RFN21500A210AWLHN00 - 21.5-inch HDMI IPS TFT LCD Module

21.5-inch 1920x1080 HDMI IPS TFT LCD Module with Control Board (LT6911C IC)

Model No. RFN21500A210AWLHN00

The RFN21500A210AWLHN00 is a 21.5-inch 1920 × 1080 HDMI IPS TFT LCD module with a control board, featuring a Normally Black, Transmissive display mode and 89/89/89/89 viewing angles provided by an IPS panel. The module incorporates the LT6911C controller IC, supports a DVI interface, features an Anti-Glare (3H) surface treatment, and is supplied without a touch panel.

The module integrates a new PCB that utilizes the LT6911C to convert the input signal into an LVDS output through an HDMI connector (video only, excluding audio). A USB Type-C connector is provided for power input. The module also complies with EMI Class B requirements, offering stricter electromagnetic interference performance than Class A and enabling deployment in industrial, commercial, and residential environments under a single certification.

If you require technical support or would like a quotation for the RFN21500A210AWLHN00, please feel free to contact our sales team.
