Abstract: A display device is disclosed that includes a pixel component configured to output an image based on a first driving frequency, a scan driver configured to sequentially provide a scan signal to each pixel row in each frame based on the first driving frequency, and a driving controller configured control the scan driver such that, in the case where image data includes data corresponding to a static image, a display area is divided into a first area for the static image, and a second area for a video, and the first area is driven at a second driving frequency, and the second area is driven at a third driving frequency. The driving controller may control the scan driver such that a driving frequency corresponding to the first area is reduced to the second driving frequency, and a driving frequency corresponding to the second area is increased to the third driving frequency.

Abstract: A source driver includes a digital-to-analog converter that converts signals corresponding to first and second colors included in digital image data into first and second analog color data voltages, respectively, an output buffer unit including a first output buffer that alternately outputs the first color data voltage and the second color data voltage during one horizontal period, and a controller that controls the digital-to-analog converter and the first output buffer to alternately output the first color data voltage and the second color data voltage corresponding to each horizontal period for each horizontal period. The controller controls the first output buffer such that the second color data voltage is output after the first color data voltage is first output during a first horizontal period, and the first color data voltage is output after the second color data voltage is first output during a subsequent second horizontal period.

Abstract: A method of storing data in a distributed manner based on data compression ratio prediction, and a mass storage device and system using the method are disclosed. The device includes a compression ratio predicting unit, a compressing unit, and a control unit. When an address and first unit sized data are received, the compression ratio predicting unit estimates the predicted compression ratio of the first unit sized data. The compressing unit generates compressed data. The control unit calculates the benefit of compression based on at least the estimated predicted compression ratio, stores the compressed data in a first storage area if the calculated benefit of compression is higher than a predetermined benefit threshold value, and stores the first unit sized data in the second storage area if the calculated benefit of compression is equal to or lower than the predetermined benefit threshold value.
