Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional 3D display technology with parallax barrier is used, then 3D display function is achieved, but power consumption increases due to significant light loss
Solution Approach 1:
The backlight source is segmented into multiple light emitting components arranged in alternating patterns (first light emitting components between partition portions, second light emitting components on partition portions). This segmentation allows selective activation of specific light emitting components based on display mode, reducing overall power consumption while maintaining 3D display functionality through controlled light emission patterns.
Solution Approach 2:
Different regions of the backlight source are assigned different functions: first light emitting components are positioned between partition portions to provide light for 3D display, while second light emitting components are positioned on partition portions to reduce crosstalk. This local differentiation optimizes light distribution and reduces energy waste, directly addressing the power consumption issue while preserving 3D display capability.
2Adaptability or versatility
If conventional 3D display technology is used, then parallax barrier-based 3D display is achieved, but light loss increases significantly
Solution Approach 1:
The backlight source is divided into multiple discrete light emitting components with specific spatial arrangements. First light emitting components are placed between partition portions while second light emitting components are placed on partition portions. This segmentation enables precise control of light emission patterns, ensuring light is directed where needed for 3D display while minimizing unnecessary light loss through optimized positioning and selective activation.
Solution Approach 2:
Different functional zones are created within the backlight source structure. The first light emitting components in the regions between partition portions provide primary illumination for 3D display, while second light emitting components on the partition portions address crosstalk issues. This local functional differentiation reduces overall light loss by ensuring each region contributes optimally to the 3D display function.
3Reliability
If light emitting components are arranged to reduce crosstalk, then 3D display quality improves, but device structure becomes more complex
Solution Approach 1:
The backlight source is segmented into first and second light emitting components with distinct positions. First light emitting components are located between partition portions while second light emitting components are located on partition portions. This segmentation systematically addresses crosstalk by spatially separating light emission functions, improving 3D display quality while maintaining a structured, manageable design that doesn't excessively increase complexity.
Solution Approach 2:
The patent combines multiple light emitting components (first and second types) into a single integrated backlight source structure sharing common elements like base substrate, partition layers, and driving circuits. This merging approach achieves crosstalk reduction through differentiated component positioning while avoiding the complexity of entirely separate systems, as both component types work together within a unified structure.
