Profiled Display Panel Edge Pixel Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low-pixels per inch (PPI) profiled display products, such as vehicle-mounted and outdoor displays, suffer from edge jaggedness and non-smooth transitions due to large pixel units, necessitating a solution to improve edge display quality.
Innovation Solution
A profiled display panel design with a profiled edge area featuring smaller pixel units compared to the regular display area, where the orthographic projection area of pixel units in the profiled edge is smaller and the distance between their centers is less than in the regular area, increasing pixel density and smoothing the edge transition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If pixel units in the profiled edge area are made smaller to increase pixel density, then edge jaggedness is reduced and smoothness is improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies different pixel unit configurations to different regions of the display panel. Specifically, the profiled edge area uses smaller pixel units with reduced orthographic projection areas compared to the regular display area. This local differentiation allows the edge region to achieve higher pixel density and smoother appearance while the main display area maintains standard pixel configurations for cost-effective manufacturing.
Solution Approach 2:
The display panel is segmented into at least two distinct regions: a profiled edge area and a regular display area. Each region is equipped with pixel units optimized for its specific function. The profiled edge area contains smaller pixel units arranged to follow the contour of the profiled edge, while the regular area uses conventional pixel units. This segmentation resolves the contradiction by allowing high precision only where visually critical.
2Manufacturing precision
If pixel density is increased in the profiled edge area by reducing pixel unit size, then edge jaggedness is reduced, but production difficulty increases
Solution Approach 1:
The patent implements local quality optimization by configuring smaller pixel units specifically in the profiled edge area where high pixel density is needed to reduce jaggedness. The regular display area maintains standard pixel unit sizes for easier manufacturing. This localized approach ensures high manufacturing precision only in the visually sensitive edge region while keeping overall production feasible.
3Manufacturing precision
If the orthographic projection area of pixel units is reduced in the profiled display area, then edge smoothness is improved, but pixel manufacturing complexity increases
Solution Approach 1:
The patent applies local quality principles by reducing the orthographic projection area of pixel units only in the profiled display area where edge smoothness is critical. The regular display area continues to use standard-sized pixel units. This selective reduction of pixel unit size in specific regions achieves the desired edge transition smoothness without requiring all pixel units across the entire panel to be manufactured with complex small dimensions.
