Capacitive screens and resistive screens are two common touchscreen technologies. There are some differences between them in terms of working principles, touch experiences, and application scenarios. The following will introduce their characteristics and distinctions in detail.

I. Working Principles

1. Capacitive Screens: Capacitive screens operate based on the principle of capacitance. The screen surface is covered with a layer of conductive material. When a finger touches the screen, the weak electric current carried by the human body causes a change in the electric field on the screen surface. The capacitive screen determines the touch position by detecting this change in the electric field.

2. Resistive Screens: Resistive screens work on the principle of resistance. There is a layer of resistive material on the top of the screen and another layer on the bottom, with a tiny gap separating the two layers. When the touchscreen is pressed, the two layers come into contact, and the touch position is determined by measuring the change in resistance at the contact point.

II. Touch Experiences

1. Sensitivity: Capacitive screens have relatively high sensitivity and can achieve multi-touch, supporting gestures such as finger sliding, zooming in and out. In contrast, resistive screens have relatively low sensitivity and can only support single-touch.

2. Accuracy: Capacitive screens offer higher touch accuracy and can accurately identify the coordinate positions of touch points. Resistive screens, on the other hand, have relatively lower touch accuracy and may have certain errors.

3. Transparency: Capacitive screens have higher transparency, and touching does not affect the screen display effect. Resistive screens have relatively lower transparency, and there may be some obstruction when touched.

III. Application Scenarios

1. Capacitive Screens: With high sensitivity and touch accuracy, capacitive screens are suitable for scenarios that require frequent touch operations or multi-touch, such as smartphones, tablets, and car navigation systems.

2. Resistive Screens: Resistive screens are relatively inexpensive and durable, making them suitable for scenarios where high touch accuracy is not required, such as industrial control devices, cash registers, and ATMs.

IV. Comparison of Advantages and Disadvantages

1. Advantages of Capacitive Screens:

   • High sensitivity, providing a good touch experience.

   • Support for multi-touch, enabling more flexible operations.

   • Touching does not affect the screen display effect.

2. Disadvantages of Capacive Screens:

   • Higher cost.

   • Require special capacitive materials for manufacturing.

3. Advantages of Resistive Screens:

   • Relatively low price.

   • Good durability and are not easily damaged.

4. Disadvantages of Resistive Screens:

   • Relatively low sensitivity and touch accuracy.

   • Only capable of single-touch.

In conclusion, there are certain differences between capacitive screens and resistive screens in terms of working principles, touch experiences, and application scenarios. The choice of which touchscreen technology to use depends on actual needs and budget.
