The 21.5 inch TFT module has emerged as a cornerstone in the global display market, bridging the gap between compact handheld devices and large-scale digital signage. As industries transition towards more interactive and high-definition Human-Machine Interfaces (HMI), the 21.5-inch form factor—typically featuring a 16:9 aspect ratio and Full HD (1920x1080) resolution—has become the "golden size" for commercial and industrial applications.
In the current global landscape, the demand for 21.5 inch modules is driven by the surge in self-service kiosks, medical diagnostic equipment, and industrial control workstations. Unlike consumer-grade monitors, industrial 21.5 inch TFT modules must withstand rigorous environments, offering long-term availability, high brightness for outdoor readability, and wide viewing angles provided by IPS (In-Plane Switching) technology.
IPS DominanceThe shift from TN to IPS technology is undeniable. Modern 21.5 inch modules prioritize color accuracy and 178°/178° viewing angles, essential for medical imaging and collaborative industrial environments.
Smart IntegrationIntegration of PCAP (Projected Capacitive) touch screens with multi-touch capabilities is now a standard requirement, enabling intuitive gesture controls similar to smartphones.
High BrightnessFor semi-outdoor and high-ambient light environments, modules are now being engineered with 1000+ nits brightness and optical bonding to reduce reflection.
Founded in 2016, Shenzhen Xunrui Optoelectronics Technology Co., Ltd. is a high-tech enterprise specializing in the R&D, production, sales, and service of liquid crystal modules. We stand at the forefront of the display industry, investing over 30% of our net profit annually into R&D to ensure our customers receive the most advanced technology.
Our facility spans 5,000 square meters and is equipped with 30 sets of advanced production machinery, allowing us to maintain a monthly capacity of 2 million units. We are not just a manufacturer; we are a partner in innovation.
We offer full customization for FPC (lead-out position, length), Touchscreens (PCAP/Resistive), and Backlight brightness (up to 2000 nits).
Our "Five Quality Inspections" include Glass, FOG, Finished Product, IQC, and OQC, ensuring a 99.9% reliability rate for industrial use.
We provide one-stop services including driver boards (HDMI/VGA/LVDS) and supporting touch interfaces (IIC/USB).
