Display Device Frame Hiding via Lens-Enlarged Peripheral Pixels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices face limitations in achieving high definition in peripheral areas due to the physical constraints of wiring and sealing materials, making it difficult to hide frames with virtual images effectively, especially when compared to central display areas with higher pixel density and sub-pixel configurations.
Innovation Solution
A display device design that includes a translucent cover with a lens portion over the frame area and a peripheral display area with reduced pixel density, allowing the frame to be hidden by enlarging the image with the lens, thereby relaxing the high-definition limits and increasing the size of the frame that can be concealed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If pixel area is increased to use four or more sub pixels per pixel, then color gamut and power consumption are improved, but pixel density decreases making high definition difficult
Solution Approach 1:
The patent applies different pixel structures to different regions: the central display area uses 4-sub-pixel pixels for high color gamut and low power consumption, while the peripheral display area uses 3-sub-pixel pixels to achieve higher pixel density. This local differentiation resolves the contradiction by allowing each region to optimize for its specific function.
2Manufacturing precision
If pixel size is decreased to achieve high definition, then definition is improved, but area of one pixel is reduced limiting color gamut expansion
Solution Approach 1:
The patent creates a spatial differentiation where the central area maintains larger pixel sizes with 4-sub-pixel structures for color gamut optimization, while the peripheral area uses smaller pixels with 3-sub-pixel structures for high definition. This allows both requirements to coexist in different locations.
3Area of stationary object
If frame area is reduced to achieve frameless design, then aesthetic appearance is improved, but wiring and sealing material constraints make it difficult to maintain display quality
Solution Approach 1:
The patent makes the frame invisible by projecting the peripheral display area onto the frame area through the lens, creating a virtual image that blends the frame with the displayed content. This optical approach allows physical frame reduction while maintaining display quality through the enlarged peripheral area.
Solution Approach 2:
The lens acts as an intermediary that transfers the image from the peripheral display area to the frame area, enabling the frame to serve dual purposes as both a structural element and a display surface, thereby resolving the conflict between frame reduction and display quality maintenance.
4Manufacturing precision
If peripheral display area pixel density is increased to correct image quality deterioration, then image quality is improved, but manufacturing complexity increases
Solution Approach 1:
The patent simplifies manufacturing by using a uniform pixel structure (3-sub-pixel) throughout the entire peripheral display area, avoiding the need for variable pixel densities or complex adaptive structures. The lens handles the enlargement function, separating optical complexity from pixel structure complexity.

AI summary
In the case of a pixel including four and more sub pixels, the area of one pixel is larger than that in the case of a pixel including three sub pixels; therefore, high definition becomes difficult. When a central display area has a structure of four and more sub pixels, in a display device, the pixel structure in a peripheral display area for use in creating a virtual image is reduced to three sub pixels, to allocate the vacant space for high density assignment. Only the pixel density in the vicinity of a frame of a lens portion is compressed, in order to apparently resolve the discord with the image of a non-lens portion. The pixel side in the peripheral display area may be even or gradually narrowed.
