Patent number: 10522091Abstract: 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.Type: GrantFiled: September 6, 2018Date of Patent: December 31, 2019Assignee: LG DISPLAY CO., LTD.Inventor: Oh-Jong Kwon

Patent number: 7551167Abstract: A shift register is provided, which adopts a shift operation delay for each memory device, or a data conversion control system through the estimation of conversion of data storage state. A driver circuit of LCD is provided, which adopts such a shift register, to thereby prevent instantaneous increase of electric power consumption while preventing EMI. Accordingly, shift registers operate as being sequentially delayed for each memory device or data conversion is minimized, thus preventing instantaneous excessive consumption of electric power.Type: GrantFiled: May 9, 2005Date of Patent: June 23, 2009Assignee: Samsung Electronics Co., Ltd.Inventors: Jin-Ho Park, Dong-Won Park, Oh-Jong Kwon
