A display driver includes a video data conversion unit, a data compression unit, a memory unit, and a data restoration unit. The video data conversion unit converts first video data that includes RGB data to second video data that includes pentile data. The data compression unit compresses at least a portion of the second video data. The memory unit stores at least the compressed second video data. The data restoration unit restores the compressed second video data.

Display driver for pentile-type pixels and display device including the same

A pixel data compression device is provided. The device includes: a first judgment unit for comparing a number of bits of a value of first pixel data and a number of bits of a value of second pixel data with a number of reference bits; a format determination unit for determining a format of compressed data, the format corresponding to the number of bits of the value of the first pixel data and the number of bits of the value of the second pixel data; and a compression unit for generating the compressed data, which corresponds to the format of the compressed data, from the first pixel data and the second pixel data. The compressed data includes a flag region, a first data region, and a second data region.
