OLED Panel Mounting Holes and Notches for High-Accuracy Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display device mounting structures face challenges in achieving high accuracy due to reliance on cutting accuracy of the display device profile, leading to errors and increased complexity and cost, particularly in LCD and OLED devices.
Innovation Solution
Forming mounting holes and notched portions on the display device itself allows for precise positioning and alignment with the casing, using the display device as the reference point, simplifying the mounting process and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If mounting structures use the display device profile as the positioning reference, then the mounting process is simple, but the mounting accuracy deteriorates due to cutting accuracy errors
Solution Approach 1:
The patent divides the mounting reference system into two independent parts: the display device profile and the mounting reference marks. By segmenting the reference system, the mounting accuracy is no longer dependent on the cutting accuracy of the display device profile, thus resolving the contradiction between simple mounting process and high mounting accuracy.
Solution Approach 2:
The patent introduces mounting reference marks as an intermediary element that mediates between the display device and the mounting process. These marks serve as a stable reference that is independent of the display device profile cutting accuracy, enabling high precision mounting while maintaining process simplicity.
2Manufacturing precision
If additional positioning mechanisms are added to improve mounting accuracy, then the mounting precision improves, but the device complexity increases
Solution Approach 1:
The mounting reference marks serve multiple functions: they provide positioning reference, alignment reference, and mounting reference simultaneously. This multi-functionality eliminates the need for additional positioning mechanisms, achieving high mounting accuracy without increasing device complexity.
Solution Approach 2:
The display device itself provides the mounting reference through the mounting reference marks that are integrated into its structure. This self-service approach eliminates the need for external positioning mechanisms, resolving the contradiction between mounting accuracy and structure complexity.
3Manufacturing precision
If complex positioning mechanisms are used to achieve high mounting accuracy, then the mounting precision improves, but the manufacturing cost increases
Solution Approach 1:
The mounting reference marks are simple, inexpensive features that can be easily formed during the display device manufacturing process. These simple reference marks replace complex and expensive positioning mechanisms, achieving high mounting accuracy while reducing manufacturing cost.

AI summary
The present invention provides a display device which can realize the positioning with high accuracy in mounting a display panel to a casing. Further, the present invention provides a display device which can simplify the mounting structure of a display panel and can mount and fix the display panel to a casing easily and with high accuracy. A pair of mounting holes are formed in both ends of a peripheral portion along one side of an OLED panel which performs an image display. By allowing fixing members to pass through the pair of mounting holes, the OLED panel per se becomes the mounting reference and is positioned with respect to the casing with high accuracy. Further, by forming notched portions on another side of the OLED panel which faces one side of the OLED panel in an opposed manner, the OLED panel is supported on a plurality of points and hence, the OLED panel is positioned and fixed with high accuracy.
