Description

technical field [0001] The invention relates to a protective cover and an electronic device using the protective cover. Background technique [0002] In order to enhance the convenience of operation, current mainstream electronic devices are usually equipped with a touch panel with a touch control function. The touch panel has a touch area and a frame area, the touch area is provided with touch electrodes, and the frame area is provided with transmission wires for providing electrical signals to the touch electrodes. In order to make the above-mentioned electronic device more beautiful, ink can generally be sprayed on the inner surface of the protective cover for protecting the touch panel corresponding to the frame area, so as to cover the internal structure of the electronic device such as transmission lines. [0003] As users have higher and higher requirements for appearance, the ink coated on the inner surface of the frame area of ​​the protective cover not only has a ...
