摘要： A display device includes; a panel, a timing controller generating an embedded clock data signal combining image data and a clock signal, and a column driver driving the panel in response to the embedded clock data signal. The data bits within the embedded clock data signal are communicated at one of three voltage levels in a three-level signaling scheme, and the timing controller determines one of the three voltage levels for a current data bit (DIN[n]) within the embedded clock data signal in relation to a voltage level of a previous data bit (DIN[n−1]) within the embedded clock data signal.

摘要： A current driver circuit includes a pull-down switch unit that is coupled between a node and a first reference potential and is operative to switch between an on-state and an off-state responsive to an input signal. A pull-up switch unit is coupled between the node and a second reference potential and is operative to switch between an on-state and an off-state, complementary to the pull-down switch unit. A turn-on speed of the pull-up switch unit is slower than that of the pull-down switch unit, and a turn-off speed of the pull-up switch unit is faster than that of the pull-down switch unit.
