I have a question for you: What type of technology that isn’t visible, but is important for smartphones, tablets and other mobile devices. The answer is the multi-touch screens, which have triggered the explosive growth of the mobile device market. And thanks to the industrial touch screen PC in Thailand, these has all been made possible.
Not so many years by, we had to use our thumbs to input on a micro-keyboard of a Blackberry or used to touch a PalmPilot with small stylus. But since January 2007, everything changed, especially with the innovation of Apple iPhones. Suddenly, many use their fingers to touch the screen, to pinch the images and perform various controls that haven’t been part of a smart phone interface.
Touching Many Paths
To start with, not all touches are created equal. Touch technologies can differ depending on the design engineers. According to a touch industry expert, there are about 18 distinctive touch technologies available in the market. Some use force sensors; some use sound waves; while others use infrared light. All of them have their own benefits and drawbacks, including size, reliability, accuracy, durability, the touches sensed, and the price.
As it turns out, there are two technologies now being used in the market for displayinga screen in a mobile device. The two approaches have distinctive features, with one requiring moving parts, while the other is solid state. One depends on electrical capacitance, while the other on electrical resistance to sense touches. One is digital and the other is analog. Their distinctive features present the various experiences that end users will venture. This is due to the industrial touch screen PC in Thailand during the innovation phase.
The Touch Screen
The customary touch screen technology is resistive to analog. It opposes electricity, so it can pass through a material. The panels work by discovering a resistance to present modifications once the point is touched.
Analog voltages are processed by analog to digital converters to innovate a digital signal that a device controller can use as an input signal from the user. Thanks to the industrial touch screen PC in Thailand, such innovation has been designed and programmed to suit user’s specific needs.
