With the upgrading of consumption, the development of the products in the home appliance market is currently in the direction of high-end, health, and quality. TV products are no exception. Today's TV products have bid farewell to "price wars" and come to "quality warfare." In order to enhance the picture quality of TVs, manufacturers have adopted "18 martial arts" one after another. Among them, the struggle between OLED and QLED is the most talked about.
But this year, Sharp, which has returned to the Chinese market, has launched the world's first consumer-grade 8K TV. The powerful 8K technology will also become the "number one rival" for OLEDs and QLEDs. It will rise with excellent screen display and a complete ecological chain. Which of these three types of TV display technology can better capture the user's favor? Take the author for analysis.
OLED is the future display technology? The market is promising but the sales are not good Let's first look at the OLED technology in the three major technologies. OLED, which is an organic light emitting diode, does not require a backlight layer when emitting light, and can perform self-luminescence. OLED TVs only need a very thin OLED coating and glass substrate, and they can emit light under the action of current. It is for this reason that OLED TVs have certain advantages in contrast and color. Because it does not need to go through multiple layers of filters, it can obtain more pure colors.
Despite these advantages, OLED TVs are currently a "looks beautiful" concept for many consumers. Although the self-luminous characteristics allow it to have advantages in terms of color, etc., panels made of organic materials actually have hidden service life problems. With the passage of time, organic materials in OLEDs will continue to oxidize and ultimately affect the picture effects of television. At the same time, the "half-life" inherent in OLED materials has also caused other problems. Just a few days ago, Apple admitted that brightness degradation, screen color cast, image sticking and other OLED burning phenomenon can not be completely avoided, can only minimize the probability, it is this problem is to limit the OLED TV replacement cycle Longer appliance application. Another major problem affecting the sales volume of OLED TVs is the price. Due to the current high price of OLED panels, the price of TV is not close to the public. In addition, OLED panel technology has not yet been fully developed, and the issue of low panel yields still exists. For a variety of reasons, although OLEDs seem to be powerful, they have not achieved true penetration in popularity.
Powerful rivals of the QLED camp: Under the propaganda, there are hidden defects. In recent years, there has also emerged another panel technology that competes with OLEDs, QLEDs. Current QLED TVs incorporate a quantum dot coating on the backlight, and the nanoscale quantum dots of different radiuses are illuminated by light sources. This light-emitting principle makes the color purity of the QLED TV stronger, and the color reproduction degree is also stronger. After placing the quantum dot optical material between the backlight and the panel, under the effect of the blue light source, a fairly accurate bright color can be obtained, and the color gamut coverage is close to that of the OLED television.
Although the appearance of QLED TV has made many people see another possibility of TV development, today's QLED is not a "complete body." In fact, the current "QLED" TV on the market should be called QD-LCD Quantum Dot TV. True QLED TVs do not require a backlight, and the light emission principle is similar to that of OLED TVs, which control the quantum dot emission through current stimulation. However, current QD TVs still need backlight sources, so LCD TVs still suffer from defects such as light leakage, low contrast, and poor viewing angle. The most deadly problem of QD-LCD TVs lies in the raw materials of quantum dots. Most of the quantum dot materials used in this type of television are harmful. If they are used, they will have a great impact on the human body and may even cause cancer. In 2016, the European Union banned the import of Quantum Dot TV. Although there are vendors that promise quantum dots TVs, it also shows that TVs have sacrificed higher color performance and have actually discounted their value. With respect to OLED TVs, the price of quantum dot TVs is also quite expensive. It is twice as high as similar products and also restricts its development to some extent.
8K will usher in the mature period of technology and industrial chain advantages. According to statistics, in the offline market in the first half of this year, the penetration rate of QLED QD TV was 1.7%, an increase of 0.7% over the same period of last year; while in the omnichannel, the OLED market penetration rate It was 0.2%, an increase of 0.1% over the same period last year. From the point of view of the data, although the two "played a buzz", they did not "see the truth." There are various types of defects in technology, price, service life, and use safety. OLEDs and QLEDs cannot yet be completely overcome. Compared with the first two types of technologies, 8K technology becomes more mature. Not only does the technology already have related standards, but under the impetus of Sharp, the industrial chain is further improved. The environment suitable for development also makes 8K one of the most popular technologies today. What is the appeal of 8K TV? Let us know something together.
8K resolution, that is 7680*4320 resolution, pixel can reach 33 million. The 8K resolution is 4 times that of the current 4K TV and 16 times that of the 1080P. From the point of view of definition, it can reach quite a shock level. The author once experienced the effect of 8K TV. Sharp 8K TV can fully display all the details. At the same time, 8K TV sets are also stipulated on the frame rate of the picture, which needs to reach 120 frames per second, which is very close to the human eye's reflection speed, allowing the viewer to obtain a sense of real immersion. With a frame of up to 33 million pixels per second of 120 frames, enough to "cheat" your eyes. At the same time, the minimum color depth for 8K TVs is 12 bits. The depth of color parameter, which determines how many colors each pixel can use at a resolution, is expressed. The higher the color depth, the more colors the screen can ultimately present. Reflected in the picture, high-color TVs may display more colorful and beautiful pictures, which is one of the advantages of 8K in picture quality.
In terms of standards, there are currently super high-definition television standards such as the SHV (SUPER HIGH VISION) standard, and 8K resolution is also required to ensure the quality and sound quality of 8K resolution. At the same time, Sharp also learned the 4K technology experience in the promotion of 8K technology, and merged it from the upstream and downstream of the industrial chain to further improve the industrial chain. Sharp provides 8K technology for shooting and editing equipment in terms of content, editing, transmission, and display. With the coming of the 5G era, with the speed of 5G transmission, 8K TVs will not be subject to transmission restrictions. In the future, Sharp will also build 8 life scenes based on 8K, covering work, education, entertainment, family social networking, safety, health, property transactions, environmental protection cars, and many other aspects, allowing 8K to truly enter the lives of consumers. Therefore, no matter from the angle of technology or the integrity of the industry chain, 8K technology has already gained considerable advantages under Sharp's promotion, and will also gain consumer recognition in the next competition.
Nowadays, the features of high-end and large-screen TVs have further manifested, and 4K resolution has no greater ability to enhance the picture quality. The emergence and popularity of 8K is an inevitable result of TV development. Sharp is using 8K as an entry point to integrate big screens into every corner of life and promote the development of intelligent life.

The 8-inch tablet will have a big impact on the 7-inch and 10-inch tablet market. Because the portability of an 8-inch tablet is stronger than that of a 10-inch tablet, and the usable area is larger than that of a 7-inch tablet. The most important thing is that the price is more moderate, which is much cheaper than a 10-inch tablet. It can be said that the 8-inch tablet computer has a good balance between portability and screen display area, and is more likely to be favored by the majority of users.
