Touch Panel

Touchscreen connections can be made using USB, I2C, or Type-C.

  • USB and Type-C connections are simple and convenient, suitable for most PCs and tablets.
  • I2C connection is commonly used in embedded applications, especially for eDP touchscreen screens.

When choosing a touchscreen, it is important to consider the requirements of the device and the intended application scenario in order to choose the appropriate connection method.

The USB connection is a common method for connecting a touchscreen, known for its simplicity, convenience, and wide compatibility. Most personal computers and tablets support USB interfaces, making it suitable for these devices. USB connection typically utilizes the USB HID (Human Interface Device) protocol for communication, enabling basic touchscreen functionality.

The I2C connection is a serial communication protocol commonly used for embedded devices. In the context of touchscreens, the I2C connection is often employed for connecting eDP (Embedded DisplayPort) touchscreen screens. Compared to USB connection, I2C has a lower transmission rate but is more prevalent in embedded applications. Selecting an I2C connection usually requires considering factors such as device power consumption and space limitations.

The Type-C connection is a versatile and comprehensive standard that supports various protocols and functions, including USB, DisplayPort, and Power Delivery. Opting for a Type-C connection is typically suitable for scenarios that demand both data transfer and power charging capabilities simultaneously, such as high-performance tablets and mobile devices.
