Abstract
A display driving integrated circuit (IC) and a display driving method for supporting various driving mode include an input unit, a digital-analog converter and a row data output unit. The row data output unit outputs at least one of the row data to a row line corresponding thereto for each row scan clock pulse. The row data output unit activates output paths for outputting the row data to the row lines in an activation order of a driving mode selected from a plurality of driving modes having different orders of activating the output paths in response to a mode select signal.
Claims29
A display driver integrated circuit (IC) comprising:
- an input unit receiving digital video data to be displayed on a panel;
- a digital-analog converter converting the digital video data into analog row data and analog column data respectively scanned to row lines and column lines of the panel;
- and
- a row data output unit outputting at least one of the row data to a row line corresponding thereto for each row scan clock pulse,
- wherein the row data output unit activates output paths for outputting the row data to the row lines in an activation order of a driving mode selected from a plurality of driving modes having different orders of activating the output paths in response to a mode select signal.
A display driving method using a display driver integrated circuit (IC) comprising
