Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices for vehicles face challenges in providing clear and reliable information to drivers and passengers while maintaining a clean and space-efficient interior.
Innovation Solution
A display device with a dual-emission display panel and a light-blocking film, where the display panel can be moved to overlap with the window glass, and the light-blocking film can be adjusted to improve contrast and visibility, especially in bright conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display panel is placed inside the vehicle without overlapping the window glass, then the interior remains clean and space-efficient, but the display clarity and visibility are reduced
Solution Approach 1:
The display panel is designed to be movable between a retracted position (inside the vehicle) and an extended position (overlapping the window glass). The driving unit enables dynamic adjustment of the display panel's position, allowing it to protrude forward to overlap with the window glass when high visibility is needed, and retract when space efficiency is prioritized.
2Reliability
If a light-blocking film is added to improve contrast in bright conditions, then display visibility is enhanced, but device complexity increases
Solution Approach 1:
A light-blocking film is introduced as an intermediary element between the display panel and the external environment. This film can be selectively positioned to block excessive light when the display operates in bright conditions, thereby improving contrast and visibility without fundamentally altering the display panel's core structure.
Solution Approach 2:
The light-blocking film is designed to be movable and adjustable, allowing it to be positioned in front of the display panel when needed for contrast enhancement in bright conditions, and retracted or removed when not needed, thereby maintaining system simplicity when the enhancement is not required.
3Ease of operation
If the display panel is made movable to overlap with window glass, then information accessibility is improved, but device complexity increases
Solution Approach 1:
The display panel is designed to be movable between a retracted position (inside the vehicle) and an extended position (overlapping the window glass). The driving unit enables dynamic adjustment of the display panel's position, allowing it to protrude forward to overlap with the window glass when high visibility is needed, and retract when space efficiency is prioritized.

AI summary
One embodiment of the present invention provides a display device from which a driver or a fellow passenger in a mobile body such as a vehicle can easily obtain desired information. One embodiment of the present invention is a display device including a display panel. The display panel is placed inside a mobile body including window glass. A film including a light-blocking layer is provided between the window glass and the display panel of the mobile body. By providing a driving unit controlling the display panel, the positional relationship between the window glass and the display panel is changed. Alternatively, by providing a driving unit controlling the film including the light-blocking layer, the positional relationship between the window glass and the film including the light-blocking layer is changed.
