Display Panel Driving Film Layer Removal Prevents Thermal Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods of manufacturing display panels often result in thermal damage to the driving film layer during slotted area cutting, leading to reduced strength and product quality due to irregular stress patterns and thermal effects during laser cutting.
Innovation Solution
A method involving the provision of a driving film layer on a substrate, removal of a portion of the film layer along a slotting-cutting path, and subsequent cutting of the slotted area using techniques like laser-cutting, cutter wheel-cutting, or CNC machine grinding, with the film layer removal preventing thermal damage and ensuring a stronger screen body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If laser-cutting is performed on the slotted area of the display panel, then the cutting efficiency is improved, but thermal damage occurs to the driving film layer
Solution Approach 1:
The patent applies preliminary action by removing the driving film layer at the slotting area before performing the cutting process. This preparatory step eliminates the thermal-sensitive material from the cutting zone, allowing subsequent laser or CNC cutting to proceed without causing thermal damage to the driving film layer, thus resolving the contradiction between cutting efficiency and thermal damage prevention
2Object-affected harmful factors
If the driving film layer is removed along the slotting-cutting path, then thermal damage is prevented during cutting, but the manufacturing process complexity increases
Solution Approach 1:
The patent integrates the driving film layer removal as a preliminary action that is performed before the cutting process. By incorporating this removal step into the manufacturing sequence, the patent prevents thermal damage during cutting while managing process complexity through systematic integration of the additional step
3Object-affected harmful factors
If a protective layer is provided on the driving film layer before cutting, then thermal damage is prevented, but the manufacturing time and process complexity increase
Solution Approach 1:
The patent compares two approaches: providing a protective layer before cutting versus removing the driving film layer before cutting. The removal approach is selected as it prevents thermal damage without requiring additional protective layer deposition and removal steps, thereby reducing manufacturing time and process complexity compared to the protective layer approach

AI summary
Exemplary embodiments of the present disclosure relate to methods of manufacturing display panels and display panels. The method of manufacturing a display panel includes: preparing a driving film layer on a substrate of the display panel, and removing at least a removal part of the driving film layer along a slotting-cutting path of the display panel; performing a cutting process on a slotted area of the display panel along the slotting-cutting path. By removing at least a removal part of the driving film layer along the slotting-cutting path before performing the cutting process on the slotted area of the display panel, problems such as thermal damage to the driving film layer and the like can be prevented, so that the problem of reducing the strength of the screen body in the slotted area can be avoided, and the quality of the product can be improved.
