Product Description
The TFT-H035A3HVIST4R50 is a 3.5-inch wide temperature IPS TFT-LCD monitor with a projected resistive touch screen with a resolution of 320X480 pixels. The module has built-in ST7796S driver IC, which supports MIPI fully compatible interface. TFT-H035A3HVIST4R50 adopts IPS panel, which has the advantage of wider viewing angle, left: 80/right: 80/up: 80/down: 80 degrees (typical value), contrast ratio 800:1 (typical value), brightness 400 nits (typical value) value), glare panel, 1:1.5 aspect ratio. Support I2C interface and single touch function. The H035A3H model has a projected resistive touch panel (CTP), and the TFT-H035A3HVIST4R50's supply voltage (VCC) is 2.5V to 3.0V, typically 2.8V. It can operate at temperatures from -20°C to +70°C and storage temperatures from -30°C to +80°C.
