Publication number: 20220307435Abstract: Proposed is a method and system for controlling an Exhaust Gas Recirculation (EGR) device in high-load driving, and an internal combustion engine vehicle including the system. The method of controlling an EGR device in high-load driving compares a ratio of pressures at a front end and a rear end of a throttle valve with a preset critical value that is a reference for determining high-load driving, performs Wide Open Throttle (WOT) control for fully opening the throttle valve when the ratio of pressures is larger than the preset critical value, determines whether engine torque due to the WOT control and use of EGR satisfies torque requested by a driver, and corrects throttle opening or stops use of EGR, depending on whether the engine torque due to use of EGR together with the WOT control satisfies the requested torque.Type: ApplicationFiled: March 29, 2022Publication date: September 29, 2022Inventor: Ju-Hyun Park

Patent number: 10950185Abstract: An organic light-emitting display (OLED) device includes an image display member, an aging display member, a degradation compensation control member for compensating for degradation of original image data of display pixels of the image display member. Aging pixels of the aging display member are degraded by reflecting image driving data of the display pixels, and the degradation of the original image data is compensated depending on degradation confirmation values of standard cumulative stress indexes corresponding to cumulative stress of the display pixels. The degree of degradation of the pixels may be accurately reflected while having a high aperture ratio, so that effective degradation compensation may be performed.Type: GrantFiled: March 23, 2020Date of Patent: March 16, 2021Assignee: TLI INC.Inventors: Jae Gan Ko, Ju Hyun Park
