Deformable Display Back Plate Curvature Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable curved display devices often fail to maintain a consistent curvature suitable for viewing, leading to a reduced viewing effect due to deformation characteristics of the back plate and display panel.
Innovation Solution
A housing with a deformable back plate and curvature retaining units, comprising pivotably mounted supporting members that can switch between supporting and non-supporting states to maintain a curved shape suitable for watching, applying uniform forces to counteract restoring forces and retain the desired curvature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an adjusting mechanism applies forces at both ends of the back plate to bend it, then the curvature of the display panel can be adjusted, but the maintained curved shape is inconsistent with the suitable viewing curvature due to deformation characteristics
Solution Approach 1:
The adjusting mechanism is divided into multiple independent adjusting units, each capable of applying force at specific locations. This segmentation allows for more precise control over the back plate's deformation, enabling the system to achieve and maintain the desired curvature profile by independently adjusting different segments of the back plate rather than applying uniform force at both ends.
Solution Approach 2:
The adjusting mechanism pre-applies forces to the back plate to compensate for its deformation characteristics before the display panel is assembled. By performing preliminary adjustment and compensation for expected deformations, the system ensures that the back plate maintains the correct curved shape during operation, resulting in consistent viewing curvature across different adjustment positions.
2Adaptability or versatility
If the back plate and display panel are allowed to deform freely, then the adjusting mechanism can change curvature, but the maintained shape deviates from the optimal viewing curvature
Solution Approach 1:
The adjusting mechanism changes physical parameters such as force magnitude, application points, and distribution patterns to achieve the desired back plate curvature. By precisely controlling these parameters, the system can counteract the natural deformation tendencies of the back plate and display panel, maintaining a consistent optimal viewing curvature across different adjustment positions.
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 ensures a consistently suitable curved shape for the display panel, enhancing the viewing experience by maintaining a regularly curved shape that is optimal for viewing, unlike existing technologies which apply forces at both ends and result in inconsistent curvature.
Implementation Method 1
a back plate configured to be deformable to change its curvature
Implementation Method 2
Each curvature retaining unit has a non-supporting state in which the back plate is in a flat state and a supporting state in which two opposite sides of adjacent supporting members abut against each other such that the back plate is in a bended shape

AI summary
A housing for a display device is disclosed. The housing includes a back plate configured to be deformable to change its curvature; and at least one curvature retaining unit located on a convex side of the back plate in the case of the back plate being bent. Each curvature retaining unit includes a plurality of supporting members arranged in a row, a first side of each of the supporting members is pivotably mounted to the back plate, and each curvature retaining unit has a non-supporting state and a supporting state. In the non-supporting state of the curvature retaining unit, the back plate is in a flat state; and in the supporting state of the curvature retaining unit, two opposite sides of adjacent supporting members abut against each other such that the back plate is in a bended shape.
