Featured Industrial & Custom TFT LCD Modules
Precision optical bonding, high-nit backlighting, and flexible interface driver integration engineered across standard, bar, and custom form factors.
Engineering the Modern 5.7 Inch Industrial Display Interface
Why the 5.7-inch diagonal remains an irreplaceable sweet spot in heavy industrial automation, diagnostic telemetry, and human-machine interaction systems worldwide.
Legacy Form-Factor Preservation
For more than two decades, the 5.7" display with a 4:3 native aspect ratio (traditionally 320×240 QVGA and 640×480 VGA) anchored tens of thousands of factory-floor controllers, CNC programming pendants, and marine navigators. Our custom manufacturing lines engineer modern IPS open cells while reproducing historical bezel profiles, screw mounts, and FPC pin allocations for painless 1:1 drop-in replacement without mechanical retooling.
Optoelectronic Enhancement Stack
Original CCFL backlight tubes degraded drastically after 20,000 operational hours. Our 5.7 inch replacement and new-build modules implement custom edge-lit and matrix LED backlight configurations driving 800 to 1,500 nits of high luminance with 50,000+ hour MTBF. Combined with anti-reflective (AR), anti-glare (AG), and transflective optical stack additions, displays retain peak contrast under direct zenith sunlight.
Harsh Environment Hardening
Industrial machinery deployed across mining, cold-chain logistics, and offshore drilling undergoes intense thermal cycling. Our custom 5.7" platforms are fabricated using wide-temperature liquid crystal fluid and specialized polarizers, guaranteeing reliable operation between -30°C and +85°C without ghosting, sluggish refresh decay, or clearing point artifacts.
Localized Application Scenarios for 5.7 Inch Modules
From cleanrooms to rugged tractor cabs, the 5.7" display profile balances single-hand ergonomic viewing with dense diagnostic data display requirements.
Clinical Diagnostic Devices
Infusion pumps, blood gas analyzers, and portable ultrasound scanners utilize custom 5.7" IPS modules with Projected Capacitive (PCAP) touch sensors calibrated for sterile latex glove operation and chemical wipe-down resistance.
Industrial PLC & HMI Terminals
Factory automation panels, automated guided vehicle (AGV) interfaces, and CNC machinery controllers rely on 5.7" 4-wire resistive touch modules to ignore extreme EMI noise and function reliably in dusty, oily grease environments.
Marine & Avionics Telemetry
Echo sounders, rudder indicators, engine status consoles, and light aircraft cockpit avionics need extreme sunlight contrast. Our 1200+ nit optical-bonded 5.7" displays prevent internal condensation and eliminate reflections completely.
Precision Test & Measurement
Handheld digital storage oscilloscopes, optical spectrum analyzers, and underground pipeline detectors integrate low-power 5.7-inch modules featuring custom LVDS or SPI backhaul for clean waveform rendering and minimal battery draw.

Full Optical Bonding (OCA/LOCA)
Traditional displays trap an air gap between the LCD polarizer and the cover glass, producing twin Fresnel reflective surfaces that wash out graphics in high ambient light. Our cleanroom optical bonding replaces the air cavity with refractive-index-matched optical silicone or OCA resin, cutting surface reflections by up to 88% while quadrupling mechanical impact resistance.
Component Availability Guarantee
Nothing harms an industrial OEM project more than sudden open-cell obsolescence. Xunrui secures long-term master wafers directly from leading glass foundries and freezes FPC layouts, driver IC selections, and LED die configurations to guarantee form, fit, and functional continuity across guaranteed 7 to 10+ year manufacturing lifespans.
Flexible Pinout Adaptation Boards
Retrofitting discontinued Sharp, Kyocera, or Tianma 5.7" panels? Our Shenzhen engineering department designs tailored translation boards and flexible flat cables that convert obsolete 33-pin or 40-pin signals directly to modern high-reliability LVDS or RGB receivers without altering your main controller PCB firmware.
Shenzhen Cleanroom Manufacturing: Agility, Scale & Resilience
Located in Bao'an District, Shenzhen, our facility capitalizes on the world's dense optoelectronic cluster to compress prototype and production delivery times.
5-Tier Cleanroom Quality Control
Every custom 5.7" module transitions through strict control gates: Incoming Material Quality Control (IQC) for raw glass and driver ICs; precision COG/FOG bonding inspection with pre-lamination thermal stress testing; continuous 48-hour powered burn-in aging; completed module functional validation; and outgoing cosmetic optical analysis (OQC) under Class 1,000 cleanrooms.
Low Risk Prototyping & Pilot Batches
Tier-1 display conglomerates frequently demand MOQs of 20,000 to 50,000 units before accepting custom tooling inquiries. Xunrui bridges the gap between R&D innovation and mass production by providing initial prototype iterations followed by a 5 to 500 pcs small-batch trial run to validate thermal, mechanical, and optical tolerances before committing to 1,000+ unit mass tooling runs.
Complete Accessory Ecosystem
We eliminate supply friction by offering end-to-end integration: custom front cover lenses (custom silk-screened borders, company branding, antimicrobial treatments), anti-shatter chemically strengthened glass, resistive or I2C/USB PCAP touch layers, and companion A/D driver boards handling direct HDMI, VGA, composite video, or custom serial bus inputs.

Our engineers incorporate internal ground copper shield planes, ferrite bead filtering, and differential pair impedance matching within the FPC to ensure effortless CE and FCC system-level certification.
Frequently Asked Technical & Procurement Questions
Detailed technical insights directly from our engineering leads on custom 5.7" display integration, retrofits, and mass production constraints.
Yes. We specialize in drop-in replacement solutions. Our engineering department matches original mechanical outer dimensions, active viewing areas, mounting screw hole brackets, and backplate thickness. Electrically, we design daughterboards or custom FPC pin-outs that translate legacy 8-bit/16-bit parallel signals, or we supply small HDMI/VGA/LVDS adapter kits so you can upgrade from monochrome/STN to full-color IPS without redesigning your housing.
Initial engineering drawings for the display structure, FPC trace layout, and pinout are delivered within 3 to 5 business days for customer review. Following formal approval, custom FPC tooling, glass cutting, and sample assembly typically take 15 to 20 business days. Mass production tooling and delivery of the small trial batch (5–500 pcs) follow within 3 to 4 weeks after sample verification.
Choose PCAP when your device requires smartphone-like smooth multi-touch gestures, a flush-bezel surface aesthetic, chemically toughened IK08/IK10 cover glass, or resistance against harsh chemical disinfectants. Choose 4-wire resistive touch when your equipment will be used on oil-splattered shop floors, in high-vibration heavy equipment, operated with thick leather work gloves, or exposed to intense electrical magnetic interference where capacitive false triggers cannot be tolerated.
We avoid simply overdriving low-efficiency LEDs, which causes premature luminance degradation and dangerous device heating. Instead, our custom optical stacks employ high-efficiency Nichia LED dies, high-gain brightness enhancement films (BEF and Dual-BEF), and full refractive optical bonding with OCA to minimize internal light reflection. This achieves 1,000 to 1,500 nits of sunlight clarity while holding power consumption within manageable thermal envelopes for enclosed industrial housings.
We do not force immediate high-volume purchase commitments. Following initial sample approval, we offer a dedicated, one-time trial batch run of 5 to 500 units to allow complete validation on your manufacturing pilot line. When you transition to full commercial volume production, our standard custom production MOQ is 1,000 units, backed by structured safety stock agreements to support your rolling manufacturing forecasts.
We subject our display assemblies to 5 distinct quality gates: IQC raw material inspection, glass cell microscopic inspection, FOG bonding validation with dynamic temperature cycling, 100% active powered burn-in aging for 48 to 72 hours under elevated temperatures, and final OQC optical inspection for luminance uniformity, color coordinates, and mechanical zero-defect tolerances.
