In one embodiment, a computing system may store, in a memory unit, a first array of pixel values to represent a scene as viewed along a first viewing direction. The first array of pixel values may correspond to a number of positions uniformly distributed in an angle space. The system may determine an angular displacement from the first viewing direction to a second viewing direction. The system may determine a second array of pixel values to represent the scene as viewed along the second viewing direction by: (1) shifting a portion of the first array of pixel values in the memory unit based on the angular displacement, or (2) reading a portion of the first array of pixel values from the memory unit using an address offset determined based on the angular displacement. The system may output the second array of pixel values to a display.

A graphics pipeline includes a cache having cache lines that are configured to store data used to process frames in a graphics pipeline. The graphics pipeline is implemented using a processor that processes frames for the graphics pipeline using data stored in the cache. The processor processes a first frame and writes back a dirty cache line from the cache to a memory concurrently with processing of the first frame. The dirty cache line is retained in the cache and marked as clean subsequent to being written back to the memory. In some cases, the processor generates a hint that indicates a priority for writing back the dirty cache line based on a read command occupancy at a system memory controller.

Video or graphics, received by a render engine within a graphics processing unit, may be segmented into a region of interest such as foreground and a region of less interest such as background. In other embodiments, an object of interest may be segmented from the rest of the depiction in a case of a video game or graphics processing workload. Each of the segmented portions of a frame may themselves make up a separate surface which is sent separately from the render engine to the display engine of a graphics processing unit. In one embodiment, the display engine combines the two surfaces and sends them over a display link to a display panel. The display controller in the display panel displays the combined frame. The combined frame is stored in a buffer and refreshed periodically. In accordance with another embodiment, video or graphics may be segmented by a render engine into regions of interest or objects of interest and objects not of interest and again each of the separate regions or objects may be transferred to the display engine as a separate surface. Then the display engine may transfer the separate surfaces to a display controller of a display panel over a display link. At the display panel, a separate frame buffer may be used for each of the separate surfaces.

A channel control unit and a display device using the same are provided. The channel control unit can include a data driver that converts pixel data into data voltages and supplies the data voltages to data lines, and an ineffective channel controller that receives channel data, generates dummy data during an ineffective channel section indicated by the channel data, and sends the dummy data to the data driver.

An electronic apparatus is provided. The electronic apparatus includes a display device, a sensor, and a processor. The display device receives an image data. The display device includes a display panel and displays an image related to the image data on the display panel. A reference image point of the image is displayed on a first location on the display panel. The sensor detects a movement status of the electronic apparatus when the electronic apparatus shakes to generate at least one movement parameter. The processor calculates compensation data according to the at least one movement parameter and size information of the display panel. When the display device receives the compensation data, the display device displays the image by shifting the reference image point of the image from the first location to a second location on the display panel to display according to the compensation data.

A data display method and device based on an ARM micro-controller, and a readable storage medium are provided. The data display method includes receiving data signals of a display image, and storing the data signals; extending the stored data signals into multiple data signal sets in a preset sequence, and synchronously caching the multiple data signal sets in a rising edge and a falling edge of a clock signal; and controlling the multiple data signal sets to be respectively output to multiple output ports to control a display unit to display the image.

The present disclosure provides a method and device for switching a display channel, a display driving device and a display device. The method includes: sending a first switching signal to a write controller of a current display channel when a switching instruction for switching from the current display channel to a target display channel is received; acquiring a frame address in which final write operation of data is completed, and taking the frame address as a first address and a next frame address as a second address; sending a second switching signal to a write controller of the target display channel; and sending a third switching signal to a read controller.

A mechanism is described for facilitating consolidated compression/de-compression of graphics data streams of varying types at computing devices. A method of embodiments, as described herein, includes generating a common sector cache relating to a graphics processor. The method may further include performing a consolidated compression of multiple types of graphics data streams associated with the graphics processor using the common sector cache.
