Abstract : An improvement for a large screen display eliminates the gap/grid line which is otherwise present between abutted display modules. Each of the display modules has a light-emanating/reflecting display surface which provides a visual indication of the information content on a problem of a visual display for the large screen. A diverging strip is superimposed over each gap/grid line and at least a portion of the butting light-radiating display surfaces so that light is diverged from the abutted light-radiating surfaces to optically mask the gap/grid line and present a continuous uniterrupted display across the surface of the large screen display. The diverging strip can be tilted hollow fiber microchannels, tilted optical fibers or tilted plastic fibers inclined or fan-shaped at about a 10 deg -15 deg angle so that the gap/grip lines are optically masked. Optionally, a diverger panel as big as the display module is superimposed over each module extending over the gap/grid line for diverging the light projected from the abutted light radiating panels, thereby optically masking each gap/grid line. A linear face plate is mounted on the strip to improve the viewing angle.
