我们打赌您听说过OLED 电视(OLED TVs)。如今，每个科技(Every tech)零售商都在出售它们。也许您甚至对OLED 电脑(OLED computer)显示器感兴趣。但是，你知道OLED是什么意思吗，为什么它好，为什么它不好？你想知道你是否应该把钱投资在OLED 屏幕上(OLED screen)吗？如果你这样做了，请继续阅读，你会找到答案：
什么是OLED？
OLED是Organic Light Emitting Diode的首字母缩写词，它代表了一种用于显示器的技术。OLED显示器有一层由有机材料（碳和其他物质）制成的层，夹在两个电极之间，当给定电力时，它们会发光。
OLED有什么好处？
OLED显示器上的像素独立点亮，因为它们中的每一个都可以独立接收电流。这意味着OLED显示器不像传统LCD显示器那样需要额外的背光。一个重要的结果是OLED显示器比LCD屏幕更薄更轻。
OLED的另一个好处是它的图像质量(image quality)。OLED显示器可以独立点亮每个像素，也可以独立关闭每个像素。当没有电流通过像素时，它实际上是关闭的，这意味着它尽可能接近绝对黑色。这使得OLED显示器比传统的 LCD 屏幕更具优势，传统的LCD屏幕总是打开背光，因此永远无法在它们显示的图像上获得“真正的黑色”。OLED显示器的另一个重要方面是它们可以提供极高的对比度(contrast ratio)。我们已经知道OLED可以显示绝对黑色，但它也可以使用所需的确切亮度级别为每个像素着色，因为它所需要的只是将更多的电流发送到该特定像素。
OLED和LED(OLED and LED)有什么区别？
O LED与(LED)LED相同，但添加了额外的有机材料。LED来自发光二极管(Diode)，代表一种双引线半导体光源。
OLED和LCD(OLED and LCD)有什么区别？
OLED 显示器(OLED display)使用(s use)独立点亮的像素，而LCD 屏幕(LCD screen)使用(s use)背光来显示图像。在OLED 显示器(OLED display)中，如果需要，每个像素都有自己的“背光”，它将自己的光发送到世界。在LCD 屏幕(LCD screen)中，整个屏幕都有一个背光源，通常由一盏灯提供，光线穿过显示器中的像素。在LCD 屏幕上(LCD screen)，像素不会发出自己的光，而是会阻止背光（来自灯的）离开。不管(Regardless)做的再好，没有一个液晶屏(LCD screen)能完全挡住它接收到的背光，也就是说没有液晶屏(LCD screen)可以提供与OLED 屏幕(OLED screen)相同的“真黑” 。
OLED的缺点是什么？
OLED屏幕的主要缺点是它们通常无法提供与LCD屏幕相同的高亮度。但是，如果考虑到更好的对比度(contrast ratio)，OLED屏幕即使不是更好的体验，也接近提供相同的体验。
OLED显示器还具有比LCD 显示器(LCD)寿命短的负面影响。不幸的是， OLED(OLED)显示器中使用的有机材料会随着时间的推移而退化，导致颜色损失(color loss)，尤其是蓝色(color blue)的损失。但是，LG 等顶级OLED制造商一直在努力解决问题，以延长其屏幕的使用寿命。例如，目前OLED 电视(OLED TV)的预期寿命可以从 10 年到 20 年或更长，平均每天使用大约 6 或 7 小时。
最后，OLED尚未普及的另一个重要原因是制造OLED屏幕的成本高于制造LCD屏幕的成本。此外，这也意味着OLED屏幕并不是您所说的负担得起的，尽管它们的价格在过去几年中一直在下降。
您想要 OLED 电视还是显示器？
现在您知道OLED代表什么，哪些是它的最佳资产以及OLED 和 LCD(OLED and LCD)之间的区别。你渴望OLED电视(OLED TV)吗？或者也许是电脑显示器(computer monitor)？您(Are)准备好为此付出高昂的代价了吗？在下面的评论部分分享(Share)您的想法。
Simple questions: What is OLED? What does OLED mean?
We bet that you have heard about OLED TVs. Every tech retailer sells them nowadays. Maybe you have even been іnterested in OLED computer monitors. But, do you know what OLED means, why it is good and whу it is bad? Do you want to know whether or not you should invest yоur money in an OLED screen? If you do, read on, and you are going to find yоur answers:
What is OLED?
OLED is an acronym for Organic Light Emitting Diode, and it represents a type of technology that is used for displays. OLED displays have a layer made of organic material (carbon plus other substances) sandwiched between two electrodes which, when given electrical power, emits light.
What are the benefits of OLED?
The pixels on OLED displays are lit independently as each of them can receive electrical current independently. That means that OLED displays do not require additional backlight the way traditional LCD displays do. One important consequence is that OLED displays are thinner and lighter than LCD screens.
Another benefit of OLED is its image quality. OLED displays can light each of their pixels independently, and they can also turn off each of them independently. When no electrical current goes through a pixel, it is effectively off, which means that it is as close to absolute black as possible. That gives the OLED displays an edge over traditional LCD screens which always have the backlight on, and thus are never able to obtain "true blacks" on the images they display. Another essential aspect of OLED displays is that they can offer an extremely high contrast ratio. We already know that OLED can display absolute blacks, but it can also color each pixel using the exact brightness levels needed, as all it takes is more electric current sent to that specific pixel.
What is the difference between OLED and LED?
OLED is the same as LED but with additional organic material added. The LED comes from Light-Emitting Diode and represents a two-lead semiconductor light source.
What is the difference between OLED and LCD?
OLED displays use independently lit pixels, while LCD screens use a backlight to display images. In an OLED display, each pixel has its own "backlight" if you want, which sends its own light into the world. In an LCD screen, there is a backlight source for the entire screen, that is usually offered by a lamp, and that light goes through the pixels found in the display. On an LCD screen, pixels do not throw their own light, but rather block the backlight (from the lamp) from getting out. Regardless of how well it is made, no LCD screen can completely block the backlight it receives, which means that no LCD screen can offer the same "true black" as an OLED screen can.
What are the downsides of OLED?
The main downside of OLED screens is that they are not usually capable of offering the same high level of brightness as LCD screens can. However, if you take into consideration the much better contrast ratio, OLED screens are close to offering the same if not a better experience.
OLED displays also have the negative aspect of being shorter lived than their LCD counterparts. Unfortunately, the organic material used in OLED displays tends to degrade over time, resulting in color loss, especially the loss of the color blue. However, top OLED manufacturers such as LG have been working hard on a fix to prolong the lifespan of their screens. The current expected lifetime of an OLED TV, for example, can go from as little as 10 years and as far as 20 years or more on average daily use of about 6 or 7 hours a day.
Finally, another important reason to OLED not being everywhere yet is the fact that manufacturing OLED screens cost more than manufacturing LCD screens. Moreover, that also means that OLED screens are not what you would call affordable, although their prices have constantly gone down in the last couple of years.
Do you want an OLED TV or monitor?
