Abstract
本发明公开了一种LED显示面板离子迁移状态监测方法，属于Mini LED / Micro LED显示可靠性监测技术领域。针对现有技术监测维度单一、未校正温度漂移、无量化分级标准，存在监测精度低、误判率高、难以精准指导像素补偿的缺陷，本发明采用电流‑电压‑温度多参数并行采集，结合滑动平均滤波实现数据降噪。通过温度补偿消除环境温度引发的正向电压漂移误差，计算表征像素老化程度的离子迁移指数IMI，并依据阈值将像素离子迁移状态划分为正常、轻度、中度、重度四级。本发明可有效剔除温度干扰，实现像素级老化精准量化评估，分级阈值可适配不同芯片工艺，通用性强，可为显示面板像素自适应补偿、老化预警及可靠性维护提供可靠依据。
