Abstract
一种有机发光二极管显示面板及其感测方法、驱动方法,该有机发光二极管显示面板(100)包括多个阵列排布的像素单元(11),每个像素单元(11)包括多个子像素(12),至少两个子像素(12)连接到同一条感测信号线(Se)。该感测方法包括:向有机发光二极管显示面板(100)中的子像素(12)依次施加感测数据信号,并通过感测信号线(Se)依次输出感测信号,以对子像素(12)进行感测,从而用于进行子像素补偿。在连接到同一条感测信号线(Se)的子像素(12)中,除被感测的子像素(12)之外的子像素(12)被施加零灰阶数据信号。该感测方法可以在减少感测信号线、提高像素开口率的同时,实现全屏子像素的感测,能够提高感测效率和感测稳定性。
