1. Project Overview: An Integrated Industrial Touch Display Solution

In industrial control, intelligent equipment, and professional display applications, a display module must do more than deliver clear visual output. It also needs to support reliable touch interaction, mechanical protection, interface compatibility, and convenient system integration.

DINGTouch has completed a new 18.5-inch high-brightness industrial touch display customization project, integrating an AUO industrial LCD, a customized capacitive touch sensor, chemically strengthened cover glass, full optical bonding, and an HDMI-to-eDP display driver solution.

The project uses the AUO G185HAN01.4 LCD, featuring Full HD resolution and 1800-nit brightness. The touch system reuses DINGTouch existing capacitive touch sensor and USB interface, supporting 10-point multi-touch.

The customized cover glass features 2mm chemically strengthened glass, AG AF surface treatment, and black silk-screen printing. The LCD, touch sensor, and cover glass are integrated through full optical bonding.

To simplify host-system integration, the project also incorporates an HDMI-to-eDP converter board with PWM brightness control, 12V DC power input, and a customized cable with a minimum length of 300mm.

Rather than simply combining an LCD and a touchscreen, DINGTouch developed an integrated display assembly covering display performance, touch functionality, cover glass protection, optical bonding, signal conversion, and power requirements.

This project demonstrates DINGTouch capability to deliver customized industrial touch display solutions based on mature display platforms and application-specific integration requirements.

2. Project Specifications: 18.5-Inch FHD High-Brightness Touch Display

The project combines a mature AUO LCD platform with customized touch, cover glass, optical bonding, and display driver integration.

Project focus: Integrating a high-brightness LCD, an existing capacitive touch platform, customized cover glass, full optical bonding, and an HDMI-to-eDP driver solution into a complete industrial touch display assembly.

3. 1800-Nit High-Brightness LCD: Improved Visibility for Industrial Applications

The display core of this project is the AUO G185HAN01.4 LCD.

With an 18.5-inch screen size and 1920 × 1080 Full HD resolution, the display provides a large viewing area and detailed image output for industrial equipment and professional applications.

The project adopts an 1800-nit high-brightness configuration to meet applications requiring enhanced display visibility under challenging lighting conditions.

Industrial displays may operate in environments with strong ambient light, overhead lighting, or changing illumination conditions. In these situations, display brightness becomes an important factor in maintaining visual clarity.

However, actual display visibility depends on more than the LCD nominal brightness.

Cover glass transmission, surface reflection, optical bonding, viewing conditions, and installation environment all influence the final visual performance.

By combining a high-brightness LCD with a full optical bonding structure, DINGTouch optimizes the overall display assembly for the project's intended application.

4. 10-Point Capacitive Touch: Reusing a Mature Sensor Platform

The touch system uses DINGTouch existing customized capacitive touch sensor and USB touch interface.

The solution supports 10-point multi-touch, providing flexibility for industrial interfaces, multi-finger interaction, and application-specific user interface designs.

The key touch integration considerations include:

• Existing sensor platform: Reuses a mature DINGTouch touch sensor to reduce unnecessary redevelopment.

• USB touch interface: Provides a convenient connection between the touch system and the host device.

• 10-point multi-touch: Supports multi-finger interaction and advanced interface operations.

• Customized cover glass: Matches the touch sensor to the 2mm chemically strengthened glass and black silk-screen design.

• Full optical bonding: Integrates the cover glass, touch sensor, and LCD into a complete display assembly.

In industrial touch display applications, touch performance depends not only on the sensor itself but also on cover glass thickness, sensor design, controller configuration, and the surrounding electromagnetic environment.

For this reason, DINGTouch evaluates the touch sensor, cover glass, and bonding structure together rather than treating them as independent components.

This integrated approach helps establish a more suitable touch configuration for the customer's equipment.

5. Customized Cover Glass: 2mm Chemically Strengthened Glass with AG AF and Black Printing

Cover glass is an important component of an industrial touch display, providing mechanical protection, surface functionality, and customized appearance.

This project adopts 2mm chemically strengthened glass with AG AF surface treatment and black silk-screen printing.

5.1 Chemically Strengthened Glass: Protection and Structural Integration

Chemically strengthened glass is processed through ion exchange, creating a surface compressive stress layer that can improve its mechanical strength and resistance to damage.

The project uses 2mm chemically strengthened glass to provide protection while meeting the customer's structural requirements.

Actual mechanical performance depends on the glass material, strengthening process, edge finishing, mounting structure, and application conditions.

Therefore, the final reliability requirements should be evaluated through project-specific testing.

5.2 AG Surface Treatment: Reducing Environmental Reflection

AG stands for Anti-Glare.

Anti-glare treatment modifies the glass surface to reduce specular reflection and improve visual comfort under certain lighting conditions.

Industrial equipment may be exposed to overhead lighting, surrounding light sources, and other environmental reflections.

AG treatment can help improve display visibility in these conditions.

However, its effectiveness depends on surface texture, gloss level, image clarity, and the actual lighting environment.

The appropriate AG configuration should therefore be selected according to the customer's display requirements.

5.3 AF Surface Treatment: Improving Fingerprint Resistance

AF stands for Anti-Fingerprint.

AF treatment typically uses a low-surface-energy coating to reduce fingerprint adhesion and improve surface cleaning.

For industrial equipment with frequent touch interaction, this treatment can help maintain a cleaner appearance and reduce visible fingerprint residue.

5.4 Black Silk-Screen Printing: Customized Appearance and Display Integration

The project incorporates black silk-screen printing on the cover glass.

Black printing can help define the non-display area, conceal selected internal components, and create a more consistent visual boundary between the display assembly and the equipment enclosure.

By integrating chemically strengthened glass, AG AF surface treatment, and black printing, DINGTouch combines mechanical protection, surface functionality, and customized appearance in one cover glass design.

6. Full Optical Bonding: Optimizing the LCD and Touch Assembly

The project adopts full optical bonding to integrate the cover glass, capacitive touch sensor, and LCD.

In conventional air-gap structures, the interfaces between display components can introduce additional reflections that affect visual performance under certain lighting conditions.

Full optical bonding reduces the air gap between the components and creates a more integrated optical structure.

The main benefits of this project-specific bonding configuration include:

• Reducing reflections associated with the air gap between the cover glass and display.

• Improving overall visual performance under high-brightness operating conditions.

• Increasing the structural integration of the display assembly.

• Reducing the impact of internal air gaps on the viewing experience.

• Integrating the customized cover glass, touch sensor, and LCD into one assembly.

For an 1800-nit high-brightness display, optical bonding is an important part of the overall optical design.

The bonding material, process parameters, and reliability requirements must be evaluated according to the actual display structure and operating environment.

DINGTouch integrates these considerations into the customized display development process.

7. HDMI-to-eDP Driver Integration: Signal Conversion and Brightness Control

The LCD in this project uses an eDP display interface, while the customer's system requires HDMI video input.

To meet this requirement, DINGTouch integrates an HDMI-to-eDP converter board to connect the host's HDMI output with the LCD eDP interface.

7.1 HDMI Input and eDP Display Output

The HDMI-to-eDP solution enables the customer to connect an HDMI video source to the customized display assembly.

This approach simplifies display interface adaptation and reduces the need for the customer to develop a dedicated eDP output solution on the host system.

Supported resolution, refresh rate, timing configuration, and compatibility must be verified against the converter board design and LCD requirements.

7.2 PWM Brightness Control

The project driver solution supports PWM brightness adjustment.

PWM stands for Pulse Width Modulation.

By adjusting the duty cycle of the control signal, PWM can regulate the LCD backlight brightness.

For high-brightness industrial displays, brightness adjustment allows the equipment to adapt the display output to different operating conditions and user requirements.

The implementation of PWM control depends on the driver board design and the LCD backlight requirements.

7.3 12V DC Power Input and Customized Cable

The project uses a 12V DC power input and includes a customized connection cable with a minimum length of 300mm.

By integrating power, display signal conversion, and brightness control into the driver solution, DINGTouch simplifies the connection between the display assembly and the customer's host system.

Integration focus: HDMI video input, eDP LCD output, PWM brightness adjustment, and 12V DC power supply within one customized driver solution.

8. Project Innovation: From Individual Components to an Integrated Touch Display

The value of this project lies not only in selecting an 18.5-inch high-brightness LCD but also in coordinating multiple technical components within one display assembly.

Innovation 1: Integrating a Mature Touch Platform into a New Display Structure

The project reuses DINGTouch existing capacitive touch sensor and USB interface.

This approach preserves the established touch platform while integrating it with the 18.5-inch LCD and customized cover glass.

Innovation 2: Combining High-Brightness Display and Full Optical Bonding

The 1800-nit LCD is integrated with a full optical bonding structure to optimize the overall optical configuration for industrial display applications.

Innovation 3: Integrating Cover Glass Protection and Surface Functionality

The 2mm chemically strengthened glass incorporates AG AF surface treatment and black silk-screen printing.

This combines mechanical protection, surface functionality, and customized appearance in one glass component.

Innovation 4: Integrating HDMI and eDP Display Interfaces

The HDMI-to-eDP driver solution supports the customer's host interface requirements while incorporating PWM brightness adjustment and 12V DC power input.

Innovation 5: Customized Integration of Display, Touch, Glass, and Driver Components

LCD, touch sensor, cover glass, optical bonding, and driver electronics are developed as one integrated display solution.

This reduces the customer's need to separately source and integrate multiple components.
