Application scenarios of industrial LCD resistive touch screens

Industrial LCD resistive touchscreens, with their unique technological advantages, are widely used in various industrial scenarios. Resistive touchscreens achieve touch operation through pressure sensing and support touch with any object, including fingers, gloves, and styluses, making them perform excellently in harsh environments. The following are their main applicable scenarios:

Industrial Control

PLC Control Panel

Resistive touchscreens serve as the interface for PLCs (Programmable Logic Controllers), facilitating equipment control and parameter settings for operators.

HMI (Human Machine Interface)

In industrial automated production lines, resistive touchscreens function as HMI devices, clearly displaying production processes and equipment status for real-time monitoring and adjustments by operators.

Medical Equipment

Medical Monitoring Equipment: In the medical field, resistive touchscreens can be used as the operating interface for medical monitoring equipment. Medical personnel can operate the equipment while wearing gloves, ensuring sterility and ease of operation.

Outdoor Equipment

Outdoor Information Kiosks: In outdoor information kiosks, resistive touchscreens can withstand harsh environments such as dust and rain, providing users with stable information retrieval and interactive services.

Production Line Operation

Food and Beverage Bottling Lines

In food and beverage bottling lines, resistive touchscreens can be used to control equipment start-up and shutdown and adjust parameters, offering significant advantages in terms of low cost and ease of maintenance.

Textile Printing and Dyeing Production Lines

In textile printing and dyeing production lines, resistive touchscreens meet the needs of workers for simple operation while reducing equipment procurement and maintenance costs for enterprises.

Other Application Scenarios

Mining

In heavy industrial manufacturing scenarios such as mining, resistive touchscreens demonstrate strong environmental adaptability, ensuring safe production.

Low-cost POS machines and ATMs

Due to their low cost, resistive touchscreens are commonly used in POS machines, ATMs, and other similar equipment.

Technical Principles

Resistive Touchscreens consist of two conductive films separated by tiny insulating dots. When a user presses the screen with their finger or stylus, the two conductive films make contact, and the controller determines the touch position by measuring the voltage change.

Cost Advantages

Resistive touchscreen technology is mature and relatively inexpensive, making it suitable for industrial applications with limited budgets.

Selection Recommendations

When choosing an industrial touchscreen, factors such as the operating environment, touch requirements, and budget should be considered based on the specific application scenario. If the operating environment is harsh, the budget is limited, and multi-touch functionality is not required, a resistive touchscreen is a more suitable choice.

Frequently Asked Questions(FAQ)

What is the lifespan of an industrial LCD resistive touchscreen?

The lifespan of a resistive touchscreen is typically 1 million clicks. However, the actual lifespan will vary depending on usage frequency and operating environment.

Does a resistive touchscreen support multi-touch?

Resistive touchscreens typically only support single-touch, with a few 5-wire resistive screens supporting two-touch.

Can a resistive touchscreen operate stably in harsh environments?

Resistive touchscreens have strong resistance to dirt and scratches, and can operate stably in harsh environments such as humidity, oil, and dust.

What is the light transmittance of a resistive touchscreen?

The light transmittance of resistive touchscreens is relatively low, generally between 75% and 85%. This may result in slightly poorer display quality, but it is usually sufficient for industrial applications.

Does a resistive touchscreen support operation with gloves?

Resistive touchscreens support operation with gloves, which gives them a significant advantage in industrial environments where gloves are required.

Conclusion

Industrial LCD resistive touchscreens, with their unique technological advantages such as support for glove operation, stain and scratch resistance, and lower cost, are widely applicable in various industrial scenarios, including industrial control, medical equipment, outdoor information kiosks, and production line operations. While their single-point touch and low light transmittance limit some applications, their stability and cost-effectiveness in harsh environments make them the preferred choice for many industrial applications. When selecting an industrial touchscreen, a comprehensive evaluation based on specific application requirements and budget is essential; resistive touchscreens are undoubtedly a reliable choice for meeting specific industrial needs.
