Vehicle Display Subarea Transparency Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle display devices require high investment and long development periods due to the need for various hardware variants, and users face difficulties in determining the desired level of transparency before purchasing a vehicle, limiting flexibility and handling.
Innovation Solution
A display device with a display screen unit and a sight protection element that adjusts transparency on a subarea basis, using an unlock signal for context-specific or user-specific changes, allowing for different transparency modes without the need for multiple hardware variants, and enabling remote control through an external control module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different hardware variants of display devices are produced for different transparency requirements, then user needs for different transparency levels are met, but development time and financial investment increase significantly
Solution Approach 1:
The patent applies dynamics by making the display device's transparency characteristic changeable over time through a switchable sight protection element. Instead of producing multiple static hardware variants with different transparency levels, a single display device is equipped with a controllable transparency adjustment mechanism that can dynamically switch between transparent and opaque states based on user selection or driving conditions, thereby resolving the contradiction between adaptability and development time
Solution Approach 2:
The patent changes the transparency parameter of the display device from a fixed hardware characteristic to a controllable variable parameter. By introducing a sight protection element whose transparency can be adjusted between different states (transparent, opaque, or intermediate), the system allows users to select different transparency levels without requiring different hardware variants, thus reducing development time while maintaining versatility
2Adaptability or versatility
If different hardware variants of display devices are produced for different transparency requirements, then user needs for different transparency levels are met, but financial investment increases significantly
Solution Approach 1:
The patent applies universality by designing a single display device that can perform multiple transparency functions through one switchable sight protection element. Instead of manufacturing multiple specialized display variants (fully transparent, partially transparent, opaque), the system uses one universal display device that can be switched between different transparency modes, thereby reducing manufacturing complexity and financial investment while maintaining full adaptability to user needs
Solution Approach 2:
The dynamic transparency adjustment capability allows a single hardware variant to replace multiple static variants, reducing the need for diverse manufacturing processes and inventory management, thus lowering overall manufacturing investment
3Object-affected harmful factors
If the entire second layer is made opaque, then visibility protection is provided, but the display cannot show graphical elements through the display surface
Solution Approach 1:
The patent resolves this contradiction by making the sight protection element's transparency dynamic rather than static. The element can switch between opaque (providing visibility protection) and transparent (allowing displayed information to be visible) states, or even intermediate states, based on user selection or driving conditions. This dynamic behavior allows the same element to fulfill both protective and display functions at different times, eliminating the need to choose between them

AI summary
The invention relates to a method for operating a display device (20) of a motor vehicle (10). The display device (20) comprises a display screen unit (22) with a display surface that has several subareas (24, 26, 28), and wherein a sight protection element (30) that is designed to set for each of the subareas (24, 26, 28) a respective degree of a transparency. A control module (36) performs: providing the display screen unit (22) in a basic mode, in which the sight protection element (30) sets the same degree of transparency for each of the subareas (24, 26, 28) (S1), checking whether an unlocking signal is given which grants authorization of a user for using a predetermined subarea unlock mode (S2), and, in case the authorization is given: changing the degree of transparency only of the predetermined subareas (24, 26, 28) to the unlock value (S3).
