When we look around our home, or car for that matter, it seems that almost every electronic device has an LCD display of some description, with screen sizes ranging from miniature to over 50 inches in the case of LCD televisions.
In the vast majority of cases, every pixel in the screen is active. The rows and columns of the pixel matrix are activated using transparent indium tin oxide (ITO) conductive paths. As part of the process in the production of TFT displays, a conductive connection must be established between the rows and columns of the matrix – an intentional short circuit, as it were. However, at a later stage in the production process, this step must be carefully undone. The power and precision of Rofin’s new PowerLine SL 8 IC laser makes it the ideal tool for this intricate task.
