[0025] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0026] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0027] In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0028] The utility model provides a liquid crystal display screen capable of enhancing the anti-drop level of a module, comprising a lower polarizer, a lower glass, an upper glass, an upper polarizer and a cover plate which are sequentially stacked from bottom to top, wherein the lower glass is longer than the upper glass and extends outward to form a step, an FPC is bound to the upper surface of the lower glass located at the step, the cover plate is fixed to the upper polarizer by OCA glue, and the outer dimensions of the OCA glue are consistent with the outer dimensions of the lower glass.
[0029] Since the outer dimensions of the OCA glue are consistent with those of the lower glass, the size of the OCA glue is increased compared to traditional LCD screens. When the OCA glue is attached, the OCA glue will fill the gap between the lower glass and the cover plate of the LCD screen, thereby playing a supporting and buffering role, enhancing the ability to resist falling and extrusion, and improving the competitiveness of the product.
[0030] 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 is described in detail below in conjunction with the accompanying drawings and embodiments, and 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 construed as limitations on the present invention.
[0031] See also Figure 1 , a liquid crystal display screen capable of enhancing the anti-drop level of the module provided by the utility model, comprising a lower polarizer 1, a lower glass 2, an upper glass 3, an upper polarizer 4 and a cover plate 5 which are sequentially stacked from bottom to top, the lower glass 2 being longer than the upper glass 3 and extending outward to form a step, an FPC 6 being bound to the upper surface of the lower glass 2 located at the step, the cover plate 5 and the upper polarizer 4 being fixed by OCA glue 7, the outer dimensions of the OCA glue 7 being consistent with the outer dimensions of the lower glass 2. Since the outer dimensions of the OCA glue 7 are consistent with the outer dimensions of the lower glass 2, the size of the OCA glue 7 is larger than that of the traditional liquid crystal display screen, and when the OCA glue 7 is attached, the OCA glue 7 will fill the gap between the lower glass 2 and the cover plate 5 of the liquid crystal display screen, thereby playing a supporting and buffering role, enhancing the ability to resist falling and extrusion, and improving the competitiveness of the product.
[0032] Furthermore, the OCA glue 7 is liquid glue, so that the OCA glue 7 can flow better into the gap between the lower glass 2 and the cover plate 5, thereby playing a supporting and buffering role.
[0033] Furthermore, when applying the OCA glue 7, more OCA glue is applied to the edge area of the lower glass 2 so that the OCA glue 7 can directly extend to the upper surface of the lower glass 2 during bonding to play a supporting and buffering role.
[0034] Furthermore, the OCA glue 7 covers the upper surface of the lower glass 2 and the edge of the upper surface of the FPC 6, so that the lower glass 2, FPC 6, OCA glue 7 and the cover plate 5 are integrated, thereby improving the ability to resist falling and squeezing, and improving the competitiveness of the product.
[0035] See also Figure 2 and Figure 3 As a further optimization scheme of Example 1, in this embodiment, before the cover plate 5 and the OCA glue 7 are attached, an insulating shielding integrated layer 8 is attached to the FPC6, and the insulating shielding integrated layer 8 includes insulating paper 81 and conductive shielding material 82. The conductive shielding material 82 is arranged above the insulating paper 81. The area of the insulating paper 81 is smaller than the area of the conductive shielding material 82. The insulating paper 81 can completely cover the FPC6. The conductive shielding material 82 has a through hole 83 at the edge of the insulating paper 81, and the through hole 83 is located in the area where no components are provided. Since the conductive shielding material 82 has a through hole 83 at the edge of the insulating paper 81, the operator can see the edge of the insulating paper 81, so that the operator can judge the position of the insulating paper 81 when attaching, so as to avoid being attached to the FPC6 in an offset manner or not being attached, thereby preventing a short circuit and avoiding economic losses.
[0036] Furthermore, the through hole 83 is a circular hole, and one end of the opening waste is connected to the conductive shielding material 82. So that the position of the insulating paper 81 can still be observed by breaking the opening waste at the circular hole, and the opening waste is covered back after being pasted, so as to avoid the opening being unable to ensure conductive shielding.
[0037] Furthermore, a double-sided tape is provided at the bottom of the waste material with holes, and the waste material with holes is pasted back by the double-sided tape to avoid failure to ensure conductive shielding at the holes.
[0038] Furthermore, one side of the insulating paper 81 extends beyond the conductive shielding material 82, so that the operator can determine the specific position of the insulating paper 81 through the insulating paper 81 extending beyond the conductive shielding material 82, thereby avoiding biased or no attachment to the FPC6, thereby preventing a short circuit and economic losses.
[0039] Furthermore, the conductive shielding material 82 is conductive paper or copper foil, which can form a conductive shielding effect.
[0040] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0041] Obviously, the embodiments described above are only some embodiments of the present application, rather than all embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application. The present application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.
