Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of smartphones and tablet devices with higher definition image displaying and touch sensing functionality leads to increased communication traffic between sub-processors and main controllers, resulting in higher communication time and costs due to the need for more parameters and programs, which is not efficiently managed by current display drivers.
Innovation Solution
A semiconductor device with a bridge circuitry that connects data terminals to both external control devices and non-volatile memory, allowing for efficient serial communication and reducing communication interface requirements by enabling a bridge mode for high-speed access to non-volatile memory, thereby minimizing data transfer time during parameter and program writing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the types and numbers of parameters and program sizes are increased to support higher definition image displaying and touch sensing functionality, then the functionality and performance of the display device are improved, but the communication traffic between the sub-processor and main controller increases, resulting in increased communication time and interface requirements
Solution Approach 1:
The patent extracts the non-volatile memory from the main controller and integrates it directly into the display driver circuit. This allows the sub-processor to access parameters and programs locally without communicating with the main controller, thereby reducing communication traffic and time while maintaining full functionality for high-definition display and touch sensing operations
2Adaptability or versatility
If the types and numbers of parameters and program sizes are increased to support higher definition image displaying and touch sensing functionality, then the functionality and performance of the display device are improved, but the cost to reinforce the communication interface increases
Solution Approach 1:
The patent extracts the non-volatile memory from the main controller and integrates it directly into the display driver circuit. This local integration eliminates the need for enhanced communication interfaces between the sub-processor and main controller, reducing interface complexity and cost while supporting high-definition display and touch sensing functionality
Solution Approach 2:
The display driver circuit is designed to perform multiple functions: it drives the display panel, processes touch sensing signals, and stores parameters and programs locally in its integrated non-volatile memory. This multi-functionality reduces dependency on the main controller and simplifies the overall communication interface requirements
