Abstract:
A display driver is provided. The display driver includes a compressor outputting first data by compressing input data, a first selection circuit transmitting the input data or the first data to a memory in response to a first selection signal, a de-compressor outputting third data by de-compressing second data output from the memory, and a display interface for transmitting fourth data generated by processing the third data to a display.
