VR Display Device Alternating Pixel Types for Color Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Personal immersive devices for virtual reality suffer from reduced pixel density due to the pentile matrix pixel structure, where some colors are not represented on four unit pixels, leading to decreased color representation when combining left and right eye images.
Innovation Solution
The implementation of a display device with alternating unit pixel types on each display panel, ensuring that all colors are represented by combining left and right eye images, with each unit pixel type on one panel complementing the color absence in adjacent unit pixels on the other panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a pentile matrix pixel structure is used in personal immersive devices, then device complexity is reduced and manufacturing is simplified, but pixel density and color representation are reduced
Solution Approach 1:
The patent transitions from a conventional 2D pixel arrangement to a 3D stereoscopic display architecture with separate left and right eye display panels. Each panel uses a pentile matrix structure, but the combination of both panels creates a complete color representation system, effectively adding a dimensional aspect to resolve the color density limitation.
Solution Approach 2:
The display system is segmented into two independent display panels (left eye and right eye), each with its own pixel array. This segmentation allows each panel to use the simplified pentile structure while the combined output from both panels provides complete color information, resolving the contradiction between manufacturing simplicity and color representation.
2Adaptability or versatility
If the distance between the screen and user's eyes is reduced for immersive experience, then immersion is improved, but pixel density is reduced
Solution Approach 1:
The patent changes the display parameters by implementing a stereoscopic architecture with separate left and right eye panels. This parameter change allows the system to maintain effective pixel density at short viewing distances by providing complete color information through the combination of both panels, even when each individual panel uses a reduced pentile structure.
3Device complexity
If a pentile matrix scheme with four subpixels forming two unit pixels is used, then device complexity is reduced, but color representation completeness is reduced
Solution Approach 1:
The patent merges the output of two separate display panels (left eye and right eye) to create a complete color representation system. Each panel individually uses the simplified pentile structure with incomplete color sets, but when combined, they provide complete RGB color information, resolving the contradiction between reduced complexity and complete color representation.

AI summary
A display device for virtual reality. A first display panel comprises a first pixel row having a first end and a second end that is closer to the second display panel than the first end. The first pixel row has a first arrangement of unit pixels that alternate between a first unit pixel type and a second unit pixel type. A second display panel comprises a second pixel row aligned with the first pixel row and having a third end and a fourth end that is further from the first display panel than the third end. A first unit pixel at the first end of the first pixel row is the first unit pixel type, and a second unit pixel at the third end of the second pixel row is the second unit pixel type.
