A display panel subsystem adaptively employs one of three types of input offset voltage cancellation modes based on an analysis of gray level values of sub-pixels for each row un a frame of image data. The system selects a candidate row within a selected group of rows and applies a first chopper mode to each sub-pixel in the candidate row. Under a row-based mode, the system applies a second chopper mode to each sub-pixel included in a row having gray level values matching the candidate row. Under a per-column row-based mode, the system applies the row-based mode on a per-column basis. Under a sub-pixel-wise mode, for each column, the system changes a chopper mode applied to a sub-pixel in a subsequent row relative to the last state of the chopper mode in a row having the same gray level value as a corresponding sub-pixel in the subsequent row.

An information handling system includes a timing controller configured to transmit a command for a common voltage of a particular frame rate to a power management circuit. A storage component may store digital information, wherein each digital information is associated with the common voltage of a particular frame rate. The power management circuit supports a variety of common voltage requirements of the liquid crystal display including an ability to select digital information of the digital information that is associated with the common voltage at the particular frame rate stored in the storage component and apply the common voltage at the particular frame rate to the liquid crystal display.

This application relates to systems, methods, and apparatus for optimizing the operations of a power converter of a display panel based on image data to be output by the display panel. The power converter can include one or more switches that can be activated or deactivated based on the image data in order to shift a power efficiency of the power converter. Power efficiency is shifted as a result of balancing an amount of charge necessary for a load with an amount of resistance created when activating switches of the power converter. Therefore, by dynamically altering a configuration of a power converter based on image data, power efficiency of the power converter can be improved.

In a data processing system that includes a graphics processor and a video processor, graphics textures for use by the graphics processor are stored as encoded frames of video data. The video processor then decodes the video frames to reproduce the graphics texture(s) that the video frames encode, and stores the decoded graphics texture or textures in memory for use by the graphics processor.

The graphics processor then reads the decoded graphics textures for use when generating its render outputs, such as output frames for display.

Methods and systems are described for determining an image resource allocation for displaying content within a display area. An image or data capture device associated with a display device may capture an image of a space associated with the user or capture data related to other objects in the space. The viewing distance between the user and the display area (e.g., the display device) may be monitored and processed to determine and/or adjust the image resource allocation for content displayed within the display area. Prioritization data associated with the content may be used to determine and/or adjust the image resource allocation for content displayed within the display area.

In general, aspects disclosed herein provide techniques for processing video data. Certain aspects provide a method for processing video data comprising a plurality of frames for display on a display as discussed herein. The method includes determining a sampling rate (N) based on a frame rate used for displaying the video data on the display. The sampling rate N is greater than 1. The method further includes, for every N frames of the plurality of frames, processing one or more statistics associated with a frame determine one or more display settings. The method further includes outputting to the display the corresponding N frames of the plurality of frames using the one or more display settings.

A head-mounted display device including first and second display surfaces associated with first and second eyes of the user, a graphics processing unit, one or more hardware processors, and an adaptive rendering module.
