WF70A9SWAGDNB0 is a 7-inch high brightness IPS TFT LCD with an 800×480 resolution and a projected capacitive touch screen (PCAP). This model is equipped with HX8249-A and HX8678-C driver ICs and supports a 24-bit RGB interface.
The display provides a typical brightness of 800 cd/m² and a contrast ratio of 1000:1. The IPS panel offers wide viewing angles (80/80/80/80, typical) and features a glare surface with a 15:9 aspect ratio. The module dimension is 165.8 × 106.61 × 8.9 mm, with an active area of 152.40 × 91.44 mm.
The capacitive touch panel is driven by an ILI2511 controller IC, supporting USB interface (I2C available) and 10-point touch for multi-touch input. The logic supply voltage (VCC) ranges from 2.7V to 3.6V, with a typical value of 3.3V. The module supports ultra wide temperature operation from -30°C to +80°C and can be stored from -40°C to +85°C.
