  • Organic light-emitting diode display and operation method thereof
    Patent number: 10522091
    Abstract: An OLED display and an operation method thereof, which are capable of preventing malfunctions caused by the influence of external noise on an extended cable when a display panel is separated from a set part by a predetermined distance or longer, are discussed. The OLED display includes a timing controller embedded in the set part separated from the display module by a predetermined distance and configured to control a reset signal for cancelling a safety mode to be transmitted to the display module in order to prevent the safety mode from being abnormally maintained due to the influence of external noise on a cable used to connect the display module and the set part when the safety mode for displaying a black screen is executed, to thereby prevent the display from continuously executing the safety mode to consistently display the black screen.
