3.2" High Brightness Portrait TFT Display 240x320

Model No. RFJ320D-ALH-DNN

RFJ320D-ALH-DNN is a 3.2-inch color active matrix TFT-LCD display module. The dimension size of this module is 55.04x77.6 mm, size of active area is 48.6x64.8 mm (3.2”diagonal), and its resolution is 240x320 pixels. This TFT display module adopts controller IC ILI9341 supporting 80 MCU 8bit/9bit/16bit/18bit/SPI(3-Wire/4-Wire) Interface. It also features high brightness, providing brightness 1000 cd/m2 with contrast ratio (typical value) 500:1. RFJ320D-ALH-DNN TFT LCD module power supply voltage is 2.5~3.3V (typical 2.8V). The module works within temperature -20 to +70℃, storage temperature ranges from-30 to +80℃.
