Description

WFN2150A2T0AFLHN000 is a 21.5-inch HDMI TFT LCD display module featuring a 1920 x 1080 (Full HD) resolution, an IPS panel with an 89/89/89/89 wide viewing angle, and a built-in control board. The module supports HDMI video input (excluding audio), with the LT6911C controller IC converting the HDMI video signal to LVDS for the TFT panel.

The integrated PCBA has undergone third-party EMI testing and passed Class B level requirements. The board-level EMI performance has therefore been evaluated to support electromagnetic compatibility considerations during system integration.

The module measures 497.6 x 292.2 x 30.0 mm, with a 476.06 x 267.79 mm active area and a typical brightness of 500 cd/m². It features an anti-glare (3H) surface, a USB Type-C 12 V power input, and operates over a temperature range of -10°C to +60°C. The module is suitable for industrial control equipment, medical devices, information displays, kiosks, and other embedded HMI applications requiring a large-format TFT display.
