Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display systems for complexly shaped surfaces like automobile windshields require high power consumption due to the need for large frame memories and high-throughput image processing, which hinders visibility and efficiency.
Innovation Solution
A display system with a display panel divided into regions of different sizes, using a display driver that modulates clock frequencies to optimize image processing based on the driver's position, reducing power consumption and improving visibility by spatially compressing or decompressing image data accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image processing is performed using a large-scale frame memory and high-throughput image processing circuit or GPU to display information on a curved automobile windshield, then the display quality and visibility are improved, but the power consumption increases significantly
Solution Approach 1:
The display panel is divided into a first display region and a second display region with different clock signal frequencies. The first region (peripheral/curved area) uses a lower clock frequency while the second region (central/flat area) uses a higher clock frequency, allowing differentiated processing that reduces overall power consumption while maintaining necessary display quality in each region
Solution Approach 2:
Different clock signal frequencies are applied to different regions of the display panel based on their specific requirements. The first display region receives a first clock signal with a frequency lower than the second clock signal frequency used for the second display region, optimizing performance and power consumption locally for each area
2Productivity
If the display panel uses a uniform high clock frequency across all regions to ensure adequate image processing throughput, then the display quality is maintained, but the power consumption increases
Solution Approach 1:
The system dynamically adjusts clock signal frequencies based on regional requirements rather than using a static uniform frequency. The display driver circuit generates different clock frequencies for different display regions, allowing the system to optimize the balance between processing throughput and power consumption adaptively
Solution Approach 2:
The clock signal frequency parameter is changed across different regions of the display panel. By varying this critical parameter spatially, the system achieves adequate image processing throughput where needed while reducing power consumption in regions that require lower processing demands

AI summary
A novel display system and a moving object are provided. The display system includes a display panel and a display driver. The display panel has a curved shape. The display panel includes a first display region and a second display region on the curved surface. The display driver generates first analog data by a first clock signal and first digital data and generates second analog data by a second clock signal and second digital data. An image can be displayed in accordance with the curved shape of the display panel by transmitting the first analog data to the first display region and transmitting the second analog data to the second display region.
