The heat is concentrated in the water, and the energy is only used to radiate the moisture, but not to heat other materials. Therefore, the material of the flat display is not degraded. “This can greatly increase the“ efficiency ”to help high-quality materials,” and can be complete. Thorough and fast drying is conducive to mass production, and has the advantages of fast, simple, and low cost. "[Previous technology] As various flat display technologies perform better than cathode ray tube mode workers," they have been continuously developed, such as LCD display (LCDs, Liquid Crystal Dlsplays), field emission display / (feDs, Flldd Emission Displays), plasma TV (pDps, p

Description of the invention (2) As the name suggests, the liquid crystal display uses the optical characteristics of liquid crystals to achieve the effect shown above. As long as the liquid crystals are poured into two pieces of evacuated glass, the voltage is added, and the voltage is appropriately controlled. The pitch of the glass plate can change the deflection characteristics of the incident light, but it is not easy to make it in practice. At present, the following are most commonly cited by newspaper media: TN, STN, a-Si TFTs, and p〇ly- Si TFTs can be divided into active matrix (Active Mat rix) and passive matrix (Passive Matrix) two general TN and STN types belong to the latter, while the TFT type currently causing domestic manufacturers investment boom is the former. The simple internal structure of the LCD panel includes its upper and lower Covered by two light-transmitting glass substrates, the interior contains a backlight (Polar), a polarizing plate (Polarizing Filter), a transparent conductive layer (Transparent E 1 ec t rodes), and an alignment layer (a 1 i gnment Layer), liquid crystal, liquid filter, space filter, and other components, where the liquid crystal material is usually a combination of a variety of nematic 1 iquid crystal, when the voltage is applied When it is on both sides of the liquid crystal, the liquid crystal starts to invert, and the amount of inversion is controlled by the applied voltage to determine the direction and total amount of light.

Subsequent resources have become a problem for the remaining sticking warp of the ultrasonic device of the patented public apparatus and method of the Republic of China. Injuries must occur, or other methods remain, and the method of discarding a flat-panel display is used as a monitor. In difficulties, such as the problems of its direct diversity and the heavy pollution of human living flat displays, there are special incinerators for human health, stupidity is the main, these types of materials, and the exhaust gas of which must also be made of plastic materials Imagination; Recycling with resources and reutilization.

However, since the process is wet and air-dried, it has no infrared orientation, but the high temperature obviously causes drying time, which is difficult. Make sure to return the range. And the front and back are not easy to operate. The microwave power in the flat-panel display depends on the quality of industrial products such as paper products, wine making, rubber and styling, textile, and thawing applications.

Description of the invention (5) It takes time for the water to overcome the surface tension, which will be sequentially evaporated from the interstitial space, and the microwave will directly act on it. Water vapor can simultaneously open the interstitial space and overflow, and its energy action mode It is very different from the traditional one. It not only improves the drying efficiency, but also raises the value of improving the substrate material. This is a new application not mentioned in the previous literature. Therefore, how to speed up the drying reaction and reduce the process time, the more important problem to be solved is to reduce the damage of drying to the material, so as to increase the recycling value of the recycling flat panel display. Currently, no related patents, especially the processing method of microwaves, have been proposed. Therefore, in view of the fact that the conventional drying method for recycling liquid crystal screens is not perfect, the inventors devoted themselves to research, and after many experiments and improvements, they were able to invent the invention. [Summary of the invention] The present invention is to provide a complete and fast drying with simple production procedures and a small cost, which is conducive to mass production, can be continuously placed in the furnace, fast, safe, noiseless, and cheap And accelerate the subsequent recycling process, so it has the advantages of safety, reliability, low cost, high use value and convenience of the microwave drying process of recycling LCD screens. It is characterized by placing the wet flat display recycling material in a microwave environment and using microwave energy to concentrate on the separation of water, a method that helps to recover materials such as glass substrates.
