Display driver with improved power consumption and operation method of improving power consumption of image data processing device

摘要

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.

1. A display driver comprising:
a compressor configured to output first data by compressing input data to reduce size of the input data; a first selection circuit configured to transmit the input data or the first data to a memory in response to a first selection signal; a de-compressor configured to output second data by de-compressing third data output from the memory to restore the third data; a display interface configured to process the second data and create fourth data for transmitting to a display; a second selection circuit configured to transmit the input data or the third data to the decompressor based on a second selection signal; a first pin configured to receive the first selection signal; and a second pin configured to receive the second selection signal.
