Solution Overview
Problem
Three-dimensional image display on folding or sliding mobile communication terminals with multiple screens is challenging due to complex hardware and software requirements, particularly in maintaining optimal viewing conditions as the device is opened or closed, leading to difficulties in achieving excellent 3D display effects.
Innovation Solution
A display device with a first and second casing, each having a display screen, equipped with a coupling state detection unit, viewing angle calculation unit, and display control unit to adjust parameters for optimal 3D image display based on the detected coupling state and calculated viewing angle, allowing for seamless transitions between different opening states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If three-dimensional image display is implemented on folding or sliding mobile communication terminals with multiple screens, then diverse display effects can be realized, but the hardware configuration and software processing becomes complex
Solution Approach 1:
The patent uses the camera to capture the actual display screen and transmits the captured image to the other display screen, creating a copy of the display content. This eliminates the need for complex hardware configurations and software processing for multi-screen 3D display, as the system simply captures and reproduces the display output through the camera and communication interface.
2Reliability
If position-detecting sensor is used to detect viewing position and allow three-dimensional image to trace it, then excellent three-dimensional display can be maintained, but the hardware configuration and software processing becomes complex
Solution Approach 1:
Instead of using position-detecting sensors to track viewing position, the patent captures the display screen through the camera and transmits the captured image to the other screen. This copying approach maintains display quality without requiring complex position detection hardware and software processing.
3Adaptability or versatility
If three-dimensional image display is applied to two or more coupled display screens, then more diverse effects can be realized, but additional complex processing is required
Solution Approach 1:
The patent implements multi-screen display effects by capturing the display content through the camera and transmitting the copied image to the other screen. This approach realizes diverse display effects across multiple screens while avoiding additional complex processing requirements, as the system simply reproduces the captured display output.
4Ease of operation
If viewing condition is altered when coupling state between two screens is changed, then portability and operability are improved, but excellent three-dimensional display cannot be maintained
Solution Approach 1:
The patent dynamically adapts the display system by detecting changes in the coupling state between screens and adjusting the camera-based image capture and transmission accordingly. This dynamic approach maintains excellent display quality across different coupling states while preserving the device's portability and operability, as the system automatically adapts to the current configuration without requiring fixed viewing conditions.

AI summary
The mobile communication terminal comprises a first casing and a second casing carrying a first display part and a second display part, respectively. The first display part and the second display part are each capable of 3D display. The controller of the mobile communication terminal detects the mobile communication terminal being opened vertically or horizontally and detects the opening angle between the first casing and the second casing. In the 3D display in the horizontal opened state, the visibility of the 3D display is altered as the opening angle is changed. Therefore, the controller of the mobile communication terminal calculates the viewing angle according to the detected opening angle and changes the parameters for the 3D display, whereby excellent visibility is maintained even if the opening angle is changed.
