DESCRIPTION
WF70A9SWAGLNN0 is a 7” High Brightness with Wide Temperature IPS TFT-LCD display, made of resolution 800x480 pixels. This module is built in with HX8249-A and HX8678-C driver ICs, it supports LVDS interface. The LVDS（Low-Voltage-Differential-Signaling）becomes more popular for TFT LCD display. WF70A9SWAGLNN0 module was designed to use LVDS interface which is a popular choice for TFT LCDs and peripherals in need of high bandwidth, like high-definition graphics and fast frame rates. It is a great solution because of its high speed of data transmission while using low voltage and improved noise performance.
WF70A9SWAGLNN0 is adopted IPS panel which is having the advantage of wider view angle of Left:80 / Right:80 / Up:80 / Down:80 degree (typical value), contrast ratio 1000:1 (typical value), high brightness 1000 nits (typical value), anti-glare surface panel, aspect ratio 15:9. The supply voltage (VCC) of WF70A9SWAGLNN0 is from 2.7V to 3.6V, typical value 3.3V. It can be operating at wide temperatures from -30℃ to +80℃ and storage temperatures from -40℃ to +85℃.
