Detailed Description

The present invention provides a liquid crystal display module and a liquid crystal display device, and the present invention is further described in detail below to make the purpose, technical scheme and effect of the present invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

A liquid crystal display module, as shown in FIG. 1 ~ 3, comprises a first glass substrate 10, a color filter 20, a first liquid crystal layer 30, a second glass substrate 40, a second liquid crystal layer 50, a third glass substrate 60, a first polarization functional layer 70 disposed above the first liquid crystal layer 30, a second polarization functional layer 80 disposed between the first liquid crystal layer 30 and the second liquid crystal layer 50, and a third polarization functional layer 90 disposed below the second liquid crystal layer 50, wherein the first liquid crystal layer 30 and the second liquid crystal layer 50 are connected to the same signal source, the first polarization functional layer 70 is disposed above the first liquid crystal layer 30, the first polarization functional layer is disposed above or on the first liquid crystal layer 30, and the second polarization functional layer is disposed above or below the first liquid crystal layer 30, and the first polarization functional layer is not limited, such as the upper side or the lower side of the first glass substrate 10, the second polarization functional layer 80 is disposed between the first liquid crystal layer 30 and the second liquid crystal layer 50, the first liquid crystal layer 30 is not limited, such as the upper side or the lower side of the second glass substrate 40, and the third polarization functional layer 60 is disposed below the third liquid crystal layer 50, and the third liquid crystal layer is not limited.

Since the first liquid crystal layer 30 and the second liquid crystal layer 50 are connected to the same signal source, i.e., driven by the same signal chip, different gray scales are synchronously displayed according to different input signals, so that accurate and synchronous control of the luminous flux emitted after the backlight enters the second liquid crystal layer 50 can be realized. Preferably, the sub-pixels of the first liquid crystal layer 30 and the sub-pixels of the second liquid crystal layer 50 are controlled to correspond to each other one by one, and if the sub-pixels adjacent to the fully bright sub-pixels of the first liquid crystal layer 30 are in an off state, the sub-pixels of the second liquid crystal layer 50 corresponding to the sub-pixels in the off state of the first liquid crystal layer 30 are also in an off state, so that only a very small part of light enters the first liquid crystal layer 30, and the backlight enters the first liquid crystal layer 30 and then must pass through low-transmittance layers such as a polarization function layer and a color filter layer to finally exit, so that almost no light leaks from the off sub-pixel region. Therefore, the structure can realize the effects of reducing dark state light leakage, improving contrast, and improving color purity and color gamut coverage; meanwhile, the structure is greatly simplified because one piece of glass and one or more pieces of polarizing plates are removed by the prior technical scheme, and the reliability of the whole liquid crystal module is greatly improved after the polarizing plates are removed because the polarizing plates are made of low-reliability materials.

In the liquid crystal display module, the first glass substrate 10, the second glass substrate 40 and the first glass substrate 60 are bonded by the frame adhesive 100, the first glass substrate 10, the second glass substrate 40 and the third glass substrate 60 are bonded into a whole by the frame adhesive 100, so that a main body frame of the liquid crystal display module is formed, and then other parts are filled or coated on the main body frame.

Preferably, in the liquid crystal display module, the first glass substrate 10 and the second glass substrate 40 are TFT array glass substrates, and the matrix arrays of the first glass substrate 10 and the second glass substrate 40 are the same, so as to realize better fine synchronization of the second liquid crystal layer 50 and the first liquid crystal layer to display 30 light.

In view of the problem of poor reliability of the polarizing plate used in the prior art, one or more of the first polarization functional layer 70, the second polarization functional layer 80 and the third polarization functional layer 90 may be provided as a coating having a polarization function and coated on a corresponding glass substrate.

Preferably, in the liquid crystal display module, no matter how many of the first polarization functional layer 70, the second polarization functional layer 80 and the third polarization functional layer 90 are configured as coatings having polarization functions, the absorption axis of the second polarization functional layer 80 is configured to be perpendicular to the absorption axis of the first polarization functional layer 70 and the third polarization functional layer 90, so as to ensure that better polarization and filtering effects are obtained.

This scheme 2 sets up second polarisation functional layer 80 coating in second glass substrate 40 downside, has simplified a polarisation functional layer in other words, moreover because the moisture-proof of prior art polaroid, heat resistance are not good, sets up this second polarisation functional layer to the coating and sets up inside liquid crystal module, also can alleviate to a certain extent because of the change of polaroid performance takes place liquid crystal panel warpage, liquid crystal display module light leak scheduling problem.

In the embodiment 3, the polarizing plate is not needed to be used, so the process of laminating the polarizing plate is not needed, and the first polarizing functional layer 70, the second polarizing functional layer 80 and the third polarizing functional layer 90 are all provided with coatings with polarizing functions, so that the structure is simplified to the utmost extent, the problems of warping of the liquid crystal panel, light leakage of the liquid crystal module and the like caused by poor moisture resistance and heat resistance of the polarizing plate can be thoroughly avoided, and the reliability of the liquid crystal module is effectively improved.

Based on the liquid crystal display module, the invention also provides a liquid crystal display device, which comprises the liquid crystal display module and a backlight module arranged on the lower side of the liquid crystal display module.
