Yunfu mobile phone touch screen measuring instrument manufacturer, preferred billion-Photoelectric

Yunfu mobile phone touch screen measuring instrument manufacturer, preferred billion-Photoelectric Billion mobile phone manufacturing gauge constant touch higher, newer, more requirements, such as requiring faster, better stability, detecting even micro damage non-destructive, remote sensing remote control more distance, more convenient, no pollution, but also for the development of mobile phone touch screen measuring instrument science and industry provides a powerful impetus. At the same time, the company has been recognized as the national high-tech enterprises, private technology enterprises in Guangdong Province, private technology enterprises in Dongguan City, Dongguan City, Quality and Technical Supervision under the Dongguan Association executive director units of measurement, Dongguan City Network Chamber of Commerce governing units. Touch screen: The touch screen is used on our mobile phones is one of them. There are many types of touch screen products, mainly divided into: capacitive screen, resistive screen, voltage touch screen, infrared touch screen, surface acoustic wave touch screens. Many phones are now mainly used capacitive touch screen, capacitive screen constituted by the four composite glass screen, where the screen surface and laminated glass are coated with a layer of ITO, etc., which is configured here is not explained in detail. Its working principle is: when we use capacitive screen, since the human body is a conductor, and the electric field, when before the finger touches the screen, the finger and the screen to form a coupling capacitor, low current finger on the touch screen will be sucked screen, touch screen changes in current can cause changes in the signal. Yunfu mobile phone touch screen measuring instrument manufacturer, preferred billion-Photoelectric Dongguan City billion-Photoelectric Technology Co., Ltd. was established in 2003, is a collection of sophisticated detection equipment research and development, production and sales of high-tech enterprises. The company's main products are: Image measuring instrument, optical projector series, coordinate measuring machine series, tool microscope series, grating sensor series, tensile testing machine, environmental testing machine series nearly 100 kinds of detection equipment.
