Development history
In the late 1960s, AlanKay of Xerox Palo Alto Research Center put forward the concept of "Dynabook". He imagines that it is a computer that can be carried around, and its main function is to help children learn. In order to develop Dynabook, Allen even invented the Smalltalk programming language and developed a graphical user interface, which is the embryonic form of Apple Macintosh. However, due to various objective reasons, the center does not support this idea.
1September 1989, GRiD Systems successfully manufactured the first commercial tablet computer and named it GRiD Pad. Its operating system is based on MS-DOS.
It can be said that from the late 1960s to the late 1990s, tablet computers were still in the initial exploration stage. Due to the limitation of hardware technology such as core chips, tablet computers are only popularized and used in a small range. Real commercialization should start with Microsoft. NET strategy conference in the new millennium.
In June, 2000, Microsoft first showed off a tablet computer that was still in the development stage. NET strategy ". In June 2000, 165438+ 10, at Comdex Fall 2000, one of the three major computer exhibitions in the world, Mr. Gates gave a special speech on TabletPC, and defined Tablet PC as "all-around PC based on Windows operating system". On June 8th, 2002, 65438+February 8th, 2002, Microsoft officially released TabletPC Edition and its special operating system Windows XP in new york, which marked that the tablet PC officially entered the commercial sales stage.
On the other hand, on 20 10, 654381October 27th, the rumored first-generation iPad was also unveiled. Of course, the concepts of Pad and tablet are very different.
2011September, with the release of Microsoft Windows 8 system, the tablet camp expanded again.
On June 2012 19, Microsoft released the Surface tablet in Los Angeles, USA. The product is divided into two versions: Surface RT adopts Windows RT operating system, and CPU is quad-core NVIDIA Tegra 3；; ; The Chinese version/professional version of Surface is pre-installed with Windows 8, and the CPU uses the third-generation Intel Core i5 processor. Since the Surface can be connected to an external keyboard, Microsoft claims that this tablet can easily become a "full desktop PC" after being connected to the keyboard. It is not difficult to see from the parameters of the two Surface that the core indicators such as CPU have been greatly improved, especially the improvement of the processor. The latest technology can provide strong support for the performance of tablet computers, enhance the characteristics, security and management of graphics cards, and make tablet computers faster and consume less power. Among them, the third-generation Intel Core processor adopts 22 nm process technology and the world's first new transistor technology with 3D architecture. The switching speed is increased by 37%, the power consumption is reduced by about 50%, and the graphics card function is greatly improved to help various commercial demonstrations.
At the 20 13 information technology summit (IDF), Ian Yang, Intel's global vice president and general manager in China, said that there are more and more products equipped with Intel processors, besides the common all-in-one machines, notebooks and ultrabooks, there are also tablets, mobile phones and various embedded systems. The functions of these products are changing with each passing day, and more and more advanced technologies are applied to practical products, such as touch, somatosensory interaction and facial recognition. Shi Haode, general manager of Intel's PC client division, said that Intel is about to release the fourth generation Intel Core processor series, which has been shipped to OEM customers and will be released at the end of the second quarter. Ultrabooks based on the 4th generation Intel Core processor series will bring exciting new computing experience and all-day battery life to consumers, achieving the most significant battery life improvement in Intel's history. Through the deformable and pluggable ultrabook system, it will also bring consumers a new round of "two in one" trend. In the amazing new device form, consumers can get a full-featured PC experience and the best tablet experience at the same time.
Internationally, the focus of the global flat panel display industry is shifting to China. In order to continue to seize the China market, overseas enterprises gradually changed their original strategy of refusing to export technology to China, and began to compete with local enterprises by investing in factories and setting up production bases in China. In this case, we should be alert to the situation that foreign enterprises transfer backward production capacity and get rid of their burdens.
Since 20 13, foreign enterprises have further opened up in the field of flat panel display, relaxed the restrictions on China's export production lines and technologies, and strengthened market expansion through cooperation with domestic panel, material and equipment enterprises. At the same time, the transfer of production capacity of advanced countries and regions to China will inevitably bring some impacts to domestic enterprises. Therefore, it is particularly important to adopt the correct way of strategic cooperation and competition.
From the domestic factors, China's flat panel display industry has entered a stage of rapid development, but a large number of key materials and equipment are imported from abroad, which is obviously different from foreign countries. It is predicted that in 20 13 years, China will continue to increase its policy support for key materials and equipment, and the supporting capacity of flat panel display products is expected to be improved, and its dependence on foreign imports will be reduced. It is predicted that in 20 13 years, domestic flat panel display enterprises will still be at a disadvantage in the competition of new display technologies, especially AMOLED, new backplane technology (LTPS, Ox ide) and ultra-high resolution display technology. With the expiration of the policy of "20 10~20 12 flat panel display industry development plan", whether or not to introduce new industrial incentive policies will directly affect the motivation of technological innovation and product innovation of enterprises.

For a time, from the upstream to the terminal, from the operating system to the software application, an ecological chain of tablet computer industry has formed, and the ecological chain of tablet computer industry has developed rapidly. In 20 10, the sales of PCs in China reached 48.583 million units, an increase of 16. 1% compared with 2009, among which the sales of tablet PCs reached 1.74 million units, accounting for about 3.58%. With the rapid development of tablet computers, the position of tablet computers in the PC industry will become more and more important, and the proportion in the PC industry will also increase. Judging from the international market, it is estimated that the global tablet market will reach 49 billion US dollars in 20 15 years. From the industrial development stage, in the three years from 20 10 to 20 12, tablet computers will go through the stage from birth to maturity, and the whole industry will show a rapid upward trend. During this period, the industrial development direction, market scale, industry pattern and consumer demand are not clear, and there are many market opportunities, and new brands will appear in every link of the industrial chain. Among them, hardware terminal equipment, service content provision and peripheral supporting equipment will be more concentrated and obvious.
operating system
Operating system (OS) is a computer program that manages computer software and hardware resources, and it is also the kernel and cornerstone of a computer system. The operating system needs to deal with basic affairs such as managing and configuring memory, determining the priority of supply and demand of system resources, controlling input and output devices, operating networks, and managing file systems. The operating system also provides an operating interface for users to interact with the system. The most common operating systems are Windows operating system, Android operating system and iOS operating system, as well as Windows CE operating system. In addition, Meego and Moblin, as Intel's products mainly for mobile phones and MID markets, are likely to appear on tablet platforms in the future, as well as WebOS, which is called the inevitable product of cloud computing.
