Abstract:
A smart glass display includes a first glass layer, a second glass layer, a display layer, an auto-shading layer and a control module. The display layer is disposed between the first glass layer and the second glass layer and includes an array of light emitting diodes and at least one ambient light sensor. The at least one ambient light sensor is configured to detect a level of ambient light at the display layer. The auto-shading layer includes suspended particle devices each of which configured to selectively provide different levels of transparency. The control module is configured to, based on an output of the at least one ambient light sensor, adjust a transparency level of at least a portion of the auto-shading layer.
