And something else... About capacitive touchscreens ... Are you curious?
Capacitive touchscreens (like the iPhone) are a touchscreen variant of the
no pressure
is required for operation. This is because it is an electrical field that is built up over four corners and has a uniform voltage. With a finger or a conductive object changes this field and sensors can detect where the contact is taking place.
The capacitive touchscreens: their conception is very different from that of the resistive monitors, although both systems have similarities. As with the models above, this technology also relies on a touch-sensitive layer on the surface of the monitor.
How does this work?
How a capacitive touch screen works How a capacitive touch screen works
In this case, the glass surface of the monitor is provided with a conductive layer, which usually consists of indium tin oxide (ITO). This material is transparent to a very low thickness. This layer is connected to electrodes located on the edges of the monitor. In this way, a uniform electric field is created on the surface of the monitor. In other words: the surface is charged evenly. When a finger approaches this electric field, some of the charge jumps over to the finger. This disturbance is then perceived by the control of the monitor.
The ITO layer was attached to the outside of the first capacitive touchscreens. It therefore wore out quickly, which limited the life of the product. Nowadays, the algorithms for touch recognition are so advanced that a greater distance between the ITO layer and the finger is possible. The surface of the monitor now consists only of simple glass. So wear and tear is no longer an issue.
Not even the ultimate
The main advantage of capacitive touchscreens is the much less reduced brightness of the monitor. The low thickness of the conductive layer ensures a high level of transparency (over 90%). They also offer excellent resolution. And the control module is particularly compact. However, they are still much more expensive than resistive touchscreens.
