What! The United States also has high-speed rail?
According to an Associated Press report on April 22, the first real high-speed rail "Western Bright Line" in the United States officially started. According to the builder, the railway will connect Los Angeles, California, and Las Vegas, Nevada, with a total length of 351 kilometers, a total cost of 12 billion US dollars, and a speed of more than 300 kilometers per hour, and is scheduled to be completed before the Los Angeles Olympics in 2028.
On the same day, U.S. Secretary of Transportation Buttigieg lamented that people have been dreaming of high-speed rail in the United States for decades, and this time it has finally come true.
Although it was the first high-speed rail in the United States, it was more than ten years later than China.
At the beginning, China and the United States began to plan the construction of high-speed rail at the same time, but after many years, the United States has not achieved anything, while China has built more than 40,000 kilometers of high-speed rail network. No way, who made us infrastructure madmen.
In addition, China has many technologies that are at the forefront of the United States and even the world, such as new energy vehicles are exported to the European and American markets, and some time ago surpassed Japan and became the largest automobile exporter.
For the Samsung screen that has always monopolized the high-end market in the display field, it has also been terminated by TCL's "Chinese screen". At present, many brands of high-end mobile phones use TCL's Huaxing screen, and even Samsung, Sony and other Japanese and Korean brands are rushing to buy, which shows how popular this screen is in the market.
The reason why TCL spent a huge amount of money to establish TCL Huaxing Optoelectronics and create this top screen is mainly to change China's shortcomings in the field of display in the early days. With years of independent research and development, TCL has formed a complete and mature industrial chain, and has built an ecological advantage that runs through the upstream and downstream industrial chain in the field of Mini LED.
With such advantages, a number of products launched by TCL have achieved outstanding results in the market. For example, the flagship Q10H launched last year hit a new high of 20W+ sales on a certain east platform, and the praise rate was maintained at 99%. Now, as an upgraded iteration of the Q10K and other new products are also officially on sale today, it also brings TCL's new self-developed HVA wide-angle low-reflection screen.
It is understood,This screen has7000:1Native contrast ratio,While greatly improving the light control performance,It also makes the dark effect of the TV better,It will not be gray in the dark night scene,It can be described as the best partner of Mini LED。 In addition, it is also an important part of TCL's global halo control technology, which can solve the halo problem that stumps the entire industry from the whole link of Mini LED imaging.
The main reason why the halo problem can stump the entire industry is that the TV backlight spills out from the brighter area to the surrounding dark area, affecting the area that should be dark or non-luminous. And the larger the backlight zone and the higher the peak brightness, the more difficult it is to control the halo.
In this regard, this technology first improves the light control ability through the six-crystal square core II and super-concentrating microlens. Then, let the macro OD value HVA wide-angle low-reflection screen play a key role. The OD value refers to the distance from the backlight board to the diffuser board, and the Q10K has made this value a small level, so that the light-emitting surface is more focused, and the size of the planned partition is more matched, thus solving the halo problem, and the body is also thinner.
In addition, in this upgrade, the Q10K is also equipped with 2592 backlight partitions and XDR 3800nits peak brightness, which can make dark night scenes deep and not gray, presenting extremely high clarity, rich light and dark details, and richer and more vivid visual effects.
At present, China does have many technologies that have been at the forefront of the world, which is inseparable from the unremitting efforts of the country and even enterprises, such as TCL's achievements in the field of Mini LED, which is the result of its deep cultivation and a lot of hard work. Today, TCL already has a strong Mini LED product matrix, like the latest Q10K, which is equipped with a variety of TCL's self-developed black technologies, which can solve the problem of light control while bringing a viewing experience comparable to that of a professional theater.
