Introduction
The increasing popularity of capacitive touch screens in large sizes such as 55 inches is attributed to their superior touch sensitivity and multi-touch capabilities. This article provides a detailed analysis of how these touch screens function, with a focus on the specific innovations and solutions provided by Hangzhou Grahowlet Technology Co., Ltd.
Principle of Operation
Capacitive touch screens function based on the electrical properties of the human body. The screen is coated with a transparent conductor. When a user touches the screen, it alters the local electrostatic field, which is interpreted by the screen's controller to determine the touch location.
Working Mechanism
Most modern capacitive touch screens use mutual capacitance, where a grid of conductive layers senses changes in capacitance when touched. The 55-inch screen typically has a resolution of approximately 3840x2160 pixels, enabling precise touch detection.
Advantages
- Multi-touch capability allows for complex gestures.
- High sensitivity provides responsiveness even to light touches.
- Durability due to the absence of moving parts.
Technical Specifications
A typical 55-inch capacitive touch screen might have the following technical specifications:
- Touch Points: Up to 10 simultaneous touches.
- Resolution: 3840x2160 pixels.
- Touch Accuracy: +/- 2mm.
- Response Time: Less than 10 ms.
- Interface: USB, I2C, or RS232.
- Surface Hardness: ≥6H for enhanced durability.
