Light Shutter Panel Incident Light Control for Camera Display Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with integrated cameras and liquid crystal panels face challenges in capturing clear images due to the need for both display and camera functionality on the same surface, which complicates light management and image quality.
Innovation Solution
The electronic device incorporates a light shutter panel with an incident light control area, including a first annular light-shielding area, a circular incident light control area, and multiple annular incident light control areas, which work in conjunction with an optical member and an imaging device to control light transmission and improve image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera and liquid crystal panel are positioned on the same surface side, then the electronic device can capture images and display information simultaneously, but light management becomes complicated and image quality deteriorates
Solution Approach 1:
The liquid crystal panel is divided into a display area and a non-display area (incident light control area). The non-display area contains light-shielding portions and openings that segment the light path, allowing the camera to receive light from specific directions while the display area maintains normal display functionality. This segmentation enables both camera and display to coexist on the same surface without interfering with each other's performance.
2Measurement precision
If the liquid crystal panel is made transparent for camera light reception, then image capture is improved, but display functionality is compromised
Solution Approach 1:
Different areas of the liquid crystal panel have different optical properties. The display area maintains its light-shielding characteristics for normal display operation, while the incident light control area contains light-shielding portions and openings that allow selective light transmission for camera capture. This local differentiation of optical properties enables the panel to serve both display and camera functions effectively.
3Manufacturing precision
If light-shielding portions are added to control incident light, then image quality improves, but device complexity increases
Solution Approach 1:
The light-shielding portions are integrated into the liquid crystal panel structure itself, merging the light control function with the display panel. The openings and light-shielding portions are formed as part of the panel's layered structure, combining multiple functions (display, light shielding, light transmission) into a single integrated component rather than adding separate external elements.
