Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If a single driving transistor is used to provide driving current to the light emitting component, then the device complexity is low, but the power consumption is high
Solution Approach 1:
The patent divides the driving current path into multiple parallel transistors (first driving transistor and second driving transistor), where each transistor handles a portion of the total driving current. This segmentation reduces the current burden on each individual transistor, thereby reducing the voltage difference across each transistor and lowering overall power consumption while maintaining the required driving capability for the light emitting component.
2Use of energy by stationary object
If multiple parallel driving transistors are used to reduce power consumption, then the power consumption is reduced, but the device complexity increases
Solution Approach 1:
The patent implements segmentation by using multiple parallel transistors to share the driving current load. Each transistor operates with reduced current, which lowers the voltage difference across each transistor and reduces individual power consumption. The parallel configuration allows the system to achieve lower overall power consumption while distributing the current burden across multiple devices.
Solution Approach 2:
The patent merges multiple transistors into a parallel configuration where the first driving transistor and second driving transistor both connect to the light emitting component. This merging of multiple current paths allows the system to distribute the total driving current across multiple devices, reducing the current through each transistor and thereby reducing the voltage difference and power consumption of each individual transistor.
3Use of energy by stationary object
If the voltage difference across a driving transistor is reduced by using multiple parallel transistors, then the power consumption is reduced, but the driving current capability may be compromised
Solution Approach 1:
The patent segments the driving current into multiple parallel paths, where each transistor handles a portion of the total current. This segmentation allows each transistor to operate with a lower voltage difference (reducing power consumption) while the combined output of all transistors maintains the required total driving current capability for the light emitting component.
Solution Approach 2:
The patent combines multiple transistors in parallel to create a unified driving system where the total driving current is the sum of currents from all transistors. This merging approach allows the system to maintain high driving current capability while each individual transistor operates at lower voltage differences, thereby reducing overall power consumption.

AI summary
A driving circuit includes a first driving transistor and a second driving transistor. The first transistor has a first end to receive a power voltage, a control end of the first driving transistor receives a first control signal, and a second end of the first driving transistor is coupled to a light emitting component. The second transistor has a first end to receive a power voltage, a control end of the second driving transistor receives a second control signal, and a second end of the second driving transistor is coupled to the light emitting component. The first transistor provides a first driving current to the light emitting component according to the first control signal, and the second transistor provides a second driving current to the light emitting component according to the second control signal.
