Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with integrated liquid crystal panels and cameras face challenges in capturing clear images due to the overlap of the camera with the incident light control area, which affects light transmission and control, leading to suboptimal image quality.
Innovation Solution
The electronic device incorporates a liquid crystal panel with a display area, an incident light control area, and a peripheral area, where the camera overlaps the incident light control area, utilizing a lead line connected to control electrodes to manage light transmission effectively, allowing light to pass through the incident light control area and be incident on the camera.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera overlaps the incident light control area of the liquid crystal panel, then the device can capture images through the display surface, but the image quality deteriorates due to insufficient light transmission control
Solution Approach 1:
The liquid crystal panel is divided into distinct functional areas: a display area with pixel electrodes for visual output, and a separate incident light control area with control electrodes for camera light transmission. This segmentation allows independent optimization of each area's performance characteristics.
Solution Approach 2:
Different regions of the liquid crystal panel are assigned different electrode configurations and optical properties. The incident light control area uses control electrodes with specific shapes and arrangements optimized for light transmission control, while the display area uses pixel electrodes optimized for image display.
2Ease of operation
If the incident light control area uses control electrodes for light transmission, then light can be controlled to reach the camera, but the precision of light transmittance control is insufficient leading to suboptimal image quality
Solution Approach 1:
The control electrodes are designed to dynamically adjust light transmission by applying different voltages. The liquid crystal molecules respond to voltage changes by rotating, thereby dynamically controlling the amount of light transmitted through the incident light control area to the camera.
Solution Approach 2:
The system controls light transmission by changing electrical parameters (voltage applied to control electrodes) which in turn changes the optical parameters (light transmittance) of the liquid crystal layer. This allows precise control of light intensity reaching the camera.
3Adaptability or versatility
If the camera is positioned to overlap the incident light control area, then close-range photography is enabled, but image quality suffers due to inadequate light control
Solution Approach 1:
The incident light control area is prepared in advance with specifically designed control electrodes and liquid crystal alignment structures. This preliminary configuration enables precise light control when the camera captures close-range images, ensuring high image quality from the outset.
