Display Device Bezel Reduction via Segmented Pixel Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices have limited display regions due to bezel areas where images are not displayed, leading to reduced screen real estate and aesthetic issues.
Innovation Solution
A display device design that reduces the bezel region by defining adjacent first and second display regions with different pixel structures, including main pixels and sub-pixels, allowing for a curved second display region that integrates with the first display region to enhance aesthetics and reduce non-display areas.

Engineering Contradiction Analysis
1Area of stationary object
If the bezel region is reduced to enlarge the display region, then the display area is increased, but the manufacturing complexity increases due to different pixel structures in different regions
Solution Approach 1:
The display panel is segmented into a first display region with main pixels and a second display region with sub-pixels. This segmentation allows each region to have optimized pixel structures suitable for its specific function, enabling the enlargement of the overall display area while managing complexity through regional differentiation.
Solution Approach 2:
Different pixel structures are applied to different regions of the display panel. The first display region uses main pixels with a first pixel structure, while the second display region uses sub-pixels with a second pixel structure. This local quality approach allows each region to be optimized for its specific requirements, enabling bezel reduction while maintaining manufacturability through region-specific design.
2Area of stationary object
If the bezel region is reduced to enlarge the display region, then the screen real estate is increased, but the manufacturing precision requirements increase
Solution Approach 1:
By segmenting the display into distinct regions with different pixel structures, the manufacturing process can apply specialized precision requirements to each segment. The first display region with main pixels can be manufactured with standard precision, while the second display region with sub-pixels can have tailored manufacturing specifications, thereby managing overall precision requirements while maximizing display area.
Solution Approach 2:
The local quality principle allows different manufacturing precision standards to be applied to different regions. The main pixels in the first display region and sub-pixels in the second display region can have different structural characteristics that are optimized for their respective manufacturing capabilities, enabling large-area display without uniformly high precision requirements across the entire panel.
3Area of stationary object
If different pixel structures are used in different regions, then the display region can be enlarged, but the device complexity increases
Solution Approach 1:
The display panel is divided into a first display region with main pixels and a second display region with sub-pixels, each having different pixel structures. This segmentation enables the use of simplified pixel circuits in the second display region where full functionality is less critical, thereby reducing overall device complexity while still achieving an enlarged display area.
Solution Approach 2:
Different pixel circuit structures are implemented locally in different regions. The main pixels in the first display region use complete pixel circuits for full functionality, while the sub-pixels in the second display region use simplified pixel circuits suitable for their specific application, such as edge display or status indication. This local differentiation reduces the overall complexity of the device by avoiding the need for complex circuits throughout the entire display area.

AI summary
A display device includes a display panel in which a first display region and a second display region adjacent to the first display region are defined. The display panel includes main pixels disposed in the first display region, first sub-pixels disposed in a first sub-region of the second display region, and second sub-pixels disposed in a second sub-region of the second display region and which have a different pixel structure from the main pixels.
