Explore our certified display lineup engineered with IPS wide viewing angles, enhanced LED backlighting, integrated capacitive and resistive digitizers, and robust industrial controller boards.
Why this legacy 4:3 display format remains an irreplaceable cornerstone of industrial automation, critical infrastructure, laboratory diagnostics, and specialized embedded computing globally.
While consumer displays rushed towards ultra-wide 16:9, 18:9, and circular geometries, industrial programmable logic controllers (PLCs), human-machine interfaces (HMIs), and specialized oscilloscopes were fundamentally built around the 4:3 VGA (640×480) and QVGA (320×240) aspect ratio. The 5.7-inch panel is an industry benchmark: it maximizes vertical pixel density for telemetry readouts, ladder logic, waveform graphs, and multi-variable parameter lists without excessive horizontal bezel width.
Hundreds of thousands of high-value capital assets worldwide—ranging from Siemens CNC machine controllers, Fanuc robots, Kyocera machine interfaces, to medical anesthesia carts—were built between 2000 and 2018 utilizing 5.7" CCFL-backlit panels. When CCFL tubes darken or inverters burn out, complete machine decommissioning is financially unfeasible. As a leading China 5.7 LCD panel manufacturer, Xunrui delivers pin-compatible LED-backlit replacement modules that reduce power draw by 40% and boost lifetime.
Global procurement teams favor sourcing 5.7-inch modules from China's Greater Bay Area due to unrivaled supply chain cohesion. At Xunrui's Shenzhen facility, precision glass cutting, high-speed COG/FOG micro-bonding, optical cleanroom assembly, custom FPC fabrication, and touch digitizer integration take place under one roof. This geographic cluster eliminates component delays, ensures aggressive cost control, and allows flexible trial production runs (5 to 500 pcs) before committed mass scaling.

Examining real-world deployments where the mechanical dimensions, aspect ratio, and electrical characteristics of our 5.7" display modules solve mission-critical challenges.
Handheld teach pendants and wall-mounted PLC enclosures require a compact form factor that can withstand repetitive drops, heavy hydraulic fluids, and severe electromagnetic interference (EMI). Our 5.7-inch modules feature 4-wire or 5-wire resistive touch panels engineered for gloved operation, alongside reinforced FPC grounds that pass strict EN 61000-4-2 (ESD) and EN 61000-4-4 (EFT) compliance certifications.
Medical intensive care equipment demands 100% color fidelity, wide viewing angles so nurses can observe telemetry from any vantage point, and seamless surface cleaning with caustic hospital disinfectants (bleach, isopropyl alcohol). Xunrui pairs 5.7" IPS glass with chemically strengthened cover lenses (Corning Gorilla Glass equivalent) utilizing full optical resin bonding (OCR) to eliminate condensation and microbial harboring.
Vessels, tractors, and forestry combines operate under unshielded direct sunlight and high-humidity salt-fog atmospheres. Standard 300-nit displays wash out into total illegibility. We engineer high-brightness 5.7" displays generating 1,000 to 1,500 nits via high-efficiency Nichia LED arrays, married with circular polarizers and Anti-Reflective (AR) optical bonding that slashes internal refraction below 0.5%.
Underground mining loaders and aerospace avionics require absolute structural survivability under continuous mechanical vibration, shock profiles exceeding 50G, and sub-zero Arctic cold starts. Our ruggedized 5.7-inch displays incorporate integrated ITO transparent heating foils, wide-temperature liquid crystal fluid, and aerospace-rated silicone potting around all wire bonds and driver IC connections.
