Weekly Progress

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.

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.
