Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of liquid crystal display, and more specifically, to a smart wearable watch with a drilled screen. Background Art
[0002] With the advancement of smart technology, smart wearable watches have become a necessity in people's lives. Currently, conventional smart wearable watches use virtual hands instead of traditional mechanical hands, but some consumers still prefer mechanical hands. The combination of conventional smart watches and traditional mechanical hands is a new development trend, which not only retains the high-end and elegant hands design, but also realizes intelligent touch display.
[0003] The TP touch panel layer and the perforated screen of these smart wearable watches are typically bonded together using optical adhesive. The TP touch panel is typically a single-layer solution, and both the optical adhesive and the TP touch panel are relatively thin, with a typical maximum thickness of only 275µm. This makes it difficult to remove the optical adhesive backing film during screen bonding, and can also cause micro-fractures in the ITO layer on the TP touch panel during removal, impairing functionality. Utility Model Content
[0004] The technical problem to be solved by the present invention is how to make the back film of the optical adhesive easy to tear without damaging the ITO on the TP touch layer, thereby avoiding damage to the function.
[0005] The technical problem to be solved by the present invention is achieved through the following technical solutions:
[0006] In order to solve the above technical problems, the utility model provides a drilled screen smart wearable watch, which includes a watch cover, a pointer layer, a TP touch layer, a non-functional layer and a drilled screen, wherein the pointer layer is arranged below the watch cover; the TP touch layer is arranged below the pointer layer; the non-functional layer is arranged below the TP touch layer, and a first optical adhesive layer is arranged between the non-functional layer and the TP touch layer; the drilled screen is arranged below the non-functional layer, and a second optical adhesive layer is arranged between the drilled screen and the non-functional layer.
[0007] As a preferred embodiment of the drilled screen smart wearable watch provided by the present invention, the thickness of the TP touch layer is 50 μm, 100 μm or 125 μm.
[0008] As a preferred embodiment of the drilled screen smart wearable watch provided by the present invention, the thickness of the non-functional layer is 50 μm, 100 μm or 125 μm.
[0009] As a preferred embodiment of the drilled screen smart wearable watch provided by the present invention, the thickness of the first optical adhesive layer is 50 μm.
[0010] As a preferred embodiment of the drilled screen smart wearable watch provided by the present invention, the thickness of the second optical adhesive layer is 125 μm or 150 μm.
[0011] As a preferred embodiment of the drilled screen smart wearable watch provided by the utility model, a frame-shaped glue overflow groove is etched on the lower surface of the watch cover located in the non-visible area, and a light-shielding ink is provided on the edge of the lower surface of the watch cover located in the non-visible area. The light-shielding ink is coated on the outer surface of the glue overflow groove and the lower surface of the watch cover.
[0012] As a preferred embodiment of the drilled screen smart wearable watch provided by the present invention, the cross-sectional shape of the glue overflow groove is V-shaped or semicircular.
[0013] As a preferred embodiment of the drilled screen smart wearable watch provided by the present invention, the thickness of the watch cover is 0.8 mm.
[0014] As a preferred embodiment of the drilled screen smart wearable watch provided by the present invention, the depth of the glue overflow groove is 0.05 mm.
[0015] As a preferred embodiment of the drilled screen smart wearable watch provided by the present invention, the lower surface of the watch cover is provided with OCA optical glue, and the OCA optical glue is arranged in the area formed by the overflow groove, and the thickness of the OCA optical glue is 0.1 mm.
[0016] The utility model has the following beneficial effects:
[0017] Since a non-functional layer is provided under the TP touch layer, and the TP touch layer and the non-functional layer are fixed by the first optical adhesive layer, the TP touch layer and the non-functional layer are pasted together before the large board is cut, so there is no problem of difficult film tearing. Only when the second optical adhesive layer is pasted between the drilled screen and the non-functional layer, the small board is pasted together. However, after the TP touch layer and the non-functional layer are pasted together, the overall thickness is increased, and the overall body is harder, and it is easier to tear the film without damaging the ITO. The added non-functional layer has no touch function and will not affect the touch effect. On the contrary, it can shield the interference of the lower drilled screen.

[0025] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first," "second," or "third" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.
[0026] The utility model provides a drilled screen smart wearable watch, which includes a watch cover, a pointer layer, a TP touch layer, a non-functional layer and a drilled screen, wherein the pointer layer is arranged below the watch cover; the TP touch layer is arranged below the pointer layer; the non-functional layer is arranged below the TP touch layer, and a first optical adhesive layer is arranged between the non-functional layer and the TP touch layer; the drilled screen is arranged below the non-functional layer, and a second optical adhesive layer is arranged between the drilled screen and the non-functional layer.
[0027] Since a non-functional layer is provided under the TP touch layer, and the TP touch layer and the non-functional layer are fixed by the first optical adhesive layer, the TP touch layer and the non-functional layer are pasted together before the large board is cut, so there is no problem of difficult film tearing. Only when the second optical adhesive layer is pasted between the drilled screen and the non-functional layer, the small board is pasted together. However, after the TP touch layer and the non-functional layer are pasted together, the overall thickness is increased, and the overall body is harder, and it is easier to tear the film without damaging the ITO. The added non-functional layer has no touch function and will not affect the touch effect. On the contrary, it can shield the interference of the lower drilled screen.
[0028] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be understood as limiting the present invention.
[0029] Example 1
[0030] See also Figure 1 and Figure 2, a drilled screen smart wearable watch provided by the utility model includes a watch cover 1, a pointer layer 2, a TP touch layer 3, a non-functional layer 4 and a drilled screen 5, the pointer layer 2 is arranged below the watch cover 1, the pointer layer 2 is an air layer, which is used to place the mechanical pointer; the TP touch layer 3 is arranged below the pointer layer 2; the non-functional layer 4 is arranged below the TP touch layer 3, and a first optical adhesive layer 6 is arranged between the non-functional layer 4 and the TP touch layer 3; the drilled screen 5 is arranged below the non-functional layer 4, and a second optical adhesive layer 7 is arranged between the drilled screen 5 and the non-functional layer 4. Since a non-functional layer 4 is provided under the TP touch layer 3, and the TP touch layer 3 and the non-functional layer 4 are adhered and fixed by the first optical adhesive layer 6, the TP touch layer 3 and the non-functional layer 4 are adhered before the large plate is cut, so there is no problem of difficult film tearing. Only when the second optical adhesive layer 7 is adhered between the drilled screen 5 and the non-functional layer 4, the adhesion is in the small plate state. However, after the TP touch layer 3 and the non-functional layer 4 are adhered, the overall thickness is increased, the whole is harder, and it is easier to tear the film without damaging the ITO. The added non-functional layer 4 has no touch function and will not affect the touch effect. On the contrary, it can shield the interference of part of the lower drilled screen 5.
[0031] The utility model is not only applicable to the drilled screen 5, but also applicable to other similar designs that need to be separated from the casing.
[0032] Furthermore, the thickness of the TP touch layer 3 is 50 μm, 100 μm or 125 μm.
[0033] Furthermore, the thickness of the non-functional layer 4 is 50 μm, 100 μm or 125 μm.
[0034] Furthermore, the thickness of the first optical adhesive layer 6 is 50 μm.
[0035] Furthermore, the thickness of the second optical adhesive layer 7 is 125 μm or 150 μm.
[0036] Furthermore, the second optical adhesive layer 7 is solid optical adhesive.
[0037] Example 2
[0038] As a further optimization of Example 1, in this embodiment, a frame-shaped overflow glue groove is etched on the lower surface of the watch cover 1 located in the non-visible area, and a light-shielding ink is provided on the edge of the lower surface of the watch cover 1 located in the non-visible area. The light-shielding ink is coated on the outer surface of the overflow glue groove and the lower surface of the watch cover 1. Since the overflow glue groove is provided on the lower surface of the watch cover 1, when applying the OCA optical glue, the OCA optical glue will overflow outward under pressure, and the excess glue will flow into and be stored in the overflow glue groove, preventing it from continuing to diffuse outward, thereby limiting the scope of the overflow glue, which can effectively prevent the overflow of the OCA optical glue and cause light leakage; the edge of the lower surface of the watch cover 1 is provided with light-shielding ink, and the light-shielding ink is coated on the outer surface of the overflow glue groove and the lower surface of the watch cover 1. The overflow glue groove is located in the light-shielding ink area on the edge of the watch cover 1, so it will not affect the appearance of the product.
[0039] Furthermore, OCA optical adhesive is applied to the lower surface of the watch cover 1. The OCA optical adhesive is placed within the area formed by the overflow groove. The shape of the overflow groove can be easily designed for etching, and the cross-section is not limited to semicircular or V-shaped. Currently, the industry's standard watch cover 1 thickness is approximately 0.8mm, and the OCA optical adhesive thickness is approximately 0.1mm. The overflow groove etching depth can be designed to be 0.05mm and adjusted based on the actual amount of overflow adhesive.
