Pixel Block Overlap Reduces Display Frame Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-display systems, the discontinuity of the display image at frame-shaped non-display portions between display devices leads to a need for narrower frame structures to improve display quality.
Innovation Solution
The configuration of a display device with a main pixel, first and second pixel blocks, and a driver, where the second pixel block is closer to the outer edge than the first pixel block and overlaps the driver, allowing for a narrower frame by extending the display area closer to the seal, and utilizing reflective electrodes and color filters to achieve gradation display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the frame structure is narrowed to improve display quality, then the display area can be extended closer to the seal, but the driver and pixel blocks must be reconfigured to avoid overlapping issues
Solution Approach 1:
The patent extends the display area in the spatial dimension by positioning pixel blocks closer to the seal, while resolving conflicts by utilizing the vertical layering dimension where pixel blocks overlap the driver in planar view but are arranged in different layers, thus narrowing the frame without increasing complexity
Solution Approach 2:
The patent implements a nested configuration where the second pixel block is positioned within the overlapping region of the driver, allowing the display area to extend into the driver's planar footprint without requiring additional space, thus narrowing the frame structure while maintaining functional separation
2Area of stationary object
If pixel blocks are positioned closer to the seal to narrow the frame, then the display area is maximized, but image discontinuity at frame boundaries becomes more visible
Solution Approach 1:
The patent applies local quality by implementing specific electrical connection structures at the boundaries between pixel blocks and the driver, ensuring that the transition region maintains image continuity through careful design of electrode connections and signal routing in the overlapping region
Solution Approach 2:
The patent introduces an intermediary connection structure in the overlapping region between pixel blocks and the driver, which serves as a mediator to ensure smooth image transitions and eliminate discontinuities at frame boundaries while allowing the display area to extend to the seal
3Area of stationary object
If the second pixel block overlaps the driver in planar view, then the frame is narrowed and display area is maximized, but the electrical connection and signal routing become more complex
Solution Approach 1:
The patent segments the electrical connection structure into distinct regions: pixel circuits in the first pixel block, reflective electrodes in the second pixel block, and separate connection pathways that route signals through the overlapping region without interference, managing complexity through modular organization
Solution Approach 2:
The patent resolves electrical connection complexity by transitioning to a three-dimensional arrangement where pixel blocks and the driver overlap in planar view but are separated in the vertical dimension, allowing independent routing of electrical connections without spatial conflict
