2.8" IPS High Brightness TFT LCD Display 240x320

Model No. RFJ280J-AYH-DNN

RFJ280G-ALW-DNN is a 2.8-inch, IPS, vertical/portrait, active matrix TFT-LCD module. Its resolution is 240Xx320 pixels (width 240 pixels x height 320 pixels) with aspect ratio 3:4. The module features wide viewing angle thanks to the IPS panel which is one of the most popular techniques on the market now. This 2.8-inch TFT module adopts driver IC ILI9341V supporting MCU/SPI interface. The brightness is 1000 cd/m2 with contrast ratio 800:1. Operating temperature covers from -20~+70℃, storage temperature range is from -30~+80℃. This design is a good fit for industrial application, medical equipment, home appliances, etc.
