With the improvement of living standard of people, the large-size liquid crystal panel is more and more popular with consumers, and the change of the size of the liquid crystal panel from small to large has become a trend, so that the production of the large-size panel has good market and development situation. However, due to the limitation of generation line, the simple production of large-sized panels with a single size can cause economic benefits such as low utilization rate of large panels and high production cost, and limit the market development.
At present, the defect is improved by adopting a nesting cutting technology (MMG), namely two types of liquid crystal panels with different sizes are designed on the same glass substrate in a mixed mode, so that the utilization rate of the glass substrate is greatly improved. For example, the G8.5 generation line has a cutting utilization rate of only 75% when a 43-inch liquid crystal panel is cut in a pure mode, and the cutting utilization rate is up to 97% when the 43-inch liquid crystal panel and a 22-inch liquid crystal panel are cut in a mixed mode.
Fig. 1 is a schematic structural view of an embodiment of the MMG panel, which is as shown in fig. 1, and the MMG panel has a transverse length of 2200 mm and a longitudinal length of 2500 mm. The panels numbered 1, 2, 3, 4, 9, 10, 11, and 12 are 22-inch liquid crystal panels. The panels numbered 5, 6, 7, 8, 13, 14, 15, and 16 are 43-inch liquid crystal panels.
However, under the cut-over technology, because the two types of liquid crystal panels have different aperture opening ratios, when the conventional liquid crystal alignment Curing (HVA Curing) technology is adopted, the absorption rates of ultraviolet light (UV) are greatly different, which causes the polymer reaction speeds of the two types of liquid crystal panels to be inconsistent, so that the two types of liquid crystal panels are not aligned in a compatible manner and the display quality of the two types of liquid crystal panels is affected, for example, the liquid crystal panel with a high aperture opening ratio has a problem of broken bright spots due to the fast polymer reaction speed, and the liquid crystal panel with a low aperture opening ratio has a problem of Image Retention (IR) due to the slow polymer reaction speed.

Detailed Description
Where certain terms are used throughout the description and claims to refer to particular components, those skilled in the art will appreciate that manufacturers may refer to the same components by different names. In the present specification and claims, the difference in name is not used as a means for distinguishing between components, but a difference in function of a component is used as a reference for distinguishing between components. The present invention will be described in detail below with reference to the accompanying drawings and examples.
Referring to fig. 2 and 3 together, fig. 2 is a schematic structural diagram of a platform applied to an MMG panel according to an embodiment of the present invention, and fig. 3 is a schematic structural diagram of a platform provided with an MMG panel.
As shown in fig. 2 and 3, the MMG panel 10 includes two types of liquid crystal panels having different aperture ratios, including a first liquid crystal panel 11 and a second liquid crystal panel 12. The stage 20 is provided with a first reflective film 21 and a second reflective film 22 for the two types of liquid crystal panels, respectively. When the MMG panel 10 is disposed on the platform 20 and aligned, the first reflective film 21 and the second reflective film 22 are configured to match the absorption rate of the two types of liquid crystal panels to the same ultraviolet light, so that the two types of liquid crystal panels have the same polymer reaction speed.
Specifically, a first reflective film 21 and a second reflective film 22 are attached on the stage 20. Wherein the first and second reflective films 21 and 22 are sandwiched between the platform 20 and the MMG panel 10 when the MMG panel 10 is disposed on the platform 20. The number of the first reflection film 21 and the second reflection film 22 is at least one, and the first reflection film 21 and the second reflection film 22 are arranged on the platform 20 at intervals. In the present embodiment, two first reflective films 21 and two second reflective films 22 are disposed on the stage 20, wherein the first reflective films 21 and the second reflective films 22 are repeatedly arranged on the stage 20 in the X direction.
When the MMG panel 10 is disposed on the stage 20, the first liquid crystal panel 11 is disposed corresponding to the first reflective film 21, and the second liquid crystal panel 12 is disposed corresponding to the second reflective film 22. Specifically, in the present embodiment, each first reflection film 21 is provided with a plurality of first liquid crystal panels 11, and the plurality of first liquid crystal panels 11 are arranged on the first reflection film 21 at intervals in the Y direction. Each second reflection film 22 is provided with a plurality of second liquid crystal panels 12, and the plurality of second liquid crystal panels 12 are arranged on the second reflection film 22 at intervals along the Y direction.
Preferably, the first and second reflection films 21 and 22 are arranged in a rectangular shape, wherein the first and second reflection films 21 and 22 have the same length, and the width of the first reflection film 21 is greater than the width of the second reflection film 22. In the present embodiment, the width of the first reflection film 21 is equal to the length of the long side of the first liquid crystal panel 11, the width of the second reflection film 22 is equal to the length of the short side of the second liquid crystal panel 12, and the two short sides of the first reflection film 21 and the two short sides of the second reflection film 22 are aligned.
In the present embodiment, the first and second reflection films 21 and 22 have reflectances matched with the aperture ratios of the first and second liquid crystal panels 11 and 12. Specifically, when the aperture ratio of the first liquid crystal panel 11 is larger than the aperture ratio of the second liquid crystal panel 12, the reflectance of the first reflection film 21 is smaller than the reflectance of the second reflection film 22. Stated another way, for different MMG panels 10, it is necessary to select different reflectivities of the first and second reflective films 21, 22 that match the MMG panel 10. That is, the liquid crystal panels have different aperture ratios and the reflectance of the reflective films corresponding to the aperture ratios is also different.
In this embodiment, when the MMG panel 10 is aligned, ultraviolet light is irradiated in the direction of the MMG panel 10, the first reflective film 21 (or the second reflective film 22), and the stage 20, when the aperture ratio of the first liquid crystal panel 11 is larger than the aperture ratio of the second liquid crystal panel 12 and the first reflective film 21 and the second reflective film 22 are attached to the stage 20, since the first reflective film 21 is disposed to correspond to the first liquid crystal panel 11, the second reflective film 22 is disposed to correspond to the second liquid crystal panel 12, and the reflectance of the first reflective film 21 is smaller than that of the second reflective film 22, so that the absorption rate of the first liquid crystal panel 11 for ultraviolet light is equal to that of the second liquid crystal panel 12, thereby making the polymer reaction speed of the first liquid crystal panel 11 equal to that of the second liquid crystal panel 12, thereby, the problem of incompatibility in the alignment of the first liquid crystal panel 11 and the second liquid crystal panel 12 can be avoided.
It will be understood by those skilled in the art that the embodiments shown in fig. 2 and fig. 3 are only for two types of liquid crystal panels and two types of reflective films corresponding to the two types of liquid crystal panels, which are only examples, and the invention is not limited thereto. In other words, when the liquid crystal panel is of another type than the two types, the reflective film is of the same type as the liquid crystal panel, which is also within the scope of the present invention.
Fig. 4 is a flowchart of a method of aligning an MMG panel according to an embodiment of the present invention, wherein the MMG panel includes two types of liquid crystal panels having different aperture ratios, and the two types of liquid crystal panels include a first liquid crystal panel and a second liquid crystal panel.

Specifically, when the aperture ratio of the first liquid crystal panel is greater than the aperture ratio of the second liquid crystal panel, the reflectance of the first reflective film is less than the reflectance of the second reflective film.
Step S102: when the MMG panel is arranged on the platform and is aligned, the first reflecting film and the second reflecting film adjust the absorptivity of the two liquid crystal panels to the same ultraviolet light, so that the two liquid crystal panels have the same polymer reaction speed.
In step S102, when the MMG panel is disposed on the platform, the first reflective film and the second reflective film are sandwiched between the platform and the MMG panel. The first liquid crystal panel and the first reflecting film are arranged correspondingly, the second liquid crystal panel and the second reflecting film are arranged correspondingly, and the first reflecting film and the second reflecting film are arranged on the platform at intervals.
When ultraviolet light shines along the direction of MMG panel, first reflectance coating (or second reflectance coating), platform, aperture ratio when first liquid crystal display panel is greater than the aperture ratio of second liquid crystal display panel, and when the platform is attached to first reflectance coating and second reflectance coating, because the reflectivity of first reflectance coating is less than the reflectivity of second reflectance coating, thereby can adjust the absorptivity of first liquid crystal display panel and second liquid crystal display panel to ultraviolet light and make both absorptance the same to ultraviolet light, and then make the polymer reaction rate of first liquid crystal display panel and second liquid crystal display panel the same, thereby can avoid appearing first liquid crystal display panel and second liquid crystal display panel and join in marriage incompatible problem.
The invention has the beneficial effects that: the invention is applied to the platform of the MMG panel and the method for matching the MMG panel, and the first reflective film and the second reflective film which respectively aim at two types of liquid crystal panels are arranged on the platform; when the MMG panel is arranged on the platform and is aligned, the first reflecting film and the second reflecting film adjust the absorptivity of the two liquid crystal panels to the same ultraviolet light, so that the two liquid crystal panels have the same polymer reaction speed. Through the mode, the problem that the two types of liquid crystal panels in the MMG panel are incompatible in alignment can be solved, and the display quality of the two types of liquid crystal panels can be improved.
