Display Panel Driver Layout Between LED Rows for Narrow Bezels
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, which is not in line with the development trend of display panels.
Innovation Solution
The driver circuit, including shift register circuits, is integrated into the display area by positioning them between adjacent light-emitting element rows, allowing for a narrow or frameless design by reducing the width of the non-display area.

Engineering Contradiction Analysis
1Length of moving object
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 and narrow frame design cannot be achieved
Solution Approach 1:
The driver circuit is relocated from the lateral frame areas (horizontal dimension) to the display area (utilizing vertical arrangement between light-emitting element rows). This dimensional shift allows the frame width to be reduced while the driver circuit remains functional within the display region.
Solution Approach 2:
The driver circuit is merged with the display area by positioning it between adjacent light-emitting element rows. This integration eliminates the need for separate frame areas, achieving narrow frame design while maintaining driver circuit functionality.
2Length of moving object
If the driver circuit is integrated into the display area, then the frame width is reduced, but the layout complexity increases
Solution Approach 1:
The driver circuit is divided into multiple stages of shift register circuits that are cascaded and distributed between adjacent light-emitting element rows. This segmentation allows the complex driver circuit functionality to be distributed across multiple smaller units, managing layout complexity while achieving narrow frame design.
Solution Approach 2:
The shift register circuits are arranged in a cascaded configuration that allows dynamic signal propagation through the display area. This dynamic arrangement enables the driver circuit to function effectively within the constrained display area space.
3Area of stationary object
If the driver circuit is placed in the display area, then the screen-to-body ratio increases, but the risk of affecting display quality increases
Solution Approach 1:
The driver circuit is positioned in specific locations between light-emitting element rows rather than uniformly across the display area. This localized placement minimizes interference with light-emitting elements while maintaining driving functionality, preserving display quality.
Solution Approach 2:
The driver circuit acts as an intermediary between the control system and the light-emitting elements, with shift register circuits serving as intermediate stages that process and transmit signals. This intermediary structure allows precise control while minimizing direct interference with the light-emitting elements.
