Patent number: 10140921Abstract: Various embodiments relate to an EM signal control circuit, an EM signal control method, and an organic light emitting display device. The EM signal control circuit according to an embodiment of the present invention includes additional elements (e.g., a transistor and a capacitor) configured to separate a set signal from a gate electrode of a transistor coupled to an output node and to stably keep turn-off of a transistor coupled to the output node. Voltage levels of a first emission power source and a first gate power source may be set differently from each other according to the present invention. Therefore, despite of a threshold voltage change of a transistor coupled to an output node, the transistor may remain turned off stably, thereby improving the reliability of the EM signal.Type: GrantFiled: December 12, 2016Date of Patent: November 27, 2018Assignee: LG DISPLAY CO., LTD.Inventors: Hyoung-Su Kim, Euitae Kim, KiSeob Shin, Yongmin Jeong
