Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing OLED terminal display products suffer from resource wastage and increased architecture costs due to separate signal processing boards and T-Con boards that cannot share resources.
Innovation Solution
A system on chip (SoC) is designed with a shared storage unit for storing image sampling data, display configuration data, and optical compensation data, along with a micro-processing unit, display calibration unit, and image processing unit, allowing for dynamic resource allocation and shared resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate signal processing board and T-Con board are used, then functional requirements are met, but internal resources cannot be shared resulting in resource waste and increased architecture cost
Solution Approach 1:
The patent merges the signal processing board and T-Con board into a single integrated system on chip (SoC). The SoC includes a micro-processing unit for signal processing, a display calibration unit for T-Con functions, and a shared storage unit that both units can access. This integration eliminates the need for separate boards while maintaining all required functions, thereby enabling resource sharing and reducing architectural complexity.
Solution Approach 2:
The shared storage unit in the SoC serves multiple functions: it stores image sampling data for the display calibration unit, stores display configuration data for the image processing unit, and provides optical compensation data. This multi-functional storage component enables both the signal processing board and T-Con board functions to share resources efficiently, resolving the contradiction between adaptability and complexity.
2Quantity of substance
If units are configured according to maximum needs, then functional requirements are satisfied, but internal resources cannot be shared leading to resource waste
Solution Approach 1:
By combining the signal processing board and T-Con board into an integrated SoC with a shared storage unit, the patent enables both units to access and share the same storage resources. This eliminates redundant storage components and allows efficient resource utilization, reducing both the quantity of internal resources needed and the architecture cost.
Solution Approach 2:
The shared storage unit automatically serves both the display calibration unit and the image processing unit without requiring separate storage configurations. The micro-processing unit can dynamically allocate access to the shared storage based on operational needs, enabling self-service resource sharing that optimizes internal resource utilization and reduces manufacturing complexity.
