Display Panel Divided Driving Parts Signal Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As display devices increase in size, the transmission time of driving signals to pixels far from the driver is delayed, leading to inefficiencies, and adding additional drivers on the opposite side increases the bezel size.
Innovation Solution
A display panel with divided driving parts, including connection lines that transmit gate signals efficiently, allowing for reduced transmission times and minimizing bezel size by locating the gate and data drivers on one side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If an additional driver is located on the other side of the display panel, then the signal transmission time is reduced, but the bezel size increases
Solution Approach 1:
The display panel is divided into multiple driving parts, with connection lines (first connection line, second connection line) extending in the first direction to different gate lines. This segmentation allows signals to be transmitted more efficiently to distant pixels without requiring an additional driver on the opposite side, thus reducing transmission time while avoiding increased bezel size.
2Area of stationary object
If the display device size increases, then the display area is expanded, but the signal transmission time to distant pixels increases
Solution Approach 1:
Connection lines extend in the first direction (horizontal dimension) while gate lines extend in the second direction (vertical dimension), creating a two-dimensional routing network. This dimensional approach allows efficient signal distribution across large display areas without increasing transmission time, as signals can travel through the connection lines to reach multiple gate lines simultaneously.
