Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings.
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.
As used herein, the singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. As used herein, the term "and/or" includes all or any element and all combinations of one or more of the associated listed items.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
The inventor analyzes the structure of the binding region of the existing flexible touch screen, and finds that the problem of poor adhesion exists between the Metal and the base material. The Metal is easy to separate from the base material, so that the FPC drawing force in the Bonding area is insufficient; in other words, when the FPC is pulled with a large force, the Metal is likely to be separated from the substrate.
Therefore, the inventor of the invention considers that an ITO layer is added between the flexible substrate and the Metal to solve the problem of poor adhesion between the Metal and the substrate, so that the FPC drawing force of a Bonding area of the flexible touch screen is enhanced, and the quality of the flexible touch screen is ensured.
The technical scheme of the invention is described in detail below with reference to the accompanying drawings, and two embodiments are specifically provided in the technical scheme of the invention.
Example one
The structure of the flexible touch screen binding area provided by the first embodiment of the present invention, as shown in fig. 2, includes: a flexible base 201 as a substrate, and a first ITO layer 202, a metal layer 203, an OC layer 204, and a second ITO layer 205 which are sequentially disposed on the flexible base 201.
The OC layer 204 is provided with a via hole, and the second ITO layer 205 is connected to the metal layer 203 through the via hole. As a preferred embodiment, the aperture of the via hole of the OC layer (insulating layer) covering the metal layer is larger than the set first aperture; the through hole of the OC layer covering the flexible substrate is smaller than the set second aperture; wherein the second aperture is smaller than the first aperture.
The method for manufacturing the binding area of the flexible touch screen provided by the embodiment of the invention has the flow shown in fig. 3, and comprises the following steps:
step S301: and depositing an ITO layer on the flexible substrate and etching to obtain a pattern of the first ITO layer.
In the step, an ITO layer is deposited and etched on the flexible substrate in a one-step composition process, and a graph of the first ITO layer is obtained. For example, the resulting first ITO layer is patterned as shown in FIG. 4, where a plurality of first ITO sub-blocks are arranged in an array on a flexible substrate.
Step S302: depositing a metal layer on the flexible substrate and etching to obtain a pattern of the metal layer on the first ITO layer;
in the step, a metal layer is deposited and etched on the flexible substrate in a one-step composition process, and a pattern of the metal layer on the first ITO layer is obtained. For example, as shown in fig. 2, a metal sheet is deposited on each first layer ITO sub-block, that is, the metal layer includes several metal sheets respectively laid on each first layer ITO sub-block.
Because a layer of ITO is added between the Metal (Metal) layer and the base material, the ITO has strong adhesive force with the base material, and the Metal has strong adhesive force with the ITO, the problem of poor adhesive force between the Metal and the base material is solved, the FPC drawing force of a Bonding area of the flexible touch screen can be enhanced, and the quality of the flexible touch screen is ensured.
Preferably, the area of the first layer of ITO subblocks may be larger than the area of the metal layer laid above the first layer of ITO subblocks, that is, the boundary of the first layer of ITO subblocks below the metal sheet extends beyond the boundary of the metal sheet; so that stronger adhesive force is formed between the ITO and the base material, and the FPC drawing force of a Bonding area of the flexible touch screen is further enhanced. For example, the first layer of ITO sub-blocks is expanded to about 2um each on the two sides of the length and the width of the Metal laid on the first layer of ITO sub-blocks. And Metal Bonding W/S (Metal Bonding area width/spacing) is 100/100 um.
Step S303: and depositing an insulating layer on the flexible substrate and etching the via hole to obtain a graph of the OC layer with the via hole.
In the step, an OC layer is deposited and etched on the flexible substrate in a one-step composition process, and a graph of the OC layer with the through holes is obtained. For example, as shown in FIG. 2, the OC layer can be applied over both the metal layer and the flexible substrate without the metal layer applied.
Step S304: depositing an ITO layer on the flexible substrate and etching to obtain a pattern of a second ITO layer; the second ITO layer is connected with the metal layer through the via hole of the OC layer.
In the step, an ITO layer is deposited and etched on the flexible substrate in a one-step composition process, and a pattern of a second ITO layer is obtained. As shown in fig. 2, the second ITO layer is connected to the metal layer through the via of the OC layer.
In practical applications, the inventor of the present invention has also found that, in the prior art, when a Bonding area is fabricated, an ITO film is directly bonded to a Metal, since the Metal is thicker, about 1500-2000A, and the ITO film is thinner, about 500A, as shown in fig. 1, the ITO film is prone to form cracks at the edge of the Metal, and the Metal cannot be effectively protected, and is prone to corrosion when exposed to air, thereby causing insufficient pulling force in the Bonding area.
Therefore, in the technical scheme of the first embodiment of the invention, the middle layer OC layer is added in the Bonding area, and the second ITO layer is overlapped with the Metal in a sinking mode, so that the problem that the Metal is difficult to effectively protect due to the fact that the second ITO layer is directly overlapped with the Metal to generate cracks is avoided, and the drawing force of the Bonding area is further enhanced.
Preferably, the aperture of the via OC1 of the OC layer overlying the metal layer may be relatively large to facilitate electrical conduction from the metal layer to the second ITO layer. For example, the aperture of via OC1 of the OC layer above the metal layer may be larger than the set first aperture. For example, a first aperture of 30um is set, and the aperture of via OC1 of the OC layer overlying the metal layer can be set to 35 um.
The aperture of the via hole of the OC layer covering the flexible substrate, that is, the via hole OC2 of the OC layer laid between the metal sheets can be smaller, so as to increase the contact area between the ACF (anisotropic conductive adhesive) and the Bonding area, further enhance the FPC pull force, and improve the reliability. For example, the via OC2 of the OC layer covering the flexible substrate is smaller than the set second aperture; wherein the second aperture is smaller than the first aperture. For example, the second aperture is set to 20um, and the aperture of the via OC2 of the OC layer covering the flexible substrate can be set to 15 um.
As shown in fig. 2, the second ITO layer may include a plurality of second ITO sub-blocks respectively located above the metal sheets; preferably, the area of the second layer of ITO sub-blocks above the metal sheet may be larger than the area of the first layer of ITO sub-blocks below the metal sheet, that is, the boundary of the second layer of ITO sub-blocks above the metal sheet extends beyond the boundary of the first layer of ITO sub-blocks below the metal sheet. In this way, the second layer of ITO sub-blocks can protect the metal sheet below the second layer of ITO sub-blocks and the first layer of ITO sub-blocks.
In the technical scheme of the first embodiment of the invention, the ITO priming is added between the flexible substrate and the Metal, so that the problem of poor adhesive force between the Metal and the substrate is solved, the FPC drawing force of a Bonding area of the flexible touch screen can be enhanced, and the quality of the flexible touch screen is ensured.
Furthermore, in the technical scheme of the first embodiment of the invention, the middle layer OC layer is added in the Bonding area, and the second ITO layer is overlapped with the Metal in a sinking mode, so that the problem that the Metal is difficult to effectively protect due to the fact that the second ITO layer is directly overlapped with the Metal to generate cracks is avoided, and the drawing force of the Bonding area is further enhanced.
Further, in the first technical solution of the embodiment of the present invention, the aperture ratio of the via hole OC1 of the OC layer covering the metal layer is relatively large, so that the metal layer is electrically conducted to the second ITO layer; meanwhile, the through hole of the OC layer covering the flexible substrate is smaller, so that the contact area of the ACF and the Bonding area is increased, and the drawing force of the FPC is further enhanced.
Example two
A simpler flexible touch screen binding region structure provided by the second embodiment of the present invention, as shown in fig. 5, includes: a flexible base 501 as a substrate, and a first ITO layer 502, a metal layer 503, and a second ITO layer 505 sequentially disposed on the flexible base 501.
The first ITO layer 502 includes a plurality of first ITO sub-blocks arranged in an array on the flexible substrate; the metal layer 503 comprises a plurality of metal sheets which are respectively paved on the first layer of ITO subblocks; the second ITO layer 505 includes a plurality of second ITO sub-blocks respectively laid on the metal sheets of the metal layer 503 and covering the metal sheets and the first ITO sub-blocks under the metal sheets.
The manufacturing method of the binding area of the flexible touch screen provided by the second embodiment of the invention has a process shown in fig. 6, and comprises the following steps:
step S601: an ITO layer is deposited on the flexible substrate and etched to obtain a pattern of the first ITO layer 502.
In this step, an ITO layer is deposited and etched on the flexible substrate in a one-step patterning process to obtain a pattern of the first ITO layer 502. The resulting first ITO layer 502 may include a first layer of ITO sub-blocks arranged in an array on a flexible substrate.
Step S602: and depositing a metal layer on the flexible substrate and etching to obtain a pattern of the metal layer 503 on the first ITO layer 502.
In this step, a metal layer is deposited and etched on the flexible substrate in a one-step patterning process to obtain a pattern of the metal layer 503 on the first ITO layer 502. The metal layer 503 may include a plurality of metal sheets, which are respectively laid on the first ITO sub-blocks.
Because a layer of ITO is added between the Metal (Metal) layer and the base material, the ITO has strong adhesive force with the base material, and the Metal has strong adhesive force with the ITO, the problem of poor adhesive force between the Metal and the base material is solved, the FPC drawing force of a Bonding area of the flexible touch screen can be enhanced, and the quality of the flexible touch screen is ensured.
Preferably, the area of the metal sheet of the metal layer 503 may be smaller than the area of the first layer ITO sub-block under the metal sheet, that is, the boundary of the first layer ITO sub-block under the metal sheet of the metal layer 503 extends beyond the boundary of the metal sheet. So that the first layer of ITO subblock has stronger adhesive force with the base material, and the FPC drawing force of the Bonding area of the flexible touch screen is further enhanced.
Step S603: and depositing an ITO layer on the flexible substrate and etching to obtain a pattern of a second ITO layer 505 covering the first ITO layer 502 and the metal layer 503.
In this step, a layer of ITO is deposited and etched on the flexible substrate in a one-step patterning process to obtain a pattern of the second ITO layer 505. The second ITO layer 505 may include a plurality of second ITO sub-blocks, which are respectively laid on the metal sheets of the metal layer 503 and cover the metal sheets and the first ITO sub-blocks under the metal sheets.
Preferably, the area of the second layer of ITO sub-blocks is larger than the area of the first layer of ITO sub-blocks of the first ITO layer 502 below it, i.e., the boundaries of the second layer of ITO sub-blocks extend beyond the boundaries of the first layer of ITO sub-blocks below it. In this way, the second layer of ITO sub-blocks can protect the metal sheet below the second layer of ITO sub-blocks and the first layer of ITO sub-blocks.
In the second technical scheme of the embodiment of the invention, the ITO priming is added between the flexible substrate and the Metal, so that the problem of poor adhesive force between the Metal and the substrate is solved, the FPC drawing force of a Bonding area of the flexible touch screen can be enhanced, and the quality of the flexible touch screen is ensured.
The flexible touch screen provided by the invention can comprise the Bonding area in the first embodiment or the second embodiment.
According to the technical scheme, the ITO priming is added between the flexible substrate and the Metal, so that the problem of poor adhesion between the Metal and the substrate is solved, the FPC drawing force of a Bonding area of the flexible touch screen can be enhanced, and the quality of the flexible touch screen is ensured.
Furthermore, an OC layer as an intermediate layer is additionally arranged in the Bonding area, and the second ITO layer is connected with the Metal in a sinking mode, so that the problem that the Metal is difficult to effectively protect due to the fact that the second ITO layer is directly connected with the Metal in a lap joint mode and cracks are generated is solved, and the drawing force of the Bonding area is further enhanced.
Further, the aperture ratio of the via hole OC1 of the OC layer covering the metal layer is larger, so that the metal layer is conductive to the second ITO layer; meanwhile, the through hole of the OC layer covering the flexible substrate is smaller, so that the contact area of the ACF and the Bonding area is increased, and the drawing force of the FPC is further enhanced.
