The WF70D2TWAGLNN0 is a 7-inch IPS TFT LCD featuring a resolution of 800x480 pixels and an aspect ratio of 16:9. The WF70D2 series TFT LCD module, with IPS glass for wide viewing angles, offers superior visual performance with viewing angles of 85 degrees in all directions (left/right/up/down). This module is designed with an extended temperature range, making it ideal for applications that require robust performance in both high and low-temperature environments. Designed to operate effectively in temperatures ranging from -30°C to +80°C, it can also withstand similar storage conditions. It features a typical brightness of 450 cd/m² and a contrast ratio of 1500:1, ensuring sharp image quality and excellent readability across various lighting conditions.
The module integrates the RM53052 and RM57452 driver ICs. Additionally, the WF70D2 series has previously introduced models with the RGB interface, available in standard brightness, high brightness, CTP (Capacitive Touch Panel), and Non-Touch Panel variations.
The WF70D2TWAGLNN0 model, however, uses the LVDS interface, which offers enhanced signal integrity, lower power consumption, and improved noise resistance—ideal for high-performance applications. High-brightness and CTP options are also available for enhanced interactivity and visibility in bright environments.
This TFT module is suitable for a variety of applications, including industrial control systems, smart home appliances, medical equipment, and monitoring systems, especially those requiring reliable performance in extreme temperatures, thanks to its wide viewing angles and robust temperature tolerance.
