Abstract
Disclosed is a display device and a driving method thereof, and a mobile terminal. The display device includes a display panel on which a plurality of data lines, a plurality of gate lines, and a plurality of pixels to which a pixel driving voltage is supplied are disposed, a display panel driving circuit configured to scan the plurality of pixels and write pixel data to the plurality of pixels during a refresh frame period of a refresh frame; and a power circuit configured to output a pixel driving voltage and decrease the pixel driving voltage in a skip frame period of a skip frame in which scanning of the plurality of pixels is skipped.
Claims20
A display device comprising:
- a display panel on which a plurality of data lines, a plurality of gate lines, and a plurality of pixels to which a pixel driving voltage is supplied are disposed;
- a display panel driving circuit configured to scan the plurality of pixels and write pixel data to the plurality of pixels during a refresh frame period of a refresh frame;
- and
- a power circuit configured to output the pixel driving voltage and lower the pixel driving voltage in a skip frame period of a skip frame in which scanning of the plurality of pixels is skipped.
A method of driving a display device comprising:
- supplying a pixel driving voltage to a plurality of pixels disposed on a display panel;
- scanning the plurality of pixels during a period of a refresh frame to write pixel data to the plurality pixels;
- maintaining a data voltage previously charged during a skip frame period of a skip frame;
- and
- decreasing the pixel driving voltage in the skip frame period of the skip frame.
A mobile terminal comprising:
- a display panel on which a plurality of data lines, a plurality of gate lines, and a plurality of pixels to which a pixel driving voltage is supplied are disposed;
- a driver integrated circuit (IC) configured to output the pixel driving voltage at a default voltage level during a refresh frame period of a refresh frame, scan the plurality of pixels, and output the pixel driving voltage at a low potential level lower than the default voltage level during a skip frame period of a skip frame and a period of a partial refresh frame;
- and
- a host system configured to provide pixel data of an input image, frame identification information, and digital brightness value information to the drive IC,
- wherein the frame identification information includes information indicating at least one of the refresh frame, the skip frame, and the partial refresh frame.
