Embodiment

[0082] Various embodiments will be further clarified by the following non-limiting examples.

[0083] Figure 4 An anode / glass substrate / cathode stack or assembly 100 for thermal polarization of a glass substrate 110 in this embodiment is depicted. The glass substrate in this example had a composition as generally disclosed in WO2017 / 070066, which is hereby incorporated by reference in its entirety.

[0084] as in Figure 4 As shown in , a stainless steel metal electrode 120 in contact with a stainless steel gauge block 130 acts as an anode and contacts the major surface 112 of the glass substrate 110 to provide an anode surface 140 of the glass substrate 110 . The gauge block 130 has a flatness and surface area for intimate contact with the anode surface 140 . A piece of graphite 150 sitting on a stainless steel base plate 160 acts as a cathode and contacts the opposite side of the glass substrate to form a cathode surface 170 of the glass substrate. The surface area of...

Abstract

A light guide plate that includes a glass substrate including an edge surface and at least two major surfaces defining a thickness and an edge surface, the edge surface configured to receive light from a light source and the glass substrate configured to distribute the light from the light source, wherein the glass substrate comprises an alkali-containing bulk and an alkali-depleted surface layer, the alkali-depleted surface layer comprising about 0.5 atomic% alkali or less. Display products and methods of processing a glass substrate for use as a light guide plate are also provided.
