Electrophoretic Display Driver via Network API
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in developing electrophoretic display devices is to drive the electrophoretic display panel smoothly while reducing the size of the end product, as the amount of information that can be loaded on smaller chips decreases with the trend towards smaller devices.
Innovation Solution
An electrophoretic display device comprising an electrophoretic display panel, a network module, a processor, and an electrophoretic display driver, where the processor receives an image information packet via a web application programming interface (API) to operate the driver, allowing the panel to be driven without the need for the processor to store drive setting values and voltage waveform information, thereby reducing its size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the processor stores driver information including setting values and driving methods, then the electrophoretic display panel can be driven smoothly, but the processor size increases
Solution Approach 1:
The patent extracts driver information (setting values and driving methods) from the processor and stores it externally in a driver information storage unit. The processor only retains the function to access and execute this information, significantly reducing its size while maintaining the capability to drive the electrophoretic display panel smoothly.
Solution Approach 2:
The patent introduces a driver information storage unit as an intermediary between the processor and the electrophoretic display panel. This mediator holds the detailed driver information, allowing the processor to remain small while still providing complete driving control through the intermediary layer.
2Volume of moving object
If the processor size is reduced to minimize end product volume, then the device becomes more compact, but the amount of driver information that can be loaded decreases
Solution Approach 1:
The patent moves driver information storage from the one-dimensional constraint of processor memory to an external two-dimensional storage space. This dimensional transition allows substantial driver information to be stored outside the processor, enabling small processor size while maintaining full driver information capacity.
Solution Approach 2:
The patent extracts driver information from the processor's internal memory and places it in an external driver information storage unit. This extraction resolves the contradiction by separating the information storage function from the processor, allowing the processor to remain small while accommodating all necessary driver information externally.
