A source driver receives a horizontal synchronization signal of an image signal, and a binary control signal which varies in two values in synchronization with the horizontal synchronization signal and in which start values of adjacent frames of the image signal are different, excluding a vertical synchronization signal of the image signal, to apply a drive voltage to source signal lines of a display panel. In the source driver, the vertical cycle of the image signal is analyzed based on the binary control signal; a pseudo vertical synchronization signal is generated based on the vertical cycle; and a cancel operation of an offset voltage component of the drive voltage is performed based on the pseudo vertical synchronization signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Source driver for display panel and drive control method","description":"A source driver and drive control method that cancel offset voltages and enable quality display when a vertical synchronization signal is not fed to the source driver.
