TFT Display Module Unique Code Recording Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LCD manufacturing processes cannot uniquely distinguish and track parameters like color for individual LCD modules due to non-unique supplier codes, leading to difficulties in adjustment and increased complexity in marking and data processing.
Innovation Solution
A recording device comprising a management unit, storage unit, and recording unit that generates and writes a unique identification code for each TFT display module, allowing for distinct identification and simplifying the marking process while avoiding errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a supplier code is written into the drive chip to distinguish different suppliers, then the supplier identification is improved, but the ability to uniquely distinguish and track individual LCD modules is lost
Solution Approach 1:
The identification code is segmented into multiple fields: a supplier code field (distinguishing different suppliers) and an individual module code field (uniquely identifying each module). This segmentation allows both supplier identification and individual module tracking to coexist within the same identification system, resolving the contradiction between maintaining supplier identification and enabling unique module distinction.
2Loss of information
If manual marking is performed on each LCD module to enable individual tracking, then the tracking capability is improved, but the appearance quality deteriorates and work complexity increases
Solution Approach 1:
The patent replaces the mechanical manual marking process with an automated electronic code writing system. The recording device automatically writes unique identification codes into the drive chip's code register, eliminating the need for manual marking on the LCD module surface. This substitution maintains individual module tracking capability while eliminating appearance degradation and reducing process complexity.
3Loss of information
If manual marking is performed on each LCD module, then individual tracking is enabled, but the appearance quality and work efficiency deteriorate
Solution Approach 1:
The recording device is designed to automatically perform the identification code writing process without requiring manual intervention for each LCD module. The system self-services by automatically reading module information, generating unique codes, and writing them into the drive chip, thereby enabling individual tracking while maintaining high productivity and avoiding the efficiency loss associated with manual marking.

AI summary
Embodiments of the invention provide a recording device, which comprises a recording unit, a management unit and a storage unit, wherein the management unit is arranged to generate an identification code and write the identification code into the storage unit, the storage unit is arranged to store the identification code, and the recording unit is arranged to read the identification code from the storage unit and record the identification code into TFT display module. The recording device can record the unique code for each TFT display module to uniquely distinguish different TFT display modules, thereby facilitating tracking and adjustment of parameters, such as color and the like, of an installed TFT display terminal. On the other hand, the recording device can simplify a large amount of complex marking work, and guarantee that the TFT display modules would not be identified mistakenly while saving manpower and material resources.
