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.
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.
Changes in the cell phone case
sliding phone
folding phone
rotating phone
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
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 phones Nokia
3210
Nokia 3210 which can
be double-sided shed
its shell and built-in
antenna new models
launched in 1999.
Internal components
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.
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 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.
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 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 highdefinition era Mobile phone screen is into hd
1080p era

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.
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.
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.
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.
Internal components
Axis accelerometer and gyroscope

The Coriolis force
generated when the
chip contains a micromagnetic 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.
