LCD TFT Display 4.3 with Controller Board - RFE43DQ-EIW-DBN

LCD TFT Display 4.3" with Controller Board

Model No. RFE43DQ-EIW-DBN

RFE43DQ-EIW-DBN is one of the models in our Q series--- 4.3-inch TFT-LCD display module with controller board. The resolution of this module is 480 x 272pixels, and it has 4 screw holes & metal frame allowing for quick mounting. 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 500 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℃.
