In-Vehicle Display Brightness Control via Viewing Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle display devices with large flat screens often experience inconsistent brightness, leading to poor display effects, and the use of flexible screens to address this issue increases costs.
Innovation Solution
The implementation of a display controlling method that uses at least two display modules arranged in sequence, with the user front-view module displaying at a first brightness and user side-view modules displaying at a second brightness determined based on their viewing angles, which is greater than the first brightness, to ensure consistent brightness perception across the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flat screen is applied to prepare the display screen of the in-vehicle display device, then the cost is reduced, but the brightness perceived by users at each point of the display screen is inconsistent, making the display effect poor
Solution Approach 1:
The patent applies local quality by differentiating brightness settings across different display modules based on their viewing angles. Front-view display modules use a first brightness while side-view display modules use a second brightness (higher than the first) when their viewing angles exceed a threshold. This localized brightness adjustment compensates for the inherent brightness inconsistency of flat screens, ensuring each region provides optimal brightness for its intended viewing direction without requiring expensive flexible screens.
2Illumination intensity
If a flexible screen is used to enable consistent brightness perception, then the display effect is improved, but the cost of the in-vehicle display device increases
Solution Approach 1:
The patent employs parameter changes by dynamically adjusting the brightness parameter of different display modules based on viewing angle conditions. Instead of changing the physical structure (as flexible screens would), the system modifies the brightness parameter software-controlled: front-view modules display at a first brightness, while side-view modules switch to a second brightness (higher than the first) when viewing angles exceed the threshold. This parameter-based solution achieves brightness consistency comparable to flexible screens while maintaining the cost advantages of flat screens.

AI summary
A display controlling method, an in-vehicle display device, and a non-transitory computer-readable medium are provided in the present disclosure. The display controlling method is applied to the in-vehicle display device. The in-vehicle display device includes at least two display modules arranged in sequence along a first direction. The method includes controlling each user front-view display module to display with a first brightness; determining a second brightness corresponding to each user side-view display module based on a viewing angle corresponding to each user side-view display module, the second brightness being greater than the first brightness; and controlling each user side-view display module to display with a corresponding second brightness.
