With support for up to 10 simultaneous touch points and a resolution of 32768 × 32768, the TK Series provides precise touch detection for interactive displays, self-service equipment, industrial control interfaces and other touch-enabled systems. Its USB 2.0 full-speed interface supports plug-and-play operation without requiring a separate driver installation.

Key Product Features

1. 10-Point Multi-Touch

The TK Series supports multi-touch operation with up to 10 touch points, allowing users to perform simultaneous touch actions for interactive applications, control interfaces and commercial display systems.

2. High-Resolution Touch Detection

With a touch resolution of 32768 × 32768, the infrared touch screen is designed to provide detailed touch positioning and responsive operation across the active display area.

3. 3mm Tempered Glass Coverage

The screen uses 3mm tempered glass coverage to provide a durable touch surface for environments where the display may experience frequent contact during daily operation.

4. High Ambient Light Resistance

The TK Series is designed to operate with light resistance of up to 80,000 Lux, helping maintain touch performance in applications exposed to strong ambient lighting.

5. USB Plug-and-Play Interface

The USB 2.0 full-speed interface simplifies connection between the touch screen and host equipment. The plug-and-play design allows the system to recognize the touch interface without requiring a separate driver.

6. Long-Life LED Infrared Technology

The infrared receiving tube uses an LED-based design with a stated service life of up to 60,000 hours. The optical components are designed for stable performance during extended operation.

7. Aluminum Alloy Housing

The 8mm-thick aluminum alloy shell provides a compact structure with good mechanical durability. The surface uses a high-temperature black metal powder coating process for a consistent industrial appearance.

8. Integrated Controller

The integrated controller converts infrared touch signals into system input, supporting responsive interaction while simplifying the overall touch-screen structure.

Available Screen Sizes

The TK Series is available in multiple screen sizes and aspect ratios to accommodate different display structures and equipment designs.

• 4:3: 15 inches

• 16:9: 15.6, 18.5, 19, 21.5 and 23.6 inches

• 5:4: 17 and 19 inches

• 16:10: 22 inches

This size range allows equipment manufacturers and system integrators to select a touch screen according to the required display format and installation space.

Touch Screen Structure

The TK infrared touch screen uses a streamlined aluminum alloy frame with a compact structure. The aluminum shell is formed through an industrial aluminum alloy stretching process and finished with high-temperature black metal powder spraying.

The approximately 8mm shell thickness helps maintain a compact installation profile while providing structural support for the infrared touch components. The integrated controller and infrared receiving components are arranged within the touch frame to create a complete touch-input assembly.

The Infrared Touch Screen 15 to 23.6 Inches (TK Series) is therefore suitable for equipment designs where straightforward integration, durable construction and multi-system compatibility are important considerations.

Connection and System Compatibility

The TK Series uses a USB 2.0 full-speed interface with a plug-and-play connection method. After connecting the USB interface to the host device, the touch screen can be recognized by the supported operating system without requiring an additional touch driver.

The series supports:

• Windows

• Android

• Linux

Its driver-layer adaptation allows the touch interface to be integrated into a broad range of mainstream consumer and commercial operating environments.

The USB interface provides a transmission speed of up to 480 Mbps under the USB 2.0 specification, supporting the communication requirements of the touch controller.

Advantages for B2B Applications

Industrial Control

The durable aluminum frame, tempered glass surface and multi-touch capability make the TK Series suitable for industrial control panels, machine interfaces and automation equipment.

Commercial Self-Service

The touch screen can be integrated into self-service terminals, information kiosks and interactive commercial equipment where simple USB connection and reliable touch input are required.

Public Service Equipment

Multiple available sizes and broad system compatibility support integration into public information terminals, interactive service systems and other touch-operated equipment.

Healthcare Equipment

The touch interface can be incorporated into selected healthcare equipment and control terminals requiring a durable glass touch surface and responsive multi-touch input.

Transportation Systems

The TK Series can be used in touch-enabled transportation equipment, information terminals and control interfaces where compact construction and stable touch detection are required.

Installation Method

The TK infrared touch screen is designed for straightforward installation.

1. Open the package and remove the infrared touch screen.

2. Connect the USB interface to the main unit.

3. Check the system interface to confirm that the touch signal is recognized.

4. Apply double-sided adhesive tape to the rear surface as required.

5. Align the touch screen with the display viewing window.

6. Press the touch screen into position and ensure that the adhesive is securely attached.

7. Complete the installation and test the touch function.

Before final installation, the mounting surface and viewing window should be checked for cleanliness, alignment and sufficient contact area.

Application Considerations

When selecting a TK Series infrared touch screen, buyers should consider the following factors:

• Required screen size and aspect ratio

• Display opening and installation dimensions

• Operating system compatibility

• Number of required simultaneous touch points

• Ambient light conditions

• Required glass thickness and surface durability

• USB interface availability

• Installation method and available mounting space

Selecting the appropriate size and aspect ratio according to the host display helps ensure proper mechanical integration.

Product Selection Guide

For compact commercial displays, 15-inch and 15.6-inch models can be considered according to the required aspect ratio. Larger 21.5-inch and 23.6-inch models can provide a larger interactive area for control terminals and self-service equipment.

For systems using Windows, Android or Linux, the driver-free USB interface provides a simplified connection method. Where equipment operates under strong ambient lighting, the specified 80,000 Lux light-resistance capability should also be considered during system design.
