VR Display Smartview Mode Resolution Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
VR display devices experience higher power consumption and resource wastage due to the need to maintain high resolution across all screen regions, including areas not primarily viewed by users.
Innovation Solution
Implementing a smartview mode that adjusts screen resolution dynamically by setting a higher definition in the primary viewing region and a lower definition in secondary regions, with black pixel supplementation in the latter to reduce power usage and maintain image quality in the viewed area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high resolution is maintained across all screen regions, then image quality is improved, but power consumption increases
Solution Approach 1:
The patent applies local quality by differentiating display resolution across different screen regions. The first display region (corresponding to the user's visual field) is rendered at high definition, while the second display region (peripheral areas) is rendered at low definition or completely blacked out. This selective quality assignment maintains excellent image quality in the critical viewing area while dramatically reducing power consumption by minimizing pixel activity in non-visual regions.
Solution Approach 2:
The patent segments the display screen into multiple functional regions: a first display region for high-definition visual content and a second display region for low-definition or blacked-out content. This segmentation allows the system to apply different rendering strategies and power management policies to different parts of the screen, optimizing the balance between image quality and power consumption.
2Measurement precision
If high resolution is maintained across all screen regions, then image quality is improved, but resource wastage increases
Solution Approach 1:
The patent implements local quality by assigning high definition rendering only to the first display region where visual content is actually viewed, while the second display region receives low definition or blacked-out rendering. This eliminates resource wastage by preventing unnecessary high-resolution rendering in areas that do not contribute to the user experience.
Solution Approach 2:
The patent applies partial action by providing high-definition rendering only where necessary (in the visual field region) rather than across the entire screen. The second display region receives minimal or no rendering resources, as full resource allocation there would be excessive and wasteful given that users cannot visually perceive content in those areas.
3Ease of operation
If full screen is displayed at high definition, then viewing experience is improved, but power consumption increases
Solution Approach 1:
The patent applies local quality by concentrating high-definition rendering exclusively in the first display region corresponding to the user's visual field. The second display region is rendered at low definition or completely blacked out. This ensures an excellent viewing experience in the critical area while minimizing power consumption by reducing pixel activity in peripheral regions that do not affect viewing quality.
4Ease of operation
If full screen is displayed at high definition, then viewing experience is improved, but resource wastage increases
Solution Approach 1:
The patent implements local quality by providing high-definition rendering only in the first display region where users actually view content, while the second display region receives minimal rendering resources. This eliminates resource wastage by preventing unnecessary high-resolution processing in areas that do not contribute to the viewing experience.

AI summary
A virtual reality (VR) display device and a display method are provided, so as to improve the problems that an existing VR display device has higher power consumption and waste of resources. The display method for the VR display device includes: in response to a first operation of a user, initiating a smartview mode (S101); controlling display in a first display region of a screen of the VR display device to be at first definition; controlling display in a second display region, other than the first display region, of the screen of the VR display device to be at second definition (S102); and supplementing and displaying black for part of pixels in the second display region (S103); the first display region is a region watched by human eyes; and the first definition is greater than the second definition.
