7-inch Capacitive Touch Screen Display - RFF70AB2-AIH-DNG - Raystar

7-inch Capacitive Touch Screen Display 800x480 TFT with PCAP (HX8264-E+HX8664-B IC)

Model No. RFF70AB2-AIH-DNG

The RFF70AB2-AIH-DNG is a 7-inch capacitive touch screen display module designed for embedded and industrial display applications. This 7-inch capacitive touch screen display integrates the HX8264-E and HX8664-B driver ICs supporting a 24-bit RGB interface and includes a built-in DC-to-DC converter. Capacitive touch functionality of the7-inch capacitive touch screen display is handled by an ILI2130 PCAP driver IC via an I2C interface, enabling 5-point touch detection.

This 7-inch capacitive touch screen display provides a typical contrast ratio of 800:1, a brightness of 700 nits, and a 16:9 aspect ratio. In addition, the RFF70AB2 series is fully compatible with the RFF700Y series, allowing users of existing 7-inch capacitive touch screen display solutions to migrate without redesign.
