Pixel Array Layout Minimizes Non-Display Region
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing resolution of liquid crystal display panels requires more gate and source drivers, leading to a larger non-display region, higher production costs, and wider border lines, which complicates the reduction of these costs and the minimization of the non-display area.
Innovation Solution
A pixel array design featuring first, second, and third signal lines arranged in a specific pattern on a substrate, with pixel structures that include active devices and pixel electrodes, where the pixel electrodes' projections on the substrate are non-overlapping or incompletely overlapping with the second signal lines, reducing coupling effects and allowing for a more efficient layout that minimizes the non-display region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the resolution of liquid crystal display panel is enhanced, then the display quality is improved, but the area of non-display region increases due to increased numbers of gate drivers and source drivers
Solution Approach 1:
The patent combines the functions of gate drivers and source drivers into a single integrated driver located in the non-display region. This integration reduces the total number of separate driver components needed, thereby decreasing the area occupied by the non-display region while maintaining the enhanced resolution capability
Solution Approach 2:
The integrated driver performs multiple functions - serving as both a gate driver and a source driver for different rows of pixel units. This multi-functionality allows a single driver component to control multiple pixel rows, reducing the overall driver count and the associated non-display region area
2Measurement precision
If the numbers of gate drivers and source drivers are increased, then the resolution is improved, but the production cost increases
Solution Approach 1:
By merging multiple driver functions into a single integrated driver, the patent reduces the total component count that needs to be manufactured and assembled. This integration simplifies the manufacturing process and reduces production costs while maintaining high resolution capability
3Measurement precision
If the numbers of gate drivers and source drivers are increased, then the resolution is improved, but the width of border lines increases
Solution Approach 1:
The integration of gate and source drivers into a single compact unit reduces the overall footprint of the driver region. This allows for narrower border lines while maintaining the necessary driver functionality for high resolution displays
4Area of stationary object
If the area of non-display region is reduced, then the display area is increased, but the layout of signal lines and pixel structures becomes more complex
Solution Approach 1:
The patent divides the display region into multiple pixel rows, each controlled by the integrated driver at different time intervals. This segmentation allows the single driver to manage multiple pixel units efficiently, reducing the non-display region area while maintaining manageable layout complexity through systematic organization
Solution Approach 2:
The integrated driver operates by periodically controlling different pixel rows at different time intervals. This periodic operation allows a single driver to sequentially control multiple pixel rows, reducing the need for multiple simultaneous drivers and thereby reducing the non-display region area

AI summary
A pixel array includes multiple first signal lines, multiple second signal lines, multiple third signal lines and multiple pixel structures. The first signal lines are arranged in parallel. The second signal lines are arranged in parallel and intersecting with the first signal lines to demarcate a plurality of first unit regions and a plurality of second unit regions. Each of the second signal lines electrically connects to one of the first signal lines, the second signal lines are arranged in different pitches, and an area of each of the second unit regions is smaller than an area of each of the first unit regions, and the first unit regions and the second unit regions are alternately arranged. An orthographic projection of each of the pixel electrodes on the substrate is non-overlapped with or incompletely overlapped with an orthographic projection of the corresponding second signal lines on the substrate.
