The liquid crystal is sealed by the sealant on the two substrates. At present, there are two main types of frame seals made in liquid crystal displays: - the type is a heat-curable frame, and the other is a UV-cured frame glue; the former usually requires a long baking time and a complicated processing procedure, and The latter is basically a one-component UV-curable % oxygen relay that requires a fine-grained light to be cured in a short period of time. For the new generation of TFTLCD processes, it helps process time. shorten. In the fourth generation of TFT LCD production methods, the above two substrates are mostly heated*5L, and then (four) several stages of heating and a combination of two crystals are formed. The liquid crystal cell is woven with liquid crystal, and finally sealed to complete the thin film transistor liquid crystal pure liquid crystal panel. The shortcomings of this technique are that the effective _ rate of _ crystal is only a percentage to 80 Å. The other is the improvement of the granule liquid crystal (4) for more than 20 hours (taking the 17-inch DFT LCD as an example). The method of 0Dff^TFT LCD adopts a new liquid crystal injection technology called liquid crystal dropping the edge of the needle-like substrate to form a frame with a frame glue, and then using it in the frame to make the display: the internal machine quantitatively drops in large density.

The difficulty of explosion has greatly reduced the production cost. However, in the process of liquid crystal dripping, it will be straight with the frame glue. Glue contamination of liquid crystals, and maintaining good adhesion to glass is the focus of the development of new frame sealant composition; in order to solve these problems, many different components of the sealant have been proposed, for example: the invention patents already published in the Republic of China The disclosure of the first publication of the present invention proposes a type of photo-hardening and heat-hardening type of sealant; the invention patent publication No. 5, No. 4, No. 4, discloses a curable resin containing light and/or heat hardening and polymerization. Starter agent, etc. a sealing agent for a liquid crystal display element; the other is as disclosed in Japanese Patent Laid-Open No. 2, No. 4, No. 996, No. 2, No. 2, and No. 7 of the Invention Patent Publication No. 7 </ br> </ br> Polymer (EpGxy(4)^prepolymer), UV curing initiator (UV curing), heat curing initiator (He station curing agent), powder (Filler), other additives (〇ther additive), etc. The adhesion generated by UV exposure and two-temperature hot baking is still not comparable to the adhesion of the pure thermosetting sealant used in the conventional process. [Inventive content] The main purpose of this month is to give a kind of The use of the Thermaj curing initiator component is still applicable to thermal curing, and achieves the same strength of the sealant composition as the current commercial liquid crystal dropping method. Another object of the present invention is to propose an application. Yu Yi ... the DF crystal dropping method) does not produce the liquid crystal display device written sealant composition which will neither contaminate the liquid crystal before or after curing, do not cause changes in the electrical characteristics of the liquid crystal. The sealant composition proposed by the present invention mainly comprises the following components: urethane (meth)acrylate olig0mer, epoxy prepolymer (Ep〇xy acrylate prepolymer), acrylamide A vinegar (aiiyi ure1:hane), followed by a promoter (such as acrylate phosphate compound), a diluent (such as acrylic acid acrylate monomer (acrylate 111011011161:)), | external hardening initiator ( 111 丨〇 丨〇 1 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( -5if.^ ^ Degree ratio ^^ material pure ===== Lai Mi strong and strong hair _ more than the application of the seam _ capacity, the way to apply] Hyun match diagram description as follows: 中,—攀面面_ The strength of the process of the panel, after the middle of the process _ the required use of indium tin oxide conductive glass _ ^ glue on the liquid crystal panel is low _ to consider, choose the higher purity of the ultraviolet light hard motion = specific resistance to make up _ Selection, the purity of the raw materials of the raw materials has a huge impact, so the raw materials used in the unhardened scent resistance must be lower than the leakage m GG ( Under pA, and the specific impedance change to liquid crystal must be less than 8 〇 / 〇. The composition of ODF glue is mainly blended with the following components: oligomers, monomers, initiators, powder additives , 纟Additions, etc. ± Contains polyurethane (meth) acetoacetate oligopolymer, epoxy acrylate prepolymer, propylene urethane, acrylic acid ester compound, UV curing initiator, and powder ( The viscous composition suitable for liquid crystal dropping method (One Drop Π11, ODF) according to the present invention comprises the following components: urethane (meth) acrylate oligomer ), (2) Ep〇xy acrylate prepolymer, (3) allyl urethane, (4) an accelerator (such as an acrylate phosphate compound) And (5) a diluent (such as an acryiate monomer), (6) an ultraviolet curing agent, and (7) a powder oligomer type substantially including: an aromatic melamine Aromatic urethane acrylate Aliphatic urethane acrylate, polycarbonate urethane acrylate, epoxy acrylate 7 200804448 (epoxy acrylate), polyether acrylate, polyether acrylate Polyester acrylate, silicone acrylate form, and the like. Since the oligomer (〇lig〇mer) is the main body of the sealant, and the high molecular weight raw material has a low mobility, the effect on the liquid crystal is also relatively reduced, so according to a preferred embodiment of the present invention, the oligomer is Commercially available products with a molecular weight (Mw) of more than 1 Å are selected, and S-type acrylate and epoxy-based acrylic acid can be used together to obtain the best physical properties. In addition to the oligomer, the preferred embodiment of the present invention also adds propylene polyurethane to increase the reaction rate, and the light sensitivity of the gQDF gel to the outer line is not sacrificed. The adhesion of the glass, generally higher requirements for the curing speed, should be selected from the polyfunctional acrylic acid, so the commonly used acrylamine § is mainly based on two official = machine; In addition, it is preferable to increase the binding of the glaze by the promotion, and it is preferable to use a polymer type acrylic acid and a polymer type coupling agent, but the effect of the accelerator on the specific impedance of the liquid crystal is large, and is added.
