LED顯示屏刷新率多少時拍照沒有橫紋?

發布時間:2023-4-20 15:11:39

        LED顯示屏用手機或者其他設備拍攝時有時候會出現橫紋,原因是使用的LED顯示屏刷新率不足,拍照成像的瞬間某些LED顯示屏上的行沒有點亮,就產生了一系列的水波紋現象。




        一般只有刷新頻率大于2倍相機快門速度的情況拍攝,LED顯示屏才不會出現水波紋。

        在相機普遍1/2000秒的快門速度下,普通橫流驅動IC的近1000刷新率和雙鎖存驅動IC的1920Hz刷新率,都不足以規避水波紋,只有擁有3840Hz以上刷新率的高清高階PWM驅動IC,更能保障LED顯示屏拍照時不出現水波紋。
