Innovation Solution
A display device incorporating first to third switches, a transistor, a capacitor, and a light-emitting/receiving element, where the light-emitting/receiving element can emit and receive light, converting it into an electric signal, and is connected through specific wiring configurations to enable both display and image capturing functions with reduced component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display device integrates image capturing functions with separate components, then image capturing capability is achieved, but device complexity and number of components increase
Solution Approach 1:
The patent combines display and image capturing functions into a single integrated device. The display device includes both display elements for displaying images and light-receiving elements for capturing images, eliminating the need for separate camera modules and reducing overall device complexity.
Solution Approach 2:
The display device is designed to perform multiple functions: it can display images through the display element and capture images through the light-receiving element. This multi-functional design allows a single device to replace what would traditionally require separate display and camera devices.
2Measurement precision
If high-definition display and image capturing are implemented with separate components, then high definition is achieved, but power consumption increases
Solution Approach 1:
By integrating the light-receiving element directly into the display device structure, the patent eliminates the need for separate camera components and their associated power consumption. The shared substrate and integrated circuitry reduce overall energy usage while maintaining high-definition capabilities for both display and image capturing.
3Adaptability or versatility
If multiple separate components are used for display and image capturing, then functional versatility is achieved, but the device structure becomes conventional and lacks novelty
Solution Approach 1:
The patent creates a novel integrated structure where display elements and light-receiving elements are combined in a single device architecture. This integration produces a new device type that simultaneously performs display and image capturing functions, representing a structural innovation rather than merely assembling conventional separate components.
