Since the launch of the iPhone in 2007, Apple has been called "the industry's subversive." Of course, this is indeed the case. iPhone sets off a new trend for large-screen smart phones; iPad makes tablet computers "resurrection";
Watch is not the first wearable device to be released, but it successfully connects fashion and technology to make wearable devices truly acceptable. It also has the Macbook series's declining trend in reverse PC sales, making it the only bright spot in the notebook market. . However, I always feel that there are shortcomings. If I insist on picking faults with Apple, it is always a smart TV that has been constantly exposed to news.
Every time Apple's new conference, the public are looking forward to the hope that Apple can redefine smart TV. However, according to the Wall Street Journal, Apple had shelved the HDTV plan as early as a year ago, and Apple has been preparing this product for almost 10 years. Think about it again, Apple already has the natural conditions of forming a closed television loop, whether it is port, content, App or smart home systems, etc., are already ready to go. Suddenly giving up means that ten years of swords are empty.
For Apple, although there is a tradition of constantly changing everything, it can be seen that whether it is a smart phone, a tablet or a smart watch, the starting point is at the mobile level, focusing on the future, leading the new trend, not In the rescue of those "incorrigible", immobile, slow-moving products and even the growth of the Macbook is still only updated step by step, and no revolutionary change.
Therefore, although Apple's smart TV program has been prepared for 10 years and has also allowed the industry to look forward to 10 years, according to Apple's ability to predict the pace of the future, it is clear that the potential of smart TV has been clearly estimated. The fact is also true. With the rise of mobile intelligent terminal devices, the operating rate of smart TVs has decreased. Although it is the largest "one screen" in the life of the general public, the importance of it has been declining again and again. This trend is even more pronounced after young people become the main consumers.
In addition, it should be noted that Apple has opened up multiple fronts to different mobile smart terminals. If you rush to introduce smart TV products, although there is a certain probability to get a lot of money, but it may be because of too much distraction, lack of concentration, resulting in smart TV products become a supporting role, and finally become a short-board Apple TV dragging its own performance The current status of the box is enough. For Apple, it is naturally impossible to fall into an unknown situation under the current excellent situation.
The display has become elbow, Apple is difficult to get
Relatively mobile smart terminals are more dependent on the system used, and the most important criterion for distinguishing smart TVs is whether they are good or not. Do not look at Apple in the so-called supply chain to shake the wind, so that all suppliers turn around it, but in the large-size display there is no advantage. In addition, Apple's largest screen hardware product, the iMac all-in-one, is constantly exposed to the problem of "grey spots," making fruit powder prohibitive.
While smart TV displays are often more than 50 inches, and are basically monopolized by Samsung, LG, Sony and other manufacturers, Apple itself does not have much technical accumulation. Although Apple and Samsung still have a huge amount of cooperation on the processor, but also have a business relationship with the LG, but basically are involved in the field of mobile smart terminals Apple's momentum is irresistible, they can not make any criticism of Apple in these areas.
However, in the field of smart TVs, Samsung, LG, etc. are among the top manufacturers in the world, and they already have their own monopoly advantages. Of course, they do not want Apple to come in. If that is the case, Samsung, LG, etc. are really working for Apple and the main weapon in their hands is the large-size display. With huge production lines accumulated over many years, they do not speak, and Apple cannot have a presence in the smart TV market. As a result.
Farewell, difficult-to-produce Apple Smart TV
Whenever the news of Apple's smart TV broke out on the Internet, I always smiled. After all, the development and introduction of a new product is far more complicated, difficult and changeable than it was supposed to be. Perhaps in the past few years, Apple also introduced the appearance of smart TV, but as the times continue to evolve, Apple has long since broken the mind.
Uncertainly, the gradual decline in the sales of iPads for large-size mobile devices has already given Apple a wake-up call. As the sales of the iPhone have increased, Watch has become the new force. Smart TVs are becoming more and more dispensable. Therefore, Apple's smart TV must have been "abortion". Therefore, let us drool on the online renderings. No, TV.

3000W Three Phase AC Source System
Product Introduction:
APM 3 Phase Ac source SPS300VAC3000W is capable of delivering 3000VA of output power.3 Phase Ac Power Source is a 3-phase output programmable AC Power Supply which provides with high power density. With high speed DSP+CPLD control, high frequency PWM technology, active PFC design, It is able to provide not only stable DC/AC output power, but also 3-phase / 1-phase output. This AC power supply is featured with high power density, high reliability and high precision, meanwhile it possesses operation interface of touch screen and keys manually. It is able to analog output normal or abnormal power input for electrical device to meet test requirements, which is applicable to electric, lighting, aviation sectors, etc. It could be applied to enterprise`s production test as well.
