Product Overview
The No Polarizer Film 21.5 Inch Open Frame Screen is an industrial-grade display solution engineered for applications requiring high light transmittance, sunlight readability, and seamless integration into professional equipment. Unlike traditional LCD modules, this design removes the polarizing film, allowing natural or rear-projected light to pass through while maintaining clarity under strong ambient light. With its open-frame structure, wide viewing angles, and durable materials, it is ideal for industrial automation, medical devices, commercial terminals, and environments where reliability and optical performance are critical.
Key Features
* Non-Polarizer Optical Architecture for higher light transmittance and improved visibility under sunlight or polarized eyewear.
* 21.5-inch FHD TFT LCD with 1920×1080 resolution and 178° viewing angle for accurate color and stable imaging.
* Industrial Temperature Tolerance from -10°C to +50°C for long-term 24/7 operation.
* Flexible Mounting Options including panel mount, VESA, wall mount, and embedded configurations.
* Optional Touch Solutions such as 4-wire resistive touch with USB or RS232.
* Multiple Interfaces (VGA standard, optional HDMI/DVI/USB) for easy system integration.
* Open-frame design optimized for kiosks, terminals, and self-service equipment.
Detailed Product Description
The No Polarizer Film 21.5 Inch Open Frame Screen uses a modified TFT LCD module without a polarizer layer, significantly improving light transmission and reducing reflection loss. This optical configuration ensures stable contrast even under direct sunlight, making it suitable for outdoor terminals, industrial workstations, and high-brightness environments where traditional LCDs perform poorly.
The 21.5-inch display features a full-HD 1920×1080 panel with 250 nits brightness and a 500:1 contrast ratio. Its IPS technology delivers a 178° viewing angle, ensuring consistent color reproduction from all directions-a requirement for operator panels, medical interfaces, and commercial displays.
Engineered for industrial reliability, the unit supports a working temperature range of -10°C to +50°C and adopts a fanless structure to reduce dust intake, operational noise, and maintenance frequency. RoHS-compliant manufacturing further supports strict European environmental standards.
The open-frame design allows seamless integration into enclosure-based systems, kiosks, vending machines, ticketing systems, and OEM equipment. Installation flexibility is supported by panel mounting, VESA mounting, and custom embedded mounting brackets.
Touch functionality is available with a durable 4-wire resistive touchscreen, offering compatibility with gloves, styluses, and industrial environments. Connectivity includes standard VGA input and optional upgrades to HDMI, USB, or DVI depending on system requirements.
