The WF121FSYAPLNB0 is a 12.1-inch high-brightness TFT capacitive display** designed for applications requiring precise visual clarity and responsive touch interaction. With a resolution of 1280 × 800 pixels (WXGA) and a 16:9 aspect ratio, this capacitive touchscreen display delivers sharp, detailed images even in bright lighting conditions, making it suitable for both indoor and outdoor use.
Featuring an LVDS interface, the module ensures stable and reliable data transmission. The integrated capacitive touch functionality is driven by the ILI2132 driver IC, supporting USB and I²C interfaces, and providing 10-point multi-touch capability. Its high sensitivity and accuracy allow smooth operation with multiple simultaneous touches, making this TFT capacitive display ideal for interactive systems such as medical devices, ATMs, industrial control panels, and self-service kiosks.
With a peak brightness of 800 nits and a contrast ratio of 1200:1, the module delivers vibrant and lifelike visuals. The IPS technology provides wide viewing angles of 85° in all directions, maintaining consistent color fidelity from multiple viewing positions. The capacitive touchscreen display ensures that user interaction is intuitive and precise.
Designed for reliability, the WF121FSYAPLNB0 operates within a temperature range of -20°C to +70°C, guaranteeing stable performance across varied environmental conditions.
