SWITCHED EMISSIVE TRANSPARENT DISPLAY WITH CONTROLLABLE PER-PIXEL OPACITY

摘要

A display system adapted to use rapid switching techniques to switch between displaying content and displaying a mask for that content so as to provide per-pixel opacity control. The display system may employ rapid synchronized switching of both a non-emissive, transparent display and a transparent backlight. In a first state, the display is operated to display content with the backlight acting as a scattering luminous backlight. In the other or second state, the display is operated to display one or more masks (for some or all objects or items of the content displayed in the first state) with the backlight functioning as a clear and unlit backlight. The display system is capable of producing opaque emissive content on a transparent field to provide a novel display and/or for use in compact spatial augmented reality applications.

主权项

1. A display system, comprising:
a display element including a non-emissive display panel; a backlight assembly; and a display controller operable to switch operations of the display element between first and second operating states and to switch operations of the backlight assembly between first and second operating states, wherein the non-emissive display panel displays content in the first operating state of the display element and displays a mask for the content in the second operating state of the display element, and wherein the backlight assembly is luminous in the first operating state of the backlight assembly to direct light onto a surface of the non-emissive display panel and is transparent in the second operating state of the backlight assembly.
