Abstract

The invention relates to a manufacturing method of a flexible film function piece. The manufacturing method includes a cutting step, a gluing step, a conventional machining step, a UV irradiation step and a separating, cutting and binding step, wherein in the cutting step, a transparent conducting film and a UV glue are cut into the size being consistent with the size of a transparent base plate respectively; in the gluing step, the transparent conducting film is stuck to the transparent base plate by means of the UV glue to form a semi-finished product; in the conventional machining step, a predetermined circuit is formed on the transparent conducting film; in the UV irradiation step, a UV lamp is used for irradiating a machined product so as to enable adhesiveness of the UV glue to be reduced; in the separating, cutting and binding step, the transparent conducting film with the predetermined circuit is removed from the transparent base plate, and at last, cutting and binding are conducted to obtain a finished flexible film function piece. According to the manufacturing method, the sheet of the transparent conducting film is stuck to the transparent base plate, subsequent machining procedures can be conducted conveniently, the defect that processing is difficult due to the fact that the transparent conducting film is soft relatively is overcome, after machining is completed, the flexible film function piece can be removed from the transparent base plate conveniently, and the manufacturing efficiency and the product yield are high.

Description

technical field

[0001] The invention relates to the technical field of touch screens, in particular to a method for manufacturing a flexible film functional sheet. Background technique

[0002] Flexible thin film (film) functional sheet is one of the core components of capacitive touch screens, and will also be one of the key components of future flexible display devices. The thin film functional sheet is based on a flexible transparent conductive film, including ITO film, nano-silver film and graphene film. It is processed into a functional sheet through certain process steps, and then connected to the circuit to have a touch function. The main production methods of the existing flexible thin film functional sheets include: screen printing production method, laser etching method and winding yellow light production method.

[0003] The screen printing production method is to print acid-resistant ink or ITO etching paste on a piece of pre-cut ITO film sheet through screen pr...
