Wire-on-array LCD bezel reduction via segmented conductive wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display apparatuses with a wire-on-array structure face limitations in reducing the bezel width due to the required width of conductive wires, which affects signal resistance and amplitude, hindering thin bezel design advancements.
Innovation Solution
The implementation of a liquid crystal display apparatus with a wire-on-array structure that utilizes two sets of conductive wires with specific width ratios (A-type, B-type, and C-type) alternately arranged between driving IC units, allowing for a reduction in the overall width of the peripheral circuit wires without compromising signal integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the width of the common line J is increased to match the width of the conducting structure T (about 900 micrometers), then the connection reliability to the common electrode is improved, but the bezel width of the liquid crystal display panel increases significantly
Solution Approach 1:
The patent divides the peripheral circuit area into multiple segments by arranging driving IC units at intervals at least one side of the peripheral circuit area. Multiple first conductive-wire sets and second conductive-wire sets are connected alternately between every two driving IC units, segmenting the current path and reducing the required width of individual conductive lines while maintaining connection reliability.
2Length of stationary object
If the width of the conducting line K is reduced to narrow the bezel width, then the bezel width is reduced, but the resistance of the conducting line increases and affects signal rising and amplitude
Solution Approach 1:
The patent segments the conducting line into multiple narrower lines (first conductive-wire sets and second conductive-wire sets) arranged alternately. This segmentation allows each individual line to be narrower (reducing bezel width) while the collective arrangement maintains the required current carrying capacity and signal quality.
Solution Approach 2:
The patent transitions from a single wide conducting line to multiple narrow lines arranged in an alternating pattern across different dimensions. This dimensional rearrangement reduces the width occupied by each line while maintaining the overall electrical performance through the distributed arrangement.
