Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panel designs face challenges in simultaneously achieving a narrow bezel and reducing signal interference between routings, particularly around light-transmitting holes, which affects overall performance.
Innovation Solution
A display panel design that includes a light-transmitting hole surrounded by a non-display region, with data lines having disconnected segments and gating units, where routings for different control lines are arranged in different layers and partially overlap or are staggered to minimize interference, allowing for time-division voltage jumps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If signal lines are routed around the light-transmitting hole to achieve full screen, then the display area is maximized, but the bezel width cannot be narrowed and signal interference between routings increases
Solution Approach 1:
The patent applies multi-layer routing architecture where different control lines are routed in different layers (first routing layer and second routing layer). This vertical dimensionality allows routings to overlap in the planar view while being physically separated in the vertical dimension, thereby reducing signal interference while maintaining full screen display area.
Solution Approach 2:
The data lines are segmented into first segments and second segments that are disconnected at two sides of the light-transmitting hole. The first routing connects the first segment to the second segment through the non-display region, while the second routing provides an alternative path. This segmentation allows flexible routing that avoids interference while maintaining signal transmission.
2Object-affected harmful factors
If routing paths are optimized to reduce signal interference, then signal quality improves, but the bezel width cannot be narrowed
Solution Approach 1:
By utilizing the vertical dimension through multi-layer routing, the patent achieves compact horizontal arrangement of routings in the non-display region. The first and second routings are arranged in different layers, allowing them to occupy the same horizontal space without increasing bezel width, while maintaining signal isolation through vertical separation.
Solution Approach 2:
The patent merges the routing functions into the non-display region by having both the first routing and second routing pass through this area. The gating units are integrated with the routing structure, combining signal control and routing functions in a compact arrangement that narrows the bezel while managing signal interference.
3Device complexity
If multiple control lines share the same routing path, then the wiring structure is simplified, but signal interference between control lines increases
Solution Approach 1:
The patent implements separate routing paths for different control lines by utilizing different layers. The first control line uses the first routing while the second control line uses the second routing. This layered approach maintains wiring simplicity from a planar perspective while providing physical separation in the vertical dimension to eliminate signal interference.
Solution Approach 2:
The patent applies different routing qualities to different control lines based on their specific requirements. The first routing and second routing are designed with different characteristics suited to their respective control lines, allowing optimized signal transmission for each line while maintaining overall system simplicity.
