近日換了新螢幕以後
號稱不閃屏低藍光
但跟公司電腦螢幕比起來發現
眼睛竟然比較痠
爬文了之後發現
大部分的網友對於近年來的LCD
常有覺得眼睛酸 畫面太亮的問題
問題是買的都是不閃屏低藍光的螢幕
可是我發現這些螢幕可以調的最低亮度不夠低
在辦公室那台是用pwm調光的反而眼睛不會酸
一開始覺得好像不合理
可是發現會不會是因為pwm調光可以較容易調低亮度
反而現在DC調光的LCD
亮度經常不夠暗
是不是用DC調光要把LCD變暗,技術成本較高
如果是這樣子那什麼不閃屏低藍光根本只是噱頭而已
能夠暗度調的夠低才是好螢幕
像可以調很低的Eizo 也是用LED背光
但是可以調很低,但是價格上萬元
所以
1. 不閃屏是不是假議題
2. DC調光把螢幕變暗是不是成本技術很高
未來我覺得應該螢幕要強調
最低亮度可以調到多暗才準
