Comment choisir entre écrans résistifs et capacitifs pour Panel PC industriel embarqué?

Le type d’écran est un élément important à prendre en compte lors du choix d’un Panel PC industriel embarqué. Les écrans résistifs et capacitifs sont les deux technologies tactiles les plus courantes, chacun avec des caractéristiques et des scénarios d’application différents.

Un écran résistif est un type d’écran qui réalise un fonctionnement tactile grâce à la détection de pression, and users only need to apply pressure with their fingers, gloves, stylus, or other hard objects to operate. Its main features include:

Multiple input methods: Resistive screens can support finger, stylus, and even glove operation, making them suitable for use in environments that require multiple input methods, such as factory floors or harsh outdoor environments.

Relatively low cost: Compared to capacitive screens, resistive screens are relatively inexpensive, making them an economical choice for projects or applications with limited budgets.

Strong anti-interference ability: Since resistive screens rely on physical pressure to recognize touch signals, they are not easily affected by water, poussière, or oil, making them suitable for use in more complex environmental scenarios.

Capacitive screen is through the human body's electrostatic induction to recognize the touch operation, usually using a finger directly in contact with the screen can be operated. The main advantages of capacitive screens include:

High sensitivity: Capacitive screens are very responsive to touch actions, making the user experience smoother and suitable for application scenarios that require precise control and fast response.

Multi-touch: Capacitive screens support multi-touch, which enables more gestures, which is very favorable for application scenarios that require higher interactivity (such as sales displays or medical devices).

Strong durability: The surface of capacitive screens is usually made of hard glass, which is wear-resistant and scratch-resistant, and has a relatively long service life.

When choosing an embedded industrial panel PC, resistive and capacitive screens have their own advantages and disadvantages, and the key is to combine the use of scenarios and budget to make a decision. For customers who need to use in harsh environments and have a limited budget, resistive screens may be a more appropriate choice. In the case of limited budget, the cost advantage of resistive screen should not be ignored. En même temps, it is also important to consider the cost-effectiveness of long-term use, such as maintenance costs and replacement cycles.

Although OAI only provides embedded industrial panel PCs with capacitive screens currently, we are always committed to providing practical products and services to our customers. We are constantly keeping an eye on market demand and plan to introduce more touchscreen options in the future to better serve various application scenarios. Stay tuned!
