摘要

随着超高清显示器的普及,减轻 8K 液晶面板的水平串扰效应至关重要。高显示分辨率要求更窄的信号线集成度,从而加剧了耦合效应。传统的方法,如 Vcom 反馈和增加模拟电压漏极-漏极 (AVDD) 负载,速度较慢,精度较低,导致功耗增加。为此,我们提出了一种先进的数字信号补偿方法。在这项研究中,我们开发了一个预测模型,并研究了 AVDD、Vcom 和存储容量 (Cst) 纹波对水平串扰的复杂关系。通过改变补偿系数(a)和衰减比(τ)来优化纹波变化(ΔG),可显著降低串扰效应。数字补偿方法可实现无延迟的快速精确补偿,将 8K 液晶面板的水平串扰从 4% 降低到 0.9% 以下。这超过了将串扰降至 2% 以下的要求,大大提高了高分辨率显示器的图像质量。

Digital horizontal crosstalk compensation in 8K LCD displays for enhanced image quality

Digital horizontal crosstalk compensation in 8K LCD displays for enhanced image quality

As ultra-high-definition displays have gained popularity, mitigating the horizontal crosstalk effect in 8K LCD panels is crucial. High display resolution requires narrower signal line integration, intensifying the coupling effect. Traditional methods like Vcom feedback and increasing analog voltage drain-drain (AVDD) load are slower and less accurate, leading to increased power consumption. In response, we propose an advanced digital signal compensation method. In this study, we developed a predictive model and investigated the intricate relationships among AVDD, Vcom, and storage capacity (Cst) ripples on horizontal crosstalk. Optimizing the ripple change (∆G) by varying the compensation coefficient (a) and decay ratio (τ) significantly reduces crosstalk effects. The digital compensation method allows rapid and precise compensation without delays, reducing horizontal crosstalk in 8K LCD panels from 4% to below 0.9%. This surpasses the requirement of minimizing crosstalk to less than 2%, substantially enhancing the image quality of high-resolution displays.
