摘要： The present disclosure relates to a data transmission and reception method of a data driving device and a data processing device as well as a data transmission and reception system, and more particularly, to a method and a system in which the data driving device receives an initial configuration value from the data processing device, stores the initial configuration value as a configuration restoration value, and rapidly restore an environment for a high-speed communication by using the stored configuration restoration value when a link between the data processing device and the data driving device is lost so as to reduce a time for restoration.

摘要： The present embodiment relates to a technology for driving a display device, and provides a technology in which a pixel driving device determines whether or not an overcurrent flows through a driving voltage line, and, if it is determined that an overcurrent flows therethrough, controls pixel data or an analog voltage output to a pixel so as to reduce a driving current.
