The original of the phoneThe original of the phone

1.The concept of mobile phones in 1985, Bell Labs to create the first so-called mobile to large2.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.

The first cell phones The first cell phones Motorola DynaTacMotorola 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.

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 thecustomers

What is WAP?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..

No antenna cell phonesNo antenna cell phones Nokia 3210Nokia 3210

Nokia 3210 which can be double-sided shed its shell and built-in antenna new models launched in 1999.

Bluetooth phonesBluetooth 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.

What is Bluetooth?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

Global Positioning Global Positioning SystemSystem

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.

The development of the The development of the mobile phone monitormobile 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 16000000 with the clear image and made a forward in the world

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

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.

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.

Capacitive 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.

Optical (infrared) touch panel

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.

Electromagnetic touch panels

Internal components

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.
