AMOLED是一种在许多屏幕上使用的显示技术(display technology)。它们中的大多数通常都可以在智能手机上找到，因此，如果您一直在寻找三星或 Google Pixel(Samsung or Google Pixel)等品牌的智能手机，您可能会偶然发现一些吹嘘拥有AMOLED显示屏的产品。你知道AMOLED代表什么，它是什么吗？如果您想知道答案并了解为什么AMOLED既好又坏，请继续阅读：
AMOLED屏幕是什么意思？
AMOLED是一种OLED 显示器，是(OLED display)Active Matrix Organic Light Emitting Diodes的首字母缩写。OLED部分(OLED part)是指显示器使用LED(LEDs)和由碳等物质制成的有机化合物来点亮和显示颜色。AMOLED的AM 部分(AM part)来自Active Matrix(Active Matrix)，代表屏幕背后的电子实现。
OLED和AMOLED(OLED and AMOLED)有什么区别？
OLED 屏幕可以使用两种类型的电子设备来控制它们显示的图片：PMOLED 和 AMOLED(PMOLED and AMOLED)。因此， OLED 和 AMOLED(OLED and AMOLED)之间没有区别，因为AMOLED是 OLED 显示器。
但是，PMOLED 和 AMOLED(PMOLED and AMOLED)之间存在差异。PMOLED来自Passive Matrix OLED，它是一种没有存储电容器(storage capacitor)的电子设备。我们已经知道，AMOLED代表(AMOLED)Active Matrix OLED，它的电子驱动器有一个存储电容器(storage capacitor)。
AMOLED比LCD好吗？
有人认为AMOLED比LCD好，而另一些人则相反。但是，这两种显示技术各有利弊：
- AMOLED显示器可以独立点亮或关闭每个像素，这意味着它们可以提供比LCD屏幕更好、更自然的色彩。LCD（液晶显示器(Liquid Crystal Display)）屏幕不会独立点亮其像素：它们使用背光和实际上阻挡其背后的白光以产生颜色的像素面板。该技术无法提供与AMOLED相同的自然色彩。
- 此外，由于它们显示颜色的方式不同，AMOLED 和 LCD 屏幕(AMOLED and LCD screens)在提供的亮度水平方面也不相同。AMOLED 显示器(AMOLED display)上的每个像素都有自己的微型光源(light source)，而LCD具有通常由显示器后面的灯提供的背光。因此，LCD屏幕往往提供比AMOLED 显示器(AMOLED display)更高的亮度水平。
- AMOLED 和 LCD 屏幕(way AMOLED and LCD screens)点亮像素的方式的另一个结果是， AMOLED提供真正的黑色（通过独立关闭像素），而LCD提供更干净的白色（因为它具有更强的背光）。
- 当谈到在由电池供电的屏幕上使用AMOLED 或 LCD时，(AMOLED or LCD)功耗(power consumption)是一个问题。因为AMOLED可以完全独立关闭像素，你可能会认为它比LCD更(LCD)省电(power efficient)。但是，这取决于您使用设备的方式。当AMOLED(AMOLED)显示器显示的图像没有太多白色时，它们比LCD屏幕需要更少的功率，但当它们显示大量白色时消耗更多的功率。当有很多鲜艳的颜色要显示时，AMOLED需要更多的电源来打开它的像素。另一方面，LCD(LCDs)需要相同的恒定量无论(power regardless)它们显示的图像类型如何，都可以使用电源，因为它们的背光始终亮着。
- AMOLED屏幕的像素中有有机成分，而LCD(LCDs)则没有。这意味着AMOLED屏幕的使用寿命往往低于LCD(LCDs)。
- 由于OLED 技术(OLED technology)价格昂贵，AMOLED显示器的制造成本比LCD(LCDs)高。

AMOLED 与 IPS LCD
IPS LCD代表In-Plane Switching Liquid Crystal Display，是对LCD技术(LCD technology)的改进。IPS LCD提供比传统 TN（扭曲向列(Twisted Nematic)）LCD 屏幕(LCD screen)更自然的亮度、对比度和色彩，以及更宽广的视角。但是，我们在本文上一节中谈到的所有优点和缺点仍然适用。AMOLED与IPS LCD没有明显的赢家，因为这两种技术都有其优点和缺点。
AMOLED的好处
AMOLED的主要优点是这种类型的屏幕可以为您提供纯黑色、鲜艳的色彩和强大的对比度。(contrast ratio)如果你想要所有这些，你应该考虑购买带有AMOLED屏幕的设备。
您希望您的设备使用AMOLED显示器吗？
现在您知道AMOLED代表什么以及为什么它是一项伟大的技术。你也知道为什么没有人可以说它是最好的显示技术(display technology)，以及为什么其他显示技术如IPS LCD(IPS LCD compete)与它竞争。您想要AMOLED提供的真正的黑色和鲜艳的色彩吗？还是您更喜欢便宜的液晶显示器(LCD)？在下面的评论中分享(Share)您的想法。
Simple questions: What is an AMOLED screen? What does AMOLED mean?
AMOLED is a display tеchnolоgy that is used on many ѕcreens. Most of them are usually found on smartphones, so if you have been looking for a smartphone, from brands like Samsung or Google Pixel, you might have stumbled on ѕome that brag about hаving AMOLED displays. Do you know what AMOLED stands for and what it is? If you want to know the answer and see why AMOLED is bоth good and bаd, read on:
What does AMOLED screen mean?
AMOLED is a type of OLED display and an acronym for Active Matrix Organic Light Emitting Diodes. The OLED part means that the display uses LEDs and an organic compound made of carbon and other substances to light up and display colors. The AM part of AMOLED, which comes from Active Matrix, represents the electronic implementation behind the screen.
What is the difference between OLED and AMOLED?
OLED screens can use two types of electronics to control the pictures they display: PMOLED and AMOLED. Thus, there is no difference between OLED and AMOLED, as AMOLED is an OLED display.
There are differences, however, between PMOLED and AMOLED. PMOLED comes from Passive Matrix OLED, and it is an electronics implementation that does not have a storage capacitor. AMOLED, as we already know, stands for Active Matrix OLED and its electronics driver has a storage capacitor.
Is AMOLED better than LCD?
Some people think that AMOLED is better than LCD, while others argue about the opposite. However, there are pros and cons to both these display technologies:
- AMOLED displays can light up or turn off each of their pixels independently, and that means that they can offer much better and more natural colors than LCD screens. LCD (Liquid Crystal Display) screens do not light up their pixels independently: they use a backlight and a panel of pixels that actually block the white light behind them to make colors. This technology cannot offer the same natural colors as AMOLED can.
- Also because of the different way they display colors, AMOLED and LCD screens are not the same when it comes to the level of brightness they can offer. Each of the pixels on an AMOLED display has its own tiny light source, while LCD have backlights that are usually provided by lamps behind the display. Thus, LCD screens tend to offer higher brightness levels than AMOLED displays.
- Another consequence of the way AMOLED and LCD screens light their pixels, is that AMOLED offers true blacks (by turning off pixels independently), while LCD offers cleaner whites (because it has a stronger backlight).
- When talking about the use of AMOLED or LCD on a screen powered by a battery, power consumption is an issue. Because AMOLED can completely turn off pixels independently, you might assume that it is more power efficient than LCD. However, that depends on how you use your device. AMOLED displays need less power than LCD screens when the images they display do not have much white but consume more power when they display a lot of white. When there are lots of bright colors to be displayed, AMOLED needs more power to turn on its pixels. On the other hand, LCDs need the same constant amount of power regardless of the type of images they display, because their backlight is always on.
- AMOLED screens have an organic component in their pixels, while LCDs do not. That means that the lifespan of AMOLED screens tends to be lower than that of LCDs.
- Because OLED technology is pricey, AMOLED displays are more expensive to manufacture than LCDs.

AMOLED vs. IPS LCD
IPS LCD stands for In-Plane Switching Liquid Crystal Display, and it is an improvement of the LCD technology. IPS LCD offers more brightness, contrast, and colors that look more natural than a traditional TN (Twisted Nematic) LCD screen, as well as much broader viewing angles. However, all the pros and cons we talked about in the previous section from this article still apply. There is no clear winner when it comes to AMOLED vs. IPS LCD, as both technologies have their strengths and weaknesses.
The benefits of AMOLED
The main benefits of AMOLED are the pure blacks, bright colors and strong contrast ratio that this type of screens can give you. If you want all that, you should look into buying devices with AMOLED screens.
Do you want your devices to use AMOLED displays?
Now you know what AMOLED stands for and why it is a great technology. You also know why nobody can say that it is the best display technology and why other display technologies such as IPS LCD compete with it. Do you want the true blacks and bright colors offered by AMOLED? Or do you prefer the cheaper LCD? Share your thoughts in the comments below.
