Abstract

The invention discloses a single-layer projected capacitive touch panel and a manufacturing method thereof. The touch panel comprises a glass cover plate, a touch induction circuit layer, an insulated ink layer, a lead layer, an insulating layer and a conductive glue layer, wherein the touch induction circuit layer, the insulated ink layer, the lead layer, the insulating layer and the conductive glue layer are sequentially arranged on a circuit surface of the glass cover plate; and the insulated ink layer covers the edge of the touch induction circuit layer, a plurality of through grooves are formed on the insulated ink layer, the conductive layer is filled in each through groove and electrically connected with the lead layer and the touch induction circuit layer, a flexible printed circuit board can be fixed by the conductive glue layer and electrically connected with the lead layer through the conductive glue layer. Only single-layer glass is used in the touch panel, so the touch panel has the advantages of good transmittance, low thickness, low cost and the like.

Description

technical field [0001] The invention relates to a projected capacitive touch panel and a manufacturing method thereof, in particular to a single-layer projected capacitive touch panel using only a single layer of glass and a manufacturing method thereof. Background technique [0002] With the evolution and development of touch technology, many consumer electronic products save the space occupied by input and control interfaces, making the application of touch panels more and more common, such as personal digital assistants (PDA) or global satellite positioning systems (GPS) and other portable electronic products. [0003] Before the release of the iPhone, resistive touch panels became the preferred display and input interface for small hand-held electronic products (such as mobile phones) due to their mature technology and low manufacturing cost, but there are still problems in how to achieve multi-touch However, after the release of the iPhone, the projected capacitive tou...
