Explore our industrial-grade resistive and capacitive touch assemblies designed to perform under demanding environments.
In modern industrial and commercial operations, human-machine interface (HMI) configurations demand an optimal balance of viewability, responsive control, and structural durability. The 15-inch form factor—spanning traditional 4:3 configurations and modern 15.6-inch widescreen designs—has established itself as the global industry benchmark. This dimension provides enough canvas for complex user interface layouts, multi-layered parameter monitoring, and virtual touch-key pads, all while maintaining a compact physical footprint that integrates into standard control panels, standard racks, and kiosk enclosures.
As industries shift toward IoT-enabled automation (Industry 4.0), the requirements for custom touchscreens have transitioned from basic pressure sensitivity to advanced Projected Capacitive (PCAP) multi-touch capabilities. OEMs and systems integrators are no longer looking for standardized off-the-shelf consumer screens. Instead, they require tailor-made solutions designed for precise environmental hazards: electrical noise from variable frequency drives, water splashes during sterile washdowns, heavy vibrations on maritime vessels, and optical distortion under direct sunlight.
Advanced controller tuning and ITO design patterns suppress high-frequency electrical noise from motors and high-voltage power lines nearby.
Chemically strengthened cover glass (IK08-IK10 rating) prevents impact cracking and surface scratching in unmanned public kiosks.
Built with wide-temperature components, these touchscreens operate reliably across high thermal gradients from -30°C to +85°C.

Led by our dedicated R&D department, we hold multiple utility and invention patents, earning us the designation of a high-tech enterprise of Guangdong Province in 2022.
Custom 15-inch touchscreens play a critical role in complex hardware systems. Off-the-shelf displays fail because they are not designed for varying environmental factors. Below are key applications showing how our touch screens are engineered for demanding real-world conditions:
Our touchscreens feature medical-grade glass designed for frequent sterile chemical washdowns (isopropyl alcohol, hydrogen peroxide). They support multi-finger glove tracking (latex, nitrile, neoprene) and prevent false triggers from liquid droplets on the surface.
Designed for industrial automation, our units run on specialized controller ICs (EETI or Ilitek) that implement proprietary frequency-hopping algorithms. This ensures precise touch registry, even in areas with severe electromagnetic interference (EMI) from heavy motors or welders.
For outdoor kiosks, marine bridges, and remote terminals, we provide optical bonding (OCR/OCA) that eliminates the air gap between the LCD panel and the cover glass. This structure removes internal reflection, boosts sunlight readability by up to 300%, and prevents moisture condensation.
When specifying custom 15-inch touch panels, choosing the right material stack is essential for balancing costs and field lifetime. Our R&D department works with developers to optimize every layer of the touchscreen assembly:
We provide chemical and mechanical glass customization directly in our dust-free facility:
We design custom sensor matrices optimized for performance and space constraints:
Guangzhou Xiangrui Optoelectronics is a certified supplier to aerospace, defense, and medical markets, where lifecycle management is critical. We ensure that our custom 15-inch touch panels comply with global regulations and offer long product availability:
Technical guidance to assist hardware engineers and sourcing managers during project specification stages.
Air bonding attaches the touch screen to the LCD using double-sided adhesive tape along the outer borders, leaving an air gap between them. Optical bonding fills this gap with a clear liquid adhesive (LOCA) or optical gel sheet (OCA). This process improves structural strength, eliminates condensation, and enhances readability under direct sunlight by reducing light refraction at internal glass boundaries.
We program specialized controller ICs (EETI/Ilitek) using custom firmware tuning that distinguishes between large static liquid puddles (which are ignored) and localized finger inputs. We also offer hydrophobic (AF) cover glass coatings that bead water away, preventing moisture build-up from disrupting the sensor grid.
Yes, we provide full cover glass customization. We offer thicknesses from 0.7mm to over 10mm (for high-impact Vandal-Proof IK10 applications). We also support customized edge profiling (2.5D curved borders), screen printing in custom colors, and physical cutouts for mechanical buttons, status LEDs, and cameras.
USB is a plug-and-play interface supported by Windows and Linux systems, making it ideal for kiosks and standard industrial computers. For custom embedded systems (ARM, MCU board architectures), I2C is preferred due to low power consumption and direct system-level integration. RS232 is typically used for legacy installations where long cable runs are required.
For extreme environments, we build touch screen stacks with high-temperature ITO films and wide-temperature liquid crystals that operate from -30°C to +85°C. Additionally, we integrate UV-blocking films into the lamination stack to protect the polarizer and OCA layer from yellowing under prolonged solar radiation.
