Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in reducing the peripheral area to increase the screen-to-body ratio while maintaining high-speed driving and display quality, as the area occupied by drivers is significant.
Innovation Solution
The display device incorporates a first and second display area with light emitting elements, including boundary, copy, and dummy light emitting elements, where the driver is partially positioned in the second display area, allowing for expanded display area and increased screen ratio without compromising display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the driver area is reduced to increase screen-to-body ratio, then the screen-to-body ratio is improved, but the display quality and high-speed driving performance deteriorate
Solution Approach 1:
The patent extends the display area into the peripheral region by placing light emitting elements in the second display area that overlaps with the driver location. This dimensional expansion allows the screen to occupy space previously dedicated to drivers, thereby increasing screen-to-body ratio while maintaining display quality through careful positioning of boundary, copy, and dummy light emitting elements.
Solution Approach 2:
The patent employs copy light emitting elements that replicate the characteristics of boundary light emitting elements, and dummy light emitting elements that simulate active elements. These copied and simulated elements maintain electrical connection patterns and structural configurations that ensure consistent display performance across the expanded area, including regions where the driver is partially disposed.
2Area of stationary object
If the driver area is reduced to increase screen-to-body ratio, then the screen-to-body ratio is improved, but the high-speed driving performance deteriorates
Solution Approach 1:
By extending the display functionality into the peripheral area where the driver is partially disposed, the patent creates additional display regions that can be scanned. The boundary, copy, and dummy light emitting elements are positioned to enable continuous scanning across the expanded display area, maintaining high scan rates while increasing the effective screen area.
Solution Approach 2:
The patent ensures continuous scanning capability across the expanded display area by strategically positioning light emitting elements and maintaining their electrical connections. The copy and dummy elements are configured to be included in the scanning sequence, ensuring uninterrupted high-speed operation across the entire display region including the area overlapping with the driver.
3Area of stationary object
If light emitting elements are disposed in the second display area overlapping the driver, then the display area is expanded, but the device complexity increases
Solution Approach 1:
The patent utilizes the peripheral region and overlaps it with the driver location to create additional display area. By positioning light emitting elements in this overlapping region and establishing their electrical connections through the existing driver structure, the patent expands display area without requiring completely separate driver circuits, thereby managing complexity.
Solution Approach 2:
The driver structure serves dual functions: it drives the traditional display area and simultaneously drives the expanded area including boundary, copy, and dummy light emitting elements. This multi-functionality allows the same driver infrastructure to support the expanded display area, reducing the need for additional complex driving circuits and maintaining relatively simple device architecture.
