Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies, such as LCD and OLED, struggle to provide a realistic viewing experience for dazzling images like the Sun or explosions due to uniform brightness across the screen, making it difficult for users to distinguish between bright and surrounding images.
Innovation Solution
An electronic glasses apparatus that receives a synchronous video signal from a display device and drives pixel cells to emit light based on the parameters of a first area with a high grey scale, enhancing light intensity differences by selectively illuminating corresponding areas with white or matching colors, while keeping other areas dark.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If uniform backlight or self-emitting light source is used in LCD or OLED display, then the display structure is simple and manufacturing is easy, but the brightness of dazzling images becomes similar to surrounding images, reducing visual realism
Solution Approach 1:
The display screen is divided into multiple independently controllable light-emitting regions (first area and second area). The first area corresponds to dazzling image regions and the second area corresponds to surrounding regions. This segmentation allows different brightness levels to be applied to different regions, creating realistic visual effects while maintaining a relatively simple overall display structure.
Solution Approach 2:
Different regions of the display screen are assigned different light emission properties. The first area (dazzling image region) is configured to emit light with higher intensity, while the second area (surrounding region) emits light with lower intensity. This local differentiation of light emission quality enhances visual realism without requiring complete restructuring of the entire display system.
2Illumination intensity
If all pixel cells are driven to emit light simultaneously, then the image display is complete, but the light intensity difference between dazzling images and surrounding images is reduced
Solution Approach 1:
The pixel cells are segmented into two groups: those in the first area and those in the second area. The control circuit drives pixel cells in the first area to emit light when dazzling images are detected, while pixel cells in the second area remain dark or emit minimal light. This segmentation enables significant light intensity differentiation while still displaying the complete image content.
Solution Approach 2:
The display system periodically detects dazzling image regions in the video signal and dynamically adjusts which pixel cells emit light. This periodic detection and selective activation creates temporal variation in light emission, enhancing the perception of dazzling images while maintaining overall image completeness.
3Illumination intensity
If selective light emission is implemented to enhance dazzling image effect, then visual realism is improved, but the control system complexity increases
Solution Approach 1:
The control circuit creates a simplified copy or map of the video signal's brightness distribution to identify dazzling image regions. Instead of complex analysis of the entire video content, the system uses brightness threshold detection to generate a control pattern that mirrors the luminance characteristics of the original signal, enabling selective light emission with relatively simple control logic.
Solution Approach 2:
The system replaces complex mechanical or optical modulation mechanisms with electronic control of light-emitting diodes. By using electronic signal processing to detect dazzling regions and control LED activation, the system achieves enhanced visual realism through software-based control rather than complex hardware mechanisms, thereby limiting the increase in overall system complexity.
