Touch technology for industrial LCD screens: capacitive vs. resistive

 

In the field of industrial LCD screens, touch technology is the key to improving operational convenience and efficiency. Capacitive and resistive touch technologies are the two main touch methods, each with its own advantages and disadvantages, and are suitable for different industrial application scenarios.

 

Capacitive touch technology:

Capacitive touch screens use the capacitance characteristics of the human body to detect the touch position. When a finger touches the screen, the capacitive sensor on the screen detects the change in capacitance to determine the touch position. Capacitive touch screens have the following advantages:

High precision: It can achieve high-precision touch positioning, which is suitable for scenarios that require precise operation.

Multi-touch: It supports multi-touch and can recognize multiple touch points at the same time, which is suitable for complex operations and gesture recognition.

Fast response speed: The touch response time is short and the operation is smoother.

High durability: The surface is usually covered with a layer of glass or reinforced plastic, which has high durability and scratch resistance.


Resistive touch technology:

Resistive touch screens detect touch position through pressure changes. When a finger or stylus presses the screen, the upper and lower conductive layers of the screen come into contact to form a circuit, thereby determining the touch location. Resistive touch screens have the following advantages:

Low cost: The manufacturing cost is relatively low, suitable for cost-sensitive application scenarios.

Supports a variety of touch tools: Not only can it be operated with fingers, but also with styluses or other conductive objects, suitable for scenarios that require precise writing.

Strong environmental adaptability: Strong adaptability to environmental humidity and temperature, suitable for use in harsh environments.
