1Object-affected harmful factors
If hardware adjustment technologies are used for eye protection mode, then blue light reduction is achieved, but adaptability to various environments is constrained
Solution Approach 1:
The patent implements dynamic adjustment of color temperature and brightness parameters based on real-time environmental illuminance detection. The system continuously adapts display parameters according to ambient light conditions, transitioning from static hardware adjustments to dynamic software-controlled adjustments that respond to changing environments.
Solution Approach 2:
The patent changes physical parameters of light emission by adjusting color temperature and brightness levels through software control. By modifying these optical parameters dynamically based on environmental conditions, the system achieves adaptive eye protection without being constrained by fixed hardware characteristics.
2Ease of manufacture
If fixed hardware eye protection features are implemented, then manufacturing simplicity is maintained, but fine-grained dynamic adjustment capability is lost
Solution Approach 1:
The patent replaces fixed mechanical/hardware eye protection mechanisms with software-based control systems. Instead of relying on predetermined hardware features, the system uses algorithms to calculate and adjust display parameters dynamically, enabling fine-grained control while maintaining manufacturing simplicity.
Solution Approach 2:
The system performs self-adjustment by automatically detecting environmental illuminance and computing optimal display parameters without user intervention. The eye protection function serves itself by continuously monitoring conditions and adapting parameters, eliminating the need for complex manual configuration or multiple hardware variants.
3Adaptability or versatility
If environmental illuminance detection is added, then adaptive color temperature adjustment is enabled, but device complexity increases
Solution Approach 1:
The patent introduces an illuminance sensor as an intermediary component that bridges the environment and the display system. This single sensor provides the necessary environmental data, which is then processed by software algorithms to determine optimal display parameters, avoiding the need for multiple complex sensing systems.
Solution Approach 2:
The system performs preliminary calculation of display parameters based on detected illuminance values using predetermined algorithms and lookup tables. By pre-computing adjustment strategies and storing them in software, the system reduces real-time computational complexity while maintaining adaptive capability.
