[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 with an ITO heating plate, which comprises a heating glass plate, a lower polarizer, a lower substrate, an upper substrate and an upper polarizer which are sequentially stacked from bottom to top, a bonding frame glue is arranged between the lower polarizer and the heating glass plate, an ITO heating pattern is arranged on the upper surface of the heating glass plate, FPCs are respectively bound to the two ends of the upper surface of the heating glass plate, both of the two FPCs are electrically connected to the ITO heating pattern, and an adhesive is arranged at the gap between the heating glass plate and the lower substrate on the outside of the bonding frame glue, and the adhesive covers the FPC.

[0029] Because a heating glass plate is arranged below the lower polarizer, the upper surface of the heating glass plate is a layer of transparent ITO heating pattern, and two FPCs are bound on the left and right sides. When the heating glass plate is powered on, the heating glass plate will heat up immediately, and by transferring heat to the display module, low-temperature heating is achieved to improve the display effect, so that the LCD screen can automatically increase the temperature when working in a low-temperature environment, so that the voltage provided by the driver IC can always reach the working voltage of the liquid crystal, avoiding the phenomenon of the LCD screen display becoming faint or even not displaying, ensuring that the LCD screen can display normally and improving the competitiveness of the product. The FPCs bound at both ends of the heating glass plate are placed in the gap between the heating glass plate and the lower glass of the display screen, and the gap is injected with adhesive to solidify, so as to enhance the pull-out force of the heating glass plate after the FPC is bound, and at the same time enhance the compressive strength of the edge of the display module.

[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] Example 1

[0032] See also Figure 1 and Figure 2, a liquid crystal display screen with an ITO heating plate provided by the utility model, comprising a heating glass plate 1, a lower polarizer 2, a lower substrate 3, an upper substrate 4 and an upper polarizer 5 which are stacked in sequence from bottom to top, a bonding frame glue 6 is arranged between the lower polarizer 2 and the heating glass plate 1, an ITO heating pattern is arranged on the upper surface of the heating glass plate 1, FPCs 7 are respectively bound to the two ends of the upper surface of the heating glass plate 1, and the two FPCs 7 are electrically connected to the ITO heating pattern, and an adhesive 8 is arranged at the gap between the heating glass plate 1 and the lower substrate 3 outside the bonding frame glue 6, and the adhesive 8 covers the FPC 7. Since a heating glass plate 1 is arranged below the lower polarizer 2, the upper surface of the heating glass plate 1 is a layer of transparent ITO heating pattern, and two FPC7 are bound on the left and right sides, when the heating glass plate 1 is powered on, the heating glass plate 1 will heat up immediately, and by transferring heat to the display module, low-temperature heating is achieved to improve the display effect, so that the liquid crystal display screen can autonomously increase the temperature when working in a low-temperature environment, so that the voltage provided by the driver IC31 can always reach the working voltage of the liquid crystal, avoiding the phenomenon of the liquid crystal display screen becoming dim or even not displaying, ensuring that the liquid crystal display screen can display normally, and improving the competitiveness of the product. The FPC7 bound at both ends of the heating glass plate 1 is placed in the gap between the heating glass plate 1 and the lower substrate 3 of the display screen, and the adhesive 8 is injected into the gap for curing to enhance the pull-out force of the heating glass plate 1 after the FPC7 is bound, and at the same time enhance the compressive strength of the edge of the display module.

[0033] Furthermore, the heated glass plate 1 is transparent in color to avoid affecting the transparent display.

[0034] Furthermore, the adhesive 8 is UV adhesive.

[0035] Furthermore, one of the two FPCs 7 is a positive electrode FPC 7 , and the other is a negative electrode FPC 7 .

[0036] Furthermore, the ITO heating pattern includes an internal pattern and an external pattern, the internal pattern is located inside the upper substrate 4, and the external pattern is located outside the internal pattern. Since there is a certain temperature difference between the inside and outside of the liquid crystal display screen, the internal pattern and the external pattern can be controlled separately to heat the liquid crystal display screen separately so that the internal and external temperatures remain consistent.

[0037] Example 2

[0038] See also Figure 3 and Figure 4As a further optimization scheme of Example 1, in this embodiment, a component 31 is arranged above the lower substrate 3, and an insulating shielding integrated layer 9 is attached to the component 31. The insulating shielding integrated layer 9 includes insulating paper 91 and conductive shielding material 92. The conductive shielding material 92 is arranged above the insulating paper 91. The area of ​​the insulating paper 91 is smaller than the area of ​​the conductive shielding material 92. The insulating paper 91 can completely cover the component 31. The conductive shielding material 92 has a through hole 93 at the edge of the insulating paper 91, and the through hole 93 is located in the area where no component is provided. Since the conductive shielding material 92 has a through hole 93 at the edge of the insulating paper 91, the operator can see the edge of the insulating paper 91, so that the operator can judge the position of the insulating paper 91 when attaching, so as to avoid being attached to the component 31 in an offset manner or not being attached, thereby preventing a short circuit and avoiding economic losses.

[0039] Furthermore, the component 31 is a driver IC and a flexible circuit board.

[0040] Furthermore, the through hole 93 is a circular hole, and one end of the opening waste is connected to the conductive shielding material 92. So that the position of the insulating paper 91 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.

[0041] 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.

[0042] Furthermore, one side of the insulating paper 91 extends beyond the conductive shielding material 92, so that the operator can determine the specific position of the insulating paper 91 through the insulating paper 91 extending beyond the conductive shielding material 92, thereby avoiding biased or non-attachment to the component 31, thereby preventing a short circuit and economic losses.

[0043] Furthermore, the conductive shielding material 92 is conductive paper or copper foil, which can form a conductive shielding effect.

[0044] 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.

[0045] 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.
