Display Panel Spacer Positioning via Pixel Array Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The slippage of spacers in display panels can damage internal components, leading to poor display quality due to the lack of stability between substrates.
Innovation Solution
A display panel design featuring a pixel array structure with distinct platform, support, and display regions, where the spacer is positioned in the platform region to prevent direct contact with the display region, maintaining ideal display quality by ensuring the spacer does not easily contact the pixel array structure during slippage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spacer is placed between the two substrates to maintain spacing distance, then the spacing stability is improved, but the spacer may slip and contact the pixel array structure causing damage
Solution Approach 1:
The pixel array structure is divided into three distinct regions: platform region, support region, and display region. The support region acts as a protective barrier between the spacer and the display region, segmenting the potential damage path and preventing spacer slippage from reaching critical components.
Solution Approach 2:
The support region serves as an intermediary protective layer between the spacer and the display region. When the spacer slips, it contacts the support region first, which absorbs the impact and prevents direct contact with the pixel array structure in the display region.
2Manufacturing precision
If the spacer is positioned to abut against the substrate, then the spacing distance is maintained, but the spacer is not fixed and may slip during assembly or use
Solution Approach 1:
Different regions of the pixel array structure are designed with different heights and properties. The platform region has a greater height than the display region, creating a localized structural feature that guides and stabilizes the spacer position while maintaining the required spacing distance.
Solution Approach 2:
The support region is pre-configured with a specific height and structure before the spacer is installed. This preliminary structural arrangement ensures that when the spacer is placed, it naturally settles into a stable position on the support region, preventing slippage during assembly and use.
3Ease of operation
If the pixel array structure is exposed in the display region, then the display function is achieved, but the components are vulnerable to damage from spacer slippage
Solution Approach 1:
The pixel array structure is segmented into display region and support region, where the support region provides protection while the display region maintains functionality. This segmentation allows the display components to be exposed for operation while being shielded from mechanical damage by the elevated support structure.
Solution Approach 2:
The support region acts as an intermediary protective structure between the spacer and the display region components. It mediates the interaction by providing a physical barrier that protects vulnerable display components while allowing the display function to operate normally.

AI summary
A display panel including a first substrate, a second substrate, and a display medium layer, a pixel array structure, and a first spacer that are disposed between the first substrate and the second substrate is provided. The pixel array structure includes a first signal line, and has a first platform region located on the first signal line, a first display region and a first support region located between the first platform region and the first display region. A first platform top surface of the first platform region and the first substrate are spaced by a first distance. A support top surface of the first support region and the first substrate are spaced by a second distance. A display top surface of the first display region and the first substrate are spaced by a third distance. A terminal surface of the first spacer contacts the first platform top surface.
