Abstract

An optical film includes a substrate, an absorption pattern and a scattering reflection layer. The substrate has a contact surface and a back surface opposite the contact surface, wherein the substrate allows a first light to pass and is made of a non-rigid material. The absorption pattern is arranged on the contact surface of the substrate to absorb the first light. The scattering reflection layer is arranged on the back surface of the substrate to scatter and reflect the first light to the contact surface of the substrate. The foregoing optical film enables an optical reader device to detect variations of the reflected first light, which is caused by deformation of the substrate, so that the corresponding force information can be obtained. A user input system including the foregoing optical film is also disclosed.

Description

【Technical field】 [0001] The invention relates to an optical film and a user input system, in particular to an optical film and a user input system for a user to input with a pen-type device. 【Background technique】 [0002] A user input system is provided on a substrate with a coding pattern containing addressing information, and the user uses a suitable reading device to decode the addressing information in the coding pattern to record the trajectory of the reading device moving on the substrate surface. Generally speaking, the reading device is a pen-shaped structure, so that the user can interact with the electronic device in a habitual writing method. Although the above-mentioned user input system can decode the addressing information to record the track, it cannot obtain the contact force between the reading device and the substrate, thus limiting the application range of this type of user input system. [0003] In view of this, how to obtain information on the force o...
