Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current EL display panels require an additional camera for image-taking functionality, increasing production costs due to the expense of the camera.
Innovation Solution
Integration of image sensing units within each sub-pixel unit, connected to a drive module that controls both image sensing and sub-pixel units, allowing the display panel to take images and display them without the need for a separate camera.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an additional camera is arranged on the display device to implement image-taking function, then the image-taking capability is improved, but the production cost increases due to the expensive camera component
Solution Approach 1:
The patent combines the image sensing function with the display panel by integrating image sensing units within the pixel units. Each pixel unit contains both sub-pixel units for display and image sensing units for capturing images, merging two separate functions (display and image capture) into a single integrated component, thereby eliminating the need for a separate camera and reducing production costs
Solution Approach 2:
The display panel is designed to perform multiple functions: it can display images through sub-pixel units and simultaneously capture images through image sensing units. This multi-functional design allows the display panel to replace the traditional separate camera component, achieving versatility while reducing overall system cost
2Adaptability or versatility
If an additional camera is arranged on the display device to implement image-taking function, then the image-taking capability is improved, but the device thickness increases
Solution Approach 1:
The image sensing units are integrated within the pixel units of the display panel, merging the image capture function into the existing display structure. This integration eliminates the need for a separate camera module that would increase device thickness, maintaining a thin profile while adding image-taking capability
Solution Approach 2:
The image sensing units are nested within the pixel units, with each pixel unit containing both sub-pixel units and image sensing units. This nested structure allows the image sensing functionality to be embedded within the display panel itself, avoiding additional external components that would increase device thickness
