Abstract
A display apparatus is provided. The display apparatus includes: a liquid crystal panel; a source driver configured to output a grayscale voltage to the liquid crystal panel; a power supply configured to provide a voltage to the source driver; and a controller configured to control the power supply and the source driver to change a maximum voltage provided to the source driver and a grayscale voltage based on conversion of a screen mode, and to set a predetermined grayscale region and an over driving region within an entire grayscale region.
Claims16
A display apparatus comprising:
- a liquid crystal panel;
- a source driver configured to output a grayscale voltage to the liquid crystal panel;
- a power supply configured to provide a voltage to the source driver;
- and
- a controller configured to control the power supply and the source driver to change a maximum voltage provided to the source driver and a grayscale voltage based on conversion of a screen mode, and to set a predetermined grayscale region and an over driving region within an entire grayscale region.
A method of controlling a display apparatus including a liquid crystal panel, a source driver configured to output a grayscale voltage to the liquid crystal panel, and a power supply configured to provide a voltage to the source driver, the method comprising:
- controlling the power supply and the source driver to change a maximum voltage provided to the source driver and a grayscale voltage based on conversion of a screen mode;
- and
- setting a predetermined grayscale region and an over driving region within an entire grayscale region.
A non-transitory computer readable recording medium having embodied thereon a program, which when executed by a processor of a display apparatus including a liquid crystal panel, a source driver configured to output a grayscale voltage to the liquid crystal panel, and a power supply configured to provide a voltage to the source driver, controls the display apparatus to execute a method, the method including:
- controlling the power supply and the source driver to change a maximum voltage provided to the source driver and a grayscale voltage based on conversion of a screen mode;
- and
- setting a predetermined grayscale region and an over driving region within an entire grayscale region.
