Description

Technical Field

[0001] The utility model relates to the field of liquid crystal display, in particular to a cover frame sticker LCM which can prevent foreign matter from entering the surface of LCD. Background Art

[0002] LCM refers to liquid crystal display module, which is the most important component of liquid crystal display. LCM is composed of LCD, backlight and cover plate. LCD is composed of FPC (flexible circuit board), upper polarizer, upper glass, lower glass and lower polarizer. LCD is placed on the backlight, and there are plastic frame arms around the backlight to wrap the LCD.

[0003] For example, the patent document with application number CN200510100552.0 discloses a liquid crystal display module, which adopts the above-mentioned packaging method, which is also the most commonly used method at present.

[0004] However, the technical solution disclosed in the above patent document still has limitations in specific use, because at the LCD filling and sealing position, the backlight glue frame is usually opened to avoid air, so as to avoid squeezing the seal and causing damage to the LCD due to leakage. The cover plate is attached to the arm around the backlight through a double-sided adhesive frame. Since the cover plate is framed on the arm around the backlight glue frame, in order to ensure the tightness of the two, the height of the LCD will be lower than the arm around the backlight, which leads to a gap between the LCD and the cover plate. Dust and foreign matter can easily pass through the window of the LCD filling and sealing of the backlight glue frame, and enter the LCD surface through this gap, affecting the LCM display effect. Utility Model Content

[0034] 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.

[0035] As described in the background technology, at the LCD filling and sealing position, a window is usually opened on the backlight glue frame to avoid air, so as to avoid squeezing the seal and causing damage to the LCD due to leakage. The cover plate is attached to the arm around the backlight through a double-sided adhesive frame. Since the cover plate is framed and attached to the arm around the backlight glue frame, in order to ensure the tightness of the two, the height of the LCD will be lower than the arm around the backlight, which leads to a gap between the LCD and the cover plate. Dust and foreign matter can easily pass through the window of the backlight glue frame at the LCD filling and sealing position, and enter the LCD surface through this gap, affecting the LCM display effect.

[0036] In order to solve this technical problem, the utility model provides a cover frame sticker LCM which can prevent foreign matter from entering the LCD surface.

[0037] Specifically, please refer to Figure 1-Figure 9 , to prevent foreign matter from entering the LCD surface cover frame LCM, including:

[0038] Display subject 1;

[0039] The backlight glue frame 2 has a receiving groove 3 on its surface which can receive the display body 1, and a glue seal 4 is provided on the side wall of the receiving groove 3, and the glue seal 4 can guide liquid into the receiving groove 3;

[0040] The cover plate 5 can be connected to the surface of the backlight glue frame 2 where the receiving groove 3 is provided to close the receiving groove 3;

[0041] The sealing structure is arranged in the glue seal 4 to seal the glue seal 4 .

[0042] The utility model can seal the receiving groove 3 through the sealing structure to prevent dust and foreign matter from entering and adhering to the LCD surface through the LCD filling and sealing window position to affect the display effect. Specifically, the display body 1, the backlight glue frame 2 and the cover plate 5 are directly guided to be connected in a sequential order (first guiding the display body 1 and the backlight glue frame 2 to be connected, and then filling the liquid to the set position. The method of filling the liquid here is the existing technology and will not be described in detail here, and finally the cover plate 5 is closed). When the cover plate 5 is connected to the surface of the backlight glue frame 2 where the receiving groove 3 is set, the sealing structure will block the glue seal 4, so that the receiving groove 3 forms a closed space to prevent dust and foreign matter from entering and adhering to the LCD surface through the LCD filling and sealing window position.

[0043] The window position of the utility model can refer to Figure 1-2 As shown, it shows that there is a window in the receiving groove 3.

[0044] The LCD filling and sealing port refers to the location of the filling and sealing port section 8 in the present invention.

[0053] The sealing structure is arranged in the glue seal 4 to seal the glue seal 4 .

[0054] The utility model can seal the receiving groove 3 through the sealing structure to prevent dust and foreign matter from entering and adhering to the LCD surface through the LCD filling and sealing window position to affect the display effect. Specifically, the display body 1, the backlight glue frame 2 and the cover plate 5 are directly guided to be connected in a sequential order (first guiding the display body 1 and the backlight glue frame 2 to be connected, and then filling the liquid to the set position. The method of filling the liquid here is the existing technology and will not be described in detail here, and finally the cover plate 5 is closed). When the cover plate 5 is connected to the surface of the backlight glue frame 2 where the receiving groove 3 is set, the sealing structure will block the glue seal 4, so that the receiving groove 3 forms a closed space to prevent dust and foreign matter from entering and adhering to the LCD surface through the LCD filling and sealing window position.

Specifically, the display body 1, the backlight glue frame 2 and the cover plate 5 are directly guided to be connected in a sequential order (first guiding the display body 1 and the backlight glue frame 2 to be connected, and then filling the liquid to the set position. The method of filling the liquid here is the existing technology and will not be described in detail here, and finally the cover plate 5 is closed). When the cover plate 5 is connected to the surface of the backlight glue frame 2 where the receiving groove 3 is set, the sealing structure will block the glue seal 4, so that the receiving groove 3 forms a closed space to prevent dust and foreign matter from entering and adhering to the LCD surface through the LCD filling and sealing window position. In this process, the thickness of the display body 1 is controlled not to be greater than the depth of the receiving groove 3 (that is, slightly less than or equal to the depth of the receiving groove 3. If it is too small, it is easy to cause a gap between the LCD (that is, the display body 1) and the cover plate 5, and dust and foreign matter can easily pass through the backlight glue frame 2 at the LCD filling seal window and enter the LCD surface through this gap, affecting the LCM display effect.

[0071] In some specific embodiments, the cover plate 5 and the backlight adhesive frame 2 are bonded together by double-sided adhesive tape, and this arrangement is for realizing a quick connection between the cover plate 5 and the backlight adhesive frame 2 .

[0072] In some specific embodiments, the sealing structure includes a sealing sheet 10 disposed in the glue seal 4, and the thickness of the sealing sheet 10 is less than the width of the glue seal 4. This arrangement is to ensure that the cooperation between the potting port section 8 and the glue seal 4 is not affected, and the sealing sheet 10 can also fully block external dust.

[0073] In some specific embodiments, the sealing sheet 10 and the backlight adhesive frame 2 are integrally formed to prevent dust from entering through the gap between the sealing sheet 10 and the backlight adhesive frame 2 .

[0074] In some specific embodiments, a display area 12 is provided at a position corresponding to the surface of the cover plate 5 and the receiving groove 3 , and the length and width of the display area 12 are smaller than those of the receiving groove 3 .
