WF70A9TWAGDNT0 is a 7-inch, 800×480 wide-temperature IPS TFT-LCD display with a resistive touch panel (RTP). It integrates HX8249-A and HX8678-C driver ICs and supports a 24-bit RGB interface.
The IPS panel offers wide viewing angles: 80° (left), 80° (right), 80° (up), and 80° (down) (typical values). It features a 1000:1 contrast ratio, 350 cd/m² typical brightness, and an anti-glare surface. The active area has a 15:9 aspect ratio. For applications requiring higher brightness, consider the WF70A9SWAGDNT0 model.
The display operates with a supply voltage (VCC) ranging from 2.7V to 3.6V, with a typical value of 3.3V. It supports a wide operating temperature range from -30℃ to +80℃ and can be stored in temperatures from -30℃ to +80℃.
