Cover Lens Convex Portion Borderless Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with frame borders are visually unappealing due to their thickness and visible system frame borders, which interfere with the aesthetic appearance and image display.
Innovation Solution
A display device design incorporating a cover lens with a convex lens portion and a cover portion, where the convex lens portion faces the display area and the cover portion extends outside, featuring a cambered surface that deflects light to enlarge the image and reduce visual interference from the frame borders, creating an effect of a narrow or borderless frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional cover lens with large thickness is used, then the cover lens can provide sufficient structural strength and protection, but the system frame border remains visible and discontinuous joint lines appear, which negatively affects visual aesthetics
Solution Approach 1:
The cover lens is divided into two functional portions: a first portion (convex lens portion) that enlarges the display image, and a second portion (cover portion) that provides structural support and protection. This segmentation allows each portion to be optimized independently - the convex lens portion can be made thinner for better aesthetics while the cover portion maintains structural strength.
Solution Approach 2:
The patent introduces a dimensional transformation by using optical magnification in the optical path dimension. The convex lens portion enlarges the display image, which effectively masks the frame border and joint lines by making them appear smaller relative to the enlarged image, thereby improving visual aesthetics without compromising structural integrity.
2Shape
If the cover lens thickness is reduced to achieve narrow frame border effect, then visual aesthetics improve, but the structural strength and protection capability may be compromised
Solution Approach 1:
By segmenting the cover lens into a first portion and a second portion, the patent enables the first portion to be optimized for optical function with reduced thickness (improving frame border appearance), while the second portion maintains sufficient thickness for structural support and protection capability.
Solution Approach 2:
The second portion (cover portion) serves multiple functions: it provides structural support, offers protection capability, and extends beyond the first portion to maintain the overall strength of the cover lens assembly, thereby compensating for the reduced thickness in the first portion.
3Ease of manufacture
If a conventional cover lens design is used, then manufacturing is simpler, but discontinuous joint lines appear between the cover lens and system frame border, affecting device appearance
Solution Approach 1:
The segmented design with a first portion and a second portion allows the joint line to be strategically positioned and managed. The first portion can be precisely manufactured to match the display area, while the second portion extends beyond it, enabling the joint line to be less visible or aesthetically acceptable while maintaining manufacturing feasibility.
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 design effectively reduces visual interference from the frame borders, enhancing the aesthetic appeal and image display by enlarging the image and adjusting the edges to minimize the visibility of the system frame, resulting in a more seamless and visually appealing display experience.
Implementation Method 1
The first portion is configured to enlarge the whole display image to generate an enlarged image
Implementation Method 2
the cover portion also has a fringe extending outside the convex lens portion. The cover portion has an outer surface, and the outer surface includes a central area and a cambered surface located at outer edges of the central area and connected between the central area and the fringe

AI summary
A display device is provided. The display device includes a display module and a cover lens. The display module has a display area and a non-display area aside the display area. The cover lens which is disposed on the display module and covers the same includes a convex lens portion and a cover portion, wherein the convex lens portion has a convex cover surface facing the display area, the cover portion is connected to a side of the convex lens portion opposite to convex cover surface; the cover portion also has a fringe extending outsides the convex lens portion. The cover portion has an outer surface which includes a central area and a cambered surface connected to the central area and corresponding to the fringe.
