Principle of Operation of Resistive Touch Panels

Resistive touch panels, which are visually similar, are different solutions characterized not only by their operating principle but also by factors such as sensitivity, precision, resistance to damage, and light transmittance. Touch panels are a universal term used to refer to the combination of displays, touch sensors, and glass. In our offering, we consistently provide two types of touch sensors: resistive (RTP) and capacitive (CTP) touch panels. Upon request, we can also provide solutions using other technologies, such as IR (infrared). Below, we provide a characterization of resistive touch panels.

Characteristics of Resistive Touch Panels

Resistive touch panels operate based on the principle of detecting changes in resistance. They consist of two layers: a flexible top layer and a rigid bottom layer. Both layers are coated with layers of indium tin oxide (ITO) on their inner surfaces. When the screen is touched, the top and bottom layers come into physical contact, resulting in a point of contact and a change in resistance. This change in resistance is measured and processed into a touch point by the controller. Resistive touch panels offer certain advantages, such as the ability to operate with any object (not limited to conductive objects) and the ability to function even with gloved hands. However, they may have lower sensitivity and require more pressure compared to capacitive touch panels. It's important to consider the specific requirements and intended use of the touch panel when selecting between resistive and capacitive options.
