Dual Display System for Non-Obstructive OSD Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display systems hinder the appreciation of the main image when performing operations like zoom control or keystone correction, as the on-screen display (OSD) images are superimposed on the image being displayed, obstructing the viewer's experience.
Innovation Solution
An image display system comprising a first and second image display device, where the second device displays additional images such as OSD images instead of superimposing them on the main image, allowing the first device to focus on projecting the main image without obstruction, using a see-through HMD with light transmissive properties and wireless communication for seamless information transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If OSD images are superimposed on the main image for display, then operation information can be presented to users, but the main image appreciation is hindered
Solution Approach 1:
The system divides the display function into two separate devices: the first image display device displays only the main image, while the second image display device displays the OSD images. This segmentation allows both functions to operate simultaneously without mutual interference, resolving the contradiction between presenting operation information and maintaining image quality.
Solution Approach 2:
The OSD display function is extracted from the main image display device and transferred to a separate second image display device. This extraction removes the harmful factor (OSD obstruction) from the main image display while preserving the useful function (operation information presentation) in the separated device.
2Object-affected harmful factors
If a second display device is introduced to display OSD images separately, then image appreciation is not hindered, but device complexity increases
Solution Approach 1:
The second image display device serves multiple functions: it displays OSD images, receives user operations, and transmits correction information back to the first device. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in system complexity while achieving the goal of non-obstructive OSD display.
Solution Approach 2:
The system merges the OSD display function with the operation reception function in the second image display device. By combining these functions in a single device rather than using separate components, the system minimizes the increase in complexity while still preventing image appreciation obstruction.

AI summary
An image display system includes a first image display device and a second image display device. The first image display device includes a first communication section adapted to perform communication with the second image display device, a first display section adapted to display a first image based on first image information, a storage section adapted to store second image information, an operation section adapted to receive a first operation, and a control section adapted to make the first communication section transmit the second image information corresponding to the first operation received by the operation section to the second image display device. The second image display device includes a second communication section adapted to perform communication with the first image display device, and a second display section adapted to display a second image based on the second image information received via the second communication section.
