Abstract: As an imaging prevention method for interfering unauthorized imaging of a number of visual images projected on a screen, there is employed a method for projecting infrared light to a viewer/audience direction from at least one or more infrared light projector devices. According to the method, infrared light may be directly incident into an imaging apparatus of a person conducting an unauthorized copying act so as to adversely affect the unauthorized copying.

Abstract: As an imaging prevention method for interfering with the unauthorized imaging and recording of a visual image projected on a screen, there is employed a method for projecting infrared light to a viewer/audience direction from at least one or more infrared light projector means disposed at a rear side of the screen. According to the method, an amount of the infrared light is directed to be incident into an imaging apparatus attempting to record an image from the screen, increasing a pirating prevention effect.

Abstract: A two-layer film carrier for TAB is made from a substrate prepared by forming a copper layer on a polyimide film by additive plating. A photoresist layer is formed on the copper layer, and another photoresist layer on the polyimide film. Both of the photoresist layers are simultaneously exposed to light through a mask applied to each of them to define a desired pattern. The exposed portions of the photoresist layer on the copper layer are subjected to development and postbaking, whereby selected portions of the copper layer are exposed. The exposed portions of the copper layer are additive plated with copper, whereby leads are formed. The exposed portions of the photoresist layer on the polyimide film are subjected to development and postbaking, whereby selected portions of the polyimide film are exposed. The remaining portions of the photoresist layer are removed from the copper layer and the underlying copper layer is etched.
