Publication number: 20230073431Abstract: High resolution displays, such as OLED displays, utilize complex driving circuits that can suffer from crosstalk. The crosstalk can affect the brightness of pixels in a row the display, which can be observed by a viewer as a crosstalk artifact. The severity of a crosstalk artifact may correspond to a contrast ratio of a high-contrast transition in which vertically adjacent pixels are sequentially driven by different driving signals during a scan. When a contrast ratio is above a maximum-perceptible contrast ratio, reducing the contrast ratio to the maximum-perceptible contrast ratio and can reduce, or eliminate, crosstalk artifacts. Disclosed herein are methods and devices that adjust pixels to reduce a crosstalk artifact without having a noticeable effect on contrast.Type: ApplicationFiled: February 7, 2020Publication date: March 9, 2023Inventors: Yenyu Peng, Chao-Ching Hsu, Wei-Chier Liao, Hsi-Chieh Peng
