[Prior Art] Liquid crystal display (LCD) has excellent characteristics of lightness, power saving, low radiation, etc., and the development of Thin Film Transistor (TFT) has made liquid crystal display more widely. The color world has the potential to replace the traditional cathode ray tube screen, and there is a large commercial potential. Since the liquid crystal required by the TFT-LCD must have a high resistance value, that is, the same purity, it is easily discarded due to trace contamination in the production process. In terms of current liquid crystal panel manufacturing technology, only 50% of the liquid crystal on the production line is smooth. As a product, three to five percent of the liquid crystals that are contaminated after use must be scrapped. However, liquid crystals are high-priced special-purpose chemicals, so the recycling and purification of waste liquid crystals has clearly become the focus of key technologies. The related art of liquid crystal recycling has been disclosed in the published patents, for example: JP8-27TO1 discloses a method of purifying liquid crystal by adding inorganic salts and organic solvents and heating and collecting them. However, the liquid crystal to which this method is directed is a liquid crystal of a lower purity, and its impurity contains a much larger summer than a TFT liquid crystal, so that it cannot be purified and recovered for a liquid crystal such as a TFT liquid crystal having a high resistance value. On the other hand, the related art for purifying liquid crystal by electrophoresis is mainly disclosed in the application of JP50-108186 - JP51-011079 - JP4-171419 - JP04-288520 - JP08-297290 ^ and JP2002-60752, and the like It is directly used to purify the liquid 1297282 crystal by electrophoresis without combining other techniques. In the above-mentioned JP50-108186, it is disclosed that the method for purifying liquid crystal by using the pumping and reducing electric field and the external electric field is used. When the liquid crystal flows from the storage tank to another storage tank, the electrode is erected on the outer wall of the flowing pipeline to attract the impurity impurity. The effect of the purification is achieved, but since the electrode spacing is greater than 1 cm, a strong electric field cannot be generated, and the liquid crystal is subjected to electrophoresis for too short a time, so the effect of purifying the TFT liquid crystal is limited; in the above JP4-171419, it is revealed that the liquid crystal is filled in a vacuum environment. When the panel is applied, an electric field is applied to the liquid crystal cell to adsorb the impurity impurities, thereby reducing the chance of inhaling the panel. The voltage used is IV, and the electrode spacing is greater than 1 cm, which will not effectively achieve the purpose of purifying the TFT liquid crystal; the aforementioned jp〇4-288520 The method of filling a liquid crystal panel in an applied electric field is disclosed, which directly uses a metal groove filled with a liquid crystal as a cathode, increases the electrode area 'and raises the voltage to 20V, but the electrode spacing is still greater than icm. It is applied to the purification of TFT liquid crystal; in the above case jp08_297290, the electrode spacing is reduced by coating (spUttering) Si〇2 5〇〇v billion 〇lcm and use up the voltage, but the coating of Si〇2 inorganic ions have the opportunity to release the impure thing, and therefore still can not be purified resistance than TFT upgrade to the required range. The techniques of the above four patent applications are directed to liquid crystals with lower purity requirements, and can be purified by using STN liquid crystal as an index, and the purification technique thereof is not sufficient for effectively purifying the TFT of the present invention or higher purity and high resistance. liquid crystal. As described in the above JP2002-60752, the method of purifying high-resistance liquid crystal by electrophoresis in a vacuum environment is disclosed, and the electrode is purified by electrophoresis at a voltage of 3 GGV, and the paste electrode is repeatedly washed, and 2 After 17 hours, the purification of the high-resistance liquid crystal was completed. However, the electrode area was only l〇cm2, and the liquid crystal throughput was only about 3 μm at a time, and it could not be directly applied to a large-scale purification plant operation. 1297282 SUMMARY OF THE INVENTION In order to solve the shortcomings of the above-mentioned prior art for high resistance and high purity liquid crystal recovery, the object of the present invention is to establish a purification technology suitable for factory-level, large amount of TFT or higher purity and resistance liquid crystal. Including the purification process and equipment, such liquid crystals currently use TFT liquid crystal as an index, and the purity thereof requires that the metal ion impurity content is below 5 ppb, and the resistance value must be as high as i 〇 13 Qcm or more. The main object of the present invention is to provide a high-resistance liquid crystal purification method, which mainly combines the salt adsorption method and the electrophoresis method to purify the waste liquid crystal, so that the resistance of the recovered liquid crystal can reach more than cm. The foregoing method comprises at least the steps of: contacting the contaminated waste liquid crystal with an inorganic salt for adsorption; filtering the liquid crystal adsorbed by the inorganic salt to obtain a sub-purified liquid crystal; and finally, performing the electrophoresis of the sub-purified liquid crystal to remove The impurities remaining in the liquid crystal, wherein the inorganic salt adsorption process can be carried out at room temperature without adding a solvent. The type of the above inorganic salt may be selected from at least aluminum hydride xylide, slylgel, activated alumina, zeolite, titanium oxide, and the like. One. The preferred method for the waste liquid crystal resistance of the above method is 10 uQcm~l〇13Qem.

The above-mentioned electric socket can freely expand or expand the liquid crystal amount to increase or decrease the number of electrode sheets, and the area of the Hongji sheet is not subject to _. The electrode pad holder is of a detachable or fixed design. β The foregoing electrode material may be platinum, silver, zinc, etc., preferably platinum, and the distance between the electrode sheets is preferably. Preferably, the electrode pad holder and the groove are made of (4) η. The liquid crystal purification method used in the invention can effectively remove the impurities in the liquid crystal in a short time to reach the specification of use, compared with the inorganic salt and the organic solute used by the conventional technology to win 277391. When the green color is required to be #3, the present invention takes only 3 minutes for the inorganic salt adsorption method; in addition, in the electrophoresis method, the electrophoresis time required for the patented JP2002060752 patent technology is 17 hours, and the present invention uses The electrophoresis device takes only 3 hours to achieve a similar effect, and the amount of liquid crystal processed is much larger than this technology.

The high voltage of 700V is electrophoresed in an argon atmosphere, and it takes only 3 hours to reach the purification requirement of TFr liquid crystal. The amount of liquid crystal can be processed up to 13 〇m b at a time, and it is not necessary to take out the electrode sheet repeatedly, which can be effectively applied to In the mass production process. The invention is directed to the technology of efficiently purifying TFT and higher resistance liquid crystal by inorganic salt adsorption method and electrophoresis method, and the operation mode thereof is as follows: inorganic salt adsorption method, inorganic salt adsorption method is liquid crystal and l〇wt% The AC61 (containing 99.3% or more of the oxidation) was mixed and stirred for 20 minutes, and the mixture was allowed to stand for 1 minute after the stirring, and the purified liquid crystal was obtained by filtration using a 0.2//m PTFE filter. The electrophoresis method purifies the liquid crystal by placing the liquid crystal between the electrode sheets. When the electrode is connected with a high voltage, the 1929728 (5〇〇~ volt) ion moves in the electric field, from the liquid crystal to the electrode surface, to achieve separation. effect. The electrophoresis operation procedure is as follows: 1. Discharge the platinum electrode sheet in the electrophoresis tank according to the rules of positive and negative phases. 2.
