Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
OLED and other display devices with curved lateral sides suffer from light refraction and scattering, which degrade the quality of the displayed image.
Innovation Solution
A display device design featuring a window layer with bent and non-bent areas, where the first display panel is positioned in the bent area and the second display panel in the non-bent area, along with a light blocking layer and drivers positioned in non-display areas to minimize light interference and reduce bezel width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the display device uses a curved lateral side design, then the device achieves a modern aesthetic appearance and compact form factor, but light refraction and scattering occur which degrades image quality
Solution Approach 1:
The display device is segmented into multiple display panels (first display panel, second display panel, third display panel) arranged in specific orientations. This segmentation allows each panel to be positioned strategically to control light paths and prevent refraction issues while maintaining the curved aesthetic appearance.
Solution Approach 2:
Different regions of the display device have different optical properties. The first display area uses a first polarizer with specific orientation while the second display area uses a second polarizer with different orientation. This local differentiation of optical characteristics allows the curved design to maintain image quality by compensating for refraction effects in different zones.

If multiple display panels are arranged to eliminate dead space and reduce bezel width, then the device achieves higher screen-to-body ratio, but the structural complexity increases
Solution Approach 1:
Multiple display panels are merged into a unified display structure with continuous display areas. The first, second, and third display panels are positioned adjacent to each other with their display areas forming a continuous visual field, eliminating dead spaces and reducing the need for extensive bezels while managing complexity through integrated design.
Solution Approach 2:
The display panels are arranged in different orientations (first display panel in first direction, second display panel in second direction, third display panel in third direction) to create a multi-dimensional layout. This dimensional approach allows the device to achieve high screen-to-body ratio by utilizing spatial arrangement rather than simply increasing panel size, thereby managing structural complexity.

If the window layer includes bent areas to accommodate curved display edges, then the device achieves aesthetic appearance, but light refraction occurs at the bent areas affecting image clarity
Solution Approach 1:
The bent area of the window layer is extracted and assigned a specific function: the bent area is positioned to correspond with non-display areas rather than display areas. This extraction separates the aesthetic curved edge function from the image display function, allowing the bent window layer to provide aesthetic appearance while preventing light refraction from degrading image clarity.

AI summary
A display device includes a window layer, a first display panel, and a second display panel. The window layer has at least one bent area adjacent a non-bent area. The first display panel is on a first side of the window layer at a position corresponding to the at least one bent area. The second display panel is on the first side of the window layer at a position corresponding to the non-bent area. The first display panel is in a first display area to display an image, and a first non-display area is adjacent the non-bent area and between the first display area and the non-bent area.
