閣下的1000小時色偏烙印說法得拿出更明確數據比較好，
呃,我來幫忙說一下,那位S君講的1000小時的確是有所本的,
(當然我的發言並不等於他的意見,我是就我所知道的來講)
之前有篇網文曾提到過這個數據,原文網址如下:
http://disp.cc/b/72-5adx
不過,文內所說的1000小時這個數字是指
"某日系品牌的電視用1000小時後,其OLED的藍色衰減10%以上".
(1)由於文內所附連結無法連到原始數據來源,
所以也不知道該日系品牌的電視到底是用誰生產的面板在哪一年實測的.
(2)之前也有板友說過,手機的螢幕和電視的螢幕在設計上有很多不同~
於是我就順便查了一下,維基百科裡的確提到:
One 2008 technical report on an OLED TV panel found that "After 1,000 hours the blue luminance degraded by 12%, the red by 7% and the green by 8%."[69] In particular, blue OLEDs historically have had a lifetime of around 14,000 hours to half original brightness (five years at 8 hours a day) when used for flat-panel displays.
在2008年一篇關於SONY的OLED TV的報導中也出現了相符合的內容:
According to DisplaySearch, a market-research firm for the display market, the Sony XEL-1 OLED TV only has a 5,000 hour lifespan when displaying a plain white image, and 17,000 hours when displaying the usual video visuals. DisplaySearch tested the TV set on a 1,000 hour run and discovered that the color blue degraded by 12 percent, red by 7 percent, and green by 8 percent. The supposed 30,000 hour lifespan would mean 3.5 years of longevity if the OLED TV were left on 24/7. However, based on DisplaySearch's findings, the Sony XEL-1 OLED TV could last just 1.9 years before losing half its original brightness.
也就是說,(1)至少可確定的是,在2008年時OLED TV真的是不太禁用~ (2)當藍色衰減12%的時候,紅和綠也衰減了7~8%呢,也就是說1000小時後藍色和紅/綠色衰減的差距是４％對吧,大家可以用繪圖軟體重新做一個差距4~5%的圖再來看一下OLED TV色偏的情況~
(如果還有其他相關資料也請板友幫忙補上吧~)
至於文中說藍色用700小時就衰退5%的資料來源連結也是連不上,
我自己重新查到了目前正確的連結網址如下:

由於三星的super AMOLED的確是採用UDC的green PHOLED,
所以UDC那張表之前在SAMMOBLIE一篇講S4螢幕的文章裡也曾被引用過,
故用於討論AMOLED上我想是OK的~
(用700小時這個數字換算一下,店頭展示機用幾個月便出現烙印,就不難理解了吧)
ANYWAY,實驗室測出來的數據,並不能直接和實際使用體驗劃上等號,是吧. ^_^
