Solution Overview
Problem
The existing AMOLED module determination mechanism for bendable states consumes processing resources of the main control chip, leading to efficiency degradation in determining bending states.
Innovation Solution
An AMOLED module with a bending state sensor and driver chip configuration, where the bending state sensor receives pressure signals and converts them into electrical signals, directly coupled with the driver chip through a flexible printed circuit board, allowing the driver chip to determine and control the display state without relying on the main control chip, utilizing a thin film pressure sensor and resistor for accurate state detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If transmitting and receiving units are equipped in four corners to determine bending state, then bending state determination is achieved, but processing resources of main control chip are consumed and determination efficiency is downgraded
Solution Approach 1:
The patent extracts the bending state determination function from the main control chip and implements it independently in the driver chip. The driver chip directly receives pressure signals from bending state sensors and determines bending states without requiring main control chip intervention, thereby eliminating resource consumption and efficiency degradation while maintaining determination accuracy.
2Adaptability or versatility
If main control chip processes and handles bending state signals, then comprehensive control is achieved, but processing resources are consumed
Solution Approach 1:
The patent segments the control system into two independent functional modules: the driver chip handles bending state determination and display control, while the main control chip manages other system functions. This segmentation allows the driver chip to autonomously process bending state signals, reducing resource consumption and energy usage while maintaining comprehensive control capabilities through modular architecture.
