Domestic display the status of the industry is growing day by day. However, in large part due to lack of core technology and core materials are imported from abroad and free continuing cost pressures in the display industry as a cost savings for the new method is required. Today, large open world markets and the memory of electronic products in Korea, cpu and display markets such as semiconductor chip market is strong. Semiconductor chips, circuit line widths of several tens nm is very high enough density, it was part of a family of very high performance can be seen. Visible to the eye, while the display market to implement a display device, so if the pixel size of 100 microns or more are mostly very low density, so the relatively low performance belongs to the product family. These micro (μ) low-grade disposable electronic products / devices manufactured by the equipment, the printing process, a study using the technique began to receive the spotlight. Electronic industry, printing technology, innovation and competitiveness through technology development efforts underway in the process was accepted as a suitable technique such printed electronics has been created, a new concept, the technology and electronic components and circuits efforts to apply to the creation is increasing. Conventional method of forming the conductive pattern, the screen printing method was mainly used. Screen printing of the mask by the limits of the difficult to high accurate pattern formation, Roll-to-Roll printing a hard high-speed printing and mass production is difficult. The screen printing of the issue due to the ubiquitous that form the basis of a large consuming RFID tags and wireless sensor, and roll-to-roll printing method which will produces it from these technologies. According to these forecast, the developed countries has already invested to the research and development. Roll-to-Roll printing by the electronic device that was produced using traditional printing techniques with Precise control of the most recent technology and processing technology is applied to the fine-line printing is very cost-effective equipment that can be implemented is evaluated. In order to function as electronic devices, fine-line printing of dozens of level is required instead of traditional dot. And should not break the line at all. So in accordance with these ink transfer conditions should be established. In order to solve it right now, which is being developed to Roll-to-Roll-patterning process of method. That is due to Roll-to-Roll that is a continuous printing process. The variety of roll-to-roll printing used in many ways is a gravure offset method. The current domestic situation, For PDP with Photosensitive Ag paste prepared electrodes and according to gravure offset method, electrode pattern has been manufactured. Ag paste for PDP has been developed by SSCP, Cheil Industries, Ildong chemistry, Doosan electronics, and various companies. None Solvent gravure offset development of Ag paste is largely needed, Maximizing productivity through process improvement, Symptoms of Swelling of silicone rubber to minimize the number of continuous printing is 500 times or more is required. Therefore domestic production of raw materials and Ag paste as the long-run eco-printable paste manufacturing technology is urgently required. In this study, depending on type of Resin, solvents, additives, used in Ag paste for gravure off set that in order to evaluate dispersion characteristics and condensation structure for measuring rheology and based on the results of rheologycal, offset gravure printability was examined. Depending on the type of solvent printing reviewing competence, Blanket for a long time to absorb a certain amount of Glycol type paste showed the most outstanding features in continuous printing. Based on the type of resin acryl type of reviewing printability paste and paste the pattern of epoxy type Sharpess was excellent. According to the reviewing results, that Rheology properties of Ag paste printing characteristics, immediately after printing, the stored elastic modulus (G') has the highest acryl type paste thickness was highest and storage modulus (G') is lowered to lower the print thickness was know . As a result, PDP Address and Bus as well as for the electrodes, TFT, Flexible PCB Board, Touch panel display, Flexible display, solar cell, etc. can take advantage of the electrode pattern.
