Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-screen electronic devices with panels from the same manufacturer can exhibit noticeable differences in chrominance and luminance, leading to inconsistent and discontinuous visual experiences for users due to color discrepancies across displays.
Innovation Solution
A multi-screen color correction method involving an electronic device with at least two display panels and a processor that obtains image characteristics, performs parameter operations to derive image correction parameters, corrects chrominance, and adjusts luminance to minimize color differences between panels, ensuring consistent and continuous display effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display panels are used in an electronic device, then the display area and functionality are improved, but color consistency and visual continuity deteriorate due to panel differences
Solution Approach 1:
The patent applies parameter changes by measuring actual chrominance and luminance values of each panel and adjusting display parameters (gamma correction curves, color transformation matrices) to compensate for panel variations. This transforms the physical display characteristics of each panel to achieve uniform visual output across multiple panels.
2Manufacturing precision
If display panels are corrected for color consistency, then visual perception is improved, but measurement and calibration complexity increases
Solution Approach 1:
The system performs self-calibration by automatically measuring its own display characteristics using integrated sensors or external measurement devices, generating correction parameters without requiring manual intervention. The device serves itself to identify and compensate for its own display variations.
Solution Approach 2:
The patent implements feedback mechanisms where measured chrominance and luminance values are fed back to the processing unit, which then adjusts display parameters based on the measured deviations from target values. This closed-loop control continues until color consistency requirements are met.
