Portable Terminal Display Segmentation for Videophone and Application Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable videophone devices do not effectively utilize high-resolution displays for enhanced communication, lacking technologies that leverage higher pixel densities for improved image quality during video calls.
Innovation Solution
A portable terminal device that utilizes a high-resolution LCD display to simultaneously show videophone and application images, allowing users to switch between screens and transmit application data instead of videophone data during calls, thereby optimizing the use of high-resolution displays for high-quality communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a portable videophone device uses a high-resolution display, then image quality during video calls is improved, but the device cannot simultaneously display application images with detailed information
Solution Approach 1:
The display screen is divided into two independent display regions: a first display region for videophone images and a second display region for application images. This segmentation allows both types of content to be displayed simultaneously without interfering with each other, resolving the contradiction between displaying high-quality videophone images and displaying application information.
2Reliability
If the device transmits only videophone image data, then communication quality is maintained, but detailed information sharing during calls is limited
Solution Approach 1:
The system merges videophone image data transmission with application image data transmission. The image data transmission unit is configured to transmit both the image data captured by the camera and the image data displayed in the second display region simultaneously to the other terminal device, enabling comprehensive information sharing while maintaining communication quality.
3Loss of information
If the device displays application images during video calls, then information sharing is enhanced, but the videophone image display quality may be compromised
Solution Approach 1:
The display is segmented into separate regions for videophone images and application images, allowing both to be displayed simultaneously at full resolution without compromising the quality of either. The image data processing unit processes both types of images independently and transmits them separately, ensuring that application information sharing does not degrade videophone image quality.

AI summary
A portable terminal device for communicating other terminal device includes: a display configured to display an image data; a transmitting unit configured to transmit the image data to the other terminal device; a receiving unit configured to receive a reception image data from the other terminal device; a display control unit configured to allow an application image data to be displayed by a predetermined application program to be displayed on the display and either one of the image data and the reception image data; a selecting unit configured to select either one of the image data and the application image data displayed on the display; and a transmission control unit configured to allow the transmitting unit to transmit the image data or the application image data selected by the selecting unit to the other terminal device.
