Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cameras are used to obtain compensation basic data for multiple display panels, then the accuracy and reliability of data acquisition is improved, but the hardware cost increases and production efficiency decreases
Solution Approach 1:
The image sensing board is divided into multiple obtaining regions, where each region can independently capture display images. This segmentation allows a single camera to simultaneously acquire data from multiple display panels through different regions, eliminating the need for multiple cameras while maintaining data acquisition reliability and improving production efficiency
Solution Approach 2:
The image sensing board is designed to perform multiple functions by using different obtaining regions for capturing images of different display panels simultaneously. This multi-functionality allows one camera system to replace multiple cameras, reducing hardware costs while maintaining the ability to reliably acquire compensation basic data for multiple panels
2Productivity
If multiple cameras are used to simultaneously capture display images of multiple display panels, then the capturing efficiency is improved, but the hardware cost increases
Solution Approach 1:
The image sensing board is divided into multiple obtaining regions that can simultaneously capture images of multiple display panels. This segmentation enables a single camera to achieve the simultaneous capturing capability that would otherwise require multiple cameras, improving capturing efficiency while reducing hardware costs and device complexity
Solution Approach 2:
Multiple obtaining regions on a single image sensing board are merged to perform the function of multiple separate cameras. By combining the capturing capabilities of different regions into one camera system, the patent achieves simultaneous capture of multiple display panels without the need for multiple camera devices, thereby reducing hardware costs while maintaining high capturing efficiency
3Productivity
If different obtaining regions of the image sensing board are used to obtain compensation basic data, then the simultaneous acquisition of data for multiple display panels is achieved, but the uniformity of obtained data may deteriorate
Solution Approach 1:
Uniformity compensation is performed on the image sensing board before using different obtaining regions to capture display images. This preliminary compensation action corrects potential uniformity issues in advance, ensuring that data obtained from different regions maintains consistent quality and uniformity while enabling simultaneous acquisition of compensation basic data for multiple display panels

AI summary
Embodiments of the present application disclose a method, an apparatus, and a system for obtaining compensation basic data of a display panel. Compensation basic data of different display panels is obtained simultaneously by using different obtaining regions of an image sensing board of a camera; and before the basic compensation data is obtained, uniformity compensation is performed on the image sensing board of the camera, and a difference in compensation basic data when the same display image is obtained by using a plurality of obtaining regions obtained by dividing the image sensing board is less than or equal to a set threshold. This reduces errors in the obtained compensation basic data due to poor uniformity of the plurality of obtaining regions of the image sensing board of the camera, thereby ensuring the accuracy of compensation data determined based on the compensation basic data.
