LCD LOCA Full Lamination Process And Improvement

Today, users of smart phones have made more and more critical requirements: thinner,lighter, better display. A whole new display manufacturing technology----full lamination,to achieve a good effect of these improvements.Previous generation of touch-screen display is structured to protect the glass+touchscreen+LCD display, three-tier structure needed twice ordered OCA optically adhesivebonding, or even frame affixed way fit. With the development of the times, this kind oftouch-screen display also highlights the shortcomings out: the high cost of materials,production processes long, thick, heavy, and the display is not so good.LOCA fulllamination is a new lamination process, the glass structure with a single solution of In-Cell,On-Cell, OGS technology, production of the touch-screen display perfectly solves theseproblems. Because only need to use a single LOCA liquid glue laminated glass once,saving material costs, simplifying the production process, making the productsignificantly thinner lighter, enhanced transmittance, showing significant improvement.Full lamination technology to produce smart phones, giving users a better experience, arefreshing feeling.LOCA full lamination as a whole posted a new lamination technology, currently existin the domestic industry has been high technological requirements, yield management andcontrol difficult. If you can master LOCA full lamination quality improvement methods,the LCD manufacturing warlords dispute today, it is equivalent to occupy the leadingposition in the industry.LOCA full lamination processes typical difficulty is lack of excess glue and glue.This article analyzes the causes excess glue and glue lack of the defect, and the improvedprocess approach. The results show that the improved technology can significantly reducethe excess glue, glue lack defects.
