Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air ionization imaging systems face challenges in increasing the number of pixels on the display screen due to the limited pulse power output by the light source, making it difficult to enhance the sharpness and resolution of the images.
Innovation Solution
The air ionization display device employs a pulse-light-source module that generates multiple synchronous pulse light beams, which are then adjusted and converged by a light field control module to ionize air and form a holographic real image, effectively increasing the number of converged points and pixels on the display screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the pulse power output by the light source is increased to increase the number of pixels on the display screen, then the pixels of the display screen can be increased, but it is difficult to greatly increase the pulse power output by the light source in the related art
Solution Approach 1:
The patent divides a single high-power pulse light source into multiple lower-power pulse light sources. Each light source generates pulse light beams that are independently controlled and then combined through a beam combiner to form the final holographic image. This segmentation allows the system to achieve the equivalent of high pixel count without requiring a single extremely high-power light source, thus resolving the contradiction between increasing pixels and the difficulty of greatly increasing pulse power output.
2Manufacturing precision
If a lens is used to converge light beams to ionize air at a focal point, then air ionization imaging can be achieved, but the number of converged points is limited by the pulse power
Solution Approach 1:
The patent employs multiple pulse light sources instead of a single light source to create multiple convergence points in the air. Each light source contributes to forming specific portions of the holographic image, allowing the system to generate a larger number of converged points simultaneously. This segmentation approach directly addresses the limitation of having a restricted number of converged points when using traditional single-source systems.
Solution Approach 2:
The patent transitions from a single-point convergence model to a multi-point convergence model by introducing multiple light sources. This dimensional expansion in the light source configuration enables the system to create multiple focal points in the air simultaneously, each contributing to different regions of the holographic image, thereby increasing the overall number of converged points and improving image resolution.
