Gate Driver Unit Positioning for Narrow Bezel Display Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display screens with gate driver units at the left and right sides face challenges in achieving a narrow bezel design, which affects the user's viewing experience.
Innovation Solution
A display panel with a gate driver unit positioned at the end of the data lines, allowing for a narrow bezel or bezel-less design by rearranging the gate and data lines and incorporating a switch network with transistors to manage scan and grayscale signals efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the gate driver unit is arranged at the left and right sides of the display panel, then the gate driver unit can be easily fabricated and connected, but the bezel size increases and viewing experience deteriorates
Solution Approach 1:
The gate driver unit is repositioned from the traditional left-right side arrangement to a bottom arrangement, utilizing the vertical dimension instead of horizontal space. This dimensional change allows the driver unit to be located at the end of data lines without increasing the lateral bezel width, thereby improving the display area ratio while maintaining manufacturing feasibility through extended data line connections from the bottom.
2Length of stationary object
If the gate driver unit is positioned at the end of data lines, then the bezel size is reduced and viewing experience is improved, but the data lines become longer and more complex
Solution Approach 1:
The data lines are segmented into multiple independent lines extending from the bottom of the display panel to the gate driver unit. This segmentation allows each data line to be optimized independently for length and routing, reducing the overall complexity compared to a single long data line arrangement. The segmented structure also facilitates easier fabrication and testing of individual line segments.
Data Source
AI summary
A display panel is provided which includes a plurality of gate lines extending in a first direction, a plurality of data lines extending in a second direction substantially perpendicular to the first direction, and a driving circuit. The driving circuit is arranged at an end of the data lines for supplying a scan signal to the gate lines and supplying grayscale signals to the data lines.
