Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light emitting elements are arranged in a two-dimensional configuration, then the light emission coverage and uniformity are improved, but the control complexity and device structure become more complex
Solution Approach 1:
The device is segmented into multiple independent pixel units, each containing transfer elements, setting elements, and light emitting elements. This segmentation allows each pixel to be controlled independently while maintaining a relatively simple individual structure, resolving the contradiction between two-dimensional arrangement and device complexity.
Solution Approach 2:
The patent transitions from one-dimensional sequential control to two-dimensional parallel control by adding setting elements that enable simultaneous activation of multiple pixels. This dimensional change in control architecture allows uniform two-dimensional light emission without proportionally increasing structural complexity.
2Productivity
If multiple light emitting elements are activated simultaneously in parallel, then the productivity and light emission efficiency are improved, but the control mechanism and circuit design become more complex
Solution Approach 1:
Transfer elements are used to preliminarily prepare the conduction state in setting elements before activating light emitting elements. This preliminary action enables parallel control by pre-configuring the circuit paths, allowing multiple pixels to be activated simultaneously without requiring complex real-time control mechanisms.
Solution Approach 2:
Setting elements act as intermediary components between transfer elements and light emitting elements. These intermediaries simplify the control mechanism by providing a clear hierarchical control structure where setting elements mediate the activation signal from transfer elements to light emitting elements, enabling parallel control without excessive complexity.
3Illumination intensity
If transfer elements and setting elements are added to enable parallel control, then the light emission uniformity and parallelism are improved, but the number of components and device area increase
Solution Approach 1:
Multiple functional elements (transfer elements, setting elements, and light emitting elements) are merged into integrated pixel units with shared control lines. This merging approach reduces the overall device area by eliminating redundant components and allowing shared infrastructure among multiple pixels while maintaining parallel control capability.
Solution Approach 2:
Transfer elements and setting elements are designed with multi-functionality to serve multiple pixels simultaneously. A single transfer element can control multiple setting elements, and setting elements can activate multiple light emitting elements, reducing the total number of components needed for two-dimensional parallel control.
