Display Layout with Area-Separated Pixel Circuits for Reduced Dead Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices have dead spaces due to design reasons, such as areas occupied by circuit components and electronic elements, reducing the effective image output area.
Innovation Solution
The display device is designed with a substrate having distinct areas for pixel circuits and display elements, where pixel circuits in one area are connected to display elements in another area through extended electrodes and contact metal layers, allowing for increased pixel circuit density and expanded display area.

Engineering Contradiction Analysis
1Area of moving object
If pixel circuits and display elements are arranged in the same area, then the device structure is simple, but the image output area is reduced due to dead spaces
Solution Approach 1:
The substrate is divided into a first area for pixel circuits and a second area for display elements, spatially separating the two functional components to eliminate dead spaces and maximize the image output area
Solution Approach 2:
The pixel electrode of the second display element extends from the second area to the first area, utilizing the spatial dimension to connect separated components and achieve both area maximization and functional integration
2Quantity of substance
If pixel circuits are densely packed to increase circuit density, then more circuits can be accommodated, but the distance between circuits increases
Solution Approach 1:
By separating pixel circuits into a dedicated first area, the layout can be optimized for density without being constrained by display element positioning, allowing closer spacing and higher circuit integration
