The term “good†is dialectical on all issues, so it cannot be answered yes or no, but OLED, as the revolutionary newest technology in the television industry, does have unique advantages at some levels. From the image quality itself, OLED technology has the ultimate black expression, has almost unlimited contrast and viewing angle, fast response, these are the characteristics of excellent TV. In addition, because OLED is a kind of flexible and display technology, it is very easy to make a variety of curved and deformed TVs. Because the self-illumination structure is very simple, the overall thickness is much thinner than the liquid crystal, making it possible for “wallpaper TV†and even producing black technology such as CSO (screen sounding). It can be said that the birth of OLED technology has given the TV industry a great deal of extensibility, and the imagination in the later period is still very large.
In addition to OLEDs, the mainstream technology is liquid crystal, and all current Quantum-dot TVs are just LCD improvements. Some aspects of the stability and color purity of quantum dots are superior to those of OLEDs. In fact, they are mainly used to enhance the color gamut and color accuracy of LCD TVs, and their lifetime will be longer. However, the nature of LCD TVs has not changed fundamentally. .
In general, OLED technology is an advanced display technology that is completely different from liquid crystal. The current problem is that the cost is still relatively high, and the output is far from the ability to become mainstream. However, some unique features have already won a number of consumers. Currently, OLEDs are increasingly used in some high-end products.
It is really a good question. First of all, the old horse thinks that the fruit cell phone will not have much effect on television, but it does increase the degree of technical attention. The OLEDs of mobile phones and TVs are indeed different.
OLED panel is not used by Apple in mobile phones. There are too many machines used OLED. In fact, AMOLED is called in the mobile phone industry. This is not a more advanced technology than TV OLED, but a classification of OLED. AMOLED's English full name is Active Matrix OLED, which is active-driven OLED. The OLED screen we are currently in contact with, whether it is a smartphone or an OLED TV, is also an AMOLED screen, so when it comes to the term AMOLED, there is no need to think that it is more advanced than OLED.
However, although both are AMOLEDs, small-sized OLEDs for mobile devices and large-sized OLEDs for televisions are two very different implementations. The main manufacturer of small-sized panels is Samsung, which uses the RGB method, but it is not like the LCDs are horizontally arranged to form a sub-pixel, but the Pentile is arranged to explain why it is necessary to write a lot of non-human words. Everyone knows. The best solution based on the cost, different lifetime of RGB sub-pixels, and uniformity of light is just fine. The disadvantage is that the resolution is low at the same resolution.
TV does not use RGB horizontal OLED, but WRGB arrangement, so it is also called white OLED. Why do you want to do this, you can also write a large article, in short, it is based on the current best solution of yield, cost, energy saving, brightness output and other factors, in addition, because each pixel has four sub-pixels, the picture quality will feel more Delicate.
Obviously, no matter the size or size, in fact, the theoretical solution is not perfect, including the LCD camp also has a variety of attacks, such as white light OLED also uses the backlight, etc., in fact, only the sub-pixel filter, OLED or pixel from luminescent. Laoma has no intention of participating in the lineup. Can only say that OLED is still relatively new, there is a cloud of Chinese sayings, rather bullying young men and poor, OLED's progress is still very big.
3, Apple said that OLED screen burning is a normal phenomenon, OLED TV is also this?Is it immature?
The word burned first appeared on the PDP (Quantum Dot) TV. It is a common problem of many self-illumination technologies. There is nothing wrong with being normal. This is determined by the way the technology itself is displayed. Whether it is for OLEDs for mobile devices or OLED panels for TVs, in principle there may be burn-in. However, knowing this problem, we can also purposefully avoid him, minimize the long-term display and high brightness of repeated pictures, and so on.
As the manufacturer of OLED TV panels, LG DISPLAY has begun to solve the problem of burn screen. Laoma once saw a test machine in a non-open laboratory at the LGD headquarters. It worked 8 hours a day and it has been open for more than two years. KBS's logo did not see burn-in. There are no detailed information on how to achieve this. After a variety of understanding, it should be a combination of timing refresh technology and brightness monitoring and compensation techniques. Some TVs have built-in refresh tools to ensure that no burn-in occurs.
With regard to mature issues, OLED is still a relatively new technology after all, and it is constantly evolving. The problems such as narrow color gamut, slow response speed, and small viewing angle in the early days of liquid crystals have not been greatly improved. From another point of view, there is no perfect thing to do, and some gains will be lost. OLED is still the case. In the case of the entire burned screen, upstream companies are constantly making targeted improvements and believe that the situation will become better and better.
4, why the OLED screen TV is so expensive?
The output of OLED TV panels is currently only 1.7 million units per year, which is less than 1% of the global sales of 230 million units. In front of me, I also said that OLEDs are currently mainly high-end products. Many new technology and new products are born in the early stages, the business is to sell him more expensive. From an objective point of view, because the scale of manufacturing is not yet large, the integration level of the entire industrial chain has yet to be improved, and some key raw materials and manufacturing equipment are in the hands of specific companies. This is the main reason why OLED panels and TVs are still relatively expensive.
However, as the market's capacity becomes larger and larger, the cost of large-scale manufacturing will certainly become lower and lower. The precipitation of new technologies will also reduce the expectations of the entire industry chain for profits and enter a stable market environment. LGD has planned to put into production of a new OLED production line in Guangzhou (project review), and the P10 plant in Paju is also under construction. It is expected to reach an annual production capacity of 6.5 million pieces by 2020, and the 55-inch 2K panel price will drop below 1,000 US dollars. In terms of manufacturing principles, the materials needed for OLED manufacturing are far less than liquid crystals, and the structure is relatively simple. If the scale is equal to the LCD, the cost is lower than the LCD is a sure thing.
So, you still think expensive consumers wait and wait. But wait until then there may be new changes, perhaps with more advanced OLED evolution technology, or the legendary printed QLED. Taste new means that you have to pay more for it, and waiting for it means universal. By then, you certainly won't feel happy about using OLED. Buying a flat-screen TV and using it 10 years ago is definitely not a feeling!
5, Is there only LG in OLED screen TV? What is the global pattern?
This question is counter-productive. If it is asked whether there is only LG on the OLED TV screen, then my reply is yes. Currently, LG DISPLAY is the only company that mass-produces large-size OLED TV panels. The consumer OLED TVs that you can buy in the Chinese market are almost all LGD panels. However, other companies are also making efforts, such as BOE, etc...
If it is the original problem, then the answer is negative, LG Electronics is indeed a very early to do OLED TV business, but now the world has released OLED TV brand has 13. Among them, OLED TVs from LG, Sony, Philips, Skyworth, Changhong, and Konka should be available for purchase in China.
The global pattern, from the upstream perspective, will certainly be LGD's long-term dominance, but the popularity of the entire brand may be accelerated, perhaps after three years, you can hear the TV brand will have OLED TV release, even including Innumerable brands that expressed concern about OLED technology or did not do it in the past.
