7 inch Wide Temperature LCD, Wide Temperature TFT LCD - RFF700A9-AWW-DNN

7" Wide Temperature IPS TFT LCD

Model No. RFF700A9-AWW-DNN

RFF700A9-AWW-DNN is a 7-inch wide temperature TFT LCD display with aspect ratio: 15:9, resolution 800x480 dots. This TFT module uses IPS screen which allows users to see the display clearly at wider angles. The brightness is 500 cd/m2 with contrast ratio 1,000:1. With the help of a anti-glare display surface, the screen doesn’t reflect light and preserves better image quality.

This wide temperature LCD module uses HX8249-A + HX8678-C IC which supports 24 bit R.G.B interface. VCC voltage of RFF700A9-AWW-DNN ranges from 2.7V to 3.6V; typical value is 3.3V. The module works within wide temperature range from -30℃ to +80℃; storage temperature is -40℃ to +85℃. In this RFF700A9 series, there are resistive touch screen (RTP) and capacitive touch screen (PCAP) options available. We also provide a high brightness version.
