有些電視節目比較舊了，只有4：3的畫面
螢幕兩邊會留黑邊，這樣看久了
會不會中間跟旁邊的顏色不同或烙印？

Much has been discussed regarding image retention on OLED TVs, however most of the discussion centers around bright static images encountered while playing video games or utilizing the TV as a computer monitor. The local Best Buy has an LG B6 OLED on display with severe permanent screen burn that, according to the sales rep, does not disappear after a correction cycle has run. Power is not removed from the set over night, so the normal compensation cycles should be running at shutdown. This TV has been running the same video demo loop for close to a year.
I am an old movie fan and 50% of my viewing consists of 4 x 3 pillarbox content. I realize that you can manipulate the aspect ratio settings to fill the screen, but I prefer to view such in their native format. I would also love to purchase an OLED for the perfect blacks they exhibit. Considering the high percentage of time vertical back bars are displayed during my usage, will this be a permanent image retention issue with OLED sets over time in your opinion?

我是一個老電影迷，50％的觀看由4:3的內容組成。我意識到您可以操縱寬高比設置來填充屏幕，但我更喜歡以原始比例查看。我也很樂意為他們展示的完美黑色購買一個OLED。考慮到在使用過程中顯示垂直黑條的時間比例很高，您認為OLED隨著時間的推移會永久烙印圖像？

回答是:
There is no image retention for black, because an OLED's pixels are off when showing black. After many years of frequently watching content with these black bars you may start to notice that the pixels in the black bars have aged less than in the center, so on normal content the center is dimmer than the sides; however this will probably only happen after decades of intensive use.
Permanent image retention is extremely rare in modern OLED TVs, and is usually covered under warranty if it does happen. Temporary image retention is common, but fades away after watching normal content for 15 minutes or so, because the picture is always changing during normal content.

黑色沒有圖像保留，因為顯示黑色時OLED的像素關閉。經過這些黑色條紋經常多次觀看內容後，您可能會開始注意到，黑色條紋中的像素年齡小於中央，因此正常內容中心比側面更暗; 然而，這可能只有經過數十年的密集使用才會發生。
永久烙印圖像在現代OLED電視機中極為罕見，如果發生這種現象，通常在保修範圍內。臨時圖像烙印是常見的，但在觀看正常內容15分鐘左右後會消失，因為圖片在正常內容中總是會發生變化。

接下來每個禮拜都會測量並公佈HDR峰值、色飽和度、畫面均勻、亮度...等等數值變化
OLED也會每週做一次清除雜訊的維護動作
樓主的顧慮若是成真，左上方那個100%不透明的黑色"T"就會有狀況
由專業獨立的第三方做長期OLED燒機測試，個人是非常期待～

在經歷4週560小時的燒機測試後，左上方100%不透明的常駐logo已造成OLED永久性烙印，
紫色背景下尤其明顯
Rtings編輯也在Q&A中證實永久性烙印的存在，
即便如此，Rtings編輯表示OLED迅速的反應速度依舊值得推薦給遊戲應用，
編輯表示OLED在耐用度上確實有其局限，但目前烙印在一般畫面下依舊算是相對輕微
畢竟很少有上百小時的常駐畫面出現在一般使用情況
燒機測試持續進行中...
