Transparent Display Control for Viewpoint-Dependent Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent displays often hinder the view of objects when characters or signs on the screen are not properly aligned with the viewer's perspective, making it difficult for users to see through the display.
Innovation Solution
A display control apparatus and method that acquires position information about the relative positions of the transparent display, viewpoint, and object, and adjusts the display accordingly to ensure the object is viewable from the desired perspective by controlling the display's position and attributes based on this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If characters or signs are displayed on the transparent display screen, then information display capability is improved, but visibility of objects through the display deteriorates
Solution Approach 1:
The patent applies local quality by making different regions of the transparent display have different properties. The display screen is divided into a display region (for showing characters/signs) and a non-display region (for viewing objects). This allows the display to simultaneously provide information display capability in certain areas while maintaining object visibility in other areas, thus resolving the contradiction between these two functions.
2Object-affected harmful factors
If the transparent display is positioned to show objects clearly, then object visibility is improved, but display of information at optimal positions deteriorates
Solution Approach 1:
The patent applies dynamics by making the display region movable or adjustable on the transparent display screen. The display region can be repositioned dynamically based on the user's viewing angle, object position, or other conditions. This allows the system to optimize both object visibility and information display positioning by adapting the display region location in real-time, thus resolving the contradiction between these two requirements.
3Loss of information
If the display region is enlarged to show more information, then information display capability is improved, but the area for viewing objects deteriorates
Solution Approach 1:
The patent applies dimensionality change by utilizing the transparent nature of the display to create overlapping visual layers. Information can be displayed in the foreground while objects are visible through the display in the background, effectively using the transparency dimension to resolve the conflict between display area and viewing area. This allows both functions to coexist without directly competing for the same physical space.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables clear viewing of objects through transparent displays by optimizing the display's settings to avoid interference from on-screen elements, improving user experience and visibility.
Implementation Method 1
The liquid crystal diffuses light when an application voltage is in an off-state, and transmits light when the application voltage is in an on-state.

AI summary
A display control apparatus controls display of a transparent display which includes a screen configured to transmit light arriving from an object located on a side of a second surface so that the object is viewable from a viewpoint located on a side of a first surface which is an opposite surface to the second surface. The display control apparatus includes: an acquisition unit that acquires position information indicating relative positional relations between the transparent display and the viewpoint and between the transparent display and the object; and a display control unit that controls the display of the transparent display based on the position information.
