Innovation Solution
A display device with a power supply circuit including a display driving component that incorporates a first power supply circuit and a first voltage stabilizing circuit, allowing for two working modes: one mode reduces external power supply capability requirements by sequential conversion, and another mode enhances power supply voltage directly through the stabilizing circuit, thereby optimizing power consumption based on external power supply capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a conventional power supply circuit is used without voltage stabilizing circuit, then the device complexity is reduced, but the power consumption increases and power supply voltage cannot be optimized
Solution Approach 1:
The power supply circuit is designed to operate in two different working modes that can be dynamically switched based on external power supply capabilities. The first working mode uses sequential conversion through power supply circuit and voltage stabilizing circuit when external power supply capability is limited, while the second working mode uses direct connection when external power supply capability is sufficient, optimizing power consumption in each scenario
Solution Approach 2:
The circuit changes its operational parameters by switching between two working modes. In the first mode, the voltage stabilizing circuit generates a first power supply voltage greater than the second power supply voltage from the power supply circuit. In the second mode, the voltage stabilizing circuit directly generates the required voltage from the external power supply, changing the voltage conversion path and reducing power consumption
2Loss of energy
If voltage stabilizing circuit is added to the display driving component, then power consumption is reduced, but the device complexity increases
Solution Approach 1:
The voltage stabilizing circuit is designed with multi-functionality to serve different purposes in different working modes. It can either work in conjunction with the power supply circuit for sequential voltage conversion (first working mode) or directly convert external power supply voltage (second working mode), making the same circuit component adaptable to multiple operational scenarios and reducing overall power consumption
Solution Approach 2:
The system dynamically switches between two operational configurations of the voltage stabilizing circuit. The switching mechanism allows the voltage stabilizing circuit to be connected to different input sources (power supply circuit output or external power supply) based on external power supply capabilities, optimizing energy efficiency while managing device complexity through adaptive operation
3Adaptability or versatility
If external power supply capability requirements are reduced through sequential conversion, then adaptability is improved, but power consumption increases compared to direct voltage generation
Solution Approach 1:
The system dynamically adapts its power conversion path based on external power supply capabilities. When external power supply capability is limited, the system uses sequential conversion through both power supply circuit and voltage stabilizing circuit to reduce adaptability requirements. When external power supply capability is sufficient, the system switches to direct voltage generation mode to minimize power consumption, achieving both adaptability and energy efficiency
