1. General Information


  • Size: Without further data, it's hard to determine the exact size. However, the touch glass could be designed for a specific device with a corresponding display size. It might have a standard aspect ratio like 16:9 or 4:3 depending on the application.

  • Type: It could be a capacitive or resistive touch glass. Capacitive touch glass is widely used for its multi-touch capabilities and smooth operation, while resistive touch glass is known for its durability and lower cost in some cases.


2. Touch Performance


  • Resolution: For touch sensing, it could have a high resolution to accurately detect touch positions. A common touch resolution for modern touch glasses is in the range of 4096 x 4096 points, allowing for precise touch input.

  • Response Time: A good touch glass usually has a short response time, typically less than 20 milliseconds. This ensures that the user's touch is registered quickly, providing a seamless user experience.

  • Touch Points: If it's a capacitive touch glass, it might support multiple touch points, such as 10-touch points, enabling more complex touch interactions like pinch-to-zoom and multi-finger gestures.


3. Optical Properties


  • Transmittance: High light transmittance is crucial for a touch glass. A typical value could be around 90% or higher, ensuring that the underlying display can be clearly seen through the glass.

  • Reflectance: Low reflectance is desired to reduce glare and improve visibility, especially in bright environments. A reflectance value of less than 5% is common for quality touch glasses.


4. Physical Properties


  • Thickness: The thickness of the touch glass could be in the range of 0.5 to 2 millimeters. Thinner glasses are often preferred for a sleeker design, while thicker glasses may offer more durability.

  • Hardness: The surface of the touch glass might have a hardness rating of at least 3H on the Mohs scale to resist scratches and abrasions during normal use.


5. Electrical Properties (if applicable for capacitive touch glass)


  • Operating Voltage: Capacitive touch glasses usually operate within a low voltage range, such as 3.3V or 5V DC. The power consumption is relatively low, typically in the range of a few hundred milliwatts.


6. Environmental Specifications


  • Operating Temperature: It might be designed to operate within a temperature range of -20°C to 70°C for general-purpose applications. Industrial-grade touch glasses may have a wider operating temperature range.

  • Storage Temperature: The storage temperature range could be -30°C to 80°C, allowing for safe storage in various environmental conditions.
