A data processing system comprises encoding circuitry operable to encode arrays of data elements, decoding circuitry operable to decode encoded versions of arrays of data elements, and consumer circuitry operable to use arrays of data elements. Data indicative of a resolution that is to be used by the consumer circuitry for at least one region of the array of data elements is provided to the encoding circuitry, and the encoding circuitry uses the data indicative of the resolution that is to be used by the consumer circuitry to control the generation of the representation for representing at least one block that the array of data elements is divided into.

Systems and methods are disclosed for synchronizing a document markup modification across a plurality of devices. One method comprises subscribing to one or more events occurring in a first document markup application and receiving a notification indicating a modification to a document markup in the first document markup application. A markup object associated with the modified document markup may be extracted and translated to a cross-compatible markup object. The cross-compatible markup object is transmitted to a second document markup application to be rendered and displayed to a user.

A head-mounted display device including a processor and a display is provided. The processor is configured to: determine whether a display load of the head-mounted display device is higher than a preset load; when the display load is higher than the preset load, select at least one external device capable of making the display load lower than the preset load from a plurality of external devices; and, transmit a to-be-calculated information to at least one external device. The display is configured to: display a calculated information received from the at least one external device.

Two corresponding color patches are displayed on two image displays until adjusted by a viewer to match visually to a common color. Two sets of code values rendered on the two corresponding color patches on the two image displays are identified. Two sets of tristimulus values for the viewer are determined based on the two sets of code values rendered on the two corresponding color patches on the two image displays. The viewer's color matching function are generated based on the two sets of tristimulus values. The viewer's CMF is used in image rendering operations on a target image display.

A method of presenting visual information on a screen (306) involves defining a boundary (314) delineating a first region of the screen (which may be towards a centre of the screen) from a second region of the screen (which may be towards a periphery of the screen), displaying a first portion of the visual information in the first region of the screen at a first display quality, and displaying a second portion of the visual information in the second region of the screen at a second, lower, display quality. The method further involves blurring the visual information for display in at least a portion of the second region. The location of the boundary (314) may change over time, and may be based on where a user is looking, or is expected to be looking, or on the type of information being displayed or based on other parameters.

A device for driving a display panel includes a display driving integrated circuit (IC) configured to transmit image data to the display panel, a display control IC configured to receive compressed image data from a host and including a timing controller configured to control the display driving IC, and a non-volatile memory configured to transmit data to and receive data from the display control IC, and configured to store driving parameters necessary for operation of the display driving IC.

The embodiment of the disclosure discloses a method for processing data, a device for processing data, a system for processing data, a system controller and a mudure controller. The method includes: receiving input image data; storing the image data into a memory; reading target image data from the memory according to loaded area information of at least one output portal, wherein the output portal is electrically connected with a display screen, and the loaded area information of the output portal characterizes a target display area of the display screen; compressing the target image data to reduce the data volume of the target image data to meet a output bandwidth of the output portal to obtain compressed image data characterized by a plurality of image data packets; and outputting the compressed image data through the output portal.

The present disclosure relates to the field of display technology, and provides a display panel and a driving method thereof, a compensation data compression method and a compensation data decompression method. The display panel includes a data compression unit and a data decompression unit. The data compression unit is used to acquire a plurality of first compensation data and a common parameter, and compress each of the first compensation data into second compensation data according to a preset compression rule based on the first compensation data and the common parameter. The data decompression unit is used to acquire a plurality of second compensation data and the common parameter, and decompress each of the second compensation data into the first compensation data according to a preset decompression rule based on the second compensation data and the common parameter.

A video input interface receives input video data in a normal state. A control input interface receives character data for On Screen Display (OSD) in a setup state. An encoder encodes the character data and stores encoded compressed data in a memory in the setup state. A decoder receives an instruction signal designating the character data to be displayed, reads and decodes one piece of compressed data corresponding to the instruction signal from the memory, and reproduces the original character data in the normal state. A multiplexer superimposes character data on frame data and outputs the data.

An apparatus includes a graphics driver circuit and a graphics engine circuit. The graphics engine circuit is configured to determine graphics data to be output to a display and to render the graphics data to a buffer. The graphics driver circuit is configured to output the buffer to the display. The graphics engine circuit is further configured to, while the graphics driver circuit is outputting the first buffer to the display, encode the first graphics data into another buffer, and to signal the graphics driver circuit to output the other buffer to the display.
