Here are some important considerations for the daily use of touch products

● Cleaning: Regularly clean the touch screen to remove fingerprints, smudges, and dust. Use a soft, lint-free cleaning cloth or specialized touch screen cleaner. Avoid using abrasive or harsh substances.

● Touching method: Use your fingers or compatible touch pens for touch operations. Avoid using sharp objects or applying excessive force on the screen to prevent damage to the touch panel.

● Avoid overexposure: Avoid prolonged exposure of the touch screen to direct sunlight, as it may affect the display performance or cause overheating issues.

● Protective measures: In industrial or harsh environments, consider installing protective films, covers, or waterproof casings to enhance the durability and resistance to dirt of the touch screen.

● Avoid liquid contact: Prevent liquids from splashing onto the touch screen to avoid damaging the electronic components. Avoid placing liquid containers directly on the touch screen during use.

● Electrostatic discharge (ESD) precautions: For touch screens sensitive to static electricity, take appropriate ESD measures such as using anti-static cleaners and grounding devices.

● Follow operating guidelines: Adhere to the operation guidelines and user manuals provided for the touch product. Use and operate the touch features correctly to avoid accidental actions or unnecessary damage.
