Flexible Display Panel Correction for Curved Instrument Clusters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fabrication costs of complex-shaped instrument panels using curved displays increase due to the need for multiple differently shaped display panels, and existing technologies do not effectively manage visibility and design improvements while controlling these costs.
Innovation Solution
A display system comprising flexible display panels with a correction circuit and memory circuit that stores data for both display and non-display regions, allowing image data generation only for display regions, reducing unnecessary data writing and power consumption, and enabling efficient combination of differently shaped panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If multiple differently shaped display panels are used to form complex-shaped instrument panels, then design improvement and visibility are enhanced, but fabrication costs increase
Solution Approach 1:
A single rectangular display panel is designed to serve multiple functions by displaying different types of information (speed, fuel, temperature, navigation, etc.) in different regions, eliminating the need for multiple specialized display panels and reducing fabrication costs
2Illumination intensity
If multiple differently shaped display panels are combined, then visibility and design are improved, but device complexity increases
Solution Approach 1:
The rectangular display panel is divided into multiple functional display regions (first display region for speed/fuel, second display region for temperature/navigation, third display region for additional information), allowing complex information presentation while maintaining a simple single-panel structure
3Measurement precision
If image data is written to all regions including non-display regions when the panel is bent, then power consumption increases, but if correction is not applied, display accuracy decreases
Solution Approach 1:
The correction circuit extracts and identifies the actual display region from the entire rectangular panel by using stored position information, and selectively processes only the relevant display regions while excluding non-display regions, thereby reducing power consumption without compromising display accuracy

AI summary
A display system and vehicle that have novel structures are provided. The display system includes a display panel, a correction circuit, and a memory circuit. The display panel is flexible. The display panel includes a display region and a non-display region. The memory circuit has a function of storing first data about the display region and second data about the non-display region. The non-display region has a region which overlaps with the display region when the display panel is bent. The correction circuit has a function of generating image data to be written to pixels in the display region on the basis of the first data and the second data.
