that facilitates reduction of optical artifacts when displaying augmented-reality or virtual-reality content with a multi-function display such as a display of a smartphone or a tablet.

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: An electronic device includes a display having an active array and a reference array. The active array includes a pixel and the reference array includes a reference pixel. The electronic device also includes processing circuitry communicatively coupled to the display. The processing circuitry is configured to instruct the active array to drive the pixel based at least in part on a set of degradation ratios and gamma tap points for each brightness setting of the display based at least in part on a reconstructed current-voltage curve.
