Transparent Display Panel Dimming for Background Light Contrast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent displays are affected by both internal devices and external background light, leading to poor display effects due to increased background light intensity.
Innovation Solution
A display panel with a dimming part and photosensitive components is designed, where the dimming part overlaps with light transmissive areas and is electrically connected to the photosensitive component, which adjusts the light transmittance based on background light intensity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If transparent display is used to maintain light transmittance, then transparency is improved, but display contrast deteriorates due to background light interference
Solution Approach 1:
The display area is segmented into pixel areas and light transmissive areas, with the dimming part specifically positioned to overlap with light transmissive areas. This segmentation allows different regions to have different light transmittance characteristics, enabling the dimming part to reduce background light interference in specific areas without compromising the overall transparency of the display panel.
Solution Approach 2:
The dimming part's light transmittance is made dynamic through electrical connection to the photosensitive component. The system automatically adjusts the dimming part's light transmittance based on detected background light intensity, transitioning between transparent and dimmed states. This dynamic adjustment resolves the contradiction by adapting light transmittance to environmental conditions rather than maintaining a fixed state.
2Loss of information
If dimming part is added to reduce background light influence, then display contrast is improved, but device complexity increases
Solution Approach 1:
The dimming part is merged with the display panel structure, with its light transmissive area overlapping with the light transmissive areas of the display panel. The photosensitive component is electrically connected to the dimming part, creating an integrated system. This merging approach reduces device complexity by combining multiple functions (display, light transmission, and automatic dimming control) into a unified structure rather than adding separate independent components.
Solution Approach 2:
The photosensitive component enables the system to automatically detect background light intensity and control the dimming part's light transmittance without external intervention. This self-service mechanism eliminates the need for manual control or complex external control systems, reducing overall device complexity while maintaining effective contrast adjustment.
3Adaptability or versatility
If photosensitive component is added to control dimming part, then adaptability to background light is improved, but manufacturing complexity increases
Solution Approach 1:
The system changes the light transmittance parameter of the dimming part based on background light conditions detected by the photosensitive component. By electrically controlling the optical properties of the dimming part, the system achieves adaptability to varying background light environments. This parameter-based control approach is more manufacturable than mechanical or optical mechanisms, as it可以利用 standard electrical control techniques and materials.
