Tri-Gate Pixel Layout for Uniform Voltage and High Aperture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The tri-gate pixel structure in display panels experiences uneven voltage distribution, leading to image distortion and reduced pixel opening rates due to the increased number of gate lines, which complicates uniform voltage distribution.
Innovation Solution
A tri-gate pixel structure is designed with parallel gate and data lines intersecting to form sub-pixel areas, where additional electrode lines are placed parallel to the data lines to ensure uniform voltage distribution without increasing the number of gate lines, and these electrode lines are connected to a common electrode layer through via holes to maintain signal integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional pixel structure design is used to ensure uniform voltage distribution, then voltage distribution is improved, but the opening rate of the pixel structure decreases
Solution Approach 1:
The pixel structure is divided into multiple sub-pixel areas, each with its own electrode line configuration. This segmentation allows independent optimization of voltage distribution in each region while maintaining overall high opening rate, as the electrode lines are strategically placed only where needed for voltage uniformity rather than covering the entire pixel area.
Solution Approach 2:
Electrode lines are selectively positioned in specific locations within the pixel structure based on voltage distribution requirements. Rather than uniformly distributing electrodes across the entire pixel area, the design places them locally where voltage non-uniformity occurs, thus achieving voltage uniformity without unnecessarily reducing the overall opening rate.
2Stability of the object's composition
If the number of gate lines is increased in the tri-gate pixel driver structure, then voltage distribution control is improved, but the pixel opening rate decreases
Solution Approach 1:
Instead of adding more gate lines in the horizontal dimension, the invention introduces electrode lines in the vertical dimension running through the pixel structure. This dimensional shift allows voltage control without increasing the number of horizontal gate lines, thereby maintaining high opening rate while achieving voltage distribution control.
Solution Approach 2:
The electrode lines serve multiple functions: they act as voltage distribution pathways, function as additional gating structures, and provide electrical connection between different pixel layers. This multi-functionality allows voltage control without requiring separate dedicated structures for each function, thus avoiding opening rate reduction.
3Stability of the object's composition
If additional electrode lines are added to ensure uniform voltage distribution, then image uniformity is improved, but the complexity of the pixel structure increases
Solution Approach 1:
The electrode lines are merged with existing pixel structure elements such as data lines and gate lines. By combining multiple functions into unified structures, the design achieves improved voltage distribution and image uniformity without proportionally increasing structural complexity, as the electrode lines share space and functions with other existing components.
Solution Approach 2:
The additional electrode lines are designed to serve multiple purposes simultaneously: voltage distribution, signal transmission, and structural support. This multi-functionality means that while the structure does become more complex, the complexity serves multiple functions rather than requiring separate dedicated structures for each function, thus the effective complexity increase is minimized.
