Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with insufficient light-controlling structures suffer from poor viewing angles and insufficient emitting uniformity, failing to meet consumer expectations for visual quality and functionality.
Innovation Solution
The electronic device incorporates a light-controlling structure with a substrate and two light-adjusting layers, where the first and second light-adjusting layers have overlapping light-transmitting areas with a defined offset, allowing for enhanced light distribution and improved viewing angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional light-controlling structure is used, then the device structure is simple, but the viewing angle is poor and emitting uniformity is insufficient
Solution Approach 1:
The light-adjusting layer is segmented into multiple light-transmitting areas with different offset distances from the reference position. This segmentation allows different regions to control light transmission independently, improving emitting uniformity across the display while maintaining a relatively simple overall structure.
Solution Approach 2:
Different light-transmitting areas are assigned different local properties through varying offset distances from the reference position. This local differentiation enables precise control of light transmission characteristics in different regions, achieving improved emitting uniformity without requiring complex global structural changes.
2Ease of operation
If a conventional light-controlling structure is used, then the manufacturing process is simple, but the viewing angle convergence is improper
Solution Approach 1:
The light-transmitting areas are arranged asymmetrically with respect to the reference position, with different offset distances in different directions. This asymmetric arrangement enables proper convergence viewing angle characteristics, allowing the display to be viewed correctly from multiple angles while the offset pattern can be integrated into standard manufacturing processes.
3Illumination intensity
If the light-transmitting areas are aligned without offset, then the structure is simple, but the brightness distribution is non-uniform
Solution Approach 1:
The offset arrangement introduces a spatial dimension variation in the light-transmitting area configuration. By varying the offset distance from the reference position across different light-transmitting areas, the patent achieves uniform brightness distribution through dimensional diversification rather than through complex material or structural changes.
