Resistive Touch Screen Color TFT 4.3 with Controller Board - RFE43DP-EIW-DBS

Resistive Touch Screen Color TFT 4.3" with Controller Board


RFE43DP-EIW-DBS is one of the models in our P series---4.3-inch TFT-LCD display module with controller board and Resistive touch. The resolution of this module is 480 x 272pixels, and it has 4 screw holes & metal frame allowing for quick mounting. The P series mainly uses RA8875 Controller IC. The TFT modules of this series are all characterized by the 36pin MCU 8080 8/16-bits Pin define, and 8/16-bits 6800 Pin define Interface can be selected through Jump. In addition, you can request external expansion of Chinese fonts (Optional) and flash memory. Through the built-in PWM Command of RA8875 IC, it can control its backlight and DMA (Direct Memory Access) to accelerate graphics.

The brightness is 350 cd/m2 with contrast ratio 500:1. LCM voltage ranges from 3V-3.6V, typical value is 3.3V. Operating temperature covers from -20~+70℃, storage temperature range is from -30~+80℃.
