Abstract
The production of liquid crystal displays (LCDS) on plastic substrates is desirable over glass substrates so that the finished product is thinner, lighter, and more robust. Plastic substrates can enable the use of new and different processing techniques which are not possible on glass such as roll-to-roll processing. This invention discusses an advancement which is laser cutting a plastic substrate and display layer. One aspect of the invention is laser cutting and welding together two or more plastic substrates and LCD layer therebetween from a larger sheet or roll of plastic LCDs.
