4D Systems gen4 FT81x Series Embedded SPI Displays

4D Systems gen4 FT81x Series Embedded SPI Displays feature a resistive touch panel or capacitive touch panel display, with an integrated FTDI FT81x video engine. The FT81x video engine targets high-quality graphics displays with widget support, designed to offload the Host Processor and provide a variety of graphic features.

The 4D Systems gen4 FT81x Series Embedded SPI Displays feature a 4.3", 5.0", or 7.0" color TFT LCD display. The display provides 4 in 1 functionality, a TFT LCD Display (4.3"/5.0"/7.0"), audio with an amplifier enable, resistive/capacitive touch screen, and an integrated video engine. This combination built directly into the screen allows for simple integration into several applications. The FT812 is for resistive touch models, and the FT813 is for capacitive touch models.
