Solution Overview
Problem
Existing liquid crystal display panel trace structures cannot input different voltages to panels of varying sizes, leading to poor alignment and suboptimal display quality due to shared common curing pads.
Innovation Solution
A liquid crystal display panel trace structure with a common curing pad, a curing bus, assist curing pads, and curing assist lines allows for the transmission of different common voltages to each panel, using a spare curing pad and spare line to provide unique voltage inputs, optimizing alignment and display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a common curing pad is shared by all panels, then device complexity is reduced, but different voltages cannot be input to panels of different sizes resulting in poor alignment
Solution Approach 1:
The common curing pad is segmented into multiple independent curing pads (first curing pad, second curing pad, third curing pad) that can be independently controlled. Each curing pad can provide different voltages to panels of different sizes, thereby improving alignment quality while maintaining reasonable device complexity through modular design.
Solution Approach 2:
Different regions of the mask are assigned different curing pad configurations tailored to the specific panel sizes at those locations. The first curing pad serves panels requiring higher voltage, while the second and third curing pads serve panels requiring lower voltage,实现ing local optimization of voltage delivery for improved alignment.
2Manufacturing precision
If the mask is modified to accommodate different voltages, then alignment quality improves, but growth duration increases
Solution Approach 1:
The mask is pre-designed with multiple curing pads and their corresponding connection structures before production begins. This preliminary configuration eliminates the need for time-consuming modifications during production, allowing different voltages to be applied to different panels from the start, thereby improving alignment quality without extending growth duration.
3Manufacturing precision
If assist curing pads and curing assist lines are added, then different voltages can be input to each panel improving alignment, but device complexity increases
Solution Approach 1:
The trace structure is segmented into multiple independent voltage delivery paths, with each assist curing pad and curing assist line forming a modular unit. This segmentation allows for precise voltage control to different panels while keeping each module relatively simple, balancing the trade-off between alignment quality and overall device complexity.
