Solution Overview
Problem
Existing three-dimensional display techniques, such as light field display, face challenges with image crosstalk due to interference from directional light sources.
Innovation Solution
An electronic device with a display panel and a light source module featuring alternately arranged first and second groups of light-emitting units, which alternately emit light to each display pixel, reducing image crosstalk and enhancing stereoscopic display effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a directional light source is used to achieve light field display, then the stereoscopic display effect is improved, but light from different directions interferes with each other causing image crosstalk
Solution Approach 1:
The light source module is segmented into multiple groups of light-emitting units (first group, second group, etc.) that are independently controllable. Each group emits light in specific directions, allowing the system to selectively activate only the light-emitting units needed for the current display frame, thereby preventing interference from other directions and eliminating image crosstalk while maintaining stereoscopic display quality.
Solution Approach 2:
The patent implements periodic action by alternately activating different groups of light-emitting units in a time-division multiplexing manner. The first group emits light during one time period, then the second group emits light during the next time period, and so on. This periodic activation ensures that light from different directions does not interfere simultaneously, resolving the image crosstalk issue while preserving the stereoscopic effect.
2Area of stationary object
If multiple light-emitting units emit light simultaneously from different directions, then the light field display coverage is improved, but light interference causes image crosstalk
Solution Approach 1:
The patent applies periodic action by dividing the display into multiple time periods, where different groups of light-emitting units are activated alternately. During each time period, only one group emits light, ensuring full display coverage is achieved over time without simultaneous light interference that would cause image crosstalk.
Solution Approach 2:
The light source module is divided into multiple independently controllable groups of light-emitting units. Each group is responsible for specific viewing angles or display regions, allowing the system to maintain comprehensive display coverage while preventing cross-interference between different light paths through selective activation.
