Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an illumination sensor is installed in a specific location of the electronic device, then the device structure is simplified and manufacturing is easier, but the sensor cannot accurately detect the brightness of surroundings
Solution Approach 1:
The patent merges the illumination sensing function with the display panel by integrating light-receiving pixels directly into the display structure. These light-receiving pixels are combined with light-emitting pixels to form a unified display panel that can both display images and detect surrounding brightness, eliminating the need for separate illumination sensors and their complex placement considerations.
Solution Approach 2:
The display panel is given multiple functions: it serves as both the light-emitting display surface and the light-receiving sensing element. The light-receiving pixels integrated into the display panel enable brightness detection while maintaining the display's primary function, making the display panel a multi-functional component that eliminates the need for dedicated sensor hardware.
2Use of energy by moving object
If the display panel brightness is controlled based on inaccurate sensor data, then power consumption can be reduced, but display quality and user experience deteriorate
Solution Approach 1:
By integrating light-receiving pixels directly into the display panel, the system achieves accurate measurement of surrounding brightness without requiring separate sensors. This merged structure ensures that the brightness detection is performed at the same location where display occurs, providing accurate data for power consumption optimization while maintaining display quality.
Solution Approach 2:
The light-receiving pixels provide real-time feedback on surrounding brightness conditions to the control unit, which adjusts display brightness accordingly. This feedback mechanism enables dynamic power consumption optimization based on actual environmental conditions while maintaining optimal display quality through accurate brightness sensing.
3Measurement precision
If light-receiving pixels are integrated with light-emitting pixels in the display panel, then accurate brightness detection is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent combines light-emitting pixels and light-receiving pixels into a single integrated display panel structure. This merging allows both functions to be manufactured together using coordinated processes, where the light-receiving pixels are positioned in specific regions (such as bezel areas or between light-emitting pixels) without requiring completely separate manufacturing lines or assembly steps.
4Use of energy by moving object
If the display panel is partially switched off to save power, then battery consumption is reduced, but display functionality is compromised
Solution Approach 1:
The display panel is segmented into light-emitting pixels and light-receiving pixels, with the light-receiving pixels strategically positioned in areas such as the bezel or between display pixels. This segmentation allows the light-receiving pixels to perform sensing functions in non-critical display areas while light-emitting pixels maintain full display functionality, enabling partial power reduction without compromising user experience.
Solution Approach 2:
Different regions of the display panel are assigned different functions: light-emitting pixels provide display output while light-receiving pixels provide sensing input. This local differentiation allows the system to optimize power consumption by controlling only the light-emitting portions while maintaining sensing capability in light-receiving portions, preserving display functionality while reducing power usage.
