In recent years, OLED has been regarded as the next-generation display technology, and its panel's self-luminous characteristics enable the image quality to be effectively enhanced. The appearance of QLED TV seems to have caused people's attention to shift. QLED TV's excellent picture quality has allowed many manufacturers to start the "team" two major panel camps. In August this year, Sharp released the world’s first consumer-grade 8K TV. The emergence of the concept of 8K has also allowed manufacturers and consumers to discover a new road for the future development of TV. In the days when TV manufacturers have supported QLEDs and OLEDs today, the emergence of 8K is not a big gambling of “swords go†but a new challenge for technology. In the quality war that follows the price war, 8K will rely on what advantages to break the limitations of OLED and QLED? Today, let me know about it with the author.
The popularity of OLEDs has not been effective for many years. The popularity of OLED TVs is still gloomy. OLEDs, that is, organic light-emitting diodes, are different from our common LCD TVs. OLED TVs have a "genius" - self-illumination. This means that OLED TVs do not require a backlight source and can be imaged with self-illumination. Its self-luminous properties allow contrast to achieve stunning contrast. At the same time, since no backlight source is required, the OLED presents more pure colors, and it can exhibit extreme white and black.
Despite the incredible intensity of picture quality, OLEDs have not been as popular as people think after years of experience. Many manufacturers have released OELD products or joined the OELD camp this year, including Sony, Philips, and Panasonic. Although this makes the OLED TV market look rather lively, after years of popularity, the penetration of OLED TVs is still not satisfactory. In 2014, NPD DisplaySearch predicted that the shipment rate of OLED TVs will exceed 1 million units in 2014, and in 2016, the OLED TV market penetration rate will exceed 3%. However, unlike the imagination, only 340 million OLED TVs were shipped in 2015. Subsequently, in 2016, the shipment rate of OLED TVs was still less than 3%, and only 720,000 shipments were bleak.
The failure to achieve the desired results is in fact related to the few technical limitations that OLED panels have yet to break through. First, the use of OLEDs in large screens has the disadvantage of having a short lifetime. With the use of users, OLED TVs will have different levels of natural fading. Although OLEDs have also been used in mobile phones in recent days, the frequency of mobile phone product replacement is significantly higher than that of point-to-point televisions. At the same time, OLED TV prices are relatively high, if you can only use a short period of 3 to 4 years after purchase, it is clearly contrary to the people's spending habits. Finally, the defect of OLED TV "burning screen" still exists, Apple officials also said to burn screen The appearance of the phenomenon is still not completely avoided and can only be minimized. It is these deficiencies that cannot be improved that OLED TVs have not yet become the mainstream of development.
The sudden emergence? The current QLED is not a "full body"
In the past two years, the emergence of QLED has also seen more possibilities in the industry. The real QLED has not yet come out of the laboratory and has not really appeared before consumers. It is expected that the QLED will not be available until 2020 at the earliest. From the imaging principle, QLED TVs stimulating quantum dots of different radii through currents, and thus exhibit different colors. This kind of QLED TV and OLED TV lighting mechanism is similar, and has the same self-luminous characteristics, also has considerable advantages in brightness and contrast and color. At present, QLED is still an improvement in backlight technology. Its backlight is added with a quantum dot film, which belongs to the optical quality sub-dot technology. It cannot achieve self-emission characteristics and requires a backlight source for stimulation, but its color and contrast are lower than those of ordinary televisions. There is also a certain degree of improvement.
What needs to be understood is that currently there is a need for "QLED TVs" that still require backlights. In fact, they should be called QD-LCD TVs. It is not the final form of QLEDs. This kind of QD-LCD TV will still cause the light leakage phenomenon of LCD TVs because of the use of the backlight source, and the performance of the TV in the dark field will be weakened. At the same time, the "quantum dots" used in televisions are commonly found in raw materials, and once they are used, they may cause adverse effects on the human body and may even cause cancer, and the EU has also banned *** in 2016. * Quantum-dot television imports. In terms of price, although "QLED TV" is better than ordinary TV, the price is still high, which is about twice that of similar TVs. This is also the reason why it sold only 600,000 units in 2016. one. Taken together, the performance of QLEDs at this stage has not yet reached expectations.
Open technology, industrial barriers 8K sounded popular horn In August of this year, Sharp took the lead in introducing the world’s first consumer-grade 8K TV, and officially kicked off the 8K prelude. When the picture quality evolves from 4K to 8K, it has basically reached the limit of current human eye vision. The 8K resolution is 7680*4320 pixels, which is 4 times that of the current 4K TV. At the same time, at 8K resolution, the number of frames in the picture will be limited to 120 frames, and the number of frames per second can reach 120, which is enough to make the human eye more accurate. At the resolution of 8K, the picture can achieve the same effect as the real one, enough to make the TV a window to connect with reality. In terms of listening effects, 8K video uses the 22.2-channel audio system within the Super Hi-Vision-SHV standard, providing immersive stereo experience.
From a technical point of view, 8K is not as technically difficult as QLED TVs and OLEDs, such as the lifetime problems that OLEDs and QLEDs have. In this first 8K TV, you can see that Sharp has given a satisfactory answer to 8K technology. Just this year, Foxconn and SDP signed the 10.5 Generation 8K project that has started construction in Guangzhou. Compared with OLED TVs whose panel output is still in doubt, 8K TVs clearly have sufficient advantages.
For the popularization of 8K, Sharp actually started not only from the technical level, but also through the improvement of the entire industrial chain, and gave birth to 8K "mature." In the upstream of the industry chain, the 8K resolution of 32 million pixels at 120 frames per second is also a challenge for transmission. In order to avoid repeating the mistakes of 4K TVs, Sharp started from the different levels of content, editing, transmission, and display to solve the obstacles of 8K popularization. Currently Sharp has launched 8K cameras and continues to implement them; Sharp's editing equipment can also be used for 8K video processing; with the advent of the 5G era, 8K video transmission speeds will also be resolved; 8K TV display terminals will eventually Allows users to experience the sharpness limits of human vision.
Comparing OLED, QLED, and 8K technologies, they are all created to improve the picture quality. If the current 4K technology cannot improve the picture quality, a new round of technological breakthroughs will be required. Obviously, 8K is based on This reason was born. But compared with OLEDs and QLEDs, 8K has been conquered and completed by Sharp, both in terms of technical difficulties and lack of industrial chain. It can be foreseen that 8K as a "future technology" is ready to accelerate into the home of ordinary consumers in the multi-advantages and further consumer demand for picture quality. We will also experience Sharp and 8K in the future. More surprises for us.
