Inherit all the advantages of high-temperature process 5-wire resistive products, and are more durable.

For harsh temperature environments, or environments with high or low pressure, Glass-Film-Glass resistive products have higher tolerance.

The hardness of glass surface is as high as 7H, which can increase resisting stain and wear.

The glass can enhance its optical effect for various applications needs, to achieve low reflection and high penetration

Operating Principle & Structure

We also called it the GFG resistive touch panel is made of a very thin layer of optical glass bonded to the surface of the resistive product with OCA. It has the advantages of glass, and it combines the principle of resistive touch panel. The analog signal will be converted into a digital signal by the controller, and then the correct position of the touch will be calculated by the computer.


GFG resistive touch panels are widely used in aerospace, military, shipbuilding, industrial control, agriculture, food processing, construction and other fields, we guarantee continuous supply for 5-10 years. We have a comprehensive supply chain system for the high-end application. After long-term material testing and verification, we ensure the products that we provide to our customers can meet the requirements of industry standards.

Customized Enhanced Product (Optional)

In order to meet the requirements of high performance, our five-wire resistive touch panel can be produced with following enhanced technologies to meet the needs of the high-end market.

Optical Coatings on mirco-glass surface

According to application requirements, additional optical coatings such as AG, AR, AS coatings are available to be supplied on the surface of micro-glass.

Wide Temperature Range Technology

For the extremely harsh environment of low temperature to high temperature (ex: -30℃~80℃), it can effectively control the variability of appearance and maintain the operation of the product, which can keep the product with stable and high performance.

Long Lifetime Design

For applications requiring high touch durability, we can provide solution for up to 35 million finger clicks times (at the same point), and has passed strict click tests to ensure product durability.

EMI Shielding Design

To meet high-end market needs, such as military standard applications, we can provide professional EMI shielding solutions.

UV Resistant Design

For outdoor application requirements, long-term exposure to the UV environment may cause potential damage to the surface or the coating of the touch panel, which might affect the appearance and the function of it. UV-resistant design can effectively reduce the issue caused by UV exposure.

Vandal Proof Design

To meet safety regulation requirements, products with vandal proof design are provided. The glass substrate of the touch panel must meet the vandal proof specification when it is broken. Ensuring that the fragments will not splash out and injure people when the glass is cracked.

Heating Design

In cold areas many products are often used in low-temperature environment, resulting in poor performance and low reliability. Providing products with heating designs can effectively improve issues caused by low-temperature environments and allow products to operate successfully.

Optical Requirement Design
According to some specific optical application, we can use these solutions to achieve clear vision, low reflections, and high penetration.
