Movable Backlight and Liquid Crystal Layer Squeeze for Camera Light Transmittance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing design of electronic devices with liquid crystal displays compromises camera shooting quality due to poor light transmittance in the light-transmitting area, requiring hollowing out of the liquid crystal layer, which affects display and appearance performance.
Innovation Solution
The electronic device incorporates a movable backlight component and a movable block that can be driven to squeeze the liquid crystal layer, increasing light transmittance by thinning the area opposite the camera, allowing more light to pass through without hollowing out the liquid crystal layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the liquid crystal layer is made thinner to increase light transmittance, then camera shooting quality is improved, but display performance deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the liquid crystal layer thickness adjustable rather than fixed. A driving mechanism is introduced that can dynamically change the thickness of the liquid crystal layer in the light-transmitting area based on operational modes. When camera shooting is needed, the layer is compressed to become thinner for better light transmittance; when display is needed, the layer returns to normal thickness for optimal display performance.
2Illumination intensity
If the liquid crystal layer is hollowed out to increase light transmittance, then camera shooting quality is improved, but appearance and display performance deteriorate
Solution Approach 1:
Instead of permanently hollowing out the liquid crystal layer, the patent uses a dynamic compression mechanism that temporarily reduces the layer thickness only when needed for camera shooting. The liquid crystal layer maintains its complete, intact structure at all times, preserving the device's appearance and display performance, while dynamically adjusting thickness to optimize light transmittance during camera operation.
3Illumination intensity
If the liquid crystal layer is hollowed out to increase light transmittance, then camera shooting quality is improved, but display performance deteriorates
Solution Approach 1:
The patent resolves this contradiction by implementing a dynamic system where the liquid crystal layer thickness is adjusted based on operational requirements. During camera shooting mode, the driving mechanism compresses the liquid crystal layer to increase light transmittance. During display mode, the layer returns to its normal thickness to ensure optimal display performance. This dynamic adjustment eliminates the need to permanently compromise display performance through hollowing out.
