LG G6使用PWM,雖然頻率是2410
More than 500 Hz are generally not an issue, but there seem to be many users
with problems below 250 Hz. Beware, there are even reports from readers that
suffer from frequencies above 10k Hz.
BTW 三星的數字包括各旗艦機都在200,很黑,吃定一般消費者不懂,也顯示他們的用
料品質仍有很多黑幕沒被發現,會爆炸真的不意外
1000Hz就是一秒閃1000下的意思
我是不曉得G6這麼高的頻率 (2410,通常500以上眼睛就無感,所以英文原文說
"not an issue") 會不會刺激眼睛疲勞,只是我幾年前對PWM電腦螢幕的使用經驗
非常非常糟糕,不會想買PWM產品。
PS LG G4不使用PWM,使用上眼睛很舒服。
至於為何PWM傷害眼睛?

最近有人私信問我為什麼調低亮度之後還是感覺眼睛很容易疲勞,一問之下才知道原來他
把亮度調的過低,也驚覺我的文章其實有重大漏洞
文章的第一個步驟我教大家降低亮度,主要是為了降低藍光的量,但我忽略了 LED 背光
有閃爍的問題,引用這篇文章:
LED與CCFL做為背光的螢幕時,都有著過亮卻不容易調暗(Dimming)的問題,簡單的
PWM技術應用了人眼視覺暫留的原理,當螢幕高速閃爍時,人眼無法感覺出來,卻因為螢
幕發亮的時間縮短而讓人覺得螢幕變暗了。(原本是一直亮著,變閃爍後,整體光源就減
少了)
也就是說,如果你的螢幕亮度越低那麼螢幕的閃爍問題就越明顯,人眼的瞳孔會因應不同
的亮度放大縮小瞳孔,如果螢幕一直閃爍那人眼就會不斷改變瞳孔的大小,久而久之眼睛
就會感到疲勞,累積下來就會得病
如果亮度太低,螢幕的閃爍就會加強,瞳孔不斷放大縮小讓眼睛更疲勞
如果亮度太高,螢幕的藍光就會加強,黃斑部應付過量藍光也會更疲勞
那到底該怎麼辦?最有效的解決方法就是換螢幕,推薦一下國產品牌 BenQ 的護眼螢幕
但螢幕一用就是好幾年,不是說換就換的,這時候還是有其他解決方法
我的文章關於亮度的地方有說明螢幕的亮度大概等於室內燈光的亮度最剛好。
維持著這個標準,首先先把電腦的螢幕亮度調整到最高,這樣螢幕就不會靠著 PWM 調光
而閃爍螢幕,然後來到我文章調整色溫的地方看到這張圖

不過如果LG便宜大碗真的退出台灣市場,那鰻可惜的,只是G4死雞的經驗真的要好好觀望
