Infrared OLED Integration for Iris Camera Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Iris cameras in electronic devices require supplementary lighting, which often necessitates a hole in the device, compromising its appearance.
Innovation Solution
Integration of an infrared organic light-emitting diode (OLED) within the OLED display screen to provide supplementary lighting for the iris camera, eliminating the need for an external lighting source and maintaining the device's aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If an arranged supplementary lighting lamp is used for the iris camera, then the lighting requirement is met, but a hole must be defined in the device which influences the appearance
Solution Approach 1:
The infrared OLED is integrated directly into the OLED display screen structure, merging the supplementary lighting function with the existing display component. This eliminates the need for a separate lighting lamp and the associated hole in the device housing, thereby maintaining the appearance while providing necessary illumination for the iris camera.
Solution Approach 2:
The OLED display screen serves dual functions: it acts as both the display interface and the supplementary lighting source for the iris camera. By making the display screen multi-functional, the patent eliminates the need for dedicated external lighting components, thus preserving the device's aesthetic appearance.
2Illumination intensity
If an external supplementary lighting lamp is arranged, then the iris camera lighting requirement is satisfied, but additional volume is occupied outside the OLED display screen
Solution Approach 1:
The infrared OLED is nested within the existing OLED display screen structure, utilizing the same physical space and component layout. This nesting approach allows the supplementary lighting function to be housed within the device's existing volume without requiring additional external space.
Solution Approach 2:
By combining the supplementary lighting function with the existing OLED display screen, the patent eliminates the need for separate external lighting components. The integrated infrared OLED shares the same mounting space and structural envelope as the display screen, thereby avoiding additional volume occupation.
3Illumination intensity
If a hole is defined in the device for the supplementary lighting lamp, then the lighting function is achieved, but the attractiveness of the appearance is further influenced
Solution Approach 1:
The patent merges the supplementary lighting function with the existing OLED display screen, eliminating the need for a separate hole in the device housing. The infrared OLED is integrated into the same structural envelope as the display, thereby maintaining the continuous surface and aesthetic appearance of the device.
Solution Approach 2:
The patent extracts the supplementary lighting function from a separate external component and integrates it into the existing display screen structure. This extraction and integration approach eliminates the need for additional holes or openings in the device housing, thereby preserving the appearance attractiveness.
