What Is a Tablet Computer?

A tablet computer, also called a Tablet Personal Computer (Tablet PC), is a small, portable personal computer that uses a touch screen as a basic input device. It has a touch screen (also called tablet technology) that allows users to work with a stylus or digital pen instead of a traditional keyboard or mouse. Users can input via built-in handwriting recognition, on-screen soft keyboard, voice recognition, or a real keyboard (if equipped with this model).

At the end of the 1960s, Alan Kay from Xerox Palo Alto Research Center proposed the concept of "Dynabook". He imagined it would be a computer that could be run with a main function to help children learn. In order to develop the Dynabook, Allen even invented the Smalltalk programming language and developed a graphical user interface, which is the prototype of the Apple Macintosh computer. However, due to various objective reasons, the center did not support this idea.

In September 1989, GRiD Systems manufactured the first commercial tablet PC 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 preliminary exploration stage. Due to the limitations of hardware technologies such as core chips, tablet PCs were only promoted and used in a small range. Commercialization in the true sense starts with the Millennium Microsoft's .NET strategy conference.

In June 2000, Microsoft demonstrated the Tablet PC that was still under development for the first time at the ".NET Strategy" conference. In November 2000, at the Comdex Fall 2000 in Las Vegas, USA, one of the 3 largest computer shows in the world, Mr. Gates gave a special presentation on Tablet PC, defining TabletPC as "Windows-based all-around PC ". On December 8, 2002, Microsoft officially released the Tablet PC and its dedicated operating system Windows XP Tablet PC Edition in New York, which marked the official entry of the Tablet PC into commercial sales.

On the other hand, on January 27, 2010, the long-rumored first-generation iPad also unveiled the mystery at the Apple Inc. conference held at the American Fang Cao Grass Art Center. Of course, the concept of Pad and Tablet is very different.

In September 2011, with the release of Microsoft's Windows 8 system, the tablet PC camp expanded again.

On June 19, 2012, Microsoft released the Surface tablet in Los Angeles, the product is divided into two versions: Surface RT uses Windows RT operating system, CPU is quad-core NVIDIA Tegra 3; Surface Chinese / Professional Edition is pre-installed with Windows 8. The CPU uses a third-generation Intel Core i5 processor. Because Surface can be connected to a keyboard, Microsoft claims that this tablet can easily become a "full desktop PC" when connected to the keyboard. It is not difficult to see from the parameters of the two Surfaces that the core indexes such as the CPU have been greatly improved, especially the improvement of the processor. The latest technology can be used to provide strong support for the performance of tablet computers, enhance graphics card features, security and Management features to make tablet PCs faster and consume less power. Among them, the third-generation Intel Core processor adopts 22-nanometer process technology and the world's first new 3D-architecture new transistor technology, which improves the switching speed by 37%, reduces power consumption by about 50%, and greatly improves graphics card functions. Demonstration helps.

At the 2013 Information Technology Summit (IDF), Intel s global vice president and general manager of China Yang Xu said that there are more and more products equipped with Intel processors. In addition to common all-in-one computers, notebooks, ultrabooks, and tablets , Mobile phones, and various embedded systems. The functions of these products are changing rapidly. More and more advanced technologies are being applied to actual products. Touch, somatosensory interaction, facial recognition, virtual reality, voice commands, wireless Charging and even long battery life are all driven by computing. Shi Haode, general manager of Intel's PC Client Division, said that Intel's forthcoming fourth-generation Intel Core processor series will be shipped to OEM customers and will be released at the end of the second quarter. Ultrabooks based on the fourth-generation Intel Core processor series will give consumers an exciting new computing experience and full-day battery life, achieving the most significant improvement in battery life in Intel history. Through the deformable and pluggable ultrabook system, it will also bring a new round of "two-in-one" trend to consumers. In the amazing new device form, consumers can get a full-featured PC experience at the same time. And the best tablet experience.

From an international perspective, the development focus of the global flat panel display industry is shifting to China. In order to continue to seize the Chinese market, overseas companies have gradually changed their original strategy of refusing to export technology to China, and have competed with local enterprises by investing in China to set up factories and set up production bases. In this case, we must be alert to the emergence of foreign companies to carry out outdated capacity transfers.

Since 2013, foreign companies have further opened up in the field of flat panel displays, relaxed restrictions on China's output lines and technologies, and strengthened market expansion through cooperation with domestic panel, material and equipment companies. At the same time, the transfer of production capacity from advanced countries and regions to China is bound to bring a certain impact on domestic enterprises. Therefore, how to take the correct strategic cooperation and competition methods is particularly important.

Judging from domestic factors, China's flat panel display industry has entered a stage of rapid development, but key materials and equipment rely heavily on foreign imports, and the gap with foreign countries is obvious. It is expected that in 2013, China will continue to increase its policy support for key materials and equipment.

In 2010, the Apple iPad set off a wave of tablet PCs around the world. In 2010, the growth rate of keyword searches on tablet computers reached 1328%.

An operating system (OS) is a computer program that manages computer hardware and software resources. It is also the kernel and cornerstone of a computer system. The operating system needs to handle basic tasks such as managing and configuring memory, deciding the priority of system resource supply and demand, controlling input and output devices, operating the network, and managing file systems. The operating system also provides an operating interface for users to interact with the system ^[1]

Tablet PCs have distinctive features in appearance. Some are like a separate LCD

1. Because the screen rotation device requires space, the "performance-to-volume ratio" and "performance-to-weight ratio" of a tablet computer are not the same as those of a traditional notebook computer with specifications.

2. Decoding-Programming languages are not good for handwriting recognition.

3. Typing (students writing assignments, writing emails)-handwriting input is too slow compared to typing speeds of up to 30 to 60 words per minute.

4. In addition, a tablet computer (pure tablet type) without a keyboard cannot replace a traditional laptop computer, and it will make users feel more difficult (beginners and experts) to use the computer. (Pure tablet is the second computer that people often use for recording or teaching tools.)

5. The battery is easily damaged

Tablet PCs are increasingly entering the average home. The battery of a tablet computer is a fragile component, and how to maintain it has become the most headache for many users. In this regard, the author consulted some computer repair and maintenance experts and summarized a few tips on tablet computer repair and maintenance.

Charging problem: If the tablet computer is equipped with a docking charger, you should try to use a docking charger as usual. The dock charging has the ability to identify data when charging, and it uses a small current to charge. Although it takes longer than charging (travel charging), this charging will make the battery charge more. At the same time, you should use dedicated sockets as much as possible, and do not share the sockets with chargers and TVs.

It doesn't matter if the battery is turned on: It is best to turn off the tablet first when charging. Because during the charging process, the circuit board of the tablet computer will heat up, which may cause the current to increase instantaneously and cause damage to the internal parts of the tablet computer.

How long is the charging time? The longer the charging time, the more the battery is charged, the more durable the battery is. This view is incorrect. In fact, the capacity of the battery is certain.

Tablet computers are LCD screens with touch recognition, which can be input by hand with an electromagnetic induction pen. The tablet computer integrates mobile commerce, mobile communication and mobile entertainment, and has handwriting recognition and wireless network communication functions. It is called the terminator of netbooks.

According to the structural design, tablet computers can be roughly divided into two types, namely "variable tablet computers with integrated keyboards" and "pure tablet computers" with external keyboards. The tablet computer itself has some new application software built in. Users can enter text or hand-drawn graphics into the computer as long as they write on the screen.

Tablet computers are generally divided into resistive touch screens and capacitive touch screens according to their touch screens. The capacitive touch screen works by using the human body's induced current.

The tablet computer that can make a phone calls through the built-in signal transmission module: wifi signal module, sim card module (ie 3G signal module). Divided into WIFI version and 3G version according to different dialing methods.

In the information society, people mostly get information and log in to various applications (

The latest research report by market research company IDC reveals the global tablet device vendor s device sales in the third quarter: In short, Android tablet sales rose. In fact, analysts believe that Android is the entire tablet market in the third quarter. The main driving force for development. In the third quarter, sales of the entire tablet PC market rose 7% from the previous month and 36.7% from the same period last year.

In the ranking of equipment supplier contributions, Samsung's contribution ranks second. In the third quarter, its sales reached 9.7 million units, accounting for 20.4% of the global market. Nexus 7 maker Asus sold 3.5 million tablets, accounting for 7.4% of the global market.

Tablets in the "Others" category accounted for 35.3% of the global market, down 38.8% year-on-year.

However, in the third quarter, although Apple did not launch any new tablets, it was still the world's largest supplier of tablets. In the quarter, iPad sales reached 14.1 million units, a slight decline from 14.6 million units during the same period. However, Apple's market share was 40.2%, and at the end of the third quarter it was only 30%

However, it must be noted that Apple did not launch a new product until last week. With the iPad Air on sale this Friday and the retina iPad mini launched in November, the sales situation in the fourth quarter will change significantly.

However, despite the rapid development of Android tablets, it is still Apple's world today. "Apple introduced two 7.9-inch tablets starting at $ 299 and $ 399, and two 9.7-inch tablets starting at $ 399 and $ 499, indicating that the company has begun to explore multiple segments It s worth pointing out that Apple is not the only supplier to increase the price of small-sized tablets: Google and Amazon have both raised the price of their latest 7-inch tablets from $ 199 to $ 229 to pay for high-resolution Costs associated with displays and premium processors. "

In the evening news on March 7, 2014, IDC predicts that, as users in developed countries do not consider it necessary to upgrade the high-end tablet computers currently in use, global tablet sales will decline by 32.2% year-on-year.

In 2019, global tablet PC shipments are expected to decline by 8.9% and 8.7% in the second quarter of 2019, which is traditionally still in the off-season. Global tablet PC shipments in the first quarter were 37.15 million units, down 12.9% from the previous quarter, but up 13.8% year-on-year.
