Abstract: A digital-to-analog converter may include a converting unit and a distributing unit. The converting unit may generate a first analog signal set based on less-than-all bits of an image data set in a first period and may generate a second analog signal set based on all bits of the image data set in a second period. The all bits may include at least 2 bits. The distributing unit may include output terminals, may distribute the first analog signal set to the output terminals in a first sequence in the first period, and may distribute the second analog signal to the output terminals in a second sequence. The second sequence may be opposite to the first sequence.

Abstract: According to an embodiment, the display device includes a touch controller, an image processor, and a display driver. The touch controller is configured to output touch event information corresponding to a touch signal received from a touch panel. The image processor is configured to determine whether a host is in a sleep mode or a normal mode, and to output mixed image data obtained by overlapping an image displayed on a display panel and a marker corresponding to the touch event information while a host is in the sleep mode. The display driver is configured to output pixel driving signals corresponding to the mixed image data to the display panel. The touch controller or image processor is further configured to determine whether a touch input of a user to the touch panel meets a predetermined condition, and if the predetermined condition is met, output a wake-up signal to the host.
