Tianfu 4.3' Normally White Square TFT LCD Display Module Details

Q1: Which main control chips does this display support?

A: This module uses a standard SPI interface and is compatible with most embedded platforms, including STM32, ESP32, Raspberry Pi Pico, Arduino (level shifting required), and various industrial PLCs.

Q2: What is the difference between a resistive touch screen and a capacitive touch screen? Which is more suitable for my application?

A: A resistive screen operates by pressure sensing and supports touch with gloves, styluses, or any object, making it more suitable for industrial environments, medical devices, or scenarios requiring precise tapping. A capacitive screen only supports finger touch but offers multi-touch capability. If your application requires gloved operation or may involve oil/water contamination, a resistive screen is the more reliable choice.

Q3: How to understand the viewing angle parameters? My device will be viewed at an angle—will it work?

A: This module has a horizontal viewing angle of 60°–70° and a vertical viewing angle of 45°–60°, suitable for front‑on or small‑angle viewing. If your device requires viewing from large angles (e.g., from the side), we recommend considering an IPS wide‑viewing‑angle model.

Q4: Does the operating temperature range of -10°C~60°C include the effect of backlight heating?

A: Yes, this temperature range applies to the module’s overall operating temperature and already accounts for backlight heating. Testing in the actual target environment is recommended when operating at extreme temperatures. Q5: Do I need to purchase an additional driver board or controller?

A: This is an integrated display‑and‑touch module that already includes the display driver and touch controller. You only need to connect it to your main controller via SPI and RGB interfaces.
