Solution Overview
Problem
Flexible display devices face issues with power wastage and user experience degradation due to inability to automatically turn off when bent or folded, and manual on/off operations are not intelligent.
Innovation Solution
A flexible display device with an infrared transmitting circuit and a control circuit that automatically turns the display on or off based on infrared light reception, allowing for intelligent state switching between folded and unfolded states, using a substrate with an anode and infrared receiving circuit, and optionally including multiple infrared light-emitting diodes and photoelectric diodes for reflected light detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the flexible display screen is manually turned off when folded, then power can be saved, but user experience is degraded due to non-intelligent operation
Solution Approach 1:
The display device automatically detects its folded state through infrared receiving circuits and control circuits, then self-regulates the display turning off without requiring manual user input. This self-service mechanism resolves the contradiction by eliminating the need for intelligent manual operation while achieving power savings.
Solution Approach 2:
The system uses infrared transmitting and receiving circuits to detect the folded state of the display, providing feedback to the control circuit which then automatically turns off the display. This feedback loop enables automatic power management that improves user experience while saving energy.
2Ease of operation
If the display remains on when folded, then user experience is maintained, but power is wasted
Solution Approach 1:
The display device automatically detects its folded state through infrared receiving circuits and control circuits, then self-regulates the display turning off without requiring manual user input. This self-service mechanism resolves the contradiction by eliminating the need for intelligent manual operation while achieving power savings.
Solution Approach 2:
The system uses infrared transmitting and receiving circuits to detect the folded state of the display, providing feedback to the control circuit which then automatically turns off the display. This feedback loop enables automatic power management that improves user experience while saving energy.
3Use of energy by moving object
If manual on/off operations are required, then power can be controlled, but the device lacks intelligence
Solution Approach 1:
The system uses infrared transmitting and receiving circuits to detect the folded state of the display, providing feedback to the control circuit which then automatically turns off the display. This feedback loop enables automatic power management that improves user experience while saving energy.
Solution Approach 2:
The patent replaces manual mechanical switching operations with an automated optical detection system using infrared transmitting and receiving circuits. This substitution increases device intelligence by using optical fields to detect state changes and automatically control power, eliminating the need for manual intervention.
