Display Panel Special-Shaped Region Pixel Density Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels with right-angled designs face challenges in accommodating electronic elements, leading to reduced screen-to-body ratio and increased susceptibility to damage, especially in full-screen mobile phones with special-shaped displays, resulting in non-uniform display brightness and potential breakage.
Innovation Solution
A display panel design with a special-shaped area that includes a first and second display region, where the first sub-display region has a lower pixel density than the second sub-display region, and overlapping regions between scanning and fixed potential signal lines are adjusted to compensate for the loading capacity of scanning signal lines, improving display uniformity and reducing the risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display panel uses a special-shaped display screen to reserve space for components, then the screen-to-body ratio is improved, but the display brightness uniformity deteriorates due to non-uniform scanning signal line loading capacity
Solution Approach 1:
The patent applies local quality by dividing the display region into multiple sub-display regions with different pixel densities. The first sub-display region has a first pixel density while the second sub-display region has a second pixel density that is different from the first. This local differentiation allows the scanning signal lines to have more uniform loading capacity across different regions, improving display brightness uniformity while maintaining the special-shaped display design that increases screen-to-body ratio.
2Measurement precision
If the pixel density is increased to improve display quality, then the display resolution is improved, but the loading capacity difference of scanning signal lines increases leading to non-uniform display brightness
Solution Approach 1:
The patent implements local quality by creating different pixel densities in different sub-display regions. The first sub-display region contains pixels with a first pixel density, while the second sub-display region contains pixels with a second pixel density. This local variation in pixel density compensates for the loading capacity differences of scanning signal lines, ensuring uniform display brightness while maintaining high overall display resolution.
Solution Approach 2:
The patent applies segmentation by dividing the display region into multiple sub-display regions (first sub-display region and second sub-display region) with different pixel densities. This segmentation allows each region to be optimized independently for its specific scanning signal line loading requirements, thereby achieving both high resolution and brightness uniformity across the entire display.
3Area of stationary object
If the scanning signal lines are extended to cover more pixels, then the display area is increased, but the loading capacity of scanning signal lines becomes non-uniform causing display brightness inconsistency
Solution Approach 1:
The patent applies local quality by assigning different pixel densities to different sub-display regions based on their specific scanning signal line loading capacities. The first sub-display region has a first pixel density and the second sub-display region has a second pixel density, which compensates for the extended scanning signal lines and ensures uniform display brightness across the entire increased display area.
