Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a liquid crystal display, and more particularly to a method for sealing a liquid crystal material by using a drop-injection (〇nedr 〇pfi 1 1, 0 DF) process. The liquid crystal between the two substrates is inferior. [Prior art] A liquid crystal display generally includes two opposite glass substrates and a liquid crystal layer sandwiched therebetween. In detail, the assembling process of the two glass substrates includes the following steps. First, using screen printing (si 1 kscreening) or screen printing 1J (screenprinting) technology, apply an adhesive, and leave an opening for a little After the liquid crystal injection. After applying the adhesive, a spacer is set on one of the two substrates to maintain a precise cell gap (ce 1 1 gap) (between 3-10 microns) between the two substrates. ). Generally, the spacer is sprayed on glass or plastic beads on one of the two substrates or a photolithography process is used to make a photo-spacer on one of the two substrates by using a resin. The substrate was then aligned and heat-pressed to complete the cross-linking of the polymer. After the two glass substrates are assembled, they are cut into individual LCD cells. After the liquid crystal material is vacuum-injected into the liquid crystal, the openings left before are sealed. Traditionally, the opening-sealing process is performed in a pressure chamber to squeeze out excess liquid crystal material from the liquid crystal display and introduce the sealing resin into the opening of the liquid crystal display. In detail, increasing the air pressure in the chamber will cause pressure on the outer surface of the liquid crystal display unit, and the excess liquid crystal material will be forced out before the sealing resin is applied.

Description of the invention (3) A liquid crystal display manufacturing method in which a liquid crystal material is sealed between two substrates. This method can allow a larger liquid crystal dripping allowable processing window than the conventional method (process window). The basic steps of the dripping injection method are described below. First, an adhesive (such as an ultraviolet curable sealant) is formed on a peripheral portion of a substrate, and the liquid crystal material is dripped on another substrate. The two substrates are separated into a vacuum chamber. When the two substrates are still under the chamber pressure, the side positions (1 a t e r a 1 ρ s i t i ο η) of the two substrates are aligned with each other. The pressure in the vacuum chamber is then reduced, and the two substrates are assembled together under a low pressure condition so that one substrate is stacked on the other substrate. Thereafter, the sealant is cured by applying an appropriate radiation (for example, an ultraviolet light). To achieve the above and other objectives, the adhesive is cured in a chamber maintained at a pressure greater than atmospheric pressure. The increased air pressure in the chamber generates pressure on the outer surfaces of the pair of substrates, causing one of the pair of substrates of the finished liquid crystal display to be recessed toward the other substrate. Therefore, although the dripped liquid crystal material cannot completely fill the space between the two substrates after one substrate is stacked on the other substrate, the expected void can be caused by the substrate being placed on a substrate when the adhesive is cured. Removed under atmospheric pressure. According to a feature of the present invention, the method further includes a step of heating the two substrates during the curing process of the adhesive, so that the thermoplastic gap between the two substrates of the liquid crystal display finished product is deformed to have different profiles. In order to make the above and other objects, features, and advantages of the present invention clearer

Description of the invention (5) ratio) 〇 A method for manufacturing a liquid crystal display according to an embodiment of the present invention will be described below with reference to FIGS. 1-2. First, an adhesive agent 300 is coated on the inner surface 100a or 110a of one of the substrates 100 and 110. In this embodiment, the adhesive 130 is made of a resin material, and the resin material can be subsequently cured by a radiation such as ultraviolet light. It should be understood that the adhesive 130 may be pre-cured (p r e-c u r e d) before proceeding to the subsequent steps. After or the liquid crystal material is dropped / hosted on another substrate, the substrates 100 and 110 are placed in a chamber 200. In detail, the substrate 1 10 is placed on a platform 2 10, and then the substrate 1 0 is placed on the substrate 1 1 0 and separated from the substrate 1 1 0 so that the insides of the two substrates are Surfaces 100a and 1 10a face each other. When the two substrates are still under room pressure, the lateral positions of the two substrates are aligned with each other. The air in the chamber 200 is then evacuated, and the two substrates 100 and 1 10 are combined together after reaching a pressure lower than atmospheric pressure so that one substrate is stacked on the other substrate (see Figure 1). The air pressure in the chamber 200 was then restored to atmospheric pressure. The liquid crystal material thus spreads to fill the space between the two substrates 100 and 110, and extends to the inner periphery of the adhesive 130. At this time, as shown in FIG. 1, when viewed from the sides of the substrates 100 and 1 10, all the spacers 120, 122, 124, 126, and 128 have approximately the same cross section. Thereafter, a transparent plate (for example, a quartz plate 220) is moved toward the two substrates 100 and 110 to increase the air pressure in the chamber. When a pressure greater than atmospheric pressure is reached, the adhesive is cured by applying a suitable radiation, which may enter from a UV light source 2 3 0 through the quartz plate 2 2 0

Description of the invention (6) Ultraviolet light of the adhesive 1 3 0. It should be noted that the increased air pressure in the chamber 200 generates a pressure on the outer surfaces 1 0 b and 1 1 Ob of these substrates, so that the pair of substrates 1 0 0 and 1 1 0 are recessed toward the other substrate ( (See Fig. 2), thereby preparing a finished product of the liquid crystal display. In addition, as shown in FIG. 3, the pressure generated by the air pressure can cause only the substrate 100 to be depressed toward the substrate 110. It should be noted that the spacer used in the present invention can be made of a thermoplastic material, and a heating step can be performed in the curing process of the adhesive to make the thermoplastic spacer (for example, the spacer 1 2 0, 1 2 2, 1 2 4, 1 2 6 and 1 2 8) are deformed to have different cross sections, thereby generating different cell gaps at different gaps in the finished product of the liquid crystal display (see FIG. 2 or 3). When studying the conventional drop-injection method, the inventors of the present case found that they needed to drip a very precise amount of liquid crystal material onto the substrate. When the drip volume of the liquid crystal material is lower than the minimum allowable dispensing quantity (hereinafter referred to as π V mi η π), the dripped liquid crystal material cannot completely fill the space between the two substrates, and A negative pressure may exist between the pair of substrates of the finished liquid crystal display. As a result, voids are easily formed in the liquid crystal layer of the finished liquid crystal display panel. When the dripping of the liquid crystal material exceeds the maximum allowable dispensing quantity (hereinafter referred to as n Vmax), it is easy to observe gravity mura (large range) during the final inspection. Pixel defects), wherein the final inspection process is to place the finished product of the liquid crystal display in a manner perpendicular to the horizontal plane and heat it. Mura defects are defined as when the light emitting area (basic

Description of the invention (7) The pixels on the board are different or inconsistent with the adjacent area surrounding the defect, which is also called patterned brightness non-uniformity (BNU). ). Any LCD display with holes or uneven gravity will be considered defective. Therefore, one of the characteristics of the traditional drip injection method is that the drip volume of the liquid crystal material must be accurately controlled within a very narrow allowable processing range (defined between Vmin and Vmax). In addition, when the conventional drip injection method is used for manufacturing a large-size liquid crystal display panel, the allowable processing range of the conventional drip injection method is more noticeably narrow. On the other hand, even when the liquid crystal material is lower than the previously defined Vniin, the aforementioned method of the present invention can achieve the same result as the conventional method, that is, the aforementioned method of the present invention can allow a larger allowable processing range than the conventional method. . In the method of the present invention, since the liquid crystal material dripped is not enough to completely fill the space between the substrates, there may still be extra space when one substrate is stacked on another substrate. However, the extra space can be eliminated when the substrate is placed in a chamber having a pressure higher than atmospheric pressure to cure the adhesive, so that the liquid crystal display panel finished product has no voids. This is because the air pressure of the chamber greater than the atmospheric pressure will generate pressure on the outer surfaces of the pair of substrates, causing the pair of substrates to be recessed toward the other substrate, thereby eliminating the extra space. Although the present invention has been disclosed in the foregoing preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the scope of the appended patent application.
