7 Capacitive Touch Screen Module with Controller Board - RFF70BQ-1IW-DBG

7" Capacitive Touch Screen Module with Controller Board

Model No. RFF70BQ-1IW-DBG

RFF70BQ-1IW-DBG is one of the models in our Q series---7-inch TFT-LCD display module with controller board and PCAP touch. The resolution of this module is 800x480 pixels. PCAP touch panel adopts IC FT5426 supporting I2C interface and 5-point touch. The Q series mainly uses IC SSD1963. TFT modules of this series are all characterized by 36-pin MCU 8080 8/16-bit pin define, and the 8/16-bit 6800 pin define interface can be selected through Jump. Compared to the P series, functions of Q series are simple and pricing is relatively lower.

The brightness is 380 cd /m2 with contrast ratio 500:1. LCM voltage ranges from 3V-3.3V, typical value is 3.1V. Operating temperature covers from -20~+70℃, storage temperature range is from -30~+80℃.
