2.4 SPI TFT LCD Display, SPI TFT ILI9341, TFT Display ILI9341 240x320 - RFJ240L-AYW-DNN

2.4" MCU/ SPI TFT LCD Display ILI9341, 240x320

Model No. RFJ240L-AYW-DNN

RFJ240L-AYW-DNN is a 2.4-inch diagonal, 240x320 pixels, vertical/portrait TFT LCD display. RFJ240L-AYW-DNN is a TFT LCD display with IPS (In-Plane-Switching Liquid Crystal) panel; IPS technique allows viewers to view the screen from wider angles (80/80/80/80 degree).

This 2.4-inch TFT LCD display module has controller IC ILI9341V supporting MCU 8080 / SPI interface. The brightness is 500 cd/m2 with contrast ratio 500:1. Operating temperature covers from -20~+70℃, storage temperature range is from -30~+80℃. This design is a good fit for industrial application, testing equipment, etc.
