Display Projecting Reflections Onto Geometric Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display systems fail to accurately reproduce the dynamic effects of light reflections and diffraction, such as flickering and scintillations, which are essential for realistic representation of objects, especially when the observer's position or light source changes.
Innovation Solution
A display device comprising a screen and a projector connected to a digital image broadcasting system, where the projector projects a second image onto a reflecting surface with geometric patterns, allowing for optical superimposition of reflections onto the screen image, creating a realistic and dynamic representation of light reflections and flickers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional display screens are used to show images, then image quality and detail can be displayed, but the dynamic effects of light reflections and flickers cannot be reproduced
Solution Approach 1:
The display system is segmented into two independent components: a conventional display screen for showing the base image, and a separate projector system for adding reflection and flicker effects. This allows each component to optimize its function without compromise.
Solution Approach 2:
The patent combines two different display technologies (conventional screen and projector) into a single integrated system that produces a unified visual output with enhanced realism, merging the strengths of both approaches.
2Device complexity
If a single display means is used for both conventional images and reflection effects, then device simplicity is maintained, but the reflection dynamics are limited by the screen's capabilities
Solution Approach 1:
The display function is divided into two separate subsystems: the original display screen handling static or low-dynamic content, and an additional projector subsystem dedicated to generating high-dynamic reflection and flicker effects.
Solution Approach 2:
The patent adds a new dimension to the display system by introducing a second projection layer that operates independently, enabling dynamic light effects that transcend the limitations of the original screen technology.
3Measurement precision
If the reflecting surface has geometric patterns for realistic reflections, then light ray reflection accuracy improves, but the screen's original image quality may be compromised
Solution Approach 1:
The system separates the image display function (handled by the conventional screen with its optimized pixel structure) from the reflection effect function (handled by the projector with geometric pattern reflection), allowing both to maintain their respective quality standards.
Solution Approach 2:
The projector acts as an intermediary that adds reflection effects without directly modifying the screen's image output, allowing the screen to maintain its original image quality while the projector contributes the geometric pattern-based realistic reflections.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables high-dynamic light performance with realistic rendering of reflections and flickers, independent of the screen's capabilities, providing a more immersive and accurate visual simulation of physical phenomena.
Implementation Method 1
projecting a second image onto a reflecting surface in a predominantly specular reflection mode, said reflecting surface having one or more raised geometric patterns so that incident light rays are reflected in variable directions
Implementation Method 2
means for optically superimposing the screen and the reflecting surface such that for an observer using the display device, a second image projected on the reflecting surface is superimposed on a first image displayed on the screen

AI summary
The device (100) for displaying images comprises a viewing terminal (20) a screen of which (21) is functionally connected to a system for disseminating digital images (24) in order to display a first image (50). Furthermore, a projector (23) is connected to the system for disseminating digital images (24) in order to project a second image (52) onto a reflective surface of a medium (22), the reflective surface comprising three-dimensional geometric features so that incident light rays are reflected in variable directions and comprises means for optically superposing the screen (21) and the reflective surface in order to superpose the second image on the first image (50) and form an image (59) of the object comprising reflections or scintillations. The method allows the reflections and/or scintillations of an image to be simulated.
