preparation example Construction

[0029] The present invention also provides a method for preparing a liquid crystal display device, which comprises placing liquid crystal and electrodes into two substrates, and then contacting a material for preventing electrode corrosion with a terminal portion of the substrate, wherein the material for preventing electrode corrosion It is the material for preventing electrode corrosion provided by the present invention. Specifically, in the present invention, the material for preventing electrode corrosion is made into a film, and then the obtained film is hot-pressed and covered on the terminal part of the substrate of the liquid crystal display device, so that the electrode corrosion prevention material covers the terminal part electrode without affecting the binding The fixed driver IC and flexible circuit board shall prevail.

[0030] In the present invention, the anti-corrosion performance of the electrode anti-corrosion material is represented by the time that the liq...

Embodiment 1

[0033] This example is used to illustrate the preparation method of the material for preventing electrode corrosion provided by the present invention.

[0034] 1 gram of solid bisphenol A epoxy resin with a degree of polymerization of 2.5 (produced by Baling Petrochemical Company, EP 01661-310) was added to 200 ml of methyl ethyl ketone, and then 99 grams of liquid bisphenol with a degree of polymerization of 1.5 was added after stirring evenly. A epoxy resin (produced by Baling Petrochemical Company, EP 01551-310), add 10 grams of curing agent 2-ethyl 4-methylimidazole (Shanghai Chenri Chemical Co., Ltd.) after continuing to stir for 10 minutes, and continue to stir for 30 minutes , and then add 1 gram of acrylic plastic particles with a diameter of 8 microns. After stirring again for 10 minutes, the obtained mixture was all coated on a layer of release film by a roller coating process. After natural air-drying to remove the solvent, a thickness of 0.02 The millimeter-sized f...

Abstract

A material for preventing electrode corrosion, wherein the material contains a hydrophobic composition, and the hydrophobic composition contains a resin with a curing temperature lower than 190°C and a curing agent for curing the resin. The anti-electrode corrosion material provided by the invention can be used to prevent the electrodes at the terminals of the liquid crystal display device from being corroded, so that the service life of the electrodes is increased from 5000 hours to more than 8000 hours.

Description

technical field [0001] The present invention relates to a material for anti-corrosion, in particular to a material for anti-corrosion of an electrode for preventing the electrode of a terminal part in a liquid crystal display device from being corroded, a liquid crystal display device containing the material and a preparation method thereof. Background technique [0002] Currently, liquid crystal display devices are usually figure 1 As shown, there are a liquid crystal layer 103, a pair of substrates 101 and 102 with an ITO conductive film sandwiching the liquid crystal layer, an alignment layer 104, an electrode 105, an anisotropic conductive film 106, a flexible circuit board 107, a driver IC 108, and a silica gel 109 , the frame adhesive 110 . The substrate 102 leads out all the electrodes 105 in the entire liquid crystal display device through the indium tin oxide conductive film on the terminal surface of the substrate 102 . The driver IC 108 and the wiring 105 are co...
