    Abstract: A display device may include a pixel, an emission control driver, and a timing controller. The emission control driver may supply an emission control signal set for controlling emission periods of the pixel. The timing controller may receive a received bit stream that includes a first bit set and a second bit set, may determine a first duty ratio of the emission control signal set using bits of the first bit set without using any bit of the second bit set. The first bit set may include at least two bits. The second bit set may include at least one bit. The emission control signal set may control the pixel to operate according to the first duty ratio for each frame of a first frame group.

    Abstract: A method for determining whether or not a display panel is a duplicate is provided. The method includes: generating, by a code generator in an electronic module, a code, the electronic module including a plurality of electronic components; transmitting, by the code generator, the code to each of a first sequence generator in the electronic module and a second sequence generator in a display panel, the display panel being configured to be mounted to the electronic module; generating, by the first sequence generator, a first response value, and transmitting the first response value to a certification component in the electronic module; generating, by the second sequence generator, a second response value, and transmitting the second response value to the certification component; and comparing, by the certification component, the received first response value and the received second response value.

    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.

    Abstract: A display device includes a display panel, a scan driver, a data compensator, and a data driver. The display panel includes a first area and a second area distinguished from each other along a scan direction. Each of the first and second areas include pixels. The scan driver is configured to sequentially provide scan signals to the display panel along the scan direction. The data compensator is configured to: detect a pattern in which a difference between adjacent grayscale values in image data is greater than a reference value; and generate compensated image data by compensating for grayscale values corresponding to the second area in the image data based on the pattern corresponding to the first area. The data driver is configured to: generate data signals based on the compensated image data; and provide the data signals to the display panel.
