Abstract:
A display device includes pixels, a serial-to-parallel converter (SPC), a row driver, a column driver, and a switch. The pixels are arranged in rows and columns which include a first column and a first row. A first pixel resides at an intersection of the first row and first column. The SPC extracts, from a signal sent by a graphics controller, pixel data and a command. The row driver initiates a refresh of the pixels residing in the first row based on the pixel data. The column driver transmits the pixel data to the first column. During the refresh, the switch allows transmission of the pixel data to the first pixel when the command indicates that the first pixel is to be refreshed and prevents transmission of pixel data to the first pixel when the command indicates that the first pixel is not to be refreshed.
