Looking for a Capacitive Touch Screen manufacturer

Capacitive touch screen technology works by using the human body’s current sensing. The capacitive touch screen is a four-layer composite glass screen. The inner surface and the interlayer of the glass screen are each coated with a layer of ITO. The outermost layer is a thin layer of silica glass protective layer. The interlayer ITO coating is used as the working surface. Four electrodes, the inner layer of ITO is a shielding layer to ensure a good working environment. When a finger touches the metal layer, a coupling capacitance is formed between the user and the touch screen surface due to the electric field of the human body. For high-frequency current, the capacitance is a direct conductor, so the finger draws a small current from the contact point. This current flows out from the electrodes on the four corners of the touch screen respectively, and the current flowing through these four electrodes is proportional to the distance from the finger to the four corners. The controller obtains the position of the touch point by accurately calculating the ratio of the four currents.

 

 

Throughout the past century, technology has improved in many ways. The way in which humans interact with technology is one of the most important ways technology is changing. By using touch screen technology, the user is able to manipulate a digital environment by only the touch of their finger, or another input device, on the screen. This report discusses the different technologies that make this possible: infrared, resistive, and capacitive touch screens, as well as their qualities in modern devices.

 

Touch screen technology first entered the public eye in 1971, with the invention of the Elograph, by Elographics, Inc. This company was created to “produce Graphical Data Digitizers for use in research and industrial applications” [1]. This technology set the stage for many devices to come. One of the next devices to be invented was the HP-150, the first touch screen computer. Hewlett Packard invented this device in 1983. This technology is important because it “had infrared touch-screen capability, allowing for creation of ATM (Automated Teller Machine)-like applications”. These are two of the most important devices in the development of touch screen technology. As time progressed, touch screen devices have become increasingly more complex and sustainable, providing the user with greater accuracy and more features to improve the quality of life.

 

The touchscreen has two main attributes. First, it enables one to interact directly with what is displayed, rather than indirectly with a pointer controlled by a mouse or touchpad. Secondly, it lets one do so without requiring any intermediate device that would need to be held in the hand (other than a stylus, which is optional for most modern touchscreens). Such displays can be attached to computers, or to networks as terminals. They also play a prominent role in the design of digital appliances such as the satellite navigation devices, palmtop computer, mobile phones, and video games etc.
