Display Apparatus Overlapping Scan Driver and Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face challenges in minimizing dead space while maintaining a sufficient area for wiring, which affects the visibility and efficiency of image display.
Innovation Solution
The display apparatus incorporates a substrate with a display area and a peripheral area, featuring a driver and output wiring configuration where the scan line overlaps the scan driver but not the light emission control driver, and includes a power supply wiring system to optimize the layout and reduce dead space without increasing non-display areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the driver and wiring are arranged in the peripheral area with overlapping configuration, then the dead space is reduced and display area is increased, but the wiring layout complexity increases
Solution Approach 1:
The patent transitions from a planar wiring arrangement to a three-dimensional overlapping configuration where the scan line passes over the upper surface of the scan driver. This vertical stacking in the overlapping region allows more efficient space utilization, reducing dead space while maintaining clear signal transmission paths.
Solution Approach 2:
The patent merges the driver and wiring functions into a compact integrated layout where the scan line overlaps with the scan driver in specific regions. This merging approach eliminates the need for separate dedicated spaces for drivers and wiring, thereby reducing the overall peripheral area and increasing the display area.
2Area of stationary object
If the scan line overlaps the scan driver, then the dead space is minimized, but the signal transmission reliability may be affected
Solution Approach 1:
The patent segments the wiring path into distinct regions: overlapping regions where the scan line passes over the scan driver, and non-overlapping regions where they are separated. This segmentation allows the design to benefit from space efficiency in overlapping areas while maintaining signal reliability in separated areas.
Solution Approach 2:
The patent introduces an insulating layer as an intermediary between the scan line and scan driver in overlapping regions. This insulating layer ensures electrical isolation and prevents signal interference, thereby maintaining transmission reliability while allowing the wiring to overlap with the driver for space efficiency.

AI summary
A display apparatus includes a substrate having a display area and a peripheral area, the peripheral area being outside the display area, a display unit on the display area of the substrate, the display unit including a pixel circuit and a display device electrically connected to the pixel circuit, a driver in the peripheral area of the substrate and configured to provide a signal to the display device, and an output wiring configured to transmit the signal from the driver to the display device, at least a part of the output wiring overlapping the driver.
