Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passive electronic displays, which modulate light provided by another source, face limitations in practical applications due to their inability to emit light, restricting their use in various contexts.
Innovation Solution
A multiview display is implemented using an array of light valves with repeating color sub-pixels and an array of multibeam emitters offset from each other, providing directional light beams to mitigate color fringing and enhance image quality.

1Use of energy by stationary object
If passive displays modulate light from another source, then power consumption is reduced, but the ability to emit light is lost
Solution Approach 1:
The patent combines active light-emitting elements (multibeam emitters) with passive light-modulating elements (light valves) into a single integrated display system. The multibeam emitters provide directional light beams while the light valves modulate these beams to form images, merging the advantages of both active and passive display technologies.
Solution Approach 2:
The display is segmented into two functional arrays: multibeam emitters that generate directional light beams and light valves that modulate these beams. This segmentation allows each component to specialize in its optimal function while working together to achieve both light emission and modulation capabilities.
2Object-affected harmful factors
If multibeam emitters are offset from light valves, then color fringing is reduced, but device complexity increases
Solution Approach 1:
The multibeam emitter array is deliberately offset asymmetrically relative to the light valve array. This asymmetric positioning ensures that light beams of different colors from different emitters converge at the correct locations on the light valves, preventing color fringing while maintaining a manageable structural configuration.
Solution Approach 2:
Each multibeam emitter is positioned with specific local quality characteristics - offset by precise distances from corresponding light valves - to optimize color alignment. This localized positioning strategy reduces color fringing at each pixel location without requiring complex global restructuring of the entire display system.

Function Achieved in This Case
The multiview display effectively reduces color fringing and improves image quality by ensuring even overlap of directional light beams of different colors, thereby enhancing the display's ability to present clear and vibrant multiview images.

AI summary
A multiview display and a method of multiview display operation employ an array of light valves having a repeating plurality of color sub-pixels and an array of multibeam emitters providing directional light beams. The array of light valves having the repeating plurality of color sub-pixels is configured to modulate the directional light beams as color pixels of views of a multiview image. A first multibeam emitter and a second multibeam emitter of the multibeam emitter array are offset from one another with respect to the array of light valves. The offset is configured to direct to a color pixel of the multiview image a modulated directional light beam from each of the first multibeam emitter and the second multibeam emitter having an equivalent angular direction relative to one another. The equivalent angular direction may mitigate color fringing within the color pixel.
