Disclosed herein is a method of writing data to, and reading data from, one or more buffers. The method comprises: determining a write rate of writing data into a first buffer; determining a read rate of reading data from the first buffer; determining, using the write rate and the read rate, a portion of the first buffer; writing data into the portion of the first buffer; starting to read data from the first buffer when the writing of data to the portion of the first buffer has finished; and writing data into a remaining part of the first buffer, different from the portion of the first buffer. The portion of the first buffer is determined such that the reading of data from the first buffer does not overtake the writing of data into the first buffer.

This application provides an electronic device, to reduce a probability that a screen stalling phenomenon. A timing control unit sends one first pulse of a tearing effect signal every a first preset time T1. The timing control unit sends S second pulses of the tearing effect signal when a transceiver unit does not receive an N.sup.th frame of display data within a preset time. The processing unit receives the N.sup.th frame of display data in the (N+1).sup.th frame, and controls, based on the N.sup.th frame of display data, the display to display an N.sup.th frame of image.

A processing system comprises a first integrated circuit (IC) and a second IC. The first IC comprises first image processing circuitry, first display panel driver circuitry, and first communication circuitry. The first image processing circuitry is configured to generate a first overlay image by overlaying a first partial input image with a first image element based on first partial input image data representing the first partial input image and first image element data representing the first image element. The first display panel driver circuitry is configured to drive a display panel based on the first overlay image. The first communication circuitry is configured to output second image element data representing a second image element to the second IC.

A display device including a controller and a display panel. The controller receives original image data and output a display image signal. The display panel receives the display image signal and displays a display image corresponding to the display image signal. The controller includes an image shift controller and a memory. The image shift controller generates shifted image data by modulating the original image data to shift the display image sequentially along a preset shift path on the display panel. The memory stores a shift path value indicating a distance by which the display image has been shifted on the preset shift path. The image shift controller generates the display image signal by processing the shifted image data. When the display device is powered on, the image shift controller generates shifted image data corresponding to a shift path value stored in the memory.

Apparatus for data communications includes a host interface, which is configured to be connected to a bus of a host computer having a processor and a memory. Processing circuitry, which is coupled to the host interface, is configured to receive video data with respect to a sequence of pixels, the video data including data words of more than eight bits per pixel for at least one pixel component of the pixels, and to write the video data, via the host interface, to at least one buffer in the memory while justifying the video data in the memory so that the successive pixels in the sequence are byte-aligned in the at least one buffer.

Image data for a current image frame may be compensated for transient response variations due to variations in display panel temperatures at various positions of the display panel by performing pixel drive compensation. The pixel drive compensation may be performed based at least in part upon display panel temperatures at various portions of the display panel. In this way, drive compensation corresponding to various temperature variations in a display panel may be implemented.
