Description

The WF70B4SIAGDNT0 is a 7-inch TFT LCD module featuring a resolution of 800×480 dots and a luminance of 600 nits, providing high visibility in various environments. This module is equipped with a Resistive Touch Screen (RTP) and uses the HX8264 + HX8664 driver ICs with an RGB interface.

The display offers a 12 o’clock viewing direction with grayscale inversion at 6 o’clock, and its 16:9 aspect ratio makes it suitable for wide-format applications. It operates with a logic supply voltage (VCC) ranging from 3.0V to 3.6V (typical 3.3V). The operating temperature range is -20°C to +70°C, and the storage temperature range is -30°C to +80°C, ensuring reliability in demanding environments.

For applications that do not require high brightness, an alternative model, WF70B4TIAGDNT0, with a standard luminance of 250 nits is also available.
