Oblique Gate Line Segmentation for Bezel Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid crystal display apparatuses face challenges in maintaining display quality due to the presence of a significant bezel area, which reduces the perceived display size and affects the overall viewing experience.
Innovation Solution
The display apparatus employs a unique configuration of gate lines that are obliquely inclined and divided into groups, allowing for simultaneous or staggered driving of these lines by gate drivers, which reduces the bezel size and enhances display quality by increasing charging time for pixels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If gate lines are arranged in conventional horizontal/vertical patterns, then the layout is simple and easy to manufacture, but the bezel area becomes large and display quality deteriorates
Solution Approach 1:
The gate lines are divided into two distinct groups: a first gate line group extending in a first direction and a second gate line group extending in a second direction crossing the first direction. This segmentation allows each group to be optimized independently for reducing bezel area while maintaining manageable complexity through systematic organization and driving methods.
Solution Approach 2:
The patent introduces a second directional dimension for gate lines by creating gate lines that extend in directions crossing the first direction. This dimensional change enables more efficient space utilization and reduces the bezel area by optimizing the geometric arrangement of gate lines relative to data lines and pixel electrodes.
2Loss of time
If a single gate driver drives all gate lines sequentially, then the device complexity is low, but the charging time for pixels is insufficient and display quality is poor
Solution Approach 1:
The gate driver is divided into a first gate driver and a second gate driver, with each driver responsible for driving specific groups of gate lines. This segmentation enables parallel driving operations, thereby increasing pixel charging time without proportionally increasing overall system complexity through modular driver design.
Solution Approach 2:
The patent implements overlapping driving periods where the first gate driver and second gate driver operate simultaneously on different gate line groups. This continuous parallel operation maximizes the utilization of driving resources and ensures sufficient charging time for all pixels within the display period.
3Area of stationary object
If gate lines extend only in one direction, then the manufacturing process is simple, but the display area utilization is inefficient and bezel size is large
Solution Approach 1:
Gate lines are segmented into two groups with different extension directions. The first gate line group extends in a first direction while the second gate line group extends in a second direction crossing the first direction. This segmentation enables efficient coverage of the display area and reduction of bezel size while maintaining systematic fabrication processes.
Solution Approach 2:
The patent employs asymmetric gate line arrangements where gate lines in different groups extend in different directions rather than uniformly in one direction. This asymmetric configuration optimizes space utilization and reduces bezel area while the systematic patterning maintains ease of manufacture through standardized fabrication techniques.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively reduces the bezel size and improves display quality by optimizing the driving method of gate lines, leading to enhanced image presentation and user experience.
Implementation Method 1
A voltage is applied to the pixel electrode and the common electrode to form an electric field in the liquid crystal layer. The intensity of the electric field is changed to adjust the transmittance of light passing through the liquid crystal layer to display a desired image.
