Non-Quadrangular Display Device Asymmetric Driving Circuit Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in minimizing dead areas and maximizing the display area, particularly in non-quadrangular shapes, where existing technologies struggle to efficiently arrange driving circuits and signal lines to reduce peripheral space while maintaining effective signal distribution.
Innovation Solution
The display device incorporates a non-quadrangular shape with symmetrical peripheral areas, where first and second sub-driving circuits are alternately arranged in one peripheral area, and third sub-driving circuits are arranged in another, connected to signal lines extending towards the center, with oxide and silicon semiconductor thin film transistors used for efficient signal transmission.

Engineering Contradiction Analysis
1Area of moving object
If driving circuits are arranged in traditional configurations, then signal distribution is maintained, but dead area increases and display area decreases
Solution Approach 1:
The patent applies asymmetry by arranging different types of driving circuits (first, second, and third sub-driving circuits) in different peripheral areas with different configurations. The first and second sub-driving circuits are alternately arranged in the first peripheral area, while the third sub-driving circuits are arranged in the second peripheral area, creating an asymmetric layout that optimizes space utilization and reduces dead area while maintaining signal distribution functionality.
Solution Approach 2:
The patent utilizes the peripheral area dimension by extending signal lines from the center of the display area toward the periphery and arranging driving circuits in the peripheral areas. This dimensional approach allows driving circuits to be positioned outside the main display area, effectively reducing the dead area within the display region while maintaining all necessary signal distribution functions.
2Area of moving object
If peripheral area is reduced, then display area increases, but signal distribution efficiency may worsen
Solution Approach 1:
The patent segments the driving circuits into three distinct types (first, second, and third sub-driving circuits) positioned in different peripheral areas. This segmentation allows each type of driving circuit to be optimally positioned relative to the signal lines it controls, maintaining signal distribution efficiency while minimizing the overall peripheral area required. The alternating arrangement of first and second sub-driving circuits further optimizes this segmented layout.
3Ease of manufacture
If symmetrical peripheral areas are used, then manufacturing is simplified, but dead space increases
Solution Approach 1:
The patent applies local quality by creating asymmetry in specific local areas while maintaining overall symmetry. The first and second peripheral areas are symmetrical to each other, but within these areas, the driving circuits are arranged asymmetrically (alternating first and second sub-driving circuits in the first peripheral area, third sub-driving circuits in the second peripheral area). This local asymmetry reduces dead space while the overall symmetrical structure maintains manufacturing simplicity.
