Solution Overview
Problem
Existing dual-view display panels face challenges in manufacturing due to factors like uneven glass layers and gap distances, leading to superimposed images and a narrowed viewing angle range, which affects production yield and imaging quality.
Innovation Solution
The method involves thinning glass substrates, forming patterned barrier layers, and using a planarization layer and liquid transparent materials to improve light transmission and uniformity, reducing the number of glass layers and filling gaps with liquid materials to enhance viewing angles and production efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple glass layers are used in the dual-view display panel, then the structural strength is improved, but the viewing angle range is narrowed and light transmission is reduced
Solution Approach 1:
The patent removes the second glass substrate from the conventional dual-view display structure, retaining only the first glass substrate. This extraction of the unnecessary second glass layer reduces light transmission barriers and eliminates the gap between substrates, thereby widening the viewing angle range while maintaining sufficient structural strength through the remaining single glass substrate and optimized barrier layer configuration.
Solution Approach 2:
The patent applies local quality by creating a patterned barrier layer with varying thickness and optical properties in different regions. The barrier layer includes opaque barrier patterns and transparent regions with controlled thickness, allowing different areas to perform specialized functions: the opaque regions block light for dual-view effect while the transparent regions maintain light transmission, thus resolving the contradiction between structural integrity and viewing angle.
2Reliability
If the barrier layer thickness is increased to improve blocking effect, then the dual-view effect is enhanced, but the light transmission is reduced and viewing angle is narrowed
Solution Approach 1:
The barrier layer is designed with local quality variations, comprising opaque barrier patterns for light blocking and transparent regions with controlled thickness for light transmission. This localized differentiation allows the barrier layer to provide effective dual-view blocking in specific areas while maintaining high light transmission in other areas, thus enhancing the dual-view effect without sacrificing overall light transmission and viewing angle.
Solution Approach 2:
The patent optimizes the thickness parameter of the barrier layer, controlling it within a specific range (50-200 micrometers) to achieve the optimal balance between blocking effect and light transmission. By precisely controlling the thickness parameter and the width of transparent regions, the patent ensures sufficient dual-view effect while maintaining adequate light transmission and wide viewing angle.
3Reliability
If the gap between substrates is increased to accommodate barrier layer, then the barrier function is improved, but the viewing angle range is narrowed
Solution Approach 1:
The patent eliminates the second glass substrate entirely, removing the substrate gap that normally exists in conventional display structures. By taking out the unnecessary second substrate, the patent eliminates the gap-related viewing angle limitation while maintaining the barrier function through the optimized barrier layer on the single remaining glass substrate.
Solution Approach 2:
The patent transitions from a three-dimensional gap structure to a two-dimensional barrier layer structure by removing the second substrate. This dimensional change eliminates the depth-related viewing angle constraints while maintaining the light blocking function through the patterned barrier layer, thus widening the viewing angle range without compromising the barrier effect.

AI summary
A dual view display structure and a method for producing the same are provided. First, a display panel is provided. Then, a patterned barrier layer is formed on a transparent substrate. The transparent substrate with the patterned barrier layer is attached to the display panel. Because there is a gap between the display panel and the patterned barrier layer, a liquid transparent material is injected into the gap to form a transparent material layer to fill the gap. The invention can not only increase the viewing angles of the dual view display, but also increase the production yield.
