Head Mounted Display Extending Electronic Device Image Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices often face limitations in display area, leading to image cropping or compression when image resolution exceeds display resolution, negatively impacting user experience.
Innovation Solution
A head-mounted display device (HMD) establishes a connection with an electronic device, performs projection transformation on excess image content using three-dimensional coordinates and grayscale values, and displays the transformed content using an image sensor, effectively extending the display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image resolution is increased beyond display resolution, then image quality is improved, but the image cannot be fully displayed and requires cropping or compression
Solution Approach 1:
The patent extends the display from two-dimensional (electronic device screen) to three-dimensional (spatial extension around the device). By projecting excess image content onto surfaces in the three-dimensional space surrounding the electronic device, the system preserves high-resolution image data while distributing it across multiple spatial dimensions, allowing full utilization of high-resolution images without cropping.
2Loss of information
If display area is increased to show full image, then image completeness is improved, but the electronic device's physical display size is limited
Solution Approach 1:
The patent introduces an intermediary projection system that acts as a bridge between the electronic device's limited display and the desired large-area visualization. The projection device serves as a mediator, taking the electronic device's output and extending it to larger spatial dimensions through optical projection, thereby enabling full image display without physically enlarging the electronic device's display area.
3Adaptability or versatility
If image is cropped or compressed to fit display, then display compatibility is improved, but user experience deteriorates
Solution Approach 1:
The patent segments the image display into two parts: the primary display on the electronic device screen and the extended display through projection. This segmentation allows the system to maintain compatibility with the electronic device's native display resolution while simultaneously preserving the full high-resolution image content in the projected extension, thereby achieving both display compatibility and enhanced user experience.

AI summary
This application relates to the communications field, and in particular, to a head mounted display device for extending a display area of an electronic device and a processing method of the head mounted display device. A display of the electronic device displays first content of an image. The image further includes second content that is not displayed on the display of the electronic device. The head mounted display device obtains, by using an image sensor, the first content displayed on the display of the electronic device, performs projection transformation on the second content, and displays the obtained first content and the second content obtained after the projection transformation on the display of the head mounted display device. Therefore, when image resolution of a to-be-displayed image is greater than display resolution of the display of the electronic device, the entire image is clear without needing to be scaled down or cropped.
