Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If progressive displaying is used, then the display device can perform sequential scanning and light emitting, but it cannot perform simultaneous displaying
Solution Approach 1:
The light emitting driving unit is designed to perform multiple functions: it can operate independently to enable progressive displaying, or work in conjunction with the light emitting switch unit to enable simultaneous displaying. This multi-functionality allows a single device to support both displaying modes without requiring completely separate driving circuits, thus improving versatility while controlling complexity.
Solution Approach 2:
The driving system is segmented into two independent functional units: the light emitting driving unit and the light emitting switch unit. The light emitting driving unit handles the progressive scanning control, while the light emitting switch unit handles the simultaneous light emission control. This segmentation allows each unit to be optimized for its specific function while working together to provide both displaying modes.
2Adaptability or versatility
If only progressive displaying is implemented, then the device structure remains simple, but the display device fails to satisfy the demand for diversification
Solution Approach 1:
The patent merges the progressive displaying functionality and simultaneous displaying functionality into a single integrated system. The light emitting driving unit and light emitting switch unit are combined to work together, allowing the display device to switch between progressive and simultaneous displaying modes based on different signal configurations, thus achieving diversity without requiring completely separate systems.
Solution Approach 2:
The display device incorporates dynamic switching capability between different displaying modes. The control system can dynamically adjust which unit (light emitting driving unit or light emitting switch unit) is active based on the desired displaying mode, allowing the device to adapt its behavior dynamically rather than being fixed to a single mode.

AI summary
A display device includes a pixel array, a scan driving unit, a light emitting driving unit and a light emitting switch unit. The scan driving unit is configured to provide a scan signal to the pixel array, the light emitting driving unit is configured to provide a light emitting signal to the pixel array, and the light emitting switch unit is configured to provide a switch signal to the pixel array, wherein the display device performs a progressive displaying when the light emitting driving unit is enabled and performs a simultaneous displaying when the light emitting switch unit is enabled.
