  • Patent number: 9953591
    Abstract: Systems, apparatuses, and methods for driving a split display with multiple display pipelines. Frames for driving a display are logically divided into portions, a first display pipeline drives a first portion of the display, and a second display pipeline drives a second portion of the display. Each display pipeline generates dither noise for each frame in its entirety but only utilizes dither noise for the portion of the frame which is being driven to its respective portion of the display. This approach prevents visual artifacts from appearing at the dividing line between the first and second portions of the display.

  • Patent number: 9830871
    Abstract: A method for driving a display panel having a variable refresh rate is disclosed. The method comprises detecting a condition that results in a charge accumulation in the display panel using an accumulated difference in time duration between frames of positive polarity and frames of negative polarity received from an image source. The DC imbalance is a result of a frame pattern comprising alternating frames of differing polarities, wherein frames of positive polarity within the frame pattern are of a different time duration than frames of negative polarity, and wherein the frame pattern results in an accumulation of charge in pixels of the display panel. The method also comprises correcting for the charge accumulation by disrupting the frame pattern.
