[0027] 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 indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0028] This invention provides a curved solar touch screen with reduced manufacturing difficulty, comprising curved tempered glass and ultra-thin flexible glass disposed below the curved tempered glass. The lower surface of the curved tempered glass, located in the non-visible area, is provided with a light-shielding ink layer. The upper surface of the ultra-thin flexible glass is provided with a solar energy functional layer. The lower surface of the ultra-thin flexible glass is provided with a touch function layer. The curved tempered glass and the ultra-thin flexible glass are fully bonded together by OCA optical adhesive.
[0029] Since the solar energy functional layer and the touch control functional layer can be fabricated on ultra-thin flexible glass first, the flexibility of ultra-thin flexible glass allows the solar energy functional layer and the touch control functional layer to be fabricated in a flat state. Then, the ultra-thin flexible glass with the solar energy functional layer and the touch control functional layer is bonded to the curved tempered glass using OCA optical adhesive. This reduces the difficulty of fabricating the solar energy functional layer and the curved touch control functional layer, reduces the requirements for processes and technologies, improves product yield, and thus reduces product costs and enhances product competitiveness.
[0030] 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 with reference to the accompanying drawings. The present invention will be described in detail below with reference to the accompanying drawings and embodiments, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0031] Example 1, please refer to Figure 1 and Figure 2This invention provides a curved solar touchscreen with reduced manufacturing difficulty, comprising curved tempered glass 1 and ultra-thin flexible glass 2 disposed below the curved tempered glass 1. A light-shielding ink layer 3 is disposed on the lower surface of the curved tempered glass 1 in the non-visible area. A solar function layer 4 is disposed on the upper surface of the ultra-thin flexible glass 2, and a touch function layer 5 is disposed on the lower surface of the ultra-thin flexible glass 2. The curved tempered glass 1 and the ultra-thin flexible glass 2 are fully bonded together using OCA optical adhesive 6. Since the solar function layer 4 and the touch function layer 5 can be fabricated on the ultra-thin flexible glass 2 first, utilizing the flexibility of the ultra-thin flexible glass 2, the solar function layer 4 and the touch function layer 5 can be fabricated in a planar state. Then, the ultra-thin flexible glass 2 with the solar function layer 4 and the touch function layer 5 is bonded to the curved tempered glass 1 using OCA optical adhesive 6. This reduces the manufacturing difficulty of the solar function layer 4 and the curved touch function layer 5, lowers the requirements for processes and technologies, improves product yield, and thus reduces product costs and enhances product competitiveness.
[0032] Furthermore, the trace material of the touch function layer 5 at the edge of the ITO in the viewing area is molybdenum-aluminum-molybdenum, graphene, or nano-silver.
[0033] Furthermore, it also includes FPC7, a portion of which is bonded to the upper surface of the ultra-thin flexible glass 2 located in the solar energy functional layer 4, and another portion of which is bonded to the lower surface of the ultra-thin flexible glass 2 located in the touch functional layer 5. The functions of the touch functional layer 5 and the solar energy functional layer 4 can be realized by using one FPC7, eliminating the need for two FPC7s and reducing product costs.
[0034] Furthermore, both the curved tempered glass 1 and the ultra-thin flexible glass 2 are colorless and transparent glass, and the color of the light-shielding ink layer 3 is black.
[0035] Example 2, please refer to Figures 3 to 5 As a further optimization of Embodiment 1, in this embodiment, the FPC7 has a gold finger 71 at its end, and a protective film 72 is attached to the surface of the FPC7 at the gold finger 71, with the edge of the protective film 72 extending beyond the edge of the gold finger 71. Because the protective film 72 is attached to the surface of the FPC7 at the gold finger 71, and the edge of the protective film 72 extends beyond the edge of the gold finger 71, the protective film 72 ensures that the FPC7 will not directly contact the gold finger 71 during various process operations and packaging and transportation. This solves the problem of external factors damaging the FPC7 fingers and avoids quality problems such as deformation, twisting, and damage to the FPC7 during module bonding and assembly operations and transportation.
[0036] Furthermore, the protective film 72 is a PET film, which has a lower cost, better protective effect, and higher cost performance.
[0037] Furthermore, the edge of the protective film 72 extends at least 1 mm beyond the edge of the gold finger 71 to ensure that when touched, only the edge of the protective film 72 is touched and the gold finger 71 is not touched, thereby protecting the gold finger 71 from damage.
[0038] Furthermore, an adhesive 73 is provided on the lower surface of the protective film 72, avoiding the gold fingers 71, and the protective film 72 is adhered and fixed to the FPC 7 by the adhesive 73. Preferably, the adhesive 73 is glue or double-sided adhesive. In this embodiment, the adhesive 73 is double-sided adhesive. More preferably, the glue or double-sided adhesive has a weak tack to facilitate the subsequent removal of the protective film 72.
[0039] Furthermore, the protective film 72 is provided with a tear-off handle 74, which allows the protective film 72 to be quickly removed.
[0040] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0041] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application.
