Abstract

The utility model discloses a novel OGS (One Glass Solution) structure which comprises a transparent base material, a transparent conductive layer sputtered on the transparent base material, a transparent disapparation layer which eliminates ''etched grains'' and a printing ink layer around the transparent base material. A conductive material is communicated with a flexible printed circuit board (FPC) and the transparent conductive layer through the printing ink layer at one end and is fixed through a bonding layer. With the adoption of the technical scheme provided by utility model, the process flow of primarily sputtering the transparent conductive layer and then manufacturing the printing ink layer around is adopted. The printing ink needs not to bear high temperature when the transparent conductive layer is sputtered. Under the condition that original characteristics and advantages of the original OGS are maintained, the problem for conventional OGS structure that the material and process flow costs are high and the selectivity of the printing ink is single are solved, so that the novel OGS structure provided by the utility model has better market prospect.

Description

A kind of New O GS structure

Technical field

The utility model relates to the photoelectric display field, relates in particular to a kind of New O GS structure.

Background technology

Capacitive touch screen is market-oriented touch-screen of new generation after resistive touch screen, he has had qualitative leap by the product than previous generation on performance, not only be quick on the draw, and support multi-point touch, the playability of touch-control product and operability are improved greatly.And OGS (the one glass solution) product of a new generation is the new developing direction of capacitive touch screen, and from technological layer, the OGS technology is simple in structure than the G/G touch technology of present main flow, and is light, thin, light transmission is good; Owing to save a slice glass baseplate and bonding process, be beneficial to and reduce production costs, improve the product yield.

Traditional OGS structure, consult shown in Figure 1, generally be around transparent base 91, to lay ink lay 92, transparent base top sputter ITO layer 93, and be electrically connected with flexible PCB (PCF) 95 by anisotropic conductive film (ACF) 93, on manufacture craft, this traditional OGS structure all needs to make earlier the ink lay all around of transparent base, sputter ITO layer then, because the temperature of sputter ITO is higher relatively, reach temperature more than 200 ℃, therefore require ink lay to resist high temperature and nondiscolouring causes two problems like this: the one, printing ink need be selected high temperature resistance printing ink for use, and material and technological process cost raise; The 2nd, except black ink, other color inks all can't reach the high temperature resistance requirement at present.Therefore present traditional OGS scheme can't realize the application such as ink colors such as white, pink colours.

The utility model content

The purpose of this utility model is to provide a kind of New O GS structure at the deficiencies in the prior art, comprises transparent base, sputter transparency conducting layer, the transparent shadow layer that disappears of elimination " etching line ", the transparent base ink lay all around on transparent base.Conductive material sees through an end ink lay and is communicated with flexible PCB (FPC) and transparency conducting layer, fixes by bonding coat.

First sputter transparency conducting layer on the described New O GS structure fabrication flow process, ink lay around making then, ink lay can use traditional printing printing ink, common photoresist, comprises black and non-black photoresist.

The described transparent optional OC of shadow layer material, the SiO of disappearing ₂, Nb ₂O ₅And other transparent materials, the material refractive index is close with electrically conducting transparent layer material refractive index, the shadow layer that disappears can be selected to be coated on ink area and viewing area, the position is set on transparency conducting layer or below all can.

Described conductive material can be selected Metal Ball, material with carbon element or other conductive materials, except being coated on the lead-in wire electrode zone, also can be coated on part or whole ink area.

The optional glass of the material of described transparent base, PET, PC; Transparent conductive materials such as the optional ITO of the material of described transparency conducting layer, Nano Silver, the rare alkene of graphite; The optional epoxy resin of the material of described bonding coat, acryl resin and other bonding class materials.

A kind of New O GS structure described in the utility model, by setting up the layer of transparent shadow layer that disappears, the material that the selective refraction rate is close with the transparency conducting layer refractive index, eliminate " etching line " problem of ink area, and by lateral isolation conductive materials such as adding Metal Ball in printing ink, perhaps solved the conduction problem of lead-in wire electrode zone and FPC at the conductive material of horizontal conductings such as the electrode coating carbon slurry close with the printing ink color and luster, electrically conductive ink.Just can adopt first sputter transparency conducting layer thus, the technological process of ink lay around making then, high temperature when printing ink does not need to bear the sputter transparency conducting layer again, use traditional printing printing ink to get final product, under the situation that keeps original OGS primary characteristic and advantage, well solved material and technological process cost height, printing ink is selected the single problem that waits these traditional OGS structures to face, thereby has market outlook preferably.

Description of drawings

Utilize accompanying drawing to come the utility model is further detailed below, but the embodiment in the accompanying drawing does not constitute any restriction of the present utility model.
