Display Panel Cover Embedded Connection Unit Anti-Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturers face difficulties in analyzing the techniques used for manufacturing and driving display panels without exposing these methods, as existing display devices allow for the separation of covers, enabling unauthorized analysis.
Innovation Solution
A display device design where the connection unit, partially embedded within the cover, disconnects when the cover is separated, preventing signal transmission to the driver unless an external signal is received, thereby maintaining confidentiality of manufacturing techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cover is made separable from the display panel, then ease of manufacture and assembly is improved, but security against unauthorized analysis of manufacturing and driving techniques deteriorates
Solution Approach 1:
The driver is configured to delete stored data before the cover can be separated from the display panel. This preliminary action ensures that even if the cover is removed for analysis, the sensitive manufacturing and driving techniques have already been erased, preventing information exposure while maintaining assembly ease
Solution Approach 2:
The system monitors the separation state between the cover and display panel, and automatically triggers data deletion in the driver when separation is detected. This feedback mechanism links the physical state (cover attachment) to the data protection action, ensuring security without complicating the assembly process
2Ease of operation
If the driver stores data for operation, then functionality is improved, but security against data extraction deteriorates
Solution Approach 1:
The driver automatically deletes stored data when it detects that the cover has been separated from the display panel. This preliminary deletion action occurs before any potential analysis can take place, ensuring that driving techniques and operational data cannot be extracted even though the driver performed its storage function during normal operation
Solution Approach 2:
The cover acts as an intermediary that mediates between the driver's data storage function and security protection. When the cover is properly attached, data can be stored for operation; when separated, it triggers the deletion mechanism, thus protecting the driving techniques while maintaining operational functionality during normal use

AI summary
A display device includes: a display panel including: a display portion for displaying an image; and a first pad coupled with the display portion and for receiving an out signal from the display portion; a driver coupled with the display portion for supplying a driving signal to the display portion; a cover covering the display panel; and a connection unit coupling the first pad and the driver to each other to transmit the out signal to the driver, wherein at least a portion of the connection unit is in the cover.
