BiJie is the world’s leading manufacturer of wireless screen projection/wireless display/wireless mirror/wireless screencast products.It can support up to four user projection screens at the same time. It supports such screen projection protocols as Airplay, Miracast, DLNA, WIDI, BJCast and can provide SDK packages.OLED technology, which has been launched in the market for five or six years, may not be unfamiliar to consumers, but according to the sales data over the years, OLED market share is still very low, and it has been overtaken by the rising star QLED. At one time, OLED sold 7 times more than OLED. It is easy to burn screen, short life, high price, size limitation, unable to produce in quantity, and a variety of problems. It’s still a nightmare for OLED. Both internal and external factors confirm the fact that OLED can not unify the new technology of color TV in the future, and QLED is the only way to do it.

Recently, the 3rd 8K QLED Display Technology Forum, hosted by China Electronic Chamber of Commerce, opened in 2019. Many experts in the field of display technology gathered together. The first, two Samsung and TCL in global TV shipments participated in the discussion of the forum deeply. They were firmly optimistic about QLED technology. And the future development forecast of QLED may bring some inspiration to the whole industry.

No matter how good OLED publicity is, it’s better to show it directly.

There is no reason to argue, but the practice is true. The conference site is ingenious. Three contrast tests on QLED and OLED products have been carried out: color contrast, dark field detail/HDR peak brightness contrast and burning screen test.

In the experiment of color contrast, a 4K camera was used to take still life, and the picture was transmitted to QLED TV and OLED TV in real time. From the color effect, QLED TV has a broader color display, closer to the ultimate visual experience of the real world.

In the dark-field detail/HDR peak brightness contrast experiment, a dark-field test room was built at the activity site. In the dark-field environment, the contrast of QLED and OLED dark-field details and HDR peak brightness was tested. The comparison results show that under the same settings of QLED TV and OLED TV, QLED TV can display the dark field details of images normally, and the dark field details of OLED TV pictures are lost, resulting in distortion.

In the burning screen experiment, two machines were booted for a long time at the forum site, and the same picture content was maintained. As a result, QLED TV was displayed normally, while OLED TV pictures appeared "stand-by sign and screen need to be maintained, please stand-by for 10 minutes" and other retention phenomena, resulting in burning screen.

What is worth mentioning is that the burning screen problem frequently occurs in the OLED TV camp. Last May, a burning screen problem occurred in an OLED TV set at Incheon Airport in Korea. Then, the burning screen problem occurred in OLED TV at the famous manufacturer Nanosys Show Station in SID Display Week 2018 (US Display Week). At present, there is no substantive problem in the industry. Solution.

In the same scenario, OLED has a burning screen.

QLED has the advantage of compacting OLED in the display of gamut range, color purity and color durability.

Consumer choices tell everything.

According to IHS data, QLED’s global sales in 2018 reached 2.68 million units, far higher than OLED’s global sales. According to relevant data, QLED sales will still be in the lead in 2019, with an annual expected sales of 4.07 million units and a global sales growth rate of 52%.

In the domestic market, from the annual sales data, QLED TV shows the advantages of rolling for OLED TV. According to Zhongyikang’s monitoring data, the retail sales of QLED TV in 2016 were more than seven times higher than OLED TV; in 2017, the sales of QLED TV reached 950,000 units, approaching one million gateways, while in 2017, the sales of OLED TV reached 113,000 units, only exceeding 100,000 barriers.

It has to be said that the outcome of the battle between QLED and OLED has long been uncertain.

Therefore, TCL in the forum is confident to sign a contract with Suning, Gome, Jingdong and other mainstream sales channels for QLED TV with 13 billion sales orders, accounting for half of the consumption of 8K TV market.

Good technology for promotion wins

According to IHS forecast, UHD TV will break out in 2020, grow to 430,000 in 2019, approach 2 million in 2020, and the fast growth period of 8K is expected to appear in 2022. It will replace 4K products in a large area, especially in the super-large size market, and complete switching quickly. The development of color TV in the future will be in 8K size. The arrival of large screen 8K is undoubtedly an opportunity for QLED to leave OLED, laser and other display technologies behind.

Laser technology can enlarge the size in short distance, but its resolution is not high, and its display color effect is far less than that of ordinary TV. It also needs specific curtain and dark environment support. It is expensive and not suitable for the public household users.

OLED technology, in addition to the shortcomings mentioned in the previous comparative display, is also subject to technical constraints, unable to provide large-scale solutions, and is still far from the realization of 8K mass production.

QLED technology is the only display scheme that supports full size and 8K at present.

"Good technology suitable for promotion will win." Obviously, QLED can carry the development of 8K screen in the future.

Academician Ouyang Zhongcan of the Chinese Academy of Sciences also said at the forum that the UHD display industry has been developing towards high-end. In the field of large-scale display, QD8K can break through the size limitation and has more room for development than other display technologies.

If 8K makes the gap between QLED and OLED begin to widen gradually, the 2018K QLED Display Technology Forum makes a great difference between them.

In view of the great significance of QLED for the development of the industry, at the forum, China Institute of Electronic Technology Standardization, China Electronic Chamber of Commerce, TCL and Samsung jointly launched the upgrade of 8K UHD Display Certification Technical Specification, which will be upgraded from BT.2020 UHD gamut, HDR high dynamic range and HDMI2.1 high-speed transmission and connection in the future. Starting with port and other aspects, upgrade the performance requirements of 8K TV certification in all aspects.

These technological upgrades, undoubtedly another gap, completely blocked OLED in the 8K door!

Under the mainstream tide of 5G+8K+large screen in the future, it is necessary to upgrade not only the clarity of the screen, but also the gamut range of 8K content, the requirement of color restoration, the dynamic range of brightness, and the details of high contrast scenery. All these are to check the "hard power" of display technology. An important link.

Since the birth of QLED, the decline of OLED has become more and more obvious. From 8K, QLED will leave OLED far behind. As Dr. Luo Zhongsheng, General Manager of Nanosys Greater China and Director of Applied Engineering, expressed at the meeting, quantum dots are starting the next generation of resolution revolution, and the 8K era is coming. Quantum dots display brings consumers the ultimate visual experience in three aspects: high definition, high dynamic range (HDR) and realistic color.

TCL has absolute advantages in the development of QLED and 8K technology in China. TCL is not only the first domestic enterprise to launch quantum dot television, but also has the upstream industry resources of Huaxing Radio and TV. In 2018, TCL invested 5.6 billion yuan in research and development. As of May 2019, the number of patent applications worldwide was 61,234. TCL has 822 public patents in the field of quantum dot electroluminescence, ranking second in the world. TCL has the ability of integration of screen, whole machine and service. Under the strategy of AI * IoT, TCL constantly strengthens the technical ability of products in artificial intelligence and Internet of Things. I believe that TCL will bring you sustained surprises.
