Display Panel Supporting Structure Height Difference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display panels face challenges in maintaining sufficient height difference between supporting structures, which affects the image quality due to inadequate space for liquid crystal molecules.
Innovation Solution
The display panel design includes a color resist layer with varying height supporting structures, where first supporting structures are taller than second supporting structures, and connecting color resistances link the color resistances without spacing, allowing for increased space between them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If supporting structures are disposed between adjacent color resistances, then the supporting structures provide mechanical support, but the height difference between supporting structures is insufficient which affects image quality
Solution Approach 1:
The supporting structures are segmented into two distinct types: first supporting structures disposed between adjacent first color resistances, and second supporting structures disposed between adjacent second color resistances. This segmentation allows each type of supporting structure to have optimized heights independently, achieving sufficient height difference for image quality while maintaining clear structural organization.
Solution Approach 2:
Different supporting structures are assigned different local qualities (heights) based on their positions. The first supporting structures have a first height, while the second supporting structures have a second height different from the first height. This local differentiation optimizes the height difference between supporting structures to improve image quality without requiring uniform structural changes throughout the device.
2Area of stationary object
If color resistances are disposed close together, then the device area is reduced, but the space for liquid crystal molecules becomes insufficient affecting image quality
Solution Approach 1:
The patent transitions from a two-dimensional planar arrangement to a three-dimensional structure by varying the heights of supporting structures. The first supporting structures extend to a first height and the second supporting structures extend to a second height, creating vertical dimensionality that provides sufficient space for liquid crystal molecules while keeping the horizontal device area compact.
Solution Approach 2:
The supporting structures are nested within the color resistance patterns, with first supporting structures positioned between adjacent first color resistances and second supporting structures positioned between adjacent second color resistances. This nesting arrangement optimizes space utilization, allowing sufficient vertical space for liquid crystal molecules without increasing the horizontal device area.
