São Paulo, the economic engine of Brazil and Latin America, is undergoing an unprecedented wave of technological modernization. From the automotive assembly lines in ABC Paulista to the high-tech manufacturing parks of Campinas, and the cutting-edge medical electronics cluster in São José dos Campos, industries are rapidly transitioning to advanced Human-Machine Interfaces (HMIs). High-performance Capacitive Touch TFT LCD displays are at the center of this transformation, providing the interactive reliability required by modern electronic control units.
As a trusted OEM/ODM manufacturer, Shenzhen Xunrui Optoelectronics Technology Co., Ltd. delivers custom optical and capacitive touch solutions tailored specifically to withstand Brazil’s challenging industrial environments. Whether your equipment operates in high ambient humidity, demands gloved and wet-finger operability, or requires robust Electromagnetic Compatibility (EMC) to handle power grid fluctuations in São Paulo, our technological design philosophy guarantees zero-fail field performance.
Precision-engineered capacitive multi-touch modules designed to meet local industrial standards.
Founded in 2016, we are a high-tech enterprise specializing in the R&D, production, sales, and service of premium liquid crystal modules. Our state-of-the-art facility is equipped with automated FOG lamination lines, high-temperature environmental aging rooms, and cleanroom packaging spaces.
To maintain our industry-leading edge, we reinvest over 30% of our net profit back into continuous R&D. This allows us to design high-complexity custom solutions addressing electrical noise, scratch resistance, extreme temperature ranges, and sunlight readability requirements.
Providing custom screen integration to solve local hardware and environmental challenges.
With the Hospital das Clínicas and major biotech centers concentrated in SP, medical electronics require top-tier precision. Our capacitive screens support sanitizing wipe agents, liquid spills, and gloved input operation, maintaining full calibration and structural integrity in critical medical displays.
São Paulo's banking infrastructure (Itaú, Bradesco, etc.) relies on high-security, high-durability input panels. We customize cover glasses with up to 6mm thick chemically-strengthened glass (IK08/IK10) and anti-glare coatings, ideal for retail kiosks and ATMs.
As EV infrastructure expands across SP, outdoor chargers demand high-brightness displays (up to 1500 nits) to fight bright tropical sun glare. Our UV-resistant and high-temperature-tolerant OCA bonding ensures non-yellowing and bubble-free lifespans.
Engineered for high performance, strict quality standards, and absolute configuration control.
From custom FPC configurations (lengths, positioning, pin definitions) to backlights (custom thickness, ultra-high nit arrays), and cover glass design (custom geometry, logos, special anti-glare/anti-fingerprint coatings).
Our factory operates under five quality inspections: Raw Glass incoming test, FOG microscopic lamination check, full functional product testing, IQC inbound, and OQC outbound inspection with direct serialization.
Every batch undergoes FOG high-temperature baking, thermal shock testing (-40°C to +85°C), vibration tests simulating transport on regional highways, and drop tests to guarantee device toughness.
We support custom prototyping and batch runs, with a safety stock buffer of 1,000 to 5,000 units on core components to protect supply lines against unexpected global transit bottlenecks.
A synergistic approach linking manufacturing craftsmanship with sustainable, win-win global cooperation.
Craftsmanship spirit forges products, and virtuous character builds careers. Let partners win together and promote social progress.
Full participation, meticulous research and development, continuous improvement, and sincere service to exceed industry standards.
Enhance quality, create brands, realize value, and achieve win-win cooperation with domestic and international integration partners.
Customer-centered, customer satisfaction; Adhere to the principle of quality first and remain continuously innovative.
Our capacitive touch panels utilize advanced IC families (FocalTech, Ilitek, Goodix) coupled with customized firmware tuning. This guarantees flawless touch detection even under high electromagnetic noise caused by nearby motors, heavy relays, and industrial power supplies.
By removing the air gap between the TFT LCD module and the cover glass, optical bonding prevents internal condensation in São Paulo’s humid climate. Optical bonding also improves contrast ratios and impact resistance, resulting in an exceptionally rugged finish.
For outdoor applications such as parking meters, EV chargers, and agriculture telematics, we apply dry-etched Anti-Glare (AG), Anti-Reflective (AR), and hydrophobic Anti-Fingerprint (AF) coatings to preserve maximum visibility and clean surfaces.
Standard consumer displays suffer from isotropic liquid crystal transitions when exposed to heat. Our industrial displays operate within a wide temperature range of -20°C up to +70°C, and storage tolerances up to +80°C.
Specific modules ideal for IoT nodes, handheld test equipment, and compact embedded devices.
Internationally audited facilities ensuring compliance with medical, industrial, and consumer markets.
Exporting industrial hardware components to Brazil demands detailed documentation to navigate MERCOSUR import controls. Xunrui provides complete commercial packaging invoices, exact HS Code classifications (under NCM rules), and certificates of conformity (RoHS, CE, FCC) to speed up clearance through customs (Receita Federal) at Guarulhos (GRU) Airport and the Port of Santos.
Our support desk regularly partners with São Paulo-based customs brokers (despachantes aduaneiros) to verify that all shipping documentation aligns with local guidelines, minimizing clearing delays.
Technical and logistical insights for engineering managers sourcing touch displays for Brazil.
We adjust the touch controller firmware registers (such as threshold limits, digital filtering, and baseline updates) to recognize water patterns. Our displays are tuned to ignore continuous wet layers while registering direct finger contact, meeting IP65 and IP67 wet-operation specifications.
We provide interfaces including HDMI, VGA, AV, and LVDS, plus standard controller interfaces such as I2C and USB. This guarantees plug-and-play compatibility with Linux, Windows, and Android hardware, including single-board computers like Raspberry Pi and industrial PCs.
Yes. We can laminate chemically-strengthened glass with thicknesses ranging from 2.0mm to over 6.0mm. We perform simulated drop-ball tests to meet IK08 and IK10 requirements, protecting terminal displays against vandalism and heavy public abuse.
Custom tooling design and prototype verification typically take 3 to 4 weeks. Once the sample is approved, bulk production is completed within 4 to 5 weeks. Shipping to São Paulo takes approximately 5 to 7 days via air courier, or 35 to 45 days via ocean freight.
