Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in manufacturing display panels is controlling the thickness and area of the quantum dot material layer, which affects light conversion efficiency and display effect, and results in material waste due to uneven distribution and flow between adjacent backlight units.
Innovation Solution
A manufacturing method involving the formation of partitions between backlight units to control the thickness and area of the filter layer, using a bonding glue for stable adhesion and subsequent debonding, and precise application of quantum dot and transparent materials to restrict flow and waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If quantum dot material is applied on backlight units without partitions, then material coverage is complete, but thickness and area of the material layer cannot be controlled precisely and material flows into gaps between adjacent backlight units
Solution Approach 1:
The patent introduces partitions that divide the substrate into separate regions for each backlight unit. These partitions physically segment the application area, preventing quantum dot material from flowing between adjacent backlight units. The partitions create isolated zones where material can be precisely controlled in thickness and area without interfering with neighboring units.
Solution Approach 2:
The partitions act as intermediary structures between adjacent backlight units. They serve as physical barriers that mediate the material application process, containing the quantum dot material within designated areas and preventing unwanted flow into gaps between units, thereby enabling precise thickness and area control.
2Ease of manufacture
If quantum dot material layer thickness and area are not precisely controlled, then material application is simple, but light conversion efficiency and display effect are affected
Solution Approach 1:
By segmenting the substrate into distinct regions with partitions, the patent enables independent control of material thickness and area for each backlight unit. This segmentation allows for precise material deposition within each zone while maintaining a relatively simple overall application process, as the partitions naturally define the boundaries without requiring complex deposition control mechanisms.

AI summary
A manufacturing method of a display panel, a display panel, and a display apparatus. The manufacturing method includes: forming a plurality of backlight units on a process substrate; filling a partition between adjacent backlight units, where a height of the partition relative to the process substrate is greater than a height of the adjacent backlight units relative to the process substrate; preparing a filter layer on a surface of each of the plurality of backlight units away from the process substrate; stripping the backlight units with the filter layer on surfaces of the backlight units from the process substrate, and transferring to a target substrate; and packaging the target substrate.
