3. The original of the phone
1.The concept of mobile phones in 1985, Bell Labs to create the first so-called mobile to large
2.In 1946, before the birth of the first modern sense, the real mobile phone. It is the power and the antenna is placed in a box, weighing about three kilograms, very heavy and inconvenient, the user should be carrying it like a backpack as walking, so I was called a shoulder phone.

4. The first cell phones Motorola DynaTac
1983 the world's first mobile phone Motorola DynaTAC 8000X weighs 2 pounds and a half hours of talk time, sales prices of $ 3,995, is truly the most precious bricks.

5. Changes in the cell phone case
folding phone
sliding phone
rotating phone

6. Changes in phone functions
The first has the Wireless Application Protocol (WAP) mobile phone nokia 7110
The WEB server specified by the client to the URL request is sent
to the WEB server based on the requesting program to return the appropriate content to the client, both interact HTTP protocol. but they are in HTML format the corresponding returned to the
customers

7. What is WAP?
WAP network architecture consists of three parts, between the GSM network and the World Wide Web; WAP content server stores a lot of information to provide WAP mobile phone users to access, query, browse, etc..

8. No antenna cell phones Nokia 3210
Nokia 3210 which can be double-sided shed its shell and built-in antenna new models launched in 1999.

9. Internal components

10. Bluetooth phones
Bluetooth is a short-range radio frequency technology, the device through the chip to communicate with each other without going through the cable transmission.
Advantage：
Available and the range of ten centimeters to 100 meters. To use frequency hopping spread spectrum technology Supports up to eight ports.

11. What is Bluetooth?
As long as the support Bluetooth devices with each other can exchange data, regardless of the mobile phone in the bag, "Bluetooth" plans to construct personalized wireless LAN within the range of 10 to 100 meters, can accommodate a minimum of eight small network

12. Picture cell phones Sharp J-sh04
Picture phone inside

13. Global Positioning System
How to use gps?
Satellite continuously send its own the ephemeris parameter and time information, and are calculated by the three-dimensional position of the receiver, the 3D direction as well as the movement speed and time information.

14. The development of the mobile phone monitor
1.material
(1)STN：the first STN screen is small in power consumption and energy saving but with picture contrast and blur red image, low visibility
(2)TFT：TFT screen is with clear picture, smooth screen and pretty color but the power consumption of mobile is rather fast
(3)IPS：Definition,visibility,and color unprecedented is developed very fast and it saves more power
2.COLOR：
It is from 256 to with the clear image and made a forward in the world

15. 3.Mobile phone screen
(1)3 inch screen：we can only see a small fish
(2)4inch screen：we could see penguin can fish
4. resolution ：
You could only see the lattice in the 320*240 screen at the beginning but with the high-definition era Mobile phone screen is into hd 1080p era

17. Newest cell phones Touch panel
Sensor time when the touch of a finger, there will be an analog signal output from the controller to the analog signal is converted to digital signals that the computer can accept, and then via a computer touch driver integration of components compiled by the display card output screen signal on the screen shows the location of the touch.

18. Capacitive touch panel
The capacitive touch panel is substantially improved resistance not scratch characteristics from the outermost layer is a thin layer of silica hardened layer structure, hardness of 7H, the lowermost layer of ITO role as a masking function to maintain the touch Panel interference environment.

19. Optical (infrared) touch panel
Optical touch panel by LED enhance the quality and process of sophistication in recent years comeback, optical touch panel works around the infrared transmitter and receiver, X-axis, and the infrared rays generated by the Y-axis to form a matrix arrangement, wherein the light is blocked by the opaque objects naturally locate the X-axis and Y-axis.

20. Electromagnetic touch panels
The basic principle is by electromagnetic induction, electromagnetic pen signal transmitting end, electromagnetic board signal receiving end, when the proximity sensor flux change by operator defined location point.

21. Internal components
Axis accelerometer and gyroscope
The Coriolis force generated when the chip contains a micro- magnetic body, the rotational movement can be carried out in the mobile phone to the three directions of X, Y, Z displacement, and the direction of movement of the mobile phone can be measured using this principle.
