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.

A method of facilitating an interactive rendering of a computer image at a remote computer includes: at a first time, obtaining first information of the image, including pixel information of the image at the first time; and, at a second time after the first time, obtaining second information of the image including pixel information of the image at the second time. Delta pixel information is generated by comparing the pixel information of the first information with the pixel information of the second information, to include one or more portions of the pixel information of the second information updated since the first information was obtained, and to exclude one or more portions of the pixel information of the second information unchanged since the first information was obtained. The method further includes: transmitting the delta pixel information in a lossless format to a front-end client to enable reconstruction of the second information.

A display driving device, a control method therefor, and a display apparatus. The control method comprises: a main processing chip generates a read-write synchronization signal when buffering received display data, and each secondary processing chip receives the read-write synchronization signal (S202); in response to the read-write synchronization signal, the main processing chip buffers the received display data of the current frame image to be displayed to the frame address of a corresponding memory, and performs reading and processing on the buffered display data of a previous frame image to be displayed and then transmits to a display panel, and in response to the read-write synchronization signal, each secondary processing chip synchronously buffers the received display data of the current frame image to be displayed to the frame address of the corresponding memory, and synchronously performs reading and processing on the buffered display data of the previous frame image to be displayed and then transmits to the display panel (S203). By means of the read-write synchronization signal, the main processing chip and all the secondary processing chips are controlled to control the storage and read operations of the memory, and thus, the present invention can avoid that the processing chips share the frame address of the memory, and further can avoid the problem of abnormal image display due to multiple asynchronous processing chips.
