Explore our high-performance standard and custom small-to-large-format touch modules engineered for challenging operating environments.
Founded in 2010 in Guangzhou, China, Guangzhou Xiangrui Optoelectronics Technology Co., Ltd. has established itself as an industry-leading manufacturer specializing in the research, development, production, and distribution of resistive touch panels, projected capacitive (PCAP) touch screens, customized cover glass, and complete liquid crystal module (LCM) optical bonding solutions.
Over the past decade, we have scaled our operations to support specialized industrial-grade and consumer electronics touch integrations globally. Guided by a core mission focused on technological innovation, manufacturing excellence, and compliance with the most stringent global standards, we provide both standard models and bespoke OEM/ODM design paths.
Our company is ISO 9001 and ISO 14001 certified. Our factory floor houses modern cleanrooms matching class 100, class 1000, and class 10000 cleanliness configurations, allowing us to perform critical optical bonding processes with absolute minimal particulates.
An authoritative guide to projected capacitive and resistive architectures, materials selection, and factory integration protocols.
Large-format 32-inch capacitive touch panels utilize advanced sensor designs with high channel counts. We utilize high-tier IC chips (such as EETI, ILITEK, and SIS) to maintain high signal-to-noise ratios (SNR), supporting glove input, multi-touch precision (up to 10/40 points), and performance in high-humidity or high-ESD settings.
For interactive applications, cover glass durability is crucial. We offer soda-lime glass, chemically strengthened Corning Gorilla Glass, and AGC Dragontrail glass. Surface options include Anti-Glare (AG), Anti-Reflective (AR), and Anti-Fingerprint (AF) chemical vapor deposition coatings.
Our cleanrooms support optical bonding (LOCA/OCR) directly between the 32-inch touch sensor and the LCD matrix. Eliminating the air gap reduces internal reflections by up to 90%, improves sunlight readability, increases impact resistance, and prevents condensation buildup.
Touch sensor manufacturing requires high environmental cleanliness. Our facility houses three cleanroom classes designed to prevent microscopic debris from compromising optical clarity:
Each batch undergoes strict testing, including climate-chamber aging, drop tests, mechanical wear checks, and high-frequency noise exposure, ensuring consistent performance in demanding applications.
Why global OEMs partner with Guangzhou Xiangrui for customized touch technology solutions.
We control the complete pipeline from raw cover glass cutting and screen printing to sensor lamination, FPC customization, and final optical bonding. This minimizes logistics transit times and reduces structural defect rates.
Located in Guangzhou's electronics manufacturing zone, we have immediate access to specialized glass foundries, controller IC supply lanes, and international shipping channels out of Nansha or Hong Kong ports.
Whether you require specialized glass shape profiles, physical camera holes, custom silk-screened logos, or custom FPC tail lengths and pinouts, our engineering department designs tailored solutions within 5-10 business days.
Integrating a large-format 32-inch touch screen panel requires international regulatory alignment. At Guangzhou Xiangrui, we support our global partners with compliance documentation:
Before finalizing your 32-inch touch panel order, ensure your supplier meets the following parameters:

Technological shifts shaping the design and manufacturing of large-format touch displays.
The market for 32-inch and larger touch panels is shifting toward ultra-thin borders, flexible sensors, and integrated display-touch modules (TDDI). We invest heavily in R&D to incorporate these emerging technologies into our standard catalog.
Metal mesh sensors are increasingly replacing standard Indium Tin Oxide (ITO) for large-format displays. This technology offers lower sheet resistance, reducing latency and improving sensitivity in sizes over 32 inches.
We are also expanding production of smart-home control glass panels featuring integrated dead-front printing. This treatment allows graphical indicators to remain invisible until backlit, offering a clean aesthetic.
