Abstract
The invention discloses a light, thin and low-cost capacitive touch panel for a touch screen. The capacitive touch panel comprises a tempered white glass plate, wherein an indium tin oxide (ITO) coating layer is arranged on one surface of the white glass plate; and the ITO coating layer is composed of a group of ITO lines arranged at intervals. According to the invention, ITO coating is directly performed on the white glass single side, and then the ITO coating layer is etched to obtain the ITO lines. A gluing process is omitted, gluing material is saved, and the technical difficulty is lowered; as the etching can be performed by use of a common LCD (liquid crystal display) production line, the production cost is relatively low; and the lines are directly etched on the coating layer and the touch panel is light and thin.
Description
Technical field
The invention belongs to the capacitance type touch-control panel technical field, especially relate to a kind of jamproof single glass capacitance type touch-control panel and preparation method thereof.
Background technology
Along with the development of capacitance type touch-control panel, light, thinly become a kind of trend.And people are also increasingly high to the requirement of cost.In order to satisfy client's above demand; A lot of contact panel merchants begin to consider exploitation single glass (one glass) capacitive touch screen; Be about to touch controllable function glass (ITO sensor) and directly be made on the tempered glass, save the thickness of touch controllable function glass 0.5mm or 0.55mm and the optical glue 0.1mm left and right thickness of applying.At present, capacitance type touch-control panel structure commonly used is as shown in Figure 3, comprises the optical glue 33 and the FPC (FPC) 34 of tempered glass 31, touch controllable function glass 32, applying usefulness.The structure of the capacitive touch screen of existing single glass is as shown in Figure 4, comprises tempered glass 21, the FPC 22 of etching ITO.Because of single glass capacitance type touch-control panel saves thickness and the optical glue thickness of 0.5mm or 0.55mm, single glass contact panel and liquid crystal display module through port word glue or optical glue are directly fitted.Induction line and liquid crystal display module distance generally have only the thickness 0.1mm～0.175mm of mouthful word glue or optical glue.And single glass plates SiO behind etching ITO film
2Protective seam plates screen layer again, and this technology difficulty is higher, yield is low.General technology can save plating screen layer technology.At this moment, interference problem occurs thereupon.Interference problem becomes the big obstacle that single glass contact panel advances.
One Chinese patent application 201110053844.9 like the applicant; A kind of contact panel and manufacturing approach thereof of capacitive touch screen are disclosed; The one side of said substrate comprises nesa coating; Comprise many induction electric conduction routing on the said nesa coating, each is responded between the electric conduction routing and carries out the interval through etched voids.The contact panel method for making of said capacitive touch screen may further comprise the steps: at the one side plating layer of transparent conducting film of contact panel substrate; The described nesa coating of photoetching, and etch many induction electric conduction routing, carry out the interval through etched voids between the induction electric conduction routing, form the single face pattern.Also like the method for making of disclosed a kind of frivolous, the low cost capacitive touch screen contact panel of one Chinese patent application 201110244511.4; The white glass plate that comprises tempering; Directly on the white glass single face, carry out indium oxide coating; To indium oxide coating layer etch processes, etch tin indium oxide (ITO) circuit again.
Therefore be necessary to propose a kind of jamproof solution, be intended to a kind of simply, way solves the interference to contact panel of liquid crystal display module that single glass capacitance touching control panel in use exists cheaply.
Summary of the invention
The purpose of this invention is to provide a kind of jamproof single glass capacitance type touch-control panel, solve of the interference of the liquid crystal display module of existing single glass capacitance type touch-control panel contact panel, and low-cost.
The further purpose of purpose of invention provides a kind of method for making of jamproof single glass capacitance type touch-control panel.
The technical solution adopted for the present invention to solve the technical problems is:
