Description

The WF121FSYAPLNB0 is a 12.1-inch high-brightness transmissive TFT LCD display module featuring a capacitive touch screen, designed to deliver excellent clarity and visibility across various environments. With a resolution of 1280 x 800 pixels and a 16:9 aspect ratio, it produces sharp, detailed images that remain clear even in bright lighting conditions. The module supports the LVDS interface, ensuring stable and reliable connectivity, which further enhances its versatility.

The capacitive touch functionality is driven by the ILI2132 driver IC, supporting both USB and I2C interfaces, and provides highly responsive 10-point multi-touch capabilities. This makes it ideal for interactive applications that require precise and intuitive touch input, enabling seamless user interaction with the display. The touch screen’s high sensitivity ensures smooth operation, even with multiple simultaneous touches, making it suitable for applications such as medical equipment, ATMs, industrial control, and kiosks, where reliability and accuracy are critical.

This module offers a brightness of 800 nits, ensuring clear visibility even in outdoor or brightly lit environments. The 1200:1 contrast ratio enhances image detail and vibrancy, delivering rich, lifelike visuals. Additionally, the display offers IPS-wide viewing angles of 85° in all directions, ensuring consistent and accurate color reproduction from multiple angles.

Designed for durability and high performance, the WF121FSYAPLNB0 operates within a wide temperature range of -20°C to +70°C, ensuring reliable performance in various environmental conditions.
