Extendable Vehicle Display Screen for Content Shift Without Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices for motor vehicles often cover or reduce the original content on a central display when shifting display content from a passenger display to the central display.
Innovation Solution
A display device with an extendable screen that moves out of the central display housing when content is shifted from a passenger display, allowing the original central display content to remain unchanged and the shifted content to be displayed on the extended screen.
Engineering Contradictions & Design Principles

If central display screen is extended outward to display moved content, then both original and moved content can be displayed, but device complexity increases
Solution Approach 1:
The extendable display mechanism serves multiple functions: it acts as a structural support for the display screen, provides the extension and retraction movement, and integrates with the control system to detect when content moving operations are in progress. This multi-functionality reduces the need for separate components and reduces overall system complexity despite the added capability.
Solution Approach 2:
The patent merges the display screen with the extending mechanism into a single integrated unit. The screen and its support structure are combined with the extension mechanism, allowing the entire assembly to move outward and inward as one unit. This merging reduces the number of separate components and simplifies the overall device structure.

AI summary
The invention relates to a method for displaying display content on an extendable screen (26) and to a display device (12) for a motor vehicle (10). The display device (12) comprises at least one first and one second screen (14, 16) which are designed to each display display contents, wherein an extendable screen (26) is arranged in a housing of the display device (12) and can be moved by an adjusting device (24) between an extended position, in which the extendable screen (26) is moved out of the housing, and a retracted position, in which the extendable screen (26) is recessed in the housing, wherein the display device (12) further has a control unit (22) which is designed to actuate the adjusting device (4) to move the extendable screen (26) into the extended position and to display the display content on the extendable screen (26) when a user action for moving display content from the second screen (16) to the first screen (14) is detected.
