WF70B8SWAGDNB0 is a 7-inch High Brightness 800 x 480 IPS TFT-LCD module with PCAP touchscreen. This TFT-LCD module adopted IPS technology which has the advantage of a wide viewing angle of Left:80 / Right:80 / Up:80 / Down:80 degrees. WF70B8SWAGDNB0 module is built-in with HX8249-A and HX8678-C driver ICs; it supports 18-bit RGB interface, contrast ratio of 1000:1 (typical value), brightness of 800 nits (typical value), glare surface panel, aspect ratio 15:9. This model featured a projected capacitive touch panel (PCAP), which built-in with ILI2511 IC, supports USB interface (I2C available). It has wider operation temperatures from -30℃ to +80℃; its storage temperatures range from -40℃ to +85℃.
