Translucent Lens Parts for Display Panel Joint Concealment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with inclined surfaces as lenses struggle to maintain an optimal image shift at the joint between display panels, either reducing image quality due to insufficient thickness or increasing device thickness unnecessarily.
Innovation Solution
A display device with at least two display panel parts having inclined surfaces that form a gap region, where translucent parts protrude from these inclined surfaces to create a refractive effect, allowing for image shifting and minimizing the visibility of the joint between panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the thickness of the cover body is reduced, then the overall device thickness is reduced, but the image shift degree is reduced causing difficulty in displaying the shifted image on the joint
Solution Approach 1:
The invention transitions from using the cover body thickness (vertical dimension) as the lens thickness to using a dedicated lens component that can be positioned in the gap between display panels (horizontal dimension). This allows the lens function to be separated from the cover body thickness constraint, enabling adequate image shift without increasing overall device thickness.
Solution Approach 2:
The invention separates the lens function from the cover body structure by introducing a dedicated lens component. This segmentation allows the lens to be independently optimized for image shifting while the cover body can be made thin for overall device slimness.
2Manufacturing precision
If the thickness of the cover body is increased, then the image shift degree is sufficient, but the overall device thickness increases
Solution Approach 1:
The lens is positioned in the horizontal gap between display panels rather than relying on vertical cover body thickness. This dimensional shift allows sufficient lens thickness for image shifting without increasing the overall device thickness profile.
Solution Approach 2:
A dedicated lens component acts as an intermediary element placed in the gap between display panels. This intermediary provides the necessary optical function for image shifting without requiring the cover body itself to be thick.
3Object-generated harmful factors
If inclined surfaces are used to shift images to the joint, then the joint becomes less noticeable, but the lens portion thickness must be increased to maintain sufficient image shift
Solution Approach 1:
The lens function is segmented from the cover body and implemented as a separate component in the gap region. This allows the lens to be optimized for image shifting to hide joints while the cover body remains thin.
Solution Approach 2:
The lens component serves as an intermediary optical element positioned in the gap between display panels. It provides the necessary image shifting function to make joints less noticeable without requiring increased cover body or lens portion thickness that would affect overall device dimensions.
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
The solution effectively reduces the visibility of the joint between display panels by using translucent parts to shift and connect images across the gap region, enhancing image continuity and reducing the perceived thickness of the display device.
Implementation Method 1
at least one translucent part configured with a material having translucency so as to protrude from the display-side inclined surface part as a starting point toward the adjacent display panel part in the gap region, wherein the translucent part includes in the gap region a translucent-side inclined surface that is inclined from one side to the other side of the display panel part in a thickness direction

AI summary
A display device includes: a display having two display panels each having a display-side inclined surface near an outer edge of a display surface, the display being configured to allow parallel arrangement of the two display panels such that the respective inclined surfaces face each other at a joint of the two display panels to form a gap between the inclined surfaces; and at least one translucent part protruding from the display-side inclined surface toward the adjacent display panel in the gap, wherein the translucent part includes in the gap a translucent-side inclined surface that is inclined from one side of the display panel to the other while extending in a direction where the adjacent display panel parts are arrayed.
