WF121ETWAMLNN0 is a 12.1-inch Wide Temperature TFT LCD with excellent IPS angle visibility. This display features a resolution of 1024x768 pixels, a typical brightness of 600 nits, and a contrast ratio of 1000:1. With an aspect ratio of 4:3 and an anti-glare surface panel, this 12.1-inch 1024x768 TFT LCD display utilizes an IPS (In-Plane Switching) Panel, providing wider viewing angles of approximately Left:89 / Right:89 / Up:89 / Down:89 degrees (typical).
The module supports LVDS interfaces, which are increasingly popular for TFT displays requiring high-speed data transmission. LVDS offers advantages such as compatibility with lower voltage power supply and noise, improved noise suppression, and reliable signal transmission. The WF121ETWAMLNN0 module operates at temperatures ranging from -30℃ to +85℃, with storage temperatures ranging from -40℃ to +90℃.
The 12.1-inch 1024x768 TFT display is highly suitable for monitoring equipment, measuring instruments, IoT devices, and medical equipment.
For medical equipment applications, 12.1-inch TFT displays are crucial for healthcare professionals in Intensive Care Units (ICUs) and Emergency Departments (EDs), providing high resolution and multifunctional visual experiences. These displays monitor vital signs and serve as platforms for displaying critical patient data and medical imaging.
In ICUs, they facilitate quick identification of changes in patients' conditions by displaying laboratory results and medication schedules, while in EDs, they support informed decision-making for rapid assessment and treatment by presenting patient information. These displays foster effective communication and collaboration among medical staff, ensuring reliable and high-quality patient care.
