Segmented Display with Overlapping High and Low Pixel Density Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing HMDs face challenges in achieving high luminance while maintaining low power consumption, as increasing pixel density to improve image quality leads to increased power consumption and difficulty in displaying a 360-degree view.
Innovation Solution
The electronic device incorporates a first display device with a high pixel density and a second display device with a lower pixel density, where the second display device surrounds the first display device, allowing light from the first display to pass through the second display, thereby reducing light loss and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the pixel density of the HMD is increased to display higher-resolution images, then the image quality is improved, but the area occupied by the display portion becomes difficult to increase
Solution Approach 1:
The display is segmented into multiple display portions with different pixel densities. The first display portion has a first pixel density while the second display portion has a second pixel density that is different from the first. This segmentation allows different regions to serve different functions - high resolution for central viewing and lower resolution for peripheral viewing - thereby achieving both high image quality and large display area.
Solution Approach 2:
Different regions of the display are assigned different quality characteristics. The first display portion maintains high pixel density for the central visual field where users focus attention, while the second display portion uses lower pixel density for peripheral areas. This local quality differentiation optimizes the balance between image quality and display area without uniformly compromising resolution across the entire display.
2Illumination intensity
If light emitted from the first display and transmitted through the optical combiner and light emitted from the second display and reflected by the optical combiner are lost, then the luminance decreases, but increasing the luminance increases power consumption
Solution Approach 1:
Instead of using a single high-performance display that suffers from light loss, the invention creates a composite display system where multiple display portions are optically combined. The optical combiner merges the light from the first display portion and the second display portion to form a unified virtual image, effectively copying and combining visual information to achieve high luminance without excessive power consumption.
Solution Approach 2:
The optical combiner merges light paths from multiple display portions to create a combined virtual image. By combining the transmitted light from the first display portion and the reflected light from the second display portion, the system achieves high overall luminance while distributing the power consumption across multiple lower-power display units rather than requiring one high-power unit.

Implementation Method 1
The second display device includes a second display portion. A plurality of first pixels are arranged in the first display portion. A plurality of second pixels are arranged in the second display portion. The first display device overlaps with the second display device. The second display portion is provided to surround at least part of the first display portion in a plan view. An area occupied by each of the first pixels is smaller than an area occupied by each of the second pixels.
