Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing multi-layer display screens using multiple adhesive layers result in increased thickness, longer assembly times, higher resource consumption, and increased costs, with difficult repair processes due to repeated lamination.
Innovation Solution
A method involving a screen frame made of transparent material that allows UV light through, where screen components are stacked within the frame and a UV-curable bonding substance is used to fill the gaps, hardening to bond the components securely without the need for multiple adhesive layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple adhesive layers are used for lamination, then the layers can be bonded together, but the screen thickness increases substantially
Solution Approach 1:
The patent merges multiple separate lamination operations into a single simultaneous bonding process. All layers are stacked and bonded together at once using a single application of bonding substance, eliminating the need for multiple sequential adhesive layers and reducing overall screen thickness while maintaining bonding strength.
Solution Approach 2:
The patent extracts and eliminates the intermediate adhesive substrate layers from the traditional multi-step lamination process. By removing these separate adhesive components and using a direct bonding substance applied to the frame, the screen thickness is reduced while the bonding function is preserved.
2Strength
If repeated lamination process is used, then adjacent layers can be bonded one by one, but the assembly time increases
Solution Approach 1:
The patent combines multiple sequential lamination steps into a single simultaneous bonding operation. All layers are positioned and bonded together in one process cycle, eliminating the repeated sequential operations of traditional lamination and dramatically reducing assembly time while maintaining adequate bonding strength.
Solution Approach 2:
The patent performs preliminary stacking and positioning of all layers before the bonding process begins. This preliminary arrangement allows the bonding substance to be applied once to secure all layers simultaneously, rather than requiring repeated bonding operations for each layer pair.
3Strength
If repeated lamination process is used, then layers can be bonded sequentially, but resource consumption and costs increase
Solution Approach 1:
The patent merges multiple resource-intensive lamination steps into a single bonding operation. By applying bonding substance once to secure all layers simultaneously, the consumption of bonding materials, energy, and other resources is reduced compared to repeated sequential lamination processes.
Solution Approach 2:
The patent removes the intermediate adhesive substrates and their associated application processes from the traditional lamination method. This extraction eliminates the need for multiple separate adhesive materials and reduces overall resource consumption while maintaining bonding functionality.
4Strength
If multiple adhesive layers are used, then bonding can be achieved, but the rendering properties decrease
Solution Approach 1:
The patent extracts and removes the intermediate adhesive substrate layers that interfere with optical rendering properties. By bonding layers directly to each other without opaque or semi-transparent adhesive intermediates, the display's light transmission and overall rendering quality are improved while bonding strength is maintained through the bonding substance applied at the frame.
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
This approach reduces assembly time and costs, maintains transparency, and simplifies the repair process by bonding multiple layers simultaneously, resulting in a more efficient and cost-effective multi-layer display screen production.
Implementation Method 1
A UV-curable bonding substance may be delivered into the frame around the stack. The bonding substance may be caused to harden, for example, by curing the substance with ultraviolet (UV) light

AI summary
Embodiments of an electronic device with an assembled multi-layered display screen and methods for a multi-layered screen assembly are disclosed herein. In one instance, the method may include disposing a frame for a display screen upon a base comprising a substantially flat surface and substantially corresponding to a shape of the display screen, assembling the display screen by stacking multiple components within the frame such that the assembled display screen faces the base, and delivering a bonding substance into the frame such that the bonding substance substantially fills the frame to the depth of the frame and around the stacked multiple components. The substance may be allowed to harden to a solid state thus bonding the assembly. The frame may have a depth substantially corresponding to a thickness of the assembled display screen. Other embodiments may be described and/or claimed.
