Transparent Display Panel Asymmetric Pixel Circuit Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transparent display panels suffer from a grating effect due to the strip-like arrangement of pixel circuit and transparent regions, resulting in dense dark lines that affect the display effect.
Innovation Solution
The display panel design includes pixel circuit regions arranged to form joining regions with adjacent transparent regions, where the pixel circuit regions are spaced apart to prevent them from forming a continuous row, thereby maximizing the area of transparent regions and reducing the grating effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If pixel circuit regions are arranged in strip shapes in conventional transparent display panels, then the manufacturing and layout are simplified, but grating effect occurs resulting in dense dark lines that affect display quality
Solution Approach 1:
The patent applies asymmetry by changing the pixel circuit region arrangement from conventional symmetric strip patterns to asymmetric configurations where pixel circuit regions of adjacent pixels are offset from each other. This offset arrangement breaks the periodicity that causes grating effect, eliminating dense dark lines while maintaining manufacturing feasibility through systematic layout design.
Solution Approach 2:
The patent resolves the grating effect by transitioning from one-dimensional strip arrangements to two-dimensional offset patterns. By arranging pixel circuit regions in both horizontal and vertical offsets, the design distributes transparency variations across multiple dimensions, preventing the formation of concentrated dark lines that occur in single-dimensional strip arrangements.
2Object-affected harmful factors
If pixel circuit regions are arranged to reduce grating effect, then display quality improves, but the arrangement complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the pixel array into repeating units with specific offset patterns. Instead of complex unique arrangements for each pixel, the design segments the overall structure into manageable modular units that can be systematically repeated, reducing arrangement complexity while maintaining the grating effect reduction benefit.
Solution Approach 2:
The patent uses periodic action by implementing regular offset patterns that repeat across the display panel. The pixel circuit regions follow periodic offset sequences in both horizontal and vertical directions, creating a predictable, manufacturable pattern that reduces grating effect without requiring complex non-repeating arrangements for each pixel.
Data Source
AI summary
The present disclosure provides a display panel including gate lines and data lines disposed on a base substrate. The base substrate is further divided into pixel regions including transparent regions and pixel circuit regions having pixel circuits. The pixel circuit regions of at least two adjacent pixel regions are disposed next to each other and form a pixel circuit joining region, so that the pixel circuit regions of a same row or a same column of the pixel regions are arranged spaced apart from each other. Two adjacent pixel circuit joining regions are spaced apart by the transparent regions.
