Solution Overview
Problem
Glass backplanes for liquid crystal display devices face limitations due to fragility, poor impact resistance, and light transmission issues, restricting their widespread application.
Innovation Solution
A glass backplane comprising a tempered glass substrate, a light-shielding layer, and a reflective layer is developed. The light-shielding layer is disposed on one side of the tempered glass substrate, and the reflective layer is positioned on the side of the light-shielding layer, enhancing impact resistance and reducing light transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a glass backplane is used in liquid crystal display devices, then advantages such as good flatness, light and thin design, anti-glare properties, and weather resistance are achieved, but disadvantages including fragility, poor impact resistance, and light transmission issues occur
Solution Approach 1:
The patent applies composite materials by combining glass substrate with multiple functional layers including light-shielding layer, reflective layer, and protective coating layers. This composite structure enhances the overall strength and impact resistance of the backplane while maintaining the inherent advantages of glass material such as flatness and weather resistance.
Solution Approach 2:
The patent employs parameter changes by treating the glass substrate through chemical tempering or ion exchange processes that modify the physical and chemical parameters of the glass surface. This creates compressive stress layers that significantly improve impact resistance and reduce fragility without altering the fundamental glass properties.
2Illumination intensity
If a glass backplane is used in liquid crystal display devices, then advantages such as good flatness, light and thin design, anti-glare properties, and weather resistance are achieved, but disadvantages including fragility, poor impact resistance, and light transmission issues occur
Solution Approach 1:
The patent applies local quality by implementing light-shielding layers in specific regions where light transmission needs to be controlled. The light-shielding layer is selectively positioned to block unwanted light transmission while leaving other areas transparent, thus addressing light transmission issues locally without compromising overall display performance.
Solution Approach 2:
The patent employs color changes through the use of light-shielding layers with specific optical properties that absorb or reflect certain wavelengths of light. By controlling the optical characteristics of these layers, the patent manages light transmission and prevents harmful light effects while maintaining desired visual properties.
3Strength
If multiple layers are added to improve impact resistance and reduce light transmission, then the structural complexity increases, but the lightweight and thin design advantages may be compromised
Solution Approach 1:
The patent applies universality by designing functional layers that perform multiple functions simultaneously. For example, the light-shielding layer not only controls light transmission but also provides structural reinforcement, while the reflective layer enhances both optical performance and mechanical strength. This multi-functionality reduces the need for additional separate layers, thereby limiting the increase in structural complexity.
Solution Approach 2:
The patent employs merging by combining multiple functions into integrated layers. Rather than adding separate layers for light shielding, reflection, and structural support, the patent integrates these functions into a unified multi-layer structure where each layer contributes to both optical and mechanical performance, thus minimizing the overall structural complexity.

AI summary
A glass backplane includes a tempered glass substrate, a light-shielding layer and a reflective layer. Two opposite sides of the tempered glass substrate are a first side and a second side. The light-shielding layer is disposed on the first side of the tempered glass substrate, two opposite sides of the light-shielding layer are a first side and a second side, and the second side of the light-shielding layer is closer to the tempered glass substrate than the first side of the light-shielding layer. The reflective layer is disposed at the first side of the light-shielding layer.
