1. A display driving chip, comprising:
a gaze tracker, an image receiver, an image parser and an image driver, wherein:
the gaze tracker is configured to perform real-time locating for a pupil center of human eyes and real-time calculation for gaze point coordinates, and output the gaze point coordinates of human eyes to the image parser;
the image receiver is configured to receive image data to be played through a first image interface and input the image data to be played to the image parser;
the image parser is configured to compress or decompress the image data to be played according to the gaze point coordinates of human eyes, and output compressed image data or decompressed image data to the image driver; and
the image driver is configured to receive the image data output by the image parser, control a connected display panel and drive the display panel to display in real-time according to a compression pattern of the image data and the coordinates of the gaze point,
wherein the image parser is configured to
detect whether the compressed image data needs to be decompressed when the image data to be played is compressed image data, and if so, decompress the compressed image data according to the gaze point coordinates of human eyes and output the decompressed image data to the image driver; if not, output compressed image data to the image driver; and
when the image data to be played is an original image data, store the original image data into a first cache region, read the data of the first cache region, compress the read data according to the gaze point coordinates of human eyes, and output to the image driver.
