Display Device Portrait Mode Mirrored Image Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices fail to correctly recognize and display the orientation of mirrored images during screen sharing services between a personal computer and a rotatable display device, leading to misalignment and user inconvenience.
Innovation Solution
A display device equipped with a wireless communication interface and a controller that determines the display direction of received image signals by recognizing the arrangement direction of character strings, allowing it to display mirrored images in the correct orientation even when the display device is in portrait mode and the image is in portrait direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device operates in portrait mode and receives an image signal from a PC, then the display can be rotated to fit different user scenarios, but the display direction of the mirrored image becomes misaligned and incorrect
Solution Approach 1:
The controller performs preliminary determination of the display direction of the image signal before displaying the mirrored image. By analyzing the arrangement direction of character strings in the received image signal, the controller pre-establishes the correct orientation mapping, ensuring that the mirrored image is displayed in the accurate direction regardless of the display device's posture mode.
2Ease of operation
If the display device automatically recognizes and adjusts the mirrored image direction, then user convenience is improved, but the device complexity increases due to additional control functions
Solution Approach 1:
The display device performs self-service by automatically determining the display direction of the received image signal through analyzing character string arrangement. The controller autonomously identifies whether the image is in portrait or landscape direction and adjusts the mirrored image display accordingly, eliminating the need for manual user intervention while maintaining manageable device complexity through efficient image processing algorithms.

AI summary
A display device comprises a wireless communication interface configured to receive, from a terminal, an image signal corresponding to a source image which is being displayed by the terminal, a display configured to operate in a landscape posture mode or a portrait posture mode, and a controller configured to determine a display direction of the received image signal when the display operates in the portrait posture mode and to display a mirrored image in a portrait direction on the display based on the image signal when the display direction of the image signal is a portrait direction.
