Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to an OGS touch screen and electronic equipment. Background Art

[0002] OGS (One Glass Solution) touch screen is an electronic product protection screen made by directly forming an ITO conductive film and a sensor on the protective glass. A piece of glass plays the dual role of protective glass and touch sensor. It has the following advantages: simple structure, light, thin, good light transmittance, and because it saves a piece of glass substrate and bonding process, it reduces production costs and improves product qualification rate, so it is widely used in various fields.

[0003] The current production order of OGS touch screens is BM layer, shadow elimination layer, first ITO layer, first OC insulating layer, second ITO layer, MoAlMo film layer, second OC insulating layer and silicon dioxide layer, which are made on the glass substrate in sequence. Among them, the second OC insulating layer is generally a whole-surface coating. Since the second OC insulating layer itself absorbs water, if it absorbs water, it will easily cause the MoAlMo film layer in contact with it to be oxidized, which will not only affect the performance of the MoAlMo film layer, but also reduce the adhesion between the second OC insulating layer and the MoAlMo film layer, thereby affecting the quality of the touch screen.

[0030] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix", "set" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] First, see Figure 1 The present invention provides an OGS touch screen, comprising: a substrate 100, and a BM layer 110, a first ITO layer 120, a first OC insulating layer 130, a second ITO layer 140, a MoAlMo layer 150, a silicon dioxide layer 160 and a second OC insulating layer 170 sequentially arranged on the substrate 100 from bottom to top, wherein the silicon dioxide layer 160 is used to isolate water vapor in the air to ensure the stability of the MoAlMo layer.

[0032] The technical solution of the embodiment of the utility model is to exchange the manufacturing order of the second OC insulating layer and the silicon dioxide layer in the traditional OGS touch screen, so that the silicon dioxide layer protects the MoAlMo layer. Compared with the second OC insulating layer that easily absorbs water, the silicon dioxide layer directly protects the MoAlMo layer, which can isolate water vapor in the air to ensure the stability of the MoAlMo layer, and further use the second OC insulating layer for full coverage insulation protection, thereby further improving the protection of other film layers and improving the performance of the OGS touch screen.

[0033] In the embodiment of the present utility model, reference Figure 2 The BM layer 110 is a frame ink pattern layer arranged in the non-display area, and the interior of the frame is the display area of ​​the touch screen; the first ITO layer 120 is an ITO bridge structure in the ITO touch structure; the second ITO layer 140 is an ITO pattern layer in the ITO touch structure; the first OC insulating layer 130 is used to isolate the first ITO layer 120 and the second ITO layer 140, that is, to isolate the overlapping part of the ITO bridge structure and the ITO pattern layer to avoid short circuit between the two. In addition, the first OC insulating layer 130 only partially covers the first ITO layer 120, so that the first ITO layer 120 can still connect to the second ITO layer 140. The MoAlMo layer 150 is a metal wiring layer, which is arranged on the non-display area of ​​the touch screen and is connected to the second ITO layer 140. In addition, the MoAlMo layer 150 also includes a binding position, which is exposed and can be connected to an FPC or the like in the future; the silicon dioxide layer 160 directly protects the MoAlMo layer 150, which can isolate water vapor in the air to ensure the stability of the MoAlMo layer; the second OC insulating layer 170 further performs full coverage insulation protection, further improves the protection of other film layers, and improves the performance of the OGS touch screen.

[0034] As a preferred embodiment of the present invention, refer to Figure 3-4 , the silicon dioxide layer 160 includes a full coverage area 161 and a half coverage area 162;

[0035] The full coverage area 161 covers the MoAlMo layer 150 and the bridge point area 200 between the first ITO layer 120 and the second ITO layer 140;

[0036] The semi-covering area 162 includes a plurality of through holes 163 , so that the second OC insulating layer 170 is in contact with the second ITO layer 140 through the plurality of through holes 163 .

[0037] Wherein, when the MoAlMo layer includes a binding site, the binding site should remain exposed, and the silicon dioxide layer should be arranged to avoid the binding site. Since the adhesion between the second OC insulating layer 170 and the silicon dioxide layer 160 is poor, through the above arrangement, the second OC insulating layer 170 can adhere to both the silicon dioxide layer 160 and the second ITO layer 140, thereby enhancing the adhesion of the second OC insulating layer 170.

[0038] As a preferred embodiment of the present invention, refer to Figure 5 A shadow elimination layer 180 is further provided between the BM layer 110 and the first ITO layer 120. The provision of the shadow elimination layer 180 can greatly avoid poor display phenomena, such as the shadow problem caused by the substrate, the first ITO layer or the second ITO layer, and improve the quality and display effect of the touch screen.

[0039] As a preferred embodiment of the present invention, refer to Figure 6 , an AR coating layer 190 is further provided between the BM layer 110 and the substrate 100. In the embodiment of the utility model, vacuum sputtering coating can be performed on the substrate 100 to coat a layer of niobium oxide as an oxide film layer for eliminating etching lines, thereby forming the AR coating layer 190, thereby achieving the purpose of eliminating etching lines and improving the display quality of the touch display screen.

[0040] As a preferred embodiment of the present invention, refer to Figure 7 The OGS touch screen further includes a cover plate 300, and the cover plate 300 is disposed on the second OC insulating layer 170. The cover plate is preferably a tempered glass cover plate, thereby improving the strength of the touch display screen.

[0041] As a preferred embodiment of the present invention, refer to Figure 7 A silk screen ink layer 310 is provided on one side of the cover plate 300 close to the second OC insulating layer 170 .

[0042] As a preferred embodiment of the present invention, refer to Figure 7The cover plate 300 and the second OC insulating layer 170 are bonded together by OC optical adhesive 400. OCA optical adhesive has the characteristics of being colorless, transparent and having good bonding strength, and can ensure that the cover plate is bonded more stably.

[0043] As a preferred embodiment of the present invention, one or more of an anti-peep film layer, an AG film layer or an AF film layer is provided on the side of the cover plate away from the second OC insulating layer, so that the OGS touch screen in the present invention has good anti-peep function or good anti-glare, anti-fingerprint, high definition and other effects, and improves the display quality of the OGS touch screen.

[0044] As a preferred embodiment of the present invention, the substrate 100 is a glass substrate or a PMMA substrate.

[0045] In a second aspect, an embodiment of the present utility model further provides an electronic device, comprising the OGS touch screen in any embodiment of the present utility model.
