Dark themes are becoming more and more popular. On some devices, they can even save battery power. It all depends on what type of display your device have—only devices with OLED displays can reap the power-saving benefits.
黑暗主題變得越來越流行。 在某些裝置上，它們甚至可以節省電池電量。 這完全取決于您的裝置所用的顯示器類型-隻有配備OLED顯示器的裝置才能獲得節電的好處。
僅具有OLED顯示屏的裝置 (Devices With OLED Displays Only)
You’ve probably heard of OLED displays, especially if you’ve been on the market for a new TV in the last year or so. OLED screens differ from LCD and LED displays typically found in electronics in that OLEDs don’t have a backlight layer: each pixel is individually illuminated. This makes the display thinner, but the main draw is that black pixels don’t get lit up at all.
您可能聽說過OLED顯示器 ，尤其是如果您在過去一年左右的時間裡一直在購買新電視。 OLED螢幕不同于電子産品中通常使用的LCD和LED顯示器，因為OLED沒有背光層：每個像素都單獨發光。 這樣可以使顯示器更薄，但是主要的吸引點是黑色像素根本不會被點亮。
The result is higher contrast in your favorite films, inky blacks throughout any interface, and battery savings when you’re using a dark theme on your laptop or cell phone.
當您在筆記本電腦或手機上使用深色主題時，可以提高您喜歡的電影的對比度，在任何界面上都呈現出漆黑的黑色，并節省電池。
當深色主題可以為筆記本電腦節省電池電量時 (When a Dark Theme Can Save Battery Power on Your Laptop)
OLED laptops are starting to appear, with some newer models just announced at CES 2019. There haven’t been any macOS or ChromeOS laptops with OLED screens, but there are a few Windows options. HP’s Spectre x360 15 is shipping with a 15-inch Samsung AMOLED display, while Lenovo is offering its Yoga C730 with an OLED panel. Surface fans will be out of luck—Microsoft hasn’t shipped an OLED screen on its laptops yet.
OLED筆記本電腦開始出現，一些新型号剛剛在CES 2019上宣布。 尚無配備OLED螢幕的macOS或ChromeOS筆記本電腦，但有一些Windows選項。 惠普的Spectre x360 15配備15英寸三星AMOLED顯示屏，而聯想則提供帶有OLED面闆的Yoga C730 。 Surface風扇将不走運-微軟尚未在其筆記本電腦上傳遞OLED螢幕。
Changing to Windows’ dark theme is easy, and that will darken all of the built-in applications at the same time. Microsoft Office lets you change to a dark theme, as do a lot of third-party apps. Microsoft Edge, Mozilla Firefox and Google Chrome all offer dark themes, but your favorite websites may or may not. Google’s official dark theme isn’t stable on Windows yet but will arrive in the next few months.
更改為Windows的深色主題很容易，這将使所有内置應用程式同時變暗。 Microsoft Office使您可以更改為深色主題 ，許多第三方應用程式也一樣。 Microsoft Edge ， Mozilla Firefox和Google Chrome都提供深色主題，但是您喜歡的網站可能會也可能不會。 Google的官方深色主題在Windows上尚不穩定，但将在未來幾個月内出現 。
You won’t get the battery savings benefits if your laptop isn’t using an OLED display, and you could find the dark theme may harm your battery life—in theory, at least. A dark theme could lead you to crank your laptop’s brightness to read text and see buttons in the interface, and the higher brightness would draw more power from the battery. This will depend on how much light is in your environment, how well your eyesight works, and how efficient the backlight is—so you may not notice any difference. Just keep that in mind when you’re switching to the dark side.
如果您的筆記本電腦不使用OLED顯示屏，您将無法獲得節電的好處，并且您會發現深色主題可能會損害電池壽命-至少在理論上是這樣。 較暗的主題可能會導緻您提高筆記本電腦的亮度，以閱讀文本并檢視界面中的按鈕，而更高的亮度會從電池擷取更多電量。 這将取決于您的環境中有多少光，視力如何運作以及背光的效率如何，是以您可能不會注意到任何差異。 切換到陰暗面時，請記住這一點。
Of course, if you’re looking to save battery power, there are plenty of ways to increase your Windows laptop’s battery life. You could even use Windows 10’s battery saver mode. We’ve covered a lot of tips for saving battery power on your MacBook, too. And the same basic principles apply to extending your Chromebook’s battery life, too.
當然，如果您要節省電池電量，可以使用多種方法來延長Windows筆記本電腦的電池壽命 。 您甚至可以使用Windows 10的省電模式 。 我們也介紹了許多有關在MacBook上節省電池電量的提示。 同樣的基本原理也适用于延長Chromebook的電池壽命 。
當黑暗主題可以節省手機的電池電量時 (When a Dark Theme Can Save Battery Power on Your Cell Phone)
OLED displays are much more common in smartphones because they’re easier to produce in smaller sizes. Samsung’s Galaxy flagships have always used OLED screens, while iPhones reserve them for the iPhone X, XS, and XS Max—not the iPhone XR or any older iPhones. Google has been using OLED displays for its Pixel phones since 2016, while support from other manufacturers is hit and miss.
OLED顯示器在智能手機中更為常見，因為它們更易于以較小的尺寸生産。 三星的Galaxy旗艦店一直使用OLED螢幕，而iPhone則将它們保留給iPhone X，XS和XS Max使用，而不是iPhone XR或任何舊版iPhone。 自2016年以來，Google就一直在其Pixel手機上使用OLED顯示屏，而其他制造商的支援卻屢見不鮮。
Samsung offers a dark theme for its phone, while Pixel phones will receive a dark mode later this year with Android Q. Apple’s iOS 13 is also rumored to include a dark theme, but we won’t know that for sure until WWDC in late May or early June.
三星為其手機提供了深色主題 ，而Pixel手機将于今年晚些時候通過Android Q進入深色模式。 也有傳言稱蘋果的iOS 13包含一個黑暗的主題，但是直到五月下旬或六月初的WWDC之前，我們都無法确定。
Battery savings from using a dark theme with OLED screens are drastic: Google saw battery life savings between 15% and 60% when it moved from YouTube’s default white background to the dark mode. I spend a good portion of my day on Facebook Messenger to chat with friends and book musical performances, and Facebook just rolled out a dark theme to Messenger. I’ve noticed an extra percent or two on my phone at the end of the day, but that small amount could go a long way if I’m ever away from a charger. Doubletwist (my music player of choice) also offers a black theme, so most of my phone usage is spent in the dark, and I get the most of my phone’s battery.
通過在OLED螢幕上使用深色主題，可以節省電池電量 ：當Google從YouTube的預設白色背景切換到深色模式時， Google可以節省 15％到60％的電池壽命 。 我大部分時間都在Facebook Messenger上聊天，與朋友聊天并預定音樂表演，而Facebook剛剛向Messenger推出了一個黑暗的主題。 我注意到一天結束時手機上會多出一兩個百分點，但是如果我不帶充電器的話，這筆小數目可能會走很長一段路。 Doubletwist (我選擇的音樂播放器)也提供了黑色主題，是以我大部分的手機使用時間都是在黑暗中消耗的，并且我會充分利用手機的電池。
Don’t fret if your phone doesn’t have an OLED screen. Whether you’re on Android or using an iPhone, there are plenty of other ways to save battery life.
如果您的手機沒有OLED螢幕，請不要擔心。 無論您是使用Android還是使用iPhone ，還有許多其他方法可以節省電池壽命。
有些電視也使用OLED面闆 (Some TVs Use OLED Panels, Too)
LG LG
You don’t need to worry about battery life on your TV—and most of the time it will be displaying TV shows, movies, or video games, anyway. But, if you have an OLED TV, it will use less power when displaying blacks than bright colors.
您無需擔心電視上的電池壽命，并且在大多數情況下，無論如何它都會顯示電視節目，電影或視訊遊戲。 但是，如果您有一台OLED電視 ，則在顯示黑色時所用的功率要比明亮的顔色要少。
In theory, maybe you’ll save a few pennies on your electric bill if it spends a lot of time powered on and showing menus. LG makes some of the best OLED TVs, and those TVs also offer a dark theme in their user interfaces.
從理論上講，如果您花費大量時間打開電源并顯示菜單，則可能會節省電費幾美分。 LG制造了一些最好的OLED電視，這些電視的使用者界面也提供了深色主題。
