Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of pixels in a display apparatus increases, the amount of image data transmitted for input to the display apparatus also increases, leading to a higher load on the interface and potential inefficiencies in image display.
Innovation Solution
The display apparatus includes a display portion with a light-emitting portion, a light-receiving portion, and a control portion. The display portion is divided into regions, and the control portion adjusts the screen resolution and frame frequency of each region based on the user's gaze point, reducing the amount of image data transmitted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of pixels in the display apparatus is increased to improve display quality and resolution, then the display quality and resolution are improved, but the amount of image data transmitted increases, leading to higher interface load
Solution Approach 1:
The display panel is divided into multiple regions (first region, second region, third region) with different pixel densities. The first region has high pixel density for detailed display, while the second and third regions have lower pixel densities, reducing the overall amount of image data transmitted while maintaining display quality in the critical first region.
Solution Approach 2:
Different regions of the display panel are assigned different pixel densities based on local requirements. The first region has high pixel density where detailed display is needed, while other regions have reduced pixel density, optimizing the balance between display quality and data transmission load.
2Measurement precision
If the number of pixels is increased to improve display quality, then the display quality is improved, but the power consumption increases
Solution Approach 1:
The display is segmented into regions with different pixel densities. By reducing the pixel density in the second and third regions compared to the first region, the overall power consumption is reduced while maintaining high display quality in the critical first region where users typically focus their attention.
Solution Approach 2:
Different pixel densities are applied to different regions based on local display requirements. This local optimization allows high power consumption to be concentrated only in the first region with high pixel density, while reducing power consumption in other regions.
3Measurement precision
If the number of pixels is increased to improve display quality, then the display quality is improved, but the cost of the display apparatus increases
Solution Approach 1:
The display panel is divided into regions with different pixel densities. This segmentation allows the use of less expensive manufacturing processes in the second and third regions while maintaining high-resolution display in the first region, thereby reducing overall manufacturing costs compared to uniformly high-resolution displays.
Solution Approach 2:
Different pixel densities are implemented in different regions to optimize cost efficiency. The first region uses high pixel density for quality display, while other regions use lower pixel density, reducing manufacturing complexity and cost in those areas.
