Abstract
At least a portion of a polarizing layer in the display screen is omitted or removed to temporarily disable image generation but an equivalent polarizing layer is used as a replacement or as a substitute for enabling the display of images on the screen. For instance, the omitted or removed polarizing layer can be replaced in situ or a remote polarizing layer can be substituted through which the images on the display can be seen. The selective reassembly of the display can be used for purposes of security or promotion.
