Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in maintaining a high aperture ratio while ensuring better display quality, particularly in high-resolution applications where dark regions can reduce contrast and brightness.
Innovation Solution
The proposed electronic device incorporates a back light module, pixels, a light shielding element, and strategically designed openings. The light shielding element shields at least a portion of the dark regions, and the openings are optimized in size and shape to allow maximum light transmission while minimizing the impact of dark regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the aperture ratio is increased to improve display quality, then the display quality is improved, but the dark regions increase which reduces contrast ratio
Solution Approach 1:
The patent applies local quality by differentiating the treatment of different regions within the pixel aperture. The opening is divided into a light transmission region and a light shielding region, where each region serves a specific function: the light transmission region maximizes aperture ratio and display quality, while the light shielding region eliminates dark regions and improves contrast ratio. This localized differentiation resolves the contradiction between aperture ratio and dark region elimination.
Solution Approach 2:
The patent segments the opening into distinct functional zones: a light transmission region and a light shielding region. The light shielding region is further divided into a first light shielding sub-region and a second light shielding sub-region, each positioned to shield specific dark regions. This segmentation allows simultaneous optimization of both aperture ratio and contrast ratio by assigning different functions to different segments.
2Object-generated harmful factors
If the light shielding element is added to shield dark regions, then the contrast ratio is improved, but the device complexity increases
Solution Approach 1:
The patent merges the light shielding function with the existing pixel structure by integrating the light shielding element into the opening definition. The opening is defined by both a light transmission region and a light shielding region, combining multiple functions (light transmission and dark region shielding) into a single integrated structure. This merging approach improves contrast ratio while minimizing the increase in device complexity.
3Object-generated harmful factors
If the opening size is reduced to minimize dark regions, then the contrast ratio is improved, but the aperture ratio decreases
Solution Approach 1:
The patent applies local quality by differentiating the treatment of different regions within the pixel aperture. The opening is divided into a light transmission region and a light shielding region, where each region serves a specific function: the light transmission region maximizes aperture ratio and display quality, while the light shielding region eliminates dark regions and improves contrast ratio. This localized differentiation resolves the contradiction between aperture ratio and dark region elimination.
