Display Device Lens Array Support and Gap Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stereoscopic video display devices face challenges in achieving uniform lens-pixel gaps, leading to non-uniform display characteristics and difficulty in maintaining stability, especially as the size of the screen increases, due to the weight of the lens array unit causing warping and non-uniformity in the lens-pixel gap.
Innovation Solution
A display device configuration that includes a lens array unit, a display unit with a gap control layer forming a predetermined gap between the display unit and the lens array unit, and a support member fixing both units outside the display area, ensuring a uniform lens-pixel gap through the use of a gap control layer and support member to stabilize the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the lens array unit is directly attached to the display unit without additional support structures, then the device complexity is reduced, but the lens-pixel gap uniformity deteriorates due to warping caused by the weight of the lens array unit
Solution Approach 1:
A support member is introduced as an intermediary component between the lens array unit and the display unit. This support member bears the weight of the lens array unit, preventing warping of the display unit and ensuring uniform lens-pixel gap across the display area, thereby resolving the contradiction between structural simplicity and gap uniformity.
Solution Approach 2:
The support structure is segmented into a support member that is positioned at specific locations (outside the display area) rather than covering the entire structure. This segmentation allows the support function to be provided without adding excessive complexity to the overall device structure.
2Stability of the object's composition
If the lens array unit is fixed tightly to the display unit, then structural stability is improved, but the lens-pixel gap uniformity deteriorates due to warping caused by the weight of the lens array unit
Solution Approach 1:
The support member acts as a mediator that provides structural stability by bearing the weight of the lens array unit, while simultaneously preventing warping of the display unit. This ensures that the lens-pixel gap remains uniform across the display area, resolving the contradiction between structural stability and gap uniformity.
3Area of stationary object
If the screen size is increased, then the display area is enlarged, but the lens-pixel gap uniformity deteriorates due to increased warping from the weight of the lens array unit
Solution Approach 1:
The support member serves as a mediator that counteracts the increased warping effects caused by larger screen sizes. By positioning the support member to bear the weight of the lens array unit, it prevents warping of the display unit even as the display area increases, thereby maintaining lens-pixel gap uniformity across larger screens.

AI summary
A display device includes a lens array unit, a display unit which is configured such that a first substrate is attached to a second substrate that is disposed between the first substrate and the lens array unit, the display unit having a display area composed of matrix-arrayed pixels, a gap control layer which forms a predetermined gap between the display unit and the lens array unit, and a support member which fixes the display unit and the lens array unit on an outside of the display area of the display unit.
