Method and apparatus for transmitting image data

A controller, wherein the controller is connected to at least one driver chip in a display apparatus;

• and the controller comprises:
• a processor;
• and
• a memory configured to store one or more instructions executable by the processor;
• wherein the processor, when loading and executing the one or more instructions, is caused to perform a method for transmitting image data wherein the method comprises:
• acquiring initial image data of a to-be-displayed image in a display panel, wherein the display panel comprises a plurality of pixels, and the initial image data comprises pixel data of the plurality of pixels;
• compressing pixel data of a plurality of first pixels in the initial image data to acquire at least one piece of compressed pixel data, wherein the plurality of first pixels are disposed in a non-foveal region of the display panel, and a plurality of second pixels in the plurality of pixels other than the plurality of first pixels are disposed in a foveal region of the display panel, wherein the non-foveal region comprises a first region, wherein the first region and the foveal region of the display panel are arranged in a pixel column direction;
• pixels connected to the target driver chip comprise the first pixels and the second pixels, wherein the first pixels and the second pixels are sequentially arranged in a driving direction of a pixel row;
• and
• sending a power consumption reduction instruction to a target driver chip, the power consumption reduction instruction being configured to instruct the target driver chip to close a target channel, wherein the target driver chip is a driver chip for driving the first pixels and is provided with a plurality of data channels, and the target channel is a channel for receiving the compressed pixel data;
• sending the compressed pixel data to the target driver chip, wherein the compressed image data comprises the at least one piece of compressed pixel data and pixel data of the plurality of second pixels, and the compressed image data is configured for driving the display panel to display by the driver chip;
• sending a power consumption recovery instruction to the target driver chip, the power consumption recovery instruction being configured to instruct the target driver chip to open the target channel;
• and
• sending the pixel data of the second pixels connected to the target driver chip to the target driver chip;
• wherein an interval duration between sending the power consumption recovery instruction to the target driver chip and sending the pixel data of the second pixels is greater than or equal to a duration threshold, wherein the duration threshold is determined based on an open duration required for the target driver chip to open a data channel thereof, and the open duration is related to hardware parameters of the target driver chip.
