您想购买一台新电视，但对到处乱扔的所有首字母缩略词感到困惑。只不过是用于显示器的首字母缩略词。液晶显示器(LCD)？QLED ? 4KHD？这些甚至意味着什么？
在进行大宗购买（例如全新的平板电视）时，您可能会寻找物有所值的最佳选择。你可以做出明智的决定的唯一方法就是被告知。
首字母缩略词代表什么，哪个是更好的选择？这些是我们今天将通过提供头对头比较和每个常用面板显示选项的简要概述来回答的问题。
LCD 与 LED：背光电视显示器之间的区别(LCD Vs LED: The Difference Between Backlit TV Displays)
在深入进行一对一比较之前，我们应该先了解一下背光是什么、类型、每个首字母缩写词在与显示面板有关时代表什么以及它们是什么。
背光(Backlighting)
背光的定义就在这个词中：从背面照亮的过程。换句话说，它会点亮您正在观看的电视屏幕上的图像，在焦点上产生光晕，而其他区域保持黑暗。它有助于提高亮度、色彩质量和对比度，以便您可以观看自己喜欢的节目。
液晶电视(LCD TVs)中使用了三种基本的照明形式。它们中的每一个都很重要，但又不同。
- 冷阴极荧光灯 (CCFL)(Cold Cathode Fluorescent Lamps (CCFLs) ) – CCFL(CCFLs)是一种较旧的背光形式，已被废弃。一系列CCFL将位于(CCFLs)液晶(LCD)显示器后面的电视内部。这提供了相对均匀的照明，在整个屏幕上提供了相似的亮度水平。CCFL(CCFLs)比现在使用的LED阵列更大，因此意味着液晶电视(LCD TVs)的框架更厚。
- 全阵列(Full-Array)– 更换过时的CCFL ，我们在(CCFLs)LCD屏幕背面配备了全阵列LED 。(LEDs)这提供了LED(LEDs)获得局部调光的不同区域，能够根据对比度点亮或变暗。
- 边缘照明(Edge Lighting)-边缘(Edge)照明类似于全阵列，除了 LED 不是广泛的 LED 区域阵列，而是沿着(LEDs)屏幕(LED)的顶部、底部和侧面放置。可以对LED(LEDs)进行不同配置，从而产生不同的图像质量结果。这种背光的好处是制造商，因为他们能够以更低的成本制造更薄的电视(TVs)。
流行的电视显示术语(Popular TV Display Terms)
- 液晶显示器 (LCD)(Liquid-Crystal Display (LCD) ) – 利用液晶的光调制特性的平板显示器。由于液晶不能自行发光，因此使用背光或反射器来产生彩色或单色图像。
- 发光二极管 (LED)(Light-Emitting Diode (LED) ) – 一种半导体光源，当电流通过时会发光。以光子的形式使用所需的能量决定了发射的颜色。
- 超高清 (UHD) (Ultra High-Definition (UHD) )–(UHD)也称为超高清电视和超高清(Super Hi-Vision)电视，是一种宽高比为 16:9 的数字格式。
- 4K 分辨率 (4K)(4K Resolution (4K) ) – 大约 4,000 像素的水平显示器起源于电影放映行业。
- 有机 LED (OLED)(Organic LED (OLED) ) – 一种LED显示器，其中发射电致发光层（电流流动的路径）是位于两个电极之间的有机化合物薄膜。
- 量子 LED (QLED)(Quantum LED (QLED) ) – 准确地称为量子点显示器(Quantum Dot Display)，QLED使用量子点，这是一种半导体纳米晶体，可以产生纯单色红、绿和蓝 ( RGB ) 光。他们将背光转换为发出纯RGB，从而提高显示器的亮度和色域。
- MicroLED – 由微型LED(LEDs)阵列组成，以形成单个像素元素。提供比基本LCD技术更好的对比度、响应时间和能源效率。
- Mini-LED – LED 背光 LCD(LED-backlit LCDs)具有基于 mini LED 的背光，可实现更深的黑色和更高的对比度。
液晶与 LED(LCD vs LED)
与此列表中的所有首字母缩略词一样，这两个实际上是相同的，只是略有不同。LED 电视只是 LED 照明的液晶(LCD)电视，在图像和功能方面提供相似的质量，同时在此过程中消耗更少的能源。
LED 电视(LED TVs)还提供更多颜色，尤其是在使用 RGB-LED 背光时，具有更高的动态对比度，并且采用更纤薄的框架。对于标准LCD面板的所有这些轻微好处，LED 电视(LED TVs)将花费您一点点额外费用。
唯一的主要区别在于使用CCFL(CCFLs)提供照明的老式液晶电视。(LCD TVs)如今(Nowadays)，由于技术的进步，几乎所有以LCD形式销售的电视都可能是LED版本。(LED)因此，如果您在液晶(LCD)电视和LED电视之间徘徊，只需检查以确保液晶(LCD)电视不再使用CCFL(CCFLs)。这应该可以减轻人们对采取一种或另一种方式的担忧。
超高清与 4K(UHD vs 4K)
UHD是 4K——有点像。如今(Today)，4K 分辨率电视风靡一时。最初仅用于大屏幕上的电影放映的东西，现在可以在您的家中使用。但如果我告诉你，事实并非如此？
电影放映中使用的 4K 版本的分辨率为 4096 x 2160 像素。这看起来似乎很容易，因为 4096 实际上代表了名称中的 4K。但是，通常所说的 4K 或 4K UHD分辨率为 3840 x 2160 像素。(UHD)这意味着我们听到的用于电视的主要 4K 标准实际上根本不是 4K。这是一个近似值。
在宏伟的计划中，几个像素真的很重要吗？不，不是真的。无论如何，我们的眼睛几乎无法处理它。但是，当您看到标有UHD的电视和标有 4K 的电视时，您就知道他们说的是同一件事。至少在数字电视方面。
此外，4K 在更大的屏幕上更有效，但如果您购买的电视尺寸与您要更换的电视尺寸相似，您会更加注意到差异。8K 在很长一段时间内不会成为家庭中的主流，所以不要害怕挥霍一下。
OLED 与 QLED(OLED vs QLED)
OLED电视本质上是等离子屏幕的继任者。QLED电视是三星(Samsung)SUHD 电视(SUHD TVs)系列的品牌重塑。三星(Samsung)认为SUHD要么太混乱，要么不够吸引人，因此他们将其切换到QLED。SUHD中的“S”甚至不代表任何特定的东西。实际上，SUHD 只不过(SUHD)是一台具有UHD分辨率的液晶(LCD)电视。
对于SUHD实际拥有的使其能够从竞争对手中脱颖而出的东西，有一点需要注意：纳米晶体技术和三星自己的高(High) 动态范围(Dynamic Range)( HDR ) 版本，Peak Illuminator Ultimate/Pro。当然，纳米晶体技术实际上是量子点，如上述首字母缩略词概述所示。
Peak Illuminator的Pro版本提供侧光式局部调光，可以在更便宜的QLED/SUHD TVs中找到。Ultimate提供全阵列局部调光。局部调光是一种 LED 电视功能，可在显示黑色时调暗屏幕不同区域后面的背光。
(OLED TVs)QLED/SUHD TVsOLED 电视倾向于提供更明亮、更丰富多彩的观看体验，并提供更大的屏幕选项。如果必须要有更强劲的视觉效果，那么OLED将赢得这场对峙。
MicroLED 与 Mini-LED(MicroLED vs Mini-LED)
MicroLED是一种新的显示技术，它不像普通(MicroLED)LCD/LED TVs那样需要背光。Mini- LED更像是替代LED背光使用的LCD面板。LCD/LED TVs相比， Mini - LED 电视(TVs)将为消费者提供更高的对比度和更短的响应时间，但无法与OLED 电视(OLED TVs)相媲美。
在画质和对比度方面，MicroLED是OLED的重要竞争对手。这意味着MicroLED与Mini-LED的真正区别在于，Micro-LED正在逐渐成为成熟的下一代显示器。Mini-LED更有可能成为一种替代技术，用于增强已制造的显示技术。
对于任何宣传Mini-LED技术的电视来说，它只是意味着它是升级后的LED电视。(LED)Micro LED面板电视有可能成为下一个“大事”，因此今天投资一台电视可能会将您带入未来。
LCD VS LED: All the TV Acronyms You Need to Know
You’re looking to purchase a new TV but are confused by all of thе acronyms being thrown around. None morе so than the acronyms used for the displays. LCD? QLED? 4KHD? What do these eνen mean?
When it comes to making major purchases like a brand new flatscreen, you’re likely looking for the best bang for your buck. The only way you can make an informed decision is, well, by being informed.
What do the acronyms stand for and which one is the better choice? These are the questions we’ll be answering today by providing a head to head comparison and brief overviews of each commonly used panel display option.
LCD Vs LED: The Difference Between Backlit TV Displays
Before diving into the one versus one comparisons we should go over what backlighting is, the types, what each acronym stands for when pertaining to the display panels, and what they are.
Backlighting
The definition of backlighting is right there in the word: the process of illuminating from the back. In other words, it lights up the images on the TV screen that you’re viewing, creating a glow on the focal point while other areas remain dark. It helps with the brightness, color quality, and contrast so that you can watch your favorite shows.
There are three basic forms of illumination that have been used in LCD TVs. Each of them is important, but different.
- Cold Cathode Fluorescent Lamps (CCFLs) – CCFLs are an older form of backlighting that have been abandoned in its use. A series of CCFLs would sit across the inside of the TV behind the LCD display. This provided a relatively even illumination giving similar levels of brightness across the screen. CCFLs are larger than the LED arrays used today, and as a result meant that LCD TVs had thicker frames.
- Full-Array – Replacing the outdated CCFLs, we have a full-array of LEDs across the back of the LCD screen. This provided varying zones where the LEDs gained local dimming, the ability to light up or dim depending on the contrast.
- Edge Lighting – Edge lighting is similar to full-array except that instead of a wide array of LED zones, LEDs are placed along the top, bottom, and sides of the screen. The LEDs can be configured differently producing varying results in picture quality. The upside to this backlighting is for the manufacturers, as they’re able to make thinner TVs at a lower cost.
Popular TV Display Terms
- Liquid-Crystal Display (LCD) – A flat-panel display using the light-modulating properties of liquid crystals. As liquid crystals cannot emit light on their own, a backlight or reflector is used to produce colorful or monochrome images.
- Light-Emitting Diode (LED) – A semi-conducting light source that will emit light as current runs through it. The energy required for use, in the form of photons, determines the colors emitted.
- Ultra High-Definition (UHD) – Also known as UHD TV and Super Hi-Vision, is a digital format with an aspect ratio of 16:9.
- 4K Resolution (4K) – A horizontal display of approximately 4,000 pixels originated for the movie projection industry.
- Organic LED (OLED) – An LED display where the emissive electroluminescent layer, the path where current flows, is a film of organic compound situated between two electrodes.
- Quantum LED (QLED) – Accurately referred to as Quantum Dot Display, QLED uses quantum dots, which are semiconductor nanocrystals, that can produce pure monochromatic red, green, and blue (RGB) light. They convert the backlight to emit pure RGB which improves the brightness and color gamut of the display.
- MicroLED – Consists of arrays of microscopic LEDs to form the individual pixel elements. Offers better contrast, response times, and energy efficiency to that of basic LCD technology.
- Mini-LED – LED-backlit LCDs with mini LED-based backlighting allowing for deeper blacks and higher contrast ratio.
LCD vs LED
As with all of the acronyms on this list, these two are virtually the same thing with a slight variation. An LED TV is just an LED-lit LCD TV, providing similar quality in terms of picture and functionality while consuming less energy in the process.
LED TVs also offer more colors, especially when using RGB-LED backlighting, have a higher dynamic contrast, and come in a slimmer frame. For all of these slight perks over the standard LCD panels, LED TVs will cost you a little bit extra.
The single major difference can be found in older LCD TVs, which used CCFLs to provide lighting. Nowadays, virtually every TV marketed as LCD is likely to be an LED version thanks to advancements in technology. So, if you’re on the fence between an LCD TV vs LED TV, just check to make sure the LCD TV is no longer using CCFLs. This should alleviate any concerns of going one way or the other.
UHD vs 4K
UHD is 4K – sort of. Today, 4K resolution TVs are all the rage. What had originally been used solely in cinematic projection on the big screen, is now available inside your home. But what if I told you, it’s actually not?
The version of 4K used in movie projection puts out a resolution of 4096 x 2160 pixels. This should seem like a no-brainer seeing as 4096 is in fact representative of the 4K found in the name. However, the 4K or 4K UHD resolution, as it is commonly referred to, sits at 3840 x 2160 pixels. This means that the dominant 4K standard we hear about for our televisions is not, in fact, 4K at all. It’s an approximation.
Does a few pixels really matter in the grand scheme of things? No, not really. Our eyes can barely process it anyway. However, when you see a TV labeled as UHD vs one as 4K, just know that they’re speaking of the same thing. At least in terms of digital television.
Also, 4K is more effective on a larger screen but you’ll notice the difference even more if you get a TV of similar size to the one you’re replacing. 8K won’t become mainstream inside homes for quite a while, so don’t be afraid to splurge a little.
OLED vs QLED
An OLED TV is essentially the successor to the plasma screen. QLED TVs are a rebranding of Samsung’s range of SUHD TVs. Samsung decided that SUHD was either too confusing or not catchy enough for marketing, so they switched it to QLED. The ‘S’ in SUHD didn’t even stand for anything specific. In reality, SUHD isn’t much more than an LCD TV with UHD resolution.
There is a slight caveat to what an SUHD actually has that would allow it to stand apart from competitors: nano-crystal technology and Samsung’s own version of High Dynamic Range (HDR), Peak Illuminator Ultimate/Pro. Of course, nano-crystal technology is actually quantum dots, as illustrated in the above acronym overviews.
The Pro version of Peak Illuminator offers edge-lit local dimming and can be found in the cheaper QLED/SUHD TVs. Ultimate provides full-array local dimming. Local dimming is an LED TV feature that dims the backlight behind different areas of the screen while black is being displayed.
OLED TVs tend to offer a brighter, more colorful, viewing experience and come with options of larger screens than QLED/SUHD TVs. If having punchier visuals is a necessity then OLED wins this faceoff.
MicroLED vs Mini-LED
MicroLED is a new display technology that doesn’t require a backlight the way that regular LCD/LED TVs do. Mini-LED is more of a replacement for LED backlighting used LCD panels. Mini-LED TVs will offer improved contrast ratios and reduced response time for consumers when compared to LCD/LED TVs but don’t stack up to OLED TVs.
When it comes to picture quality and contrast, MicroLED is a serious competitor to OLED. This means that the real difference when it comes to MicroLED vs Mini-LED is that Micro-LED is shaping up to be a fully-fledged next generation display of its own. Mini-LED is more likely to be a replacement technology used to enhance already manufactured display technologies.
For any TV touting Mini-LED technology, it just means that it’s an LED TV that got an upgrade. A MicroLED panel TV has the potential to be the next “big thing” so making an investment in one today will likely carry you into the future.
