Abstract

In the present invention, the base material in the conductive film includes an integrally formed first part and a second part, the first part includes a touch sensing area and a frame area, and the second part extends outward from at least one side of the first part At least one flexible connection part is formed, and the sensing electrode leads and the driving electrode leads are respectively extended to the ends of each flexible connection part to form a first plug-in structure and a second plug-in structure containing electrode leads, so as to form a plug-in type structure, so that it is not necessary to bind an additional flexible printed circuit board on the touch sensing layer when it is connected with the main board or other components through a connector, so it is unnecessary to use expensive flexible printed circuit boards and avoid flexible printed circuit boards. Poor contact and poor reliability of subsequent samples are likely to occur during the bonding process between the circuit board and the touch sensing layer.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a conductive film that does not need to be bound to a flexible printed circuit board and a touch screen. Background technique [0002] With the advancement of science and technology, electronic products with touch screens have spread to every corner of human society. At present, in some electronic products containing touch screens or touch sensing modules, a flexible printed circuit board (Flexible printed circuit board, referred to as FPCB) is usually used to connect the touch sensing layer (Sensor layer) with the main board or other components in the electronic product. Electrical connection: One end of the FPCB is connected to the main board or other components of the electronic product by means of plugging or snapping through the connector, and the other end is connected to the Sensor touch sensor through Anisotropic Conductive Film (ACF) Binding (also known as Bonding). [000...
