The capacitive touch key panel was only seen in the hi-end products like Hd Tv, computer monitor and kitchen appliance before. Now many companies are active to integrate the touch technology into the total stock series. Habitancy will find the capative touch technology has been widely used in the Samsung buyer electronics products line. The touch key can not only heighten the aesthetic and commercial design, but also the reliability, because the captive touch key will not be worn for frequent operation.
With the addition acceptance of the market, the touch key switch products has been extended to vent fan, electromagnetic oven, water heater, microwave oven, blood-pressure meter, transported Dvd player, notebook and even Tv.
Piezoelectric Pressure Sensor
With the addition of the touch application market, touch Ic has come to be the developing direction of many Mcu manufacturers. The cost of the capacitive key is lower than the piezoelectric type. It's more advantageous than the resistance-type on the reliability and cost of the exterior material. It's generally because the capacitive type uses the single Ito Glass structure. Without Ito Film, it has nice carrying out on the transparency and assistance life.
What's the touch Tv? It's undoubtedly the touch Tv remote. All the present plastic keys are changed to touch type. The human-computer interface will come to be beautiful. What's the expectation of the product? It will be tested by the market.
No matter the dishwasher, blu-ray disc player or smartphone builder will face many competitors and it's hard to diverse the products on the function and specification. The elegant, absorbing and direct user interface can come to be the key factor to generate the critical buyer products. The capacitive touch is obviously the foremost technology motor to help the builder perceive the goal.
The household appliances, 3C and buyer electronics are the main target shop of the touch key application. Shengyang started to arrange the touch Ic shop since it launches the first generation touch switch chip stock in 2007. The main representative stock is an eight bit control Ic Ht46R73D-3 with built-in Touch-key function. It's very suitable for the bridge type sensor measuring principles products like bathroom scale, pressure gauge, hygrometer and tire gauge.
For separate application market, the touch Ic technology is differently required. For the transported products, the power-saving, low absorbing and ageement features are the main demands. But for car and medical products, the stability and reliability come to be the main demands.
Compared with the touch screen which is popular in the movable phone field, the most unavoidable feature of touch key is the low cost. The touch screen requires more of Ic found than the key application. In the technology exploring process, the cost becomes one of the factors which will impede the development.
With the promoting of the vertical integration of the industry, the touch Ic found firm will begin to cooperate with the panel firm to shorten the developing period and low the cost. And finally in the capacitive key field, the transparent capacitive keys will be increasingly used on the monitor.
