OLED Display Disparity Barrier Rib Layer for 3D Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing OLED displays face challenges in effectively displaying high-resolution three-dimensional images while maintaining slimness, as conventional methods using liquid crystals or barrier ribs lead to reduced luminance, increased thickness, and complex manufacturing processes.
Innovation Solution
An OLED display with a substrate, organic light emitting elements, an encapsulation thin film, and a disparity barrier rib layer, where the barrier rib is made of organic or inorganic materials with a light blocking component, integrated with the encapsulation film, and strategically positioned to generate image disparity with precise control over distance, allowing for high-resolution three-dimensional image display and reduced thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a liquid crystal layer is used to display three-dimensional images, then image disparity can be generated, but light transmittance is deteriorated and overall luminance is reduced
Solution Approach 1:
The patent removes the liquid crystal layer from the OLED display structure, extracting the problematic component that caused luminance deterioration. Instead, it uses a barrier rib layer formed directly on the OLED structure to achieve three-dimensional image display without compromising light output.
Solution Approach 2:
The patent creates an alternative solution by copying the essential function of the liquid crystal layer (image disparity generation) through a different mechanism - using barrier ribs with different heights to create optical path differences, thereby achieving the same three-dimensional effect without the harmful liquid crystal layer.
2Adaptability or versatility
If a liquid crystal layer is used for three-dimensional image display, then image disparity is achieved, but manufacturing complexity increases and productivity decreases
Solution Approach 1:
The patent merges the barrier rib layer with the existing OLED structure, integrating the three-dimensional display function into the manufacturing process rather than adding a separate liquid crystal layer. This consolidation simplifies the overall structure and reduces manufacturing steps.
Solution Approach 2:
The barrier rib layer serves multiple functions: it provides structural support, controls pixel spacing, and generates image disparity for three-dimensional display. This multi-functionality eliminates the need for separate liquid crystal components and simplifies the manufacturing process.
3Adaptability or versatility
If a barrier rib is formed on the glass substrate to generate disparity, then three-dimensional image display is enabled, but the overall thickness of the display is increased
Solution Approach 1:
The patent transitions from forming barrier ribs on the glass substrate (adding thickness in the vertical dimension) to forming barrier ribs directly on the OLED structure layers, utilizing the existing layered architecture to achieve the same function with minimal thickness increase.
Solution Approach 2:
The barrier ribs are formed only in specific regions where pixel boundaries exist, rather than uniformly across the entire glass substrate. This localized approach minimizes the overall thickness increase while maintaining the three-dimensional display function where needed.
4Adaptability or versatility
If a barrier rib is formed on the glass substrate, then image disparity is generated, but precise control of the distance between the barrier rib and organic light emitting element is difficult
Solution Approach 1:
The barrier rib layer is formed as part of the OLED manufacturing process before the final encapsulation, allowing precise control of the distance between the barrier rib and the organic light emitting element through standardized deposition techniques. This preliminary formation ensures consistent spacing critical for optimal three-dimensional display performance.
