Description

Technical Field

[0001] The utility model relates to a liquid crystal display device, more specifically, to a high-strength ultra-thin liquid crystal display module structure. Background Art

[0002] Current mobile phone LCD display modules, such as Figure 1 As shown in the figure, from top to bottom, it is mainly composed of cover plate S1, OCA layer S2, polarizer S3, LCD S4 and backlight S5. The cover plate is bonded to the liquid crystal display using OCA transparent optical adhesive through a full bonding process, which protects the LCD S4 and prevents it from being damaged when it is pressed or dropped. The overall thickness of the liquid crystal display module is about 2.0mm, while the total thickness of the cover plate S1 and OCA layer S2 commonly used in the industry is about 0.8mm, and the thickness of these two accounts for more than one-third of the total thickness of the module. With the trend of thinning mobile phones, how to reduce the thickness of display modules has become a problem of concern to everyone.

[0003] Chinese utility model patent document CN206505203U discloses 1. A backlight module, applied to a liquid crystal display screen, characterized in that the backlight module includes a glass light guide plate, a metal back plate and a fixing member for fixing the glass light guide plate and the metal back plate, the glass light guide plate is arranged on the metal back plate, the fixing member abuts against the glass light guide plate and the metal back plate, and under the abutting action of the fixing member, the glass light guide plate and the metal back plate are fixed together.

The backlight module also includes a side frame, which is fixed to the fixing member so that the metal back plate and the glass light guide plate are fixed to the side frame together. The backlight module also includes a connecting member, which fixes the metal back plate, the fixing member and the side frame together through fixing holes arranged on the metal back plate, the fixing member and the side frame. The fixing member is fixed to the metal back plate, the glass light guide plate and the side frame by adhesion. The fixing member is provided with a boss or a groove, and the side frame is correspondingly provided with a groove or a boss. The fixing member and the side frame are fixed by a concave-convex matching method.

[0004] Obviously, the patent fixes the glass light guide plate and the metal back plate together, and utilizes the strength of the glass light guide plate and the metal back plate to reduce the thickness of the glass light guide plate or the metal back plate accordingly while ensuring the same strength, thus meeting the user's requirements for ultra-thin characteristics and high strength of the LCD screen. However, the thinning effect of this thinning method is still poor.

[0029] 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.

[0030] As described in the background technology, the prior art for mobile phone LCD screens is that the mobile phone LCD screen is mainly composed of a cover plate, an OCA layer, a polarizer, an LCD and a backlight from top to bottom. The cover plate is bonded to the LCD display using OCA transparent optical adhesive through a full bonding process to protect the LCD from damage when it is pressed or dropped. The overall thickness of the LCD display module is about 2.0 mm, while the total thickness of the cover plate and OCA layer commonly used in the industry is about 0.8 mm, and the thickness of the two accounts for more than one-third of the total thickness of the module. With the trend of thinning mobile phones, how to reduce the thickness of the display module has become a problem of concern to everyone.

[0031] In order to solve this technical problem, the utility model provides a high-strength ultra-thin liquid crystal display module structure, comprising an LCD display screen 1, an upper polarizer 2 is provided on the upper surface of the LCD display screen 1, a lower polarizer 3 is provided on the lower surface of the LCD display screen 1, a backlight plate 4 is provided on the lower surface of the lower polarizer 3, and an anti-scratch film 5 is provided on the upper surface of the upper polarizer 2. The anti-scratch film 5 is attached to the upper surface of the upper polarizer 2. The thickness of the anti-scratch film 5 is between 80 microns and 120 microns. Preferably, the thickness of the anti-scratch film 5 is 100 microns.

[0032] Through the above structural design, since the anti-scratch film 5 replaces the traditional cover layer and OCA layer, the thickness is reduced by about 0.7 mm, which greatly reduces the overall thickness of the liquid crystal display module. In addition, since the OCA layer is eliminated, the amount of OCA used is also greatly reduced, reducing the production cost.

[0033] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0034] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0036] Example 1

[0037] like Figure 2 As shown, the high-strength ultra-thin liquid crystal display module structure includes an LCD display screen 1, an upper polarizer 2 is provided on the upper surface of the LCD display screen 1, a lower polarizer 3 is provided on the lower surface of the LCD display screen 1, a backlight plate 4 is provided on the lower surface of the lower polarizer 3, and an anti-scratch film 5 is provided on the upper surface of the upper polarizer 2.

[0038] It should be noted that the anti-scratch film 5 is attached to the upper surface of the upper polarizer 2 .

[0039] In addition, the anti-scratch film 5 has a thickness between 80 micrometers and 120 micrometers. Preferably, the anti-scratch film 5 has a thickness of 100 micrometers.

[0040] The working mode of this embodiment is described below.

[0041] Since the anti-scratch film 5 replaces the traditional cover layer and OCA layer, the thickness is reduced by about 0.7 mm, which greatly reduces the overall thickness of the liquid crystal display module.

[0042] In addition, since the OCA layer is eliminated, the usage of OCA is greatly reduced, and the production cost is reduced.

[0043] Example 2

[0044] like Figure 3 As shown, the high-strength ultra-thin liquid crystal display module structure provided in Example 1 is further optimized. Specifically, a release film 6 is provided on the upper surface of the anti-scratch film 5 .

[0045] A tear handle 61 is provided at the edge of the release film 6 .

[0046] The working mode of this embodiment is described below.

[0047] The release film 6 can effectively protect the surface of the anti-scratch film 5 and prevent it from being contaminated by particles during the film application process. The tearing handle 61 can facilitate workers to perform film tearing operations.

[0048] Example 3

[0049] like Figure 4 As shown, the high-strength ultra-thin liquid crystal display module structure provided in Example 1 or 2 is further optimized. Specifically, the LCD display screen 1 includes an upper glass substrate 11, a CF film 12 is provided on the lower surface of the upper glass substrate 11, a TFT layer 13 is provided at the lower part of the CF film 12, a lower glass substrate 14 is provided on the lower surface of the TFT layer 13, and the CF film 12 and the TFT layer 13 are bonded and connected by a frame glue 15.

[0050] It should be noted that the upper glass substrate 11 is nano-ceramic glass. The lower glass substrate 14 is nano-ceramic glass.

[0051] In addition, the extended area of ​​the lower glass substrate 14 is larger than that of the upper glass substrate 11 .

[0052] The working mode of this embodiment is described below.

[0053] Since the upper glass substrate 11 and the lower glass substrate 14 are both nano-crystal glass, nano-crystal glass is formed by nucleating and crystallizing conventional lithium aluminum silicon glass at a certain temperature to form a polycrystalline solid material with a microcrystalline phase and a glass phase, and has the excellent properties of both glass and ceramics, and its drop resistance is more than twice that of conventional cover glass. When cracks appear in the glass, the crystal phase in the nano-crystal glass can prevent the cracks from expanding. The strength of the LCD display screen 1 itself can be effectively improved without the need to add a thicker cover plate for protection in the original design.

[0054] Among them, OCA is optical adhesive.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] Obviously, the embodiments described above are only some embodiments of the present application, rather than all embodiments.

The present application can be implemented in many different forms.
