Optical Display Manufacturing Pivot Mechanism for Dual-Mode Lamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical display element manufacturing systems can only produce one mode of liquid crystal panel, either O mode or E mode, depending on the direction of optical film lamination, limiting the versatility of the manufacturing line.
Innovation Solution
A system and method that allows the manufacture of optical display elements with different lamination directions by using a single manufacturing line, where a panel is supplied and transported with optical films laminated on both planes, with the first laminating unit applying the optical film in a direction parallel to the transport direction and the second unit applying it orthogonally, utilizing a pivot mechanism to reverse the panel's long and short edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a manufacturing system uses separate laminating apparatuses for light source side and observer side substrates, then the lamination process can be performed for both modes, but the system can only manufacture one mode of liquid crystal panel at a time
Solution Approach 1:
The patent applies multi-functionality by enabling a single laminating apparatus to perform lamination operations for both light source side and observer side substrates. The apparatus can be configured to laminate optical films in different directions (long edge direction and short edge direction) depending on the panel mode (E-mode or O-mode), thereby manufacturing both types of liquid crystal panels using the same equipment without requiring separate dedicated apparatuses for each mode
Solution Approach 2:
The patent implements dynamics by making the laminating apparatus adjustable and reconfigurable. The system can dynamically change its operation mode by adjusting the lamination direction and substrate positioning according to the required panel type. This allows the same apparatus to adapt between E-mode and O-mode manufacturing processes, transforming a static single-mode system into a dynamic multi-mode system
2Productivity
If the manufacturing line is dedicated to producing only one mode of liquid crystal panel, then the production process is simple and efficient, but the versatility of the manufacturing line is limited
Solution Approach 1:
The patent makes the manufacturing line universal by enabling it to produce both E-mode and O-mode liquid crystal panels using the same production line. The system can switch between manufacturing modes by adjusting the lamination direction and panel positioning, thereby eliminating the need for separate dedicated production lines for each mode while maintaining manufacturing efficiency
Solution Approach 2:
The patent applies parameter changes by modifying process parameters such as lamination direction, substrate orientation, and optical film alignment according to the required panel mode. By changing these parameters dynamically during production, the same manufacturing line can efficiently produce different panel types without requiring physical reconfiguration of the entire production line
3Adaptability or versatility
If pivot units are added to reverse panel edge relationships, then multiple types of optical display elements can be manufactured by a single manufacturing line, but the device complexity increases
Solution Approach 1:
The patent applies dynamics by introducing pivot units that can rotate the panel to change its orientation. These pivot units enable the manufacturing line to dynamically adjust panel positioning and edge alignment according to the required lamination direction. By making the panel orientation adjustable through pivoting, the system can switch between E-mode and O-mode manufacturing while using the same production line, thereby increasing flexibility without requiring complete system redesign

AI summary
According to the present invention, a system for manufacturing an optical display element, which manufactures an optical display element by laminating optical films on both planes of a rectangular panel, includes: a panel supply unit supplying the panel; a panel transport unit transporting the supplied panel; a first laminating unit laminating the optical film onto a first plane of the panel in a direction parallel to a panel transport direction; and a second laminating unit laminating the optical film onto a second plane of the panel so that an absorption axis direction of the optical film is orthogonal to the absorption axis direction of the optical film laminated onto the first plane of the panel, in which when a panel supply direction set to be parallel to the panel transport direction between a longitudinal direction of an initial long edge and the longitudinal direction of an initial short edge of the panel supplied by the panel supply unit and a first laminating direction set so as to laminate the optical film onto the first plane of the panel in one of the longitudinal direction of a long edge and the longitudinal direction of a short edge of the panel are previously set as a process condition, the system includes a first pivot unit that pivots the panel to reverse positional relationship of the initial long edge and the initial short edge of the panel to each other when the set panel transfort direction is orthogonal to the first laminating direction.
