Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "left", "right", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
Referring to fig. 1, an integrated liquid crystal display module according to an exemplary embodiment of the present disclosure includes, in order from top to bottom, a polarizing layer 3, a cover glass 1, a color film substrate 4, a black matrix 5 formed on a lower surface of the color film substrate 1, a liquid crystal layer 6, and a TFT array substrate 7, where the cover glass 1 and the color film substrate 4 are integrally formed, and a driving circuit 8 is disposed on a surface of the TFT array substrate 7 facing the cover glass.
In the related art, the thickness of the photoresist used for adhering the liquid crystal module is 150-200 μm, and the light transmittance of the liquid crystal module with the color film substrate 4 and the cover glass 1 adhered by the photoresist is reduced by about 2%. According to the integrated liquid crystal display module provided by the embodiment, the cover plate glass 1 and the color film substrate 4 are made of the same glass, photoresist in related technologies is removed, the overall thickness of the liquid crystal display panel is thinned by 150-200 μm, and the light transmittance is improved by about 2%, so that the integrated liquid crystal display panel provided by the disclosure is smaller in overall thickness and higher in light transmittance.
The cover plate glass 1 and the color film substrate 4 are not required to be attached through photoresist, and the labor cost and the reject ratio of liquid crystal module products are reduced.
In addition, the thicknesses of the cover glass 1 and the color film substrate 4 are not reduced, and only two modules, namely the cover glass 1 and the color film substrate 4, are manufactured on the same glass, so that the strength of the liquid crystal module structure is ensured.
Referring to fig. 3, the color filter substrate 4 of the related art is a flat monolithic glass substrate. Referring to fig. 4, a plurality of color film substrates 4 are provided in the present embodiment and are uniformly arranged at the bottom of the cover glass 1.
The black matrix 5 is formed at the bottom of each color film substrate 4, and in the related art, the black matrix is formed below a whole glass substrate, and the color film substrates 4 arranged at intervals in the embodiment can reduce the area for forming the black matrix 5, so that the material and time for manufacturing the process are saved.
The groove position between every two color film substrates 4 is the cover glass 1, and when the spacer 10 and the black matrix 5 are manufactured, only the lower surface of the color film substrate 4 is needed.
The spacer 10 is located between the color film substrate 4 and the TFT array substrate 7, and is used for supporting the color film substrate 4 and the TFT array substrate 7, so that a certain space is maintained between the color film substrate 4 and the TFT array substrate 7, and when the driving circuit 8 is placed on the side of the TFT array substrate 7 facing the cover glass, the height of the driving circuit 8 does not exceed the height between the TFT array substrate 7 and the cover glass 1. The spacer may be selected from a polymer resin material.
Unlike the related art in which the polarizing layer is attached to the color film substrate 4, the polarizing layer 3 of the present embodiment is directly attached to the upper surface of the glass cover plate 1. The polarizing layer 3 of this embodiment is the film that has polarization, is equivalent to the polaroid among the correlation technique, and the thickness of film is less than the thickness of polaroid far away, has further reduced liquid crystal module's whole thickness.
Referring to fig. 2 and 5, the polarizing layer 3 has the same size as the cover glass 1, and the polarizing layer 3 includes a polarizing area 31 and a non-polarizing area 32.
The polarizing region 31 is a film having a polarizing effect, the size of the polarizing region 31 is the same as that of the liquid crystal layer 6, and the polarizing region 31 is located directly above the liquid crystal layer 6, that is, the entire liquid crystal layer 6 can be covered by the polarizing region 31, thereby forming a liquid crystal display region.
The non-polarized region 32 is a transparent and non-polarizing film, which is a portion of the polarizing layer 3 beyond the liquid crystal layer (i.e., the display region), and the non-polarized region 32 serves only as a protective film for the glass cover 1 and does not have a polarizing function.
In order to prevent the liquid crystal molecules of the liquid crystal layer 6 from leaking, a sealant frame 9 is formed in the peripheral area of the color filter substrate 4 and the TFT array substrate 7.
In this embodiment, the driving circuit 8 is soldered on the TFT array substrate 7. The welding connection mode is stable and firm, so that the connection between the driving circuit 8 and the TFT array substrate 7 is stable, and the signal transmission stability of the liquid crystal display module is improved.
Of course, the driving circuit 8 may be fixed on the TFT array substrate by other fixing methods, such as fixing the driving circuit 8 on the TFT array substrate 7 by a fastener.
Because the size of the cover plate glass 1 is far larger than that of the TFT array substrate 7, the box combination mode of the liquid crystal module can only be changed from large plate box combination to single plate box combination. Similarly, since the size of the cover glass 1 is much larger than that of the TFT array substrate 7, the process of fixing the driving circuit 8 is completed before the cassette is mounted, and the cover glass 1 needs to be cut to prevent the height of the driving circuit 8 from exceeding the cover glass 1, which results in waste of materials.
An exemplary embodiment of the present disclosure further provides a mobile phone, which includes the above-mentioned integrated liquid crystal display module. Because the cover plate glass 1 and the color film substrate 4 in the mobile phone are integrally formed on the same glass substrate, photoresist in the related technology is removed, so that the whole thickness of the liquid crystal display panel is reduced, the light transmittance is improved, the thickness of the mobile phone is reduced, the display effect is better, and a good experience effect is brought to a mobile phone user.
The above description is only exemplary of the present disclosure and should not be taken as limiting the disclosure, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present disclosure should be included in the scope of the present disclosure.
