5-wire Resistive Touch Screen

Product description

A 5-wire resistive touch screen is coated with a thin metallic, electrically conductive and resistive layer that causes a change in the electrical current that is registered as a touch event and sent to the controller for processing.
Resistive touch panels are generally more affordable, but offer only 75% clarity and the layer can be damaged by sharp objects.
On the other hand, resistive touch screens are not affected by elements, such as dust or water.
Generally, in the analog resistive technology, the top layer acts as a probe that detects the other axis (X or Y).

However, wearing out the top layer may degrade the linearity and the accuracy of detecting the coordinates.
The 5-wire resistive technology complements such weak points and vulnerabilities.

As shown above, 5-wire technology utilizes the bottom substrate for both the X and Y axes for potential measurements. All the electrodes are placed on the bottom layer and the top layer acts only as a voltage-measuring probe.
This basic design difference of the structure leads to a much more durable and stable characteristics, which allows the screens to work properly even with non-uniformity on the top layer's conductive coating.
Advantages of the INO 5R -Enhanced accuracy, superior performance and durability.
-Finger, gloved hand and pen all possible for data entering.
-Strong resistance to external static electricity and noise in poor conditions -Clean original images by using films with excellent transmission
