Description of the invention α) The present invention relates to a method for treating resources of a liquid crystal display. The method mainly involves breaking an abandoned liquid crystal display panel into a closed furnace and heating it in sections. After the rubbing and de-filming process, the money film layer is separated to form a clean glass sheet. The separated mineral film oxide can be recovered as a colorant additive. The clean glass sheet can be reused after crushing and processing. With the development of the electronics industry, the environmental issues that follow have also caused headaches for the operators and related authorities. Liquid crystal display (Liquid Crysta 1 D is ρ 1 ay hereinafter referred to as LCD) Generally there are TN (Twisted Nematic) liquid crystal display, STN (Super Twisted Nematic) liquid crystal display, TFT (Thin film transistor) liquid crystal display and LTPS (Low Temperature Poly S i 1 ic ο Liquid display "Take a thin film transistor liquid crystal display (τ hin film transistor liquid crystal display) TFT-LCD as an example, its appearance dates back to 1962, the engineer of the RCA laboratory in the United States Paul Wei mer proposed thin film transistor liquid crystal display technology; 1988 Sharp Corporation (Sharp) made the first j 4-inch liquid crystal display panel. Since then, let the computer screen completely slump, from heavy and large to light and thin. Comparing a 15-inch CRT screen with a liquid crystal display, the weight of a liquid crystal display is only about half that of a CRT, and the depth is about one third of that of a CRT. In addition, the yield of TFT-LCD panels has been continuously improved, and the sales volume has been declining. Therefore, it has largely replaced traditional CRT fluorescent lamps. TFT-LCD thin film transistor liquid crystal display mainly includes glass substrate, shirt color filter, polarizing plate, backlight module and driver [C, among which,

Description of the invention (2) The upper and lower glass substrates are used to hold the liquid crystal. The lower glass has a thin gland φTinin film 十 十 TI? Τ Λ -r * »cj. Thin film transistor (TFT), while the upper layer is glass, electric, color filter, the surface of the glass is coated with a layer of poly, polyimide [or ITO film] alignment film (align 11 1 m ), / Function Provides the interface condition that the liquid crystal molecules are uniformly arranged, and the order of the Japanese knives is arranged. The general CRT screen uses high-speed thunder and lightning to strike the fluorescent powder on the silver screen according to the pre-displayed electrons. In order to produce bright light, the county emits daylight, but the liquid crystal display itself can only control the light flow. The display itself does not have the function of emitting light. Therefore, the liquid crystal display must be a pig. L, breadth and shavings plus a back light board (back light, BL) to provide a light source with high brightness and brightness distribution. Finally, with the help of Prism Sheet and diffuser plate, 77 evenly distributes the light to each area to provide a TFT LCD—a bright light 'source. There are also two structural components, Sealant and Spacer. The purpose of the frame adhesive is to make the upper and lower layers of glass in the liquid crystal panel adhere tightly and to block the liquid crystal molecules in the panel from the outside world. Therefore, the frame adhesive, as its name implies, surrounds the panel and limits the liquid crystal molecular frame to the panel. within. The Spacer mainly provides support for the upper and lower glass layers. It must be evenly distributed on the glass substrate. Once the uneven distribution causes some Spacer to gather together, it will hinder the passage of light, and it will not be able to maintain a proper gap between the upper and lower glass. (Gap) 'causes the phenomenon of uneven electric field distribution, which in turn affects the grayscale performance of the liquid crystal. However, because the TFT-LCD contains small molecular structures—night crystals, ordinary recycling methods cannot be used, because liquid crystals and heavy metal emulsions are 'easy to cause pollution' and cannot be recycled for use in the glass industry. , Can only be used in low-level, pollution-free industries, and
