Display Substrate Aperture Gradient for Brightness Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies face challenges in optimizing brightness and reducing power consumption, particularly in the center region of display panels, due to uniform pixel arrangements that result in unnecessary brightness waste and inefficient power usage.
Innovation Solution
A display substrate design featuring sub pixel units arranged in a specific pattern where the distance and aperture areas of sub pixels vary, with a greater aperture area closer to the midpoint and a smaller one further away, promoting transmittance and brightness while reducing power consumption by optimizing aperture ratios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If uniform aperture areas are used for all sub pixels, then manufacturing is simplified, but brightness uniformity and power efficiency deteriorate
Solution Approach 1:
The patent applies local quality by differentiating aperture areas based on spatial position. Sub pixels in the center region have larger aperture areas to enhance brightness where users focus attention, while sub pixels at the periphery have smaller aperture areas. This creates a gradient distribution that optimizes brightness uniformity and power efficiency according to the visual importance of different display regions.
2Illumination intensity
If larger aperture areas are used in the center region, then brightness is improved, but manufacturing complexity increases
Solution Approach 1:
The patent segments the display panel into multiple regions with different aperture area characteristics. By dividing the sub pixels into center region sub pixels and periphery sub pixels with distinct aperture area ranges, the design achieves optimized brightness distribution while maintaining manageable manufacturing complexity through clear regional classification.
3Use of energy by moving object
If aperture areas are reduced at the periphery, then power consumption is reduced, but brightness uniformity may worsen
Solution Approach 1:
The patent changes the aperture area parameter as a function of position across the display panel. By systematically varying aperture areas from larger values in the center to smaller values at the periphery, the design achieves both power consumption reduction and improved brightness uniformity, as the gradient distribution compensates for the natural luminance fall-off toward the edges.
