The method includes, during a data refresh stage of at least one display frame, loading a gate turn-on voltage to a gate line, and loading, on each data line, a data voltage of an image to be displayed, so that each sub-pixel inputs a corresponding data voltage, and during a blanking time period, loading a gate turn-off voltage to a gate line, and loading a compensation voltage to each data line. When a data voltage in a sub-pixel connected to a data line is greater than a common electrode voltage, a compensation voltage is less than the data voltage in the sub-pixel connected to the data line, and/or when the data voltage in the sub-pixel is less than the common electrode voltage, the compensation voltage is greater than the data voltage in the sub-pixel.Type: ApplicationFiled: September 29, 2021Publication date: October 31, 2024Inventors: Yuhang TIAN, Yanping LIAO, Dongchuan CHEN, Shulin YAO, Yingmeng MIAO, Yinlong ZHANG, Pengfei HU, Wenpeng MA, Zheng ZHANG, Jiantao LIU

Patent number: 12115917Abstract: A method for estimating a trailer wheel position includes identifying a first set of wheel locations in a first image. Each of the wheel locations in the first set of wheel locations is associated with a corresponding trailer angle. The first set of wheel locations is clustered and a primary cluster in the first set of wheel locations is identified. A best fit curve is applied to the primary cluster. The best fit curve is a curve associating wheel position to trailer angle. An estimated wheel position is determined by applying a determined trailer angle to the best fit curve in response to the wheel being hidden in the first image. The estimated wheel position is output to at least one additional vehicle system.Type: GrantFiled: December 13, 2022Date of Patent: October 15, 2024Assignee: Stoneridge Electronics ABInventors: Wenpeng Wei, Liang Ma, Yifan Men, Troy Otis Cooprider
