Display Panel Shift-Register Integration for Narrow Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional driver circuit placement on the left and right frames of LED display panels hinders the achievement of a narrow frame design, contradicting the trend towards reduced bezel widths.
Innovation Solution
The shift register circuits in the driver circuit are integrated between adjacent light-emitting element rows within the display area, allowing the driver circuit to be relocated from the non-display area, thereby reducing the frame width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver circuit is located on the left frame and right frame, then the driver circuit can be easily accessed and maintained, but the frame width increases
Solution Approach 1:
The driver circuit is moved from the lateral frame areas (horizontal dimension) to the display area (utilizing vertical arrangement between pixel circuit rows). This dimensional transition allows the driver circuit to be integrated within the display region, reducing frame width while maintaining circuit functionality through cascaded shift register stages positioned between pixel rows.
2Length of stationary object
If the driver circuit is integrated within the display area, then the frame width is reduced, but the layout complexity increases
Solution Approach 1:
The driver circuit is segmented into multiple stages of shift register circuits, with each stage positioned between specific pixel circuit rows. This segmentation distributes the driver circuit functionality across different regions of the display area, managing layout complexity through modular organization while achieving compact integration that reduces frame width.
