Working Principle: It belongs to the resistive touch screen technology. There are two flexible transparent conductive films with a small gap between them. When the screen is pressed, the upper and lower conductive films contact at the touch point, forming a closed circuit, and the resistance value at that point changes. The system accurately determines the touch point position by measuring this resistance change. The four corners of the touch screen are connected by four wires representing the x - axis and y - axis directions. The system applies a certain voltage to the two sets of wires to form a uniform voltage field. When a touch occurs, the system measures the voltage change through the x - axis and y - axis wires respectively to determine the position of the touch point on the x - axis and y - axis.
Operating Voltage: Usually operates at 5V DC, and some models may have a tolerance range of 4.5V - 5.5V.
Power Consumption: Generally low, probably in the range of a few hundred milliwatts to about 1 watt, depending on the specific design and whether there are additional features such as backlighting.
Resolution: It can reach 4096x4096 points, which allows for precise detection of touch positions on the screen.
Response Time: Typically within 10 - 20 milliseconds, ensuring that the user's touch operations can be quickly registered and processed.
Durability: It is designed to withstand a large number of touches. Generally, it can endure millions of touches, which is suitable for applications with frequent use.
Light Transmittance: Usually around 75% - 85%, which enables a significant amount of light from the underlying display to pass through, allowing the user to view the screen clearly.
Reflectance: The reflectance value is less than 5%, which helps to reduce glare and improve the readability of the screen, especially in bright environments.
Thickness: The thickness of the touch screen module is generally in the range of 2 - 5 millimeters, including protective layers and internal circuitry.
Surface Hardness: The surface hardness is at least 3H on the Mohs scale to resist scratches and abrasions during normal use.
Operating Temperature: The operating temperature range is generally - 20°C - 65°C, which allows the touch screen to function properly in a variety of indoor and some outdoor environments.
Storage Temperature: The storage temperature range is - 30°C - 70°C, which ensures that the touch screen can be stored safely in different environmental conditions.
