Description

Technical Field

[0001] The utility model relates to the technical field of display modules, in particular to a full-fitting module. Background Art

[0002] The current fully laminated module usually consists of a touch screen and a liquid crystal display panel. First, a circle of dam glue is applied to the periphery of the liquid crystal display panel, and then liquid bonding glue is applied inside the circle of dam glue after the dam glue is pre-cured. Then the touch screen is laminated to the liquid crystal display panel, and then the dam glue and liquid bonding glue are cured, and finally the backlight module is assembled.

[0003] However, the thickness of the dam glue applied in the above manner is affected by factors such as the size of the glue coating needle and the needle travel speed, resulting in uneven thickness of the dam glue, which in turn leads to uneven thickness of the applied liquid bonding glue, thereby affecting the flatness of the touch screen and the LCD panel, and easily generating bubbles between the touch screen and the LCD panel.

These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0023] 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, or a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; 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. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0024] In the related art, a fully laminated module is usually composed of a touch screen and a liquid crystal display panel. First, a circle of dam glue is applied on the periphery of the liquid crystal display panel, and after the dam glue is pre-cured, liquid bonding glue is applied inside the circle of dam glue. Then the touch screen is laminated to the liquid crystal display panel, and then the dam glue and liquid bonding glue are cured, and finally the backlight module is assembled. However, the coating thickness of the dam glue in the above-mentioned manner is affected by factors such as the size of the glue coating needle and the needle routing speed, resulting in uneven thickness of the dam glue, which in turn results in uneven thickness of the coated liquid bonding glue, thereby affecting the flatness of the touch screen and the liquid crystal display panel, and bubbles are easily generated between the touch screen and the liquid crystal display panel.

[0025] In view of the above problems, the embodiments of the present application provide a full-lamination module, which can improve the lamination flatness between the touch screen and the liquid crystal display panel and avoid the generation of bubbles between the touch screen and the liquid crystal display panel.

[0026] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0027] See also Figure 1 and Figure 2 A fully laminating module includes: a touch screen 100, an adhesive component 200, a liquid laminating adhesive 300 and a liquid crystal display panel 400. The adhesive component 200 includes a foam 210, a sticky part and a non-sticky part. The sticky part is arranged on one side of the foam 210, and the non-sticky part is arranged on the other side of the foam 210. The sticky part adheres to the touch screen 100, and the foam 210 and the middle area of ​​the touch screen 100 form a coating area; the liquid laminating adhesive 300 is arranged in the coating area; the liquid crystal display panel 400 is arranged on the liquid laminating adhesive 300.

[0028] It should be noted that the foam 210 has a rectangular cross-sectional structure and is in the shape of a rectangle with a hollow middle. The sticky portion is a sticky portion of the foam 210, which is used to bond to the touch screen 100, and the non-sticky portion is a non-sticky portion of the foam 210, and the sticky portion and the non-sticky portion are parallel to each other. Further, the middle area of ​​the touch screen 100 and the foam 210 are enclosed into a coating area, and the coating area is used to apply the liquid bonding glue 300. After applying the liquid bonding glue 300, the liquid crystal display panel is bonded to the touch screen 100, and then the liquid bonding glue 300 is cured. Finally, the backlight module is assembled. Different from the traditional method, the present application is to adhere the single-sided sticky foam 210 to the touch screen 100, and then the liquid bonding glue 300 is applied to the middle area of ​​the touch screen 100. Finally, the liquid crystal display panel 400 is bonded to the touch screen 100. The above method saves the pre-curing process of the dam glue in the traditional method. At the same time, the thickness and flatness of the foam 210 can be kept consistent, so that the liquid bonding glue 300 can be spread more evenly in the coating area, thereby making the flatness of the LCD display panel 400 higher, and no bubbles will be generated between the touch screen 100 and the LCD display panel 400.

[0029] See also Figure 1 In one embodiment, a fully laminated module further includes a first FPC board 500, and the first FPC board 500 is disposed on the liquid crystal display panel 400. Specifically, a first component area 510 is opened on the first FPC board 500.

[0033] In one embodiment, the thickness of the liquid bonding adhesive 300 is in the range of 0.50 mm to 0.52 mm.

[0034] It should be noted that the thickness of the liquid bonding adhesive 300 of the present application is 0.50 mm, and the liquid bonding adhesive 300 of this thickness has better adhesion.

[0035] See also Figure 1In one embodiment, the touch screen 100 is parallel to the liquid crystal display panel 400. It should be noted that the liquid crystal display panel 400 covers the touch screen 100 and is parallel to the touch screen 100 to ensure the display effect.

[0036] See also Figure 1 In one implementation, an ink area 120 is provided on the touch screen 100 .

[0037] It should be noted that the ink area 120 is opposite to the foam 210 , that is, the ink area 120 is located on the other side of the touch screen 100 .
