Problems solved by technology

[0006] Unfortunately, transparent displays may still have various defects, such as poor light transmission and / or reflection, which can greatly limit the contrast ratio of the display
For example, commercially available transparent displays can only provide about 15% transmission, and even worse performance for reflective mode

Abstract

Disclosed herein are laminate structures comprising a light guide plate including a first glass sheet, wherein the first glass sheet comprises from about 50 mol% to about 90 mol% SiO2, from about 0 mol% to about 15 mol% Al2O3, and about 0 mol% to about 19 mol% RxO, wherein x is 1 and R is chosen from Zn, Mg, Ca, Sr, or Ba, or wherein x is 2 and R is chosen from Li, Na, K, Rb, or Cs, and wherein the concentration of Fe is less than about 50 ppm

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119 to U.S. Provisional Application Serial No. 62 / 169910, filed June 02, 2015, which application is based upon and is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to laminated structures, and more particularly, to automotive glazing that includes light guides. technical background [0004] In recent years, the automotive industry has begun to incorporate glass as an exterior and / or interior surface of a vehicle in order to enhance the aesthetics of the vehicle and / or increase the visibility of the exterior environment to passengers. For example, glass laminates can be used as functional or decorative components such as windows, canopies, mirrors, and exterior or interior panels. Glass laminates are also attractive as automotive glazing because of the improved fracture safety and / or impact resistance that can ...
