Over all
 This concept is also a core value of our existing products,
which make people feel more happy. Our focus is to sleep and
wake up. The main idea of the product is like a lamp. You can
adjust the sound, lighting. And it has a natural mode is set.
Available in the rain on the sunny sea, for example, Rain mode;
You can hear the rain on the rain and can smell of rain, etc
Enginearing knowledge
>> Touch screen system
 Screen Resistive
Resistive Touch Screen is composed of a flexible layer on top.
The bottom layer is a hard surface. The center has been insulated,
which serves to separate it from the inside of the second contact
layer. Because the inside of the second layer is coated with
transparent conductors are in the current release of the conductor
layer. When you press the Touch Screen to make a second layer to
the next. Then, the control circuit calculates the cost of electricity. This
will vary depending on the position of contact.
Advantages
Affordable, Can use other objects touch it, Find locates resolution,
Low power consumption
Disadvantages
Must be calibrated frequently, Damage caused by sharp objects easily
 Screen Capacitive
Touch Screen Capacitive structure consists of a glass plate coated with a transparent metal
oxide. When it's time to have the input voltage across the four corners of the Touch Screen to
create uniform electric field intensity throughout the piece.
Users will need to use your fingers touch the screen to the
current from each corner to keep the pressure on the
screen. Then, the control circuit calculates a touch position
Advantages
Definition, Light from the screen to pass out. Resulting in
clearer images, Can touch with your fingers
Disadvantages
The sensitivity of the device will be worse when the
interference from electronic noise, The price is quite high, a
lot of energy, Problems with the external light.
Next Week Job
We must conclude function of the product into block
