  2. Brightness and Contrast Ratio: For indoor use, 300-500 nits is sufficient. For outdoor or high-ambient-light environments, demand 800 nits or higher. A contrast ratio above 800:1 ensures deep blacks and vivid colors.
  3. Viewing Angle: IPS (In-Plane Switching) technology is now standard for premium TFT LCD 4.3 modules. It provides 80/80/80/80 degree viewing angles, eliminating color shift. Avoid TN panels for professional products.
  4. Interface Compatibility: Common interfaces include RGB, LVDS, MIPI DSI, and MCU. Ensure the display driver IC supports your host controller. Many OEMs prefer modules with pre-integrated FPC connectors and custom pinouts.
  5. Touch Panel Integration: Decide between resistive (cost-effective, works with gloves) and capacitive (multi-touch, better user experience). Verify the touch controller IC and driver support for your OS.
  6. Operating Temperature Range: Industrial applications typically require -20°C to +70°C. Automotive or outdoor products may need -30°C to +85°C. Confirm the storage temperature range as well.
  7. Certifications and Compliance: A reputable TFT LCD 4.3 factory should provide RoHS, REACH, CE, and FCC certifications. For medical or automotive use, ISO 13485 or IATF 16949 may be mandatory.

When evaluating a potential global supplier, always request a datasheet and a pre-production sample. Test the sample under your actual operating conditions, including temperature, humidity, and vibration. This step alone can prevent costly redesigns later.
