Patent number: 10217397Abstract: In a method of operating a display apparatus, during a first period in which image data is provided to a data driver, a clock embedded data signal having an output differential voltage (“VOD”) set to a first voltage value is applied to the data driver. The VOD of the clock embedded data signal relates to a voltage difference between a high level and a low level of the clock embedded data signal. During a second period in which the image data is not provided to the data driver, the VOD of the clock embedded data signal applied to the data driver is changed to a second voltage value smaller than the first voltage value.Type: GrantFiled: April 17, 2017Date of Patent: February 26, 2019Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Ki-Seob Lee, Sangrock Yoon, Dongin Kim
