Capacitive sensing technology into the embedded touch technology Character LCD Modules

Reduce the thickness of the touch panel, In-cell action device is thin and light experience. Capacitive sensing technology has undergone significant evolution since its publication, not only to achieve multi-finger touch, to interpret a variety of complex gestures, better able to respond to flooding the environment of the source of interference, as well as support for large-size screen. Today, the industry has been actively involved in the Embedded (In-cell) technology research and development period to further reduce the thickness of the touch panel and cost.custom lcd

Which touch function has entered into the tablet computer this new type of mobile device used in the tablet computer touch capacitive sensing technology will continue to drive this wave of technology wave. From home appliances to automotive, industrial, residential automation, action and family operations, capacitive sensing technology is affecting the interaction between the user and electronic devices.
Capacitive sensing technology has experienced for the first time since the publication of a substantial evolution, the beginning is just a simple button technology, mainly used to track the the finger X and Y axis coordinates of the location, and then evolved into simultaneously track multiple fingers position. Today, these devices are able to track the number of fingers has no upper limit, and can be interpreted a variety of more complex gestures, payable flooded sources of interference environment and support for larger screen sizes. Next objective is to reduce the cost, the various manufacturers i.e. carried the embedded formula (In-cell) technology development.Character LCD Modules
Capacitive touch sensor technology complex
Capacitive sensing technology does not like to buy a silicon chip mounted to a printed circuit board (PCB) is as simple as in the use of electronic means. Capacitive sensing is a complex electro-mechanical systems, which often includes several major parts of the overlying lenses (Cover Lens), sensors, soft flat cable (Flex Tail) and chips, together make up the touch system.
Analysis of such a stack, to exclude inherently requires the upper glass or screen, the system is the most expensive part is the sensor itself. Since the sensor is not easy to manufacture, requires a plurality of process steps and a laminated film, and the material used is also very expensive, so the cost of such a sensor is three times the chip in the phone application, and the proportion of its cost and the size of the screen into instead is proportional to the length of the diagonal screen.
