Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional packaging methods for quantum dots in glass tubes are complex and result in large non-effective zones, which hinder narrow frame design and efficiency in display devices.
Innovation Solution
A quantum dot glass plate is created using two parallel glass substrates with a glue layer containing rectangular ring-shaped glue frames, where quantum dots are uniformly distributed, allowing for effective sealing and reduction of non-effective zones by cutting along the glue frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional glass tube packaging is used for quantum dots, then the quantum dots are effectively sealed, but the non-effective zone is large and occupies extra space
Solution Approach 1:
The patent divides the continuous glue layer into multiple separate glue frames arranged in a matrix pattern. Each glue frame independently seals quantum dots in specific regions, allowing the non-effective zone to be concentrated only at the edges of each individual frame rather than forming a large continuous border around the entire display area.
Solution Approach 2:
The patent transitions from a traditional single continuous border structure to a two-dimensional matrix arrangement of multiple small glue frames. This dimensional reorganization allows the sealing function to be distributed across many small points rather than requiring a large peripheral zone.
2Reliability
If traditional glass tube packaging is used for quantum dots, then the quantum dots are effectively sealed, but the manufacturing procedure is complicated
Solution Approach 1:
The patent replaces the traditional glass tube structure with a simpler organic glue frame structure that can be directly formed on the substrate. This eliminates the need for separate glass tube fabrication, assembly, and sealing processes, significantly simplifying the manufacturing procedure while maintaining effective sealing.
Solution Approach 2:
The patent replaces the mechanical glass tube sealing system with a chemical/adhesive bonding system using glue frames. The glue frames are formed and cured in place, eliminating complex mechanical assembly steps required for glass tube packaging.
3Reliability
If traditional glass tube packaging is used for quantum dots, then the quantum dots are effectively sealed, but it is difficult to achieve narrow frame design
Solution Approach 1:
By segmenting the sealing structure into multiple small glue frames distributed across the display area, the patent reduces the width of non-effective zones at the edges of each frame. This allows the overall display to achieve narrow frame design while maintaining effective sealing at each quantum dot region.
Solution Approach 2:
The patent applies sealing functionality locally at each glue frame position rather than requiring a continuous large border. This localized approach allows different regions to have different characteristics, with minimal non-effective zones at the edges of individual frames while maintaining effective sealing where needed.
4Area of stationary object
If glue frames with small width are used, then the non-effective zone is reduced, but the manufacturing precision requirement increases
Solution Approach 1:
The patent uses a moderate glue frame width (0.1-1mm) that is excessive enough to be manufacturable with standard precision but small enough to reduce non-effective zones. This partial action approach finds an optimal balance between manufacturing capability and design requirements.
Solution Approach 2:
The patent optimizes the glue frame width parameter to a specific range (0.1-1mm) that balances manufacturing precision requirements with the need to minimize non-effective zones. This parameter optimization allows standard manufacturing processes to achieve the required precision without excessive cost or complexity.
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 method enhances color gamut saturation, improves display quality, reduces non-effective zones, and aligns with narrow frame design principles, increasing production efficiency and reducing costs while being suitable for large-scale applications.
Implementation Method 1
curing the glue layer to form a complex glass plate
Implementation Method 2
An advantage of the quantum dots is based on quantum confinement effect of the semiconducting crystal or quantum size effect of the semiconducting crystal. When size of the semiconducting crystal reaches nanoscale levels, different sizes of the semiconducting crystal can emit different color light.
Implementation Method 3
A traditional blue light emitting diode excites nanoscale-sized quantum dots, which makes NTSC value reach 100% or more

AI summary
A quantum dot glass plate includes a first glass substrate, a second glass substrate correspondingly parallel with the first glass substrate, and a glue layer arranged between the first glass substrate and the second glass substrate, where the glue layer includes at least one glue frame arranged in a line. A shape of the first glass substrate is same as a shape as the second glass substrate, and edges of the glue layer correspond to edges of the first glass substrate and the second glass substrate.
