Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display module detection devices are limited in applicability as they are adapted to only one type of display screen and touch screen, requiring different initialization codes and time sequences, making them ineffective for multiple types of display modules.
Innovation Solution
A display module detection device with a storage module that pre-stores configuration parameters for various types of display modules, allowing the test system module to select and output appropriate parameters for detection, enabling detection of multiple types without kernel recompilation or image file reinstallation, using a single-chip microprocessor and network interface for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a detection device is designed for a specific type of display module, then the detection precision for that type is improved, but the adaptability to other types deteriorates
Solution Approach 1:
The detection device incorporates a storage module that pre-stores configuration parameters for multiple types of display modules, and a test system module that can select and apply different parameter sets based on the detected module type. This allows a single device to perform specialized detection for multiple different display module types without requiring separate dedicated devices for each type.
Solution Approach 2:
The device changes its operational parameters dynamically by selecting from pre-stored configuration parameter sets corresponding to different display module types. The test system module retrieves appropriate initialization codes, driving frequencies, and timing parameters from the storage module based on the identified module type, enabling the same hardware to adapt its detection characteristics to match different display technologies.
2Measurement precision
If different initialization codes and time sequences are used for different display module types, then the detection precision for each type is improved, but the device complexity increases
Solution Approach 1:
Configuration parameters including initialization codes, driving frequencies, and time sequences for multiple display module types are pre-calculated and stored in the storage module before actual detection operations. When a display module type is identified, the test system module simply retrieves the corresponding pre-prepared parameter set, avoiding the need to compute or configure parameters in real-time and reducing operational complexity.
Solution Approach 2:
The device creates and stores copies of configuration parameter sets for different display module types in the storage module. Instead of developing new detection parameters for each module type, the system uses replicated parameter templates that can be selected and applied, simplifying the management of multiple configuration sets.
3Adaptability or versatility
If the kernel of the test system module is recompiled or image file is reinstalled for each display module type, then the adaptability is improved, but the ease of operation deteriorates
Solution Approach 1:
The system separates the core test system module kernel from the configuration parameters by storing parameters externally in a storage module. This segmentation allows the kernel to remain unchanged while only the parameter data needs to be swapped when changing display module types, eliminating the need to recompile or reinstall the kernel for each type.
