The pen of the input pen is used to write f on the surface of the panel to create a smooth and slippery feeling on the surface of the panel. Those who feel good balance are the best. Among them, slippery feeling is particularly important. You can borrow the front end of the φ to make it look fine. Chu Yang A · Head, 丨 $ # 1 ^ The frictional resistance on the surface of the pen input device is good. The frictional resistance can be a slippery dynamic frictional resistance, and the static frictional resistance which is different from ": Tian, Tian Dan Jin Zhong r Zhi Baoyang Liuyi * 乂 'and Aida's slippery feeling at the beginning of writing." The control of friction resistance is extremely important. In addition, along with the slippery feeling, if the paper has the softness and depression, the pen writing feels better. And if it has the rough temperature feeling when writing on paper with Saki, the pen writing feeling is better. However, the conventional technology has not been based on the above three senses, and the writing feeling is still not satisfactory. The surface material of Patent Document 1 has a slippery feel due to the hard coating layer. The surface is not as meaningful as paper (texture). Problem of insufficient feeling of rough temperature. Patent Document 2 of / The surface is rough and rough, but the slippery feel is insufficient, and there is a problem of the surface material. The surface material of Patent Document 3 is not soft enough because of the soft person's depression feeling, but the slippery feeling is not enough. It is also because the surface has no texture. Although thin, there is a problem. There is a sense of coarse temperature, so the status quo is three types: slippery, concave and rough. ≪ Balanced, surface materials with good pen writing are still expected, especially good and very satisfactory Surface material: It is slippery.

2188-5474-PF (Nl); Tcshiau.ptd 200302775 V. Description of the invention (20) There is a feeling of depression, and the slippery feeling is also appropriate, so the comprehensive pen writing feeling is good. On the other hand, the slippery feel of all the comparative examples is not appropriate, and the rough feeling of the comparative example 1 is even more inadequate. In addition, in Comparative Example 2, the depression feeling was insufficient, and the writing feeling was not good. However, Comparative Example 3 had insufficient coarseness and was not good in writing. The above embodiment may be modified as follows. In order to improve the slippery feel, it is also possible to replace the polysiloxane compound with a fluorine-containing compound on the surface layer forming composition. Instead of providing an adhesive layer on the surface of the substrate, the surface material can be adhered to the front of the display with an appropriate adhesive.
