Description

200538829 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a liquid crystal panel assembly process (1 iquid crystal panel assembling process) and a liquid crystal panel, and in particular, to a method for solving the problem of excessive liquid crystal filling. Liquid crystal panel assembly process and liquid crystal panel with gravitymura phenomenon. [Previous technology] For the rapid progress of the multimedia society, most of them have benefited from the leaps and bounds of semi-conductor devices or human-machine display devices. As far as displays are concerned, it has high picture quality, good space utilization efficiency, and low power consumption. Liquid crystal display (LCD) with superior characteristics such as non-rotational shooting has gradually become the mainstream of the market. The liquid crystal panel of a liquid crystal display is generally composed of an upper substrate, a lower substrate, and a liquid crystal disposed therebetween, and a sealing member is used around the display panel to seal the liquid crystal between the upper substrate and the lower substrate. . The material of the seal is usually heat-cured (heat-cured) glue or ultraviolet-cured (u 11 r a v i ο 1 e t c u r i n g) glue, which is cured by heating or ultraviolet irradiation, respectively. The sealing member not only has a function of sealing the liquid crystal between the upper substrate and the lower substrate ', but also has a function of maintaining a cell gap (c e 1 1 g a p). FIG. 1 is not a flowchart of a conventional LCD panel assembly process, and FIG. 2 is a schematic diagram of a patterned seal of a conventional LCD panel. Please refer to FIG. 1 and FIG. 2. The conventional LCD panel assembly process using the One Drop Fill (ODF) method first provides a first substrate 1 1 ο, and seals 1 2 0 in a square frame. The form is coated on the first substrate 110, as in step s110. Pick up

13497twf.ptd Page 7 200538829 V. Description of the invention (2) Drop the liquid crystal 130 on the center of the first substrate 1 1 0 and let the liquid crystal 1 30 flow to the entire area surrounded by the seal 1 2 0 Range, as in step S 1 2 0. Then, a second substrate 1 40 is pressed onto the first substrate 1 1 0 in a vacuum state, and the first substrate 110 and the second substrate 1 4 0 are bonded by the sealing member 120, as in step S 1 3 0 . After that, the sealing member 120 is cured by ultraviolet rays to seal the liquid crystal 130 therein, as in step S 1 40. Finally, since the material of the sealing member 120 is usually a mixture of a heat curing adhesive and an ultraviolet curing adhesive, it is necessary to perform baking again to completely cure the sealing member 120, such as step S150. It is worth noting that in the conventional liquid crystal panel assembly process using the drip injection method, since the amount of the dropped liquid crystal is difficult to control, it is impossible to maintain uniform cell gaps throughout the LCD panel after assembly. Since the size of the cell gap is also the thickness of the liquid crystal layer, it has a great influence on the display effect of the liquid crystal panel, so that the display quality of the liquid crystal panel will be poor. In addition, since the panel is placed in an upright position during use, excessive liquid crystals will be further affected by gravity and flow downward, resulting in a more uneven gravity distribution of the liquid crystal distribution, which in turn affects the display quality of the liquid crystal panel. SUMMARY OF THE INVENTION The object of the present invention is to provide a liquid crystal panel assembly process and a liquid crystal panel, which are suitable for solving the problem of uneven gravity caused by excessive liquid crystal.

A patterned sealing member 42 0 is disposed on the first substrate 41 0. The patterned seal 4 2 0 includes, for example, a frame adhesive, which is a thermal curing adhesive (such as Mitsui Chemical's Struct bond XN-21 series), and a light curing adhesive (such as Three Bond Co., Ltd.). 30Y series) or a mixture of light-curing adhesive and heat-curing adhesive (such as the Struct bond XUR series of M'sui Chemical), the S series of Sekisui Chemical's, the TechSeal series of ShinEtsu Chemical's, and Henkel Loctite (Henkel Loctite Tech's X series, etc.).

Alternatively, the buffers 432 may be scattered without being adjacent to each other, as shown in FIG. 4B. Next, for example, the liquid crystal 440 is disposed in the display area 43 of the first panel 410 by using a drop-injection method, as in step 4320. Of course, the liquid crystal 44 may also be disposed on a portion of the second substrate 450 corresponding to the display area 43.

200538829 V. Description of the invention (8) The liquid crystal 4 4 0 enters the buffer area 4 3 2 communicating with the display area 4 3 0, as in step S3 7 0 ° In addition, after step S 3 7 0, for example, the liquid crystal panel 4 0 0 is detected to determine whether gravity unevenness is generated, as in step S 380. If the test result shows that the liquid crystal 4 4 0 is still excessive, the process returns to step S 3 6 0 and cuts a portion of the patterned sealing member 4 2 0 to communicate the display area 4 3 0 with another buffer 4 32. If it is found that the LCD panel 400 has no weight unevenness, the entire assembly process of the LCD panel 400 is completed. As mentioned above, in the assembly process of the liquid crystal panel of the first embodiment, since the patterned seals are designed with a plurality of buffer areas having different areas, when the liquid crystal is excessive, the laser can be used to open the buffer area to accommodate the excess. Liquid crystal, thereby solving the problem of gravity unevenness_display quality of the liquid crystal panel. In addition, because the areas of the buffers are different, the best adjustment effect can be obtained by selecting different buffers. In the above-mentioned embodiment, since the patterned seal and each buffer area are cured first, it is necessary to further add a detection program to determine whether there is a gravity unevenness. After that, the seal is cut by, for example, the aforementioned laser light, so that the liquid crystal material located in the display area of the liquid crystal panel can enter a predetermined number of buffers. Then, the liquid crystal panel is squeezed so that the remaining liquid crystal material flows out of the display area and flows into the buffer area. Please refer to Fig. 3B. Generally speaking, the liquid crystal panels manufactured in the same batch should have approximately the same cell volume, and the liquid crystal drip volume is also the same. Therefore, after the assembly of the same batch of LCD panels is completed (such as step S 1 0), several LCD panels will be tested first to confirm that they are

V. Description of the invention (9) Whether there is uneven gravity, such as step S20. If there is a defect of uneven gravity, it is necessary to use a try and error method to find the optimal area of the buffer area required to accommodate the excess liquid crystal material, such as step S30. Then, in other batches of liquid crystal panels in the same batch, the patterned seals can be cut according to the above results, so as to obtain a buffer area with an optimal area to accommodate the excess liquid crystal material, as in step S40. In addition, since the area of each buffer area is not exactly the same, when the buffer area is used to accommodate excess liquid crystal, the best adjustment effect can be obtained by selecting different buffer areas. For example, if after trial and error method 'it is determined that a laser light cutting seal is needed to allow the liquid crystal material to enter a buffer unit with a unit volume of 1 and a unit volume of 2, then other liquid crystal cells in the same batch can use 1 As a result, the laser light cutting seal is directly used to allow the liquid crystal material to enter a buffer unit with a unit volume of 3, which can save time for repair and increase productivity. 4A, the liquid crystal panel 400 of the present invention is mainly composed of a first substrate 410, a patterned seal 420, a liquid crystal layer 440, and a second substrate 450. The patterned sealing member 4 2 0 and the liquid crystal layer 440 are disposed between the first substrate 4 0 and the second substrate 4 50. The patterned sealing member 42 0 includes an outer frame 42 2 and at least one buffer wall 424. The outer frame 4 2 2 surrounds the liquid crystal layer 440. The buffer wall 424 and a part of the outer frame 4 2 2 define a plurality of buffer areas 4 3 2 having different areas. A part of the liquid crystal layer 4 4 0 is, for example, located in at least one buffer area 432, or all the buffer areas 432 are not provided with the liquid crystal layer 440. It is worth noting that the assembling process of the liquid crystal panel 400 according to the first embodiment of the present invention is not limited to matching with the first embodiment of the present invention as shown in FIG. 3A.

Description of the invention (10) The LCD panel assembly process can also be combined with the LCD panel assembly process of the second embodiment of the present invention described below, or other LCD panel assembly processes. In other words, as long as the patterned sealing member of the liquid crystal panel has a plurality of buffer regions with different sizes, it belongs to the scope of the present invention. Fig. 5 shows a flowchart of an assembly process of a liquid crystal panel according to a second embodiment of the present invention, and Figs. 6A to 6E show schematic diagrams of five liquid crystal panels according to the second embodiment of the present invention. Please refer to FIG. 5 and FIG. 6A. The liquid crystal panel assembly process of the second embodiment of the present invention first provides a first substrate 610 and a second substrate 650, as step S510. The types of the first substrate 610 and the second substrate 650 may be the same as those of the first embodiment. A patterned sealing member 6 2 0 is disposed on the first substrate 610. The material selection 1 of the patterned seal 620 may be the same as that of the patterned seal 420 of FIG. 4A. In this embodiment, a mixture of a light-curing adhesive and a heat-curing adhesive is used as an example. The patterned seal 620 defines a display area 630 and a plurality of buffer areas 632. The patterned seal 620 may include an outer frame 622, at least one common wall 624, and a plurality of partition walls 626. The two ends of each partition wall 626 are respectively connected to the outer frame 622 and the common wall 6 24 to separate the outer frame 6 2 2 and the common wall 6 24 into a plurality of buffer zones 632 as described above. In other words, the buffer areas 632 are adjacent to each other and arranged in a row, for example, with the partition wall 626. The part of the area surrounded by the outer frame 6 2 2 except the buffer area 6 3 2 is a display area 6 3 0. The areas of the buffer regions 6 3 2 are, for example, the same or different from each other. In another embodiment of the present invention, the outer frame 6 2 2 and the common wall 6 2 4 are formed of, for example, a light-curing adhesive, and the partition wall 6 2 6 is formed of, for example, a heat-curing adhesive.

13497twf.ptd Page 16 200538829 V. Description of the invention (11) In another embodiment of the present invention, the outer frame 6 2 2 and the common wall 6 2 4 are formed of, for example, a mixture of a light curing adhesive and a heat curing adhesive. The partition wall 6 2 6 is formed of, for example, a thermosetting adhesive. Next, the liquid crystal 6 40 is arranged in the display area 6 30 on the first substrate 6 10 by, for example, a dropping injection method, as in step s 5 2 0. Of course, according to another embodiment of the present invention, the liquid crystal 640 may also be disposed on a portion of the second substrate 650 corresponding to the display area 630. Then, for example, in a vacuum environment, the second substrate 6 5 0 is adhered to the first substrate 6 0 by the adhesiveness of the patterned sealing member 6 2 0, as in step S530. At this time, the liquid crystal 640 does not enter the buffer area 632 due to the blocking of the common wall 624 and the partition wall 626. After that, a first curing step is performed to cure the patterned sealing member 6 2 0 outside the frame 6 2 2 and the common wall 6 24, as in step S54. In this embodiment, the outer frame 622 and the common wall 624 are cured, for example, by using a photomask and irradiating the outer frame 6 2 2 and the common wall 624 with ultraviolet exposure. Among them, the part of the photomask covering the partition wall 6 2 6 is ′ to keep it thin and hardened without being irradiated by ultraviolet rays. Of course, the light used for exposure is not limited to ultraviolet light, it should be determined according to the characteristics of the light curing adhesive used.

Next, the first substrate 610 and the second substrate 650 are pressurized so that the excess liquid crystal 6 3 0 breaks through the uncured portion of the patterned seal 6 2 0, that is, breaks through the partition wall 6 2 6 and enters at least one buffer 6 32, as in step s 5 5 0. In this way, the buffer area 6 32 can be used to accommodate the excess liquid crystal 6 3 0, thereby solving the gravity unevenness caused by the excess liquid crystal 6 3 0. In this embodiment, since both the outer frame 6 2 2 and the common wall 6 24 have been cured, the liquid crystal 63 will be restricted by the common wall 624 when entering the buffer area 6 32, and only from the buffer areas on both sides. 6 3 2 began to enter one by one. In this way, the number of buffers 6 3 2 that the liquid crystal 6 3 0 enters can be easily controlled, so that the thickness of the liquid crystal 6 3 0 is optimal throughout the liquid crystal panel without the liquid crystal 6 3 〇. Too few counter-effects. 1 Finally, a second curing step is performed to cure the uncured portion of the patterned seal 620, that is, the partition wall 626, as in step s56. In the embodiment in which a mixture of a light-curing adhesive and a heat-curing adhesive is used to form a patterned seal, the method of performing the second curing step to cure the partition wall 6 2 6 is, for example, first performing UV exposure, and after performing UV exposure, For example, the entire patterned seal 6 2 0 is baked.

The purpose of this step is to partially cure the cured sealant inside the patterned sealing member 620, so that the step of UV exposure and the required cost can be omitted. In addition, referring to FIG. 6B, the common wall 6 2 4 of the patterned sealing member 6 2 0 may be a plurality of pieces. The buffer zone 632 may be arranged on each side of the outer frame 6 2 2 and is not limited to one side. The area sizes of the buffer zones 6 3 2 may be the same as or different from each other. Of course, the arrangement of the buffers 6 3 2 can also be arranged from large to small, or from small to large as shown in FIG. 6 c. Alternatively, the layout of the patterned seal 62 may be as shown in Figs. 6D and 6E. Among them, the patterned seal 6 2 0 shown in FIG. 6E omits the design of the common wall, and the display is defined only by the combination of the outer frame 6 2 2 and the buffer wall 6 2 6. The area 6 3 0 and the buffer 6 3 2. Of course, the assembly process of the liquid crystal panel 6 0 1 shown in FIGS. 6A to 6E is not limited to the assembly process of the liquid crystal panel shown in FIG. 5 according to the second embodiment of the present invention. The liquid crystal panel assembly process of the first embodiment of the invention, or other liquid crystal panel assembly processes. Compared with the first embodiment of the present invention, the second embodiment of the present invention cures the patterned seal in a two-curing process, and allows more than liquid crystal to break through the uncured pattern between the two-curing processes. The seal is entered into the buffer zone, so there is no need to determine the volume of the buffer zone by trial and error, and then the patterned seal is cut to allow excess liquid crystal to enter the buffer zone. In other words, t, ϊ; m: i In the assembly process of the panel, only the patterned seals defining the buffer zone need to contain soft or uncured parts, and the excess liquid crystal will automatically determine the need during the extrusion f process. How much buffer space is used. In this way, the process operation interval can be increased.

Description of the invention (14) window), can not only improve the production yield, but also reduce the precision requirements of the process equipment, thereby greatly reducing the cost of LCD panel production and quality control. Please refer to FIG. 6E again. In this embodiment, the number of the patterned seals 6 2 0 is multiple (here, 6 is taken as an example), and each patterned seal 6 2 0 defines a display. District 6 3 0. The size of each display area 630 depends on the size requirements of the LCD panel. In the subsequent process, the first substrate 6 1 0 and the second substrate 6 50 are cut into multiple parts along the dotted line D 1, for example, and each part can be a liquid crystal panel. Each liquid crystal panel includes, for example, a patterned sealing member 6 2 0. It is worth noting that the cutting lines of the first substrate 610 and the second substrate 650 do not necessarily overlap each other, and the dotted line D 1 is for illustration purposes only. As mentioned above, this method can be used for mass production of liquid crystal panels to reduce production time and cost, and of course, it can also be applied to other embodiments of the present invention. In summary, in the process of assembling the liquid crystal panel and the liquid crystal panel of the present invention, the entire sealing member is directly cured, and when the liquid crystal is found to be excessive, the buffer area is opened to accommodate the excessive liquid crystal. At the same time, buffers with different areas can obtain a more appropriate accommodating area for excess liquid crystals with different volumes, and save the time required to open the buffers. Alternatively, the display area and a plurality of buffer areas are defined by the seal. For example, at least the periphery of the seal is cured first, and then excess liquid crystal in the display area is pressed into the buffer area, and then the seal defining the buffer area is cured. Because the patterned seal is designed with a buffer zone, the liquid crystal panel assembly process and liquid crystal panel of the present invention can solve the phenomenon of uneven gravity caused by excessive liquid crystal, and improve the display of the liquid crystal panel.
