Concentric Pixel Column Display for Data Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in reducing the amount of processed data while maintaining high-resolution displays, particularly in consideration of human vision, and often have complex internal structures.
Innovation Solution
A display device with concentrically arranged pixel columns, where pixels on the outer side of a reference pixel column have similar shapes obtained by enlarging the reference pixel shape, and the display region is sectioned into areas with equal pixel areas, lengths, and pitches, reducing data processing requirements by varying resolution based on distance from the reference position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the resolution is increased to improve display quality, then the display quality is improved, but the amount of processed data increases
Solution Approach 1:
The patent applies local quality by differentiating pixel densities across different regions of the display. The display unit includes a first region with a first pixel density and a second region with a second pixel density, where the pixel densities are different. This allows high-resolution display in the center region where human vision is most acute while using lower resolution in peripheral regions, thereby reducing the overall amount of processed data while maintaining perceived display quality.
2Quantity of substance
If the pixel density is varied to reduce data processing, then the data processing is reduced, but the display uniformity deteriorates
Solution Approach 1:
The patent implements local quality by creating distinct regions with different pixel densities. The first region has a first pixel density and the second region has a second pixel density, allowing optimized data processing for each region while maintaining overall display functionality. This regional differentiation is justified by human visual perception characteristics.
Solution Approach 2:
The patent segments the display into multiple regions with different pixel density characteristics. The display unit is divided into a first region and a second region, each with distinct pixel density parameters. This segmentation allows independent optimization of data processing requirements for each region, reducing overall data processing burden while maintaining display quality where needed.
3Quantity of substance
If the display region is divided into sections to reduce processing, then the data processing is reduced, but the structural complexity increases
Solution Approach 1:
The patent segments the display into a first region and a second region with different pixel densities. This segmentation enables reduced data processing by treating different regions with different processing requirements, while the segmentation itself is implemented in a way that does not significantly increase structural complexity.
Solution Approach 2:
The patent changes the pixel density parameter across different regions of the display. By varying the pixel density from the first region to the second region, the system reduces the amount of processed data without requiring complex structural changes, as the parameter variation can be managed through software or simple hardware configuration.

AI summary
Provided are a display device and an electronic device that can suppress complication of an internal structure and facilitate effective reduction in an amount of processed data in consideration of human vision in a display region. A display device includes a display unit having a display region in which a plurality of pixel columns is arranged. Each of the plurality of pixel columns has a plurality of pixels arranged in a ring shape. In the display unit, the plurality of pixel columns is concentrically arranged along a plane direction of the display region, around, as a center, a reference position in the display region. In a case where a pixel column arranged at a predetermined position in the plurality of pixel columns is defined as a reference pixel column and a pixel forming the reference pixel column is defined as a reference pixel, a pixel forming a pixel column arranged on an outer side of the reference pixel column has a similar shape obtained by enlarging a shape of the reference pixel.
