Background

A typical watch includes a case and two straps attached to the case. The strap is typically made of a soft material that allows the user to attach the watch to the wrist. In the past, liquid crystal displays were equipped with a hard case because the liquid crystal display could not be bent. In order to match the curvature of the wrist, the surface area of the liquid crystal display should not be too large, otherwise the user may wear discomfort. Therefore, the area of the liquid crystal display has been limited for a long time, and the small display area not only affects the display angle, but also limits the size and number of characters or images.

In addition, the traditional watch mostly uses a buckle to attach the watch to the wrist, which is not only inconvenient to wear or remove, but also the adjustment of the length of the strap is often subject to the through hole in the strap, and it is difficult to fully match the thickness of the wrist of the user.

Moreover, for other displays or stationery provided with a liquid crystal display, since the liquid crystal display cannot be bent, the design of the product is limited.
