21.5-inch Industrial TFT LCD Display with PCAP Touch – Full HD, High Brightness, Wide Temperature for HMI & Kiosk Applications
Saef Technology Limited introduces a professional-grade 21.5-inch industrial TFT LCD display module, combining a high-brightness 1000-nit panel, projected capacitive touch, and rugged design for demanding environments. Engineered for industrial HMIs, medical imaging, public information displays, gaming systems, and interactive kiosks, this display delivers exceptional clarity, responsive touch, and reliable operation under extended temperature ranges.
✅ Full HD Resolution with High Brightness
1920 × 1080 pixel resolution and 1000 cd/m² brightness ensure sharp, vivid visuals even in high-ambient light or outdoor conditions.
✅ Integrated Projected Capacitive Touch (PCAP)
Multi-touch capable with excellent transparency and durability—ideal for interactive applications requiring gesture input.
✅ Wide Viewing Angles & High Contrast
89° viewing angles (all directions) and 1000:1 contrast ratio provide consistent image quality from various viewing positions.
✅ Wide Operating Temperature Range
Rated for -10°C to +60°C, suitable for use in uncontrolled environments such as factories, warehouses, outdoor kiosks, and transportation systems.
✅ Industrial-Grade Construction with Oxide TFT
Oxide TFT technology offers higher electron mobility, enabling faster response and lower power consumption, while the anti-glare 3H surface resists scratches and reflections.
✅ Dual-Channel LVDS Interface
Simple, robust interface ensures reliable data transmission over longer cable lengths, compatible with common industrial SBCs and controllers.
✅ Extended Reliability & Lifespan
LED backlight rated for 50,000 hours (to 50% brightness) and comprehensive reliability testing including thermal shock, humidity, and temperature cycling.
✅ Customization Options
We offer semi-custom design support—adjust touch controller firmware, modify bezels or mounting, integrate protective glass, or tailor I/O configurations to your system requirements.
Saef’s 21.5-inch TFT module addresses common design challenges in industrial displays:
Integrated touch controller reduces external components and simplifies system design
EMI-optimized PCB layout minimizes noise interference in electrically noisy environments
Detailed power sequencing guidelines ensure safe startup/shutdown and extended panel life
Mechanical drawings with mounting references provided for seamless integration into enclosures and panels
Whether you’re developing a factory HMI, medical monitor, digital signage platform, or interactive retail display—this module delivers professional performance with minimal integration overhead.
Technical Authority: Our engineering team specializes in industrial display solutions, offering schematic reviews, signal integrity analysis, and thermal management guidance.
Fast Prototyping: Engineering samples available in 7–10 business days with complete documentation.
Global Compliance: CE-ready, RoHS, REACH, and ISO 9001/14001 certified for EU and North American markets.
Quality Assurance: Each module undergoes strict AQL inspection per MIL-STD-105E, with full reliability validation.
