Due to the development of the digital industry, the IoT era is coming, in which all electronic systems are connected by using mobile phones from kindergarteners to the elderly.

In the case of a mobile phone, it is generally composed of inputting necessary information using a capacitive touch sensor as an input device, but in general, a mobile phone (with a digitizer) has a limited size, that is, 6 inches (display screen) or less, There is a limit to entering text. Therefore, although a tablet PC is used for a large screen, it is inconvenient to carry both products.

Recently, large-screen tablet PCs have been popularized, and many students and office workers use them. However, they have a large screen, so they are heavy, so it is inconvenient to carry and the screen is easy to break. Accordingly, there is a demand for a portable touch input device that is light in weight and capable of preventing the screen from being broken.
