The WF70A2TIAGDNGB is a 7-inch TFT capacitive touchscreen display, designed to meet the high-performance needs of industrial and medical applications. Offering a resolution of 800 x 480 pixels, this display ensures clear and precise visuals for critical tasks. The TFT LCD technology delivers vibrant colors, while the capacitive touchscreen supports up to 5-point multi-touch, enabling smooth and intuitive interaction.
With a 24-bit RGB interface and the reliable ST5623D and ST5091D driver ICs, the WF70A2TIAGDNGB integrates easily into systems with minimal effort. Powered by the GT911 IC and communicating through an I2C interface, the capacitive touchscreen ensures responsive touch performance. This display operates within a temperature range of -20°C to +70°C and can withstand storage temperatures from -30°C to +80°C, making it ideal for demanding environments.
Compared to the WF70A2TIAGDNGA model, the WF70A2TIAGDNGB is equipped with the GT911 capacitive touch IC, while the WF70A2TIAGDNGA uses the ILI2130 IC, offering a different touch IC option to meet varying needs. Additionally, the cover glass (CG) of the WF70A2TIAGDNGB is larger than the TFT panel, making it easier for customers to secure the display in applications, improving installation flexibility and convenience.
Built for longevity and reliability, this 7-inch TFT capacitive display offers a contrast ratio of 800:1 and a brightness of 350 nits. The WF70A2TIAGDNGB features a long-lasting LED backlight with a lifespan of up to 50,000 hours, ensuring consistent performance over time. This extended lifespan minimizes maintenance and reduces the total cost of ownership, making it an excellent choice for industrial and medical applications where durability is crucial.
