Capacitive touch screen with gf1 structure and manufacturing method thereof

Abstract

The invention discloses a capacitive touch screen of a GF1 (Glass Film) structure, and a manufacture method of the capacitive touch screen. The capacitive touch screen of the GF1 structure comprises an ITO (Indium Tin Oxide) film layer and a flexible circuit board, wherein the ITO film layer is provided with an X-direction ITO circuit and a Y-direction ITO circuit, wherein the X-direction ITO circuit and the Y-direction ITO circuit are in integral forming; the X-direction ITO circuit comprises an X-direction ITO electrode wire and a X-direction ITO outgoing wire, wherein the X-direction ITO electrode wire and the X-direction ITO outgoing wire are in integral forming; the Y-direction ITO circuit comprises a Y-direction ITO electrode wire and a Y-direction ITO outgoing wire, wherein the Y-direction ITO electrode wire and the Y-direction ITO outgoing wire are in integral forming; and the X-direction ITO outgoing wire and the Y-direction ITO outgoing wire are connected with the flexible circuit board. The capacitive touch screen does not need to manufacture a silver paste wire to connect the ITO electrode wire and the flexible circuit board, so that the registering problem of the ITO wire and the sliver paste wire is avoided. The capacitive touch screen has the advantages of simple structure, high manufacture precision and high finished product yield and can save manufacture cost.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a capacitive touch screen with a GF1 structure and a manufacturing method thereof. Background technique [0002] In the existing capacitive touch screen manufacturing process, after the ITO circuit is made on the ITO film (ie, ITO Film), it needs to be processed into silver glue line through silver paste to realize the connection between the ITO circuit and the FPC, and then the circuit connection can be realized. The use of silver glue wires to connect ITO lines and FPC has the following disadvantages: (1) The cost is high. The cost of domestic silver glue is basically 5000RMB / KG, while the cost of imported silver glue is tens of thousands of yuan / KG. (2) The processing technology of silver glue line is complicated, the yield rate is low and the life efficiency is low. No matter the processing of the existing silver glue line adopts direct printing, or uses laser laser or...

Problems solved by technology

The use of silver glue wires to connect ITO lines and FPC has the following disadvantages: (1) The cost is high. The cost of domestic silver glue is basically 5000RMB / KG, while the cost of imported silver glue is tens of thousands of yuan / KG

(2) The processing technology of silver glue line is complicated, the yield rate is low and the life efficiency is low

No matter the processing of the existing silver glue line adopts direct printing, or uses laser laser or exposure and development after printing, the processing technology basically needs 2 to 5 processes, and the good product rate is basically only about 95%.

(3) The silver glue line is opaque, and it is difficult to achieve a narrow frame or even a frameless design
