Used in various fields of integrated capacitive touch solution – capacitance, the solution – the electronics industry
Capacitor Touch controllers have been widely used in a variety of products areas, including mobile phones, and even home appliances. The workshop will introduce you to the application of capacitive touch solutions integration model trends and best solution for capacitive touch applications.
In this seminar you will learn:
* Leadis has capacitive touch controller products into the characteristics and functions
* Different capacitive touch sensing methods and their respective advantages and disadvantages and the challenges
* Successful application of the best cases of capacitive touch technology
Q: Can you give a specific capacitive touch controller used in home appliances or mobile phones in the instance of it?
A: Capacitance touch control applications in the mobile above is very broad, you may recall LG Chocolate mobile phone to do, to do is capacitive touch buttons, if entered, the button will be activated will also light a red LED Light, Samsung recently introduced a slider phone called the 1908, below the main screen, there is a small screen, the surface of the small screen with touch sensor technology is the controller to do so in the mobile market, we can see a lot of capacitive sensors in the product, while in the home appliance category, you may see some touch of the control panel, the top equipment in the industry will see a lot, so this capacitive touch controller application is very now extensive.
Q: capacitive touch technology is now the touch screen of the most advanced technology?
A: The touch buttons on the touch screen area actually is not the latest technology, about 4 years ago already, and now in the market above, you can see many different location, such as mobile phones, microwave ovens, washing machines, etc. These buttons can be to replace the traditional keypad, most manufacturers are using this approach to replace the traditional keypad.
Q: How accurate positioning without interference, resulting in miscarriage of justice?
A: On the sources of interference, including Battery , Temperature, humidity, etc., for temperature, humidity, our IC with automatic tuning system that can automatically adjust for battery wave microwave, we are through different PCB The wiring guide to achieve anti-jamming means.
Q: If the PCB substrate moisture will not affect the operation?
A: PCB damp humidity environment that is affected, of course, our IC controller with automatic calibration function can automatically correct the temperature, the PCB substrate is damp affect operations, but also the material of the PCB to consider.
Q: can not use gloves, touch pen can not be used, whether there are other tools that can replace the touch of a finger when it is not changes in capacitance value range is very small, can not find things to do produce similar changes in capacitance ?
A: If a finger touches it, Power supply Value change is the biggest, of course, if using gloves or other hand-written document, then, will the changes become smaller, increased sensitivity, so it is necessary finger touch judge touch response, if it is now in the market above, there are some applications In the special capacitive touch pen, above which the conductivity of intelligent fingers spread above the stylus to change the capacitance characteristics, so this is a relative of the program to achieve.
Q: dim feature, you can individually control each LED?
A: dim function can control the LED's, each road can be a separate control of LED current size, including the option to use as LED lights, which are individually controlled.
