Patent number: 11929024Abstract: The organic light emitting display device is driven to be divided into a refresh frame when the data voltage is programmed in the pixel and a reset frame when the anode electrode of the organic light emitting diode is reset, and the data voltage is maintained to a first level during the reset frame. Accordingly, a separate stage for applying an on bias stress is not provided so that the bezel may be reduced.Type: GrantFiled: November 29, 2021Date of Patent: March 12, 2024Assignee: LG Display Co., Ltd.Inventors: Minsu Kim, Wonkeun Park, Haejun Park, Jieun Kang, Youngtaek Hong
