Optical Systems Having Light Sources with Power Saving Modes - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18156309 Titled 'Optical Systems Having Light Sources with Power Saving Modes'
Simplified Explanation
This abstract describes a display technology that uses illumination optics, a spatial modulator, and a waveguide to produce image light. The display includes both low power and high power light sources, which can be activated separately depending on the image data being displayed. When virtual objects in the image data are only present in the peripheral region of the viewer's field of view, the low power light sources are used to conserve energy. Control circuitry adjusts between these two states based on the image data.
Original Abstract Submitted
A display may include illumination optics, a spatial modulator, and a waveguide. The illumination optics may produce illumination that is modulated by the spatial modulator to produce image light. The waveguide may direct the image light towards an eye box. The illumination optics may include light source sets that produce the illumination. Each set may include a low power light source and a high power light source. In a first state, the high and low power light sources may be active. In a second state, the low power light sources may be active. Control circuitry may adjust between the first and second states based on image data. The second state may be used when virtual objects in the image data are confined to a peripheral region of the field of view of the eye box.
