Abstract
A display for presenting a stereoscopic image includes multiple layers of image forming devices configured to provide the stereoscopic image and an etched substrate configured to diffuse light projected through or from the multiple layers of image forming devices. The etched substrate is laminated or bonded to a front surface of the multiple layers of image forming devices.

A display for presenting a stereoscopic image, comprising:
- multiple layers of image forming devices configured to provide the stereoscopic image;
- an etched substrate configured to diffuse light projected through or from the multiple layers of image forming devices, wherein an integrated bidirectional reflectance distribution function for the etched substrate is between 0.1 and 0.2 at a −1° to 1° angle of incidence of a light source for specular reflectance, is between 1.0 and 1.5 at a −1° to −10° and a 1° to 10° angle of incidence of the light source for haze reflectance, and is between 0.9 and 1.4 at angles less than −10° and greater than 10° angle of incidence of the light source for diffuse reflectance;
- wherein the etched substrate is laminated or bonded to a front surface of the multiple layers of image forming devices.
A method for forming a display for presenting a stereoscopic image, comprising:
- forming multiple layers of image forming devices configured to provide the stereoscopic image;
- and
- dry film laminating an etched substrate to a front surface of the multiple layers of image forming devices using a method comprising:
- disposing a pressure-sensitive adhesive layer between a surface of the etched substrate and the front surface of the multiple layers of image forming devices;
- disposing the etched substrate, pressure-sensitive adhesive layer, and multiple layers of image forming devices within a vacuum chamber;
- evacuating the vacuum chamber;
- and
- applying pressure to at least one of the etched substrate and the multiple layers of image forming devices.
