Display Panel Circuit Layout for Borderless Narrow-Bezel Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels have a wide border region due to the need to accommodate driving circuits, which limits their ability to achieve a narrow or borderless design.
Innovation Solution
The display panel is designed with first pixel circuits having a smaller size in one direction than second pixel circuits, allowing the driving circuit to overlap with light-emitting elements, thereby reducing the border width and enabling a borderless design by optimizing the arrangement of pixel and driving circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driving circuit is arranged in the border region to accommodate it, then the driving circuit can function properly, but the border width becomes large
Solution Approach 1:
The patent applies dimensionality change by allowing the driving circuit to be arranged in the display area rather than being confined to the border region. The first shift register is positioned to overlap with light-emitting elements in the second direction, transforming the traditional two-dimensional layout constraint into a multi-layered spatial arrangement that reduces border width while maintaining circuit functionality.
Solution Approach 2:
The patent merges the driving circuit with the display area by positioning the first shift register to overlap with light-emitting elements. This integration allows the driving circuit to share space with the display region, eliminating the need for a separate border region and achieving a narrow or borderless design.
2Area of stationary object
If the first pixel circuit has a smaller size than the second pixel circuit, then space is saved for arranging driving circuits, but the pixel circuit design becomes more complex
Solution Approach 1:
The patent applies local quality by designing different pixel circuits (first and second pixel circuits) with different sizes according to their specific functional requirements. The first pixel circuit is optimized for compact arrangement to save space, while the second pixel circuit maintains standard dimensions, allowing each region to have the appropriate characteristics for its purpose.
