    Abstract: A foldable display device includes a display panel with a first display region, a second display region and a foldable display region located between the first and seconds display regions. A degradation information storage stores first degradation information for a first edge region and second degradation information for a second edge region. An edge information extractor extracts, in a first partial driving mode, first edge information for the first edge region from first partial image data, and extracts, in a second partial driving mode, second edge information for the second edge region from second partial image data. A gradation image generator generates, in the first partial driving mode, first gradation data based on the first edge information and the second degradation information, and generates, in the second partial driving mode, second gradation data based on the first degradation information and the second edge information.

    Abstract: 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.

    Abstract: A display device includes a display unit including a first pixel having a first color sub-pixel and a second color sub-pixel and a second pixel having a third color sub-pixel and another second color sub-pixel, an input gamma unit that converts first through third color grayscale data into first through third color luminance data, a buffer unit that stores the first through third color luminance data of a last pixel-column, a vertical rendering unit that increases the first and third color luminance data of the last pixel-column by using the first through third color luminance data of the last pixel-column as first and third color luminance data of an absent pixel-column adjacent to the last pixel-column, and an output gamma unit that converts the first through third color luminance data into the first and second color grayscale data or the third and second color grayscale data.
