摘要:
A light control layer includes alternating transmissive and absorptive regions, along one or two dimensions. The light control layer may be substantially transparent, or have high transmission, for light incident at or near a normal angle to its surface, while absorbing light incident at angles away from normal. The height of the absorptive region, defined orthogonal to the local display surface, may be much greater than the width of the absorptive region resulting in a high aspect ratio structure. The width of the absorptive region may be relatively thin compared to the width of a pixel in a display. The light control layer may be applied to a display or incorporated into a display. The light control layer may be part of a film stack including other functional layers that cooperatively provide desirable optical properties.
