4.3 inch 480x272 IPS TFT LCD Display with PCAP / Controller Board / BT815 IC

Model No. RFE430W-EYW-DSG

RFE430W-EYW-DSG is a TFT LCD display with IPS (In-Plane-Switching Liquid Crystal) panel, controller board and PCAP touch; IPS technique allows viewers to view the screen from wider angles (80/80/80/80 degree). The brightness is 400 cd/m2 with contrast ratio 800:1(typical value). This 4.3 inch TFT display module has a built-in controller IC BT815 supporting SPI/QSPI interface. The module adopts IC ILI2130 for PCAP touch supporting I2C interface and 5-point touch. The module works within the temperature -20 to+70℃, storage temperature covers from-30 to+80℃.
