Problems solved by technology

This misalignment causes undesired blocking of portions of the apertures, causing reduced light throughput through the apertured layer
In addition, poor alignment can result in portions of the reflective layer not being fully covered, causing unwanted reflections that reduce the contrast ratio of the display

Embodiment Construction

[0037] Some displays include an aperture layer that restricts the emission of light from the backlight to a set of desired emission locations. Such voided layers may include light absorbing layers and light reflecting layers. Apertures are formed through each layer to allow the passage of light at desired locations. The present invention relates to voided layers comprising voids self-aligned by multiple thin film layers for use in displays. This application also relates to methods for producing such voided layers.

[0038] The methods disclosed herein for forming voided layers prevent misalignment and result in light absorbing and light reflecting layers with substantially aligned voids. In some implementations, the method includes providing a substrate, providing a light reflecting layer on the substrate, and providing a light absorbing layer on the light reflecting layer. A first set of openings is then formed in the light absorbing layer, and a second set of openings is ...

Abstract

A display for imaging is disclosed. The display for imaging includes an aperture layer and a set of light modulators. The aperture layer includes a light absorbing layer disposed over a light reflecting layer, each layer having a set of apertures defined therein. The light absorbing layer includes light absorbing material suspended in a photosensitive resin. The set of light modulators are used for modulating light passing through the apertures defined in the aperture layer.
