OLED TV cheaper LCD TVs can buy it?

The development of science and technology makes people's lives simple and rich, and there are many ways to obtain video entertainment information. I am afraid that except for the generations of grandparents who will watch TV programs, the younger generation may be more inclined to look at their favorite programs on a tablet or mobile phone. This kind of change came so suddenly that it almost got the TV out of the stage of history and became the “wall” of the living room.
However, this kind of stimulus is a bad thing. It has accelerated the iteration of television display technology. Major manufacturers are also trying hard to promote the birth of new technologies, trying to make consumers see the irreplaceability of televisions in the living room entertainment. Therefore, OLED TV emerged as a powerful contender for the new generation of display technology.
Since 2013, OLED panel technology has gradually matured. From the beginning of the positioning of the high-end, to the current price is increasingly close to the people, the advantages of OLED TV has become more and more obvious. In the past, LCD TVs (LCD TVs), which had beaten the traditional CRT for nearly 20 years and continued to dominate the TV market, are now really going to get off the altar?
OLED TVs are getting cheaper. Is LCD TV worth buying?
As it happens, I also have a lot of friends who claim to be “middle class” and want to change to a good TV with a high fortune, but they are still confused about the emerging display technologies. Given that many people are currently confused about the choice of traditional LCD TVs or OLED TVs, where does OLED TVs stand? Do I really need to spend more on these new technologies?
Although many people seem to have a clear understanding of the differences between LCD and OLED technologies, the difference between these two technologies is not as simple as it seems. Taking into account that more and more people are still tangled in the purchase of OLED or LCD, today the author from 1. light degree, 2. color, 3. black field performance, 4. response time, 5.HDR effect, 6. visible Multiple technical dimensions such as angles, prices, etc., are analyzed one by one. The purpose is to let everyone truly understand what their needs are and make decisions that are most suitable for them when purchasing.
OLED has obvious advantages in terms of lightness and black-field performance. • The technology is at the bottom. Is there any difference between LCD and OLED?
First of all, we must know that LCD and OLED are two completely different display technologies. There is an essential difference between the two in terms of the principle of light emission, and these "nature" differences have led to the "abbreviation" of the two types of television products.
From a literal point of view, LCD (Liquid Crystal Display) is the "liquid crystal display" technology, LCD TVs is what we often say LCD TVs, is a kind of liquid crystal display technology TV using LED (light emitting diode) as backlight light source.
The OLED (Organic Light-Emitting Diode) is literally referred to as "organic light emitting diode". Its biggest difference from the LCD is that it has the property of "self-luminous". The components of the organic light emitting semiconductor can "self-illuminate" and do not require "backlight". "Source" support.
Literally, many people may still not understand: What does "self-luminous" mean? How to achieve OLED technology? It doesn't matter that people in the industry have made a very graphic metaphor for the difference between OLEDs and LCDs: "OLEDs and LCDs, one like the sun and the other like the moon."
Of course, OLEDs are the sun because all stars are "self-illuminating," so no matter which angle you look at it, it's bright.
The LCD is more like the moon, because the planet itself does not emit light, needs an auxiliary light source, and emits light through refracted light; the light source of the LCD is the backlight behind the screen, which illuminates the display through refraction.
· Streamlined module architecture makes OLEDs have a clear advantage in lightness and thinness
Compared with the liquid crystal technology with complex structure, OLED display technology does not need backlight support, so it saves the liquid crystal and backlight module, the structure is very simple, the body can naturally achieve the ultimate ultra-thin, probably can achieve the traditional LCD 1 /3 Thickness.
The world's thinnest wallpaper TV, only OLED display technology can be achieved at present, the thickness of 2.57mm is enough to make people stagger. The OLED display technology is not only thinner and lighter, but its advantages are also reflected in the product form.
The flexible and flexible nature of OLEDs can be applied not only to televisions but also to smart devices in the future. Combined with the thin features of OLEDs, the screen can be made as thin as a piece of paper, and can be bent and folded freely. This is unthinkable in the LCD era.
·Because light and thin "screen sound" this black technology can only be achieved by OLED
Last year, OLED TVs implemented black technology that we have never heard of before. This technology comes from Sony's 2017 flagship product, the XBR-A1E Bravia 4K OLED TV. Its miraculous thing is that the product can be sounded through the screen without depending on the sound unit; in other words, the TV screen is equivalent to a speaker. This technology can save space inside the TV and give full play to the ultra-thin advantages of OLED without backlight.
Because the structure of the liquid crystal screen is relatively complicated, the backlight layer and the liquid crystal material layer are divided, and the vibration affects the deflection of the liquid crystal molecules. Therefore, the technology of generating sound by screen vibration can only be applied to an OLED television with a relatively simple structure and light weight.
Therefore, the degree of lightness: OLED wins.
· Black field performance: OLED wins the black field performance can also be called the black level: refers to the screen in the display of the darkest color, how can the "black" to what extent. To give a simple example of reality: students who often play games should be more clear, in the game reading stage, are generally black screen status, the bottom of the screen will generally appear "Now Loading" white lettering. This is the best time to test the performance of LCD and OLED black fields.
Due to structural limitations, LCDs typically achieve a black appearance by shielding white light, so it is very difficult to display true black. Strictly speaking, LCD TVs can't bring true black. After all, the shielding effect is no better, or there will be some light leakage phenomenon. Even the QLED QD backlight systems that have shown great success in recent years can't guarantee complete leakage.
The OLED has the characteristics of electroluminescence. Each pixel can emit light independently. The light source can be controlled spontaneously. As long as the light emitting mechanism is turned off, it can bring true black. Therefore, there is no possibility of light leakage under the black field, thereby improving the contrast and image quality. Therefore, for those gamers who are pursuing the ultimate experience and sense of substitution, I am afraid that only OLED TVs can meet their needs.
In addition, it is worth noting that because the OLED is self-luminous, the wavelength is closer to natural light and less harmful to the human eye, and LCD display technology will inevitably cause blue light damage to the eyes, although short-term viewing has little impact. However, if there are 1-10-year-old children in the family, it is necessary to properly control the time the children watch TV.
OLED solves the smear problem HDR effect is uncontested · Response time: OLED wins When we buy computer monitors, we may often hear the word response time, in fact, the TV industry also has this parameter, but manufacturers generally do not Since it was widely publicized, it was ignored by the general public. When we usually watch sports games, we will inevitably encounter "ghost image" phenomena, and these afterimages will frequently appear on high-speed objects.
The response time of the screen usually refers to the speed at which each pixel of the television reacts to the input signal, that is, the time required for the pixel to turn dark or turn from bright to dark. The shorter the time, the faster the screen response time and the less likely it is to cause smearing.
Due to the “congenital differences” in the construction of LCD TVs and OLED TVs, LCD TVs cannot fundamentally solve the phenomenon of “image afterimages” by any means or technology. We want to change the brightness and darkness of LCD pixels, we must perform a certain deflection of the liquid crystal molecules; and the liquid crystal molecules from the request to drive the chip to change the state of the process takes a certain amount of time, which is what we often say "response time" .
We can use technology to minimize the response time of LCD TVs. At present, the best LCD TVs have a response time of about 2ms. Therefore, the phenomenon of afterimage of the LCD screen is doomed to "cannot eradicate" and can only be avoided as much as possible.
In contrast, OLED TVs can directly control the brightness and darkness of pixels due to the “self-illumination” property without the need to deflect the liquid crystal molecules like the LCD. This results in OLED TVs that are far superior to LCD products in response speed, and even more than 1,000 times faster than plasma TVs. Therefore, we can hardly see the phenomenon of afterimages with the naked eye. In terms of expressiveness of high-speed dynamic images, OLEDs have a relatively large advantage.
Therefore, for friends who love watching sports games and playing video games, the response time parameter must be paid more attention. If you want to select LCD TVs, you are recommended to purchase products with 4ms or higher response time. If you choose OLED TVs, you can ignore the afterimage problem.
HDR effect: The concept of HDR is the first time we heard that it should come from a camera or mobile phone. HDR's full name is High Dynamic Range, which means high dynamic range; where dynamic range refers to the range of brightness and contrast, high dynamic range has a wider range of brightness and darkness and higher light and dark contrast, to put it plainly is to make the screen brighter Brighter, darker shades make the image more impactful.
TV HDR is a very different technology, but it differs in how it changes the picture. The most important aspect of HDR is the increase in brightness. The increase in brightness can make the picture more realistic, especially in outdoor scenes. In TV display technology, the problem to be solved by HDR is to make the contrast between bright and dark images clearer and clearer.
LCD TV is mainly achieved by changing the backlight and the interaction of the liquid crystal molecular layer. The backlight of the bright place is turned up, and the backlight is turned down or turned off in a dark place so as to adjust the entire block backlight to achieve the best The display effect.
In contrast, OLED TVs, thanks to the unique light-emitting characteristics of each pixel, each pixel can be closed to achieve a pure black, which is the OLED TV in the black field performance advantages mentioned earlier. Under the background of black, the brightness and darkness of the picture will be more obvious.
In short, whether it is LCD or OLED, if you want good HDR effect, you must buy high-end products to experience the “standard” HDR effect. HDR TVs under 10,000 yuan can basically only be “listening” Now. For more details, please refer to: "HDR Measured Tells You: The Picture Quality of Television Less Than 10,000 Yuan."
LCD prices are more pro-people OLED performance is more superior · Visual angle: OLED wins Usually we watch TV at home is to accompany the family together, because sitting in different corners of the sofa, and everyone's viewing angle is not the same, so TV's Visual angles are particularly important.
At the viewing angle, the vertical polarizer structure of the LCD display technology limits its viewing angle. Since the light source providing the liquid crystal display has a certain directionality when it is output after being refracted and reflected, viewing beyond this range results in a phenomenon of color distortion. Although technologies such as IPS and curved screens can improve the perspective of LCD display technology, there are still some dead ends.
OLED TVs do not have a perspective issue, and they are basically the same from an extreme perspective. OLED TVs have a good colorimetry perspective and horizontal and vertical contrast viewing angles. They can maintain the true colors of the screens and the images are very good. Layering.
· Price: LCD wins prices are always the most concerned issues for consumers. In the past few years, OLED TVs still belong to the “middle class” high-end gadgets; after all, advanced players who are pursuing the ultimate experience are only paying attention to the “value” of the products. "Not "price". Take Sony's case: Senior executive vice president Ichiro Takagi once revealed the consumer portraits of Sony TV in the interview: 1. The movie and TV drama fans, 2. The sports enthusiasts, 3. The game players.
Therefore, Sony is very clear that the core consumer groups of its own products have not changed – they are all consumers who pay attention to the quality of life and are willing to pay for high-value-added products, which is the main role in the “consumption upgrade” trend. Middle class."
Due to the shortage of panel supply, OLEDs have high pricing in the early stages of development. However, the middle class is only a minority after all. Currently, the biggest market obstacle faced by OLED TVs is still the price issue.
Since OLEDs were in the early stages of development, only LG Display was supplying OLED panels globally. Therefore, the relative production capacity of LCD panels is very limited. This reality is doomed that OLED TVs can only target 2% of the global high-end market. The price of the same size and same function is at least more than one fold, and the price of OLED TVs has even become 3-5 times that of mainstream LCD TVs.
In 2013, LG released the first OLED TV, which was priced at 14,000 US dollars (approximately 88,828 yuan), really can be described as "magically assassinated"; came to 2018, 55-inch 4K OLED TV The price has dropped to around ten thousand yuan.
Although OLED prices continue to decline, the price gap with LCD TVs still exists for a short period of several years. The price of OLED TVs has dropped by nearly 10 times, gradually entering a relatively close to the main selling price, and OLED's determination to enter the mainstream market. Big, no doubt will make the LCD feel more anxious.
However, by opening up major e-commerce platforms, we can still clearly see that although OLED TVs have already experienced significant price reductions over the past few years, there are only a handful of models below 10,000 yuan, and prices are basically locked in. The price range of 10000~20000. In contrast, the current mainstream LCD TVs, the price is concentrated in 4000 yuan, the price advantage is more obvious.
At present, in the face of this price gap, we have to understand whether these “additional values” of OLED TVs are more than traditional LCD TVs. Do you really need them? Are you willing to make concessions on "price" for these "values"?
Combining the above, we have conducted multi-dimensional technical analysis of LCD and OLED TVs from several dimensions. OLED technology is leading the LCD and is superior to LCD in many display indicators. My recommendations are:
If you are a high-end user, game player or Blu-ray enthusiast who is pursuing the ultimate experience, you are not hesitant to choose OLED TVs for the harsh response speed and black market performance.
If you don’t have high requirements for the quality of the screen, usually only occasionally watch TV programs with your family, the price of LCD TVs is even more grounded. Compared with OLED, it still has a certain degree of competitiveness, so buying an LCD TV is also A good choice.
The author carefully promotes the differences between LCD and OLED TVs in these TV products. The previous article has already done a detailed analysis for you. If you are still not clear on how to choose, I recommend the following three television products for you:
· Cost-effective choice of LCD TVs Internet TVs are more pursuing rich content and user-friendly operating systems. In recent years, Hisense has developed a very distinctive VIDAA system, and has integrated a variety of useful and attractive technologies. With a wide variety of rich content resources, thanks to its excellent product technology and supply chain advantages, Hisense's TV products have always been the darling of domestic consumers, and Hisense LED55EC720US is among the best of these darlings. 55 Moderate size, multi-core processor performance is strong. Ultra-thin +4K+ all-metal, this entry-level all-around player you deserve. Price 3999 yuan
· In the trend of high-end LCD TVs being preferred in consumer upgrades, consumers are paying more attention to TV quality performance. TCL C5 TVs have been pursued with their excellent exterior design, carefully-crafted details, and Harman Kardon's high-quality sound effects. High-quality urban white-collar workers love. Modern, high-end, exquisite, enough to meet the modern urban people's pursuit of taste and quality. Price 8199 yuan
· The pursuit of the ultimate game player choice Sony's insistence and pursuit of picture quality is well-known, if you are an ultimate game player, ordinary 4K display is far from meeting you, this from Sony's KD-55A1 OLED TV is definitely your best choice. Whether from the "screen sound", color or black field performance is unmatched by other mainstream LCD TVs. After all, the price of 17699 will make many people discourage. However, when you see this TV, I'm afraid you will feel that this money is worth it! Sale price 17699 yuan
Written at the end:
The traditional LCD TVs that have occupied the TV market for nearly two decades now seem to have “have exhausted” at the current node, and the argument that the LCD era will be terminated has been buzzed up in the near future. The facts prove that the development momentum of OLED TVs in recent years is extremely fierce. It is a foregone conclusion to occupy the high-end TV market. It can be said that further replacement of LCD TVs is just around the corner.
However, OLED's road ahead is not easy. At present, two intangible electroluminescent QLEDs and Micro LED technology are pressing the OLEDs. The Micro LED has both power consumption and brightness performance. Better than OLED, but at this stage, the price of Micro LED panel is a bit too high - it is like the OLED panel in the LCD panel in previous years.
Although QLED technology still belongs to the LCD camp at this stage, QLED currently developed by Samsung is a quantum dot light-emitting diode display technology based on electroluminescence characteristics. That is to say, the final development direction of QLED is still “self-luminous”. As a result, OLEDs, QLEDs, and Micro LEDs have all recognized self-illumination technologies. It seems that the pattern of the next TV era seems very clear.
