Display system and display device driver

A display system, comprising:

• a display device;
• a transmitting device which generates compressed data by performing a compression process on image data corresponding to a display image;
• and
• a driver which drives said display device in response to said compressed data received from said transmitting device,
• wherein said driver includes:
• a decompression circuit which generates decompressed data by decompressing said compressed data;
• a Frame Rate Control (FRC) circuit configured to perform an FRC process on said decompressed data to generate display data;
• and
• a drive circuit which drives said display device in response to said display data,
• wherein said transmitting device is configured to generate said compressed data by compressing said image data by using a selected compression method which is selected from a plurality of compression methods,
• wherein, for at least one compression method of said plurality of compression methods, said FRC process is performed on at least part of said compressed data,
• wherein, for another compression method of said plurality of compression methods, no FRC process is performed on said compression data,
• wherein no FRC process is performed in said FRC circuit on a part of said decompression data corresponding to said compressed data generated by said at least one compression method, said part of said decompression data corresponding to said at least part of said compressed data, and
• wherein said FRC process is performed on said decompressed data corresponding to said compressed data generated by said other compression method, in generating said display data.
