Color filters are produced using semiconductor production techniques although problems with low yield remain to be addressed. This study presents a new means of selective removal using excimer irradiation, chemical etching, or electrochemical machining on the fifth generation TFT LCDs. The selective removal of microstructure layers from the color filter surface of an optoelectronic flat panel display, as well as complete removal of the iTO thin-films, RGB layer, or resin black matrix (BM) layer from the substrate is possible. individual defective film layers can be removed, or all films down to the Cr layer or bare glass can be completely eliminated. Experimental results demonstrate that defective iTO thin-films, RGB layers, or the resin BM layer can now be recycled with a great precision. When the iTO or RGB layer proves difficult to remove, excimer light can be used to help with removal. During this recycling process, the use of 225 nm excimer irradiation before chemical etching, or electrochemical machining, makes removal of stubborn film residues easy, effectively improving the quality of recycled color filters and reducing fabrication cost.

A reuse fabrication module using micro electrochemistry (MECM) with a round-ball tool to remove the defective in2O3 SnO2 thin film from the surfaces of digital paper display was *** etching effect improves that the number of the round-balls decreases for promoting the concentration of electric power and increasing discharge *** a small size of the round-ball tool takes less time for the same amount of in2O3 SnO 2 layer removal since the effect of MECM is easily developed for supplying of sufficient electrochemical power.A higher feed rate of the poly ethylene terephthalate (PET) diaphragm combines with enough electric power to drive fast etching rate.A pulsed direct current can improve the effect of dreg discharge and is advantageous to couple this current with the fast feed rate of the *** the ultra-precise etching of in2O 3 SnO2,the optoelectronic semiconductor industry can effectively reuse the defective products,reducing production *** precision etching process is of high efficiency and requires only a short period of time to remove the in2O3 SnO2 nanostructures.

A new effective tool design of three-rank form of electroremoval was present using a precision recycle system offering faster performance in removing the indium-tin-oxide(iTO) thin-films on color filter surface of displays. Higher electric power is not required since the three-rank form tool is adopted as a feeding mode to reduce the response area. The low yield of iTO persists throughout the entire semiconductor production process. By establishing a recycle process of ultra-precise removal of the thin-film nanostructure, defective products in the optoelectronic semiconductors industry can be effectively recycled, decreasing both production costs and pollution. A 5th generation TFT-LCD was used. The design features of the removal processes for the thin-films and the tool design of three-rank form were of major interest. For the precision removal processes, a pulsed current can improve the effect of dreg discharge and contributes to the achievement of a fast workpiece (displays' color filter) feed rate, but raises the current rating. High flow velocity of the electrolyte with a high rotational speed of the tool electrodes elevates the iTO removal effect. A displays' color filter with a fast feed rate is combined with enough electric power to provide highly effective removal. A small thickness of the rank and a small arc angle of the negative-electrode correspond to a higher removal rate for iTO-film. An effective three-rank form negative-electrode provides larger discharge mobility and better removal effect. it only needs a short period of time to remove the iTO easily and cleanly.

To describe a case of probable relapsing autoimmune hepa.itis associated with vaccination against hepa.itis A virus （HAV）. A case report and review of literature were written concerning autoimmune hepa.itis in association with hepa.itis A and other hepatotropic viruses. Soon a^er the administration of formalin-inactivated hepa.itis A vaccine, a man who had recently recovered from an uncharacterized but self-limiting hepa.itic illness, experienced a severe deterioration （AST 1687 U/L, iNR 1.4）. Anti-nuclear antibodies were detectable, and liver biopsy was compa.ible with autoimmune hepa.itis. The observation supports the role of HAV as a trigger of autoimmune hepa.itis. Studies in helper T-cell activity and antibody expression against hepa.ic proteins in the context of hepa.itis A infection are summarized, and the concept of molecular mimicry with regard to other forms of viral hepa.itis and autoimmunity is briefly explored.
