Multi-Display Frame Insertion for PIP and Unified Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-display systems cannot receive and display multiple images in a picture-in-picture (PIP) mode and lack a method for unified display setting information across multiple devices, requiring separate input of settings for each device.
Innovation Solution
A display device configured as part of a multi-display system that inserts image output information into specific frames of received images and alternately transmits these frames to adjacent devices, using processor-controlled pixel value changes to identify and display images and apply display settings, enabling PIP mode operation and shared settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional multi display system displays only one image sequentially, then the system structure is simple, but the display versatility is limited
Solution Approach 1:
The patent implements periodic action by alternately transmitting frames from multiple images through time-division multiplexing. The processor transmits frames from the first image at predetermined intervals and frames from the second image at other intervals, enabling multiple images to be displayed in a multi-display system without requiring complex hardware modifications to each display device.
Solution Approach 2:
The patent applies segmentation by dividing images into frames and transmitting them at different time intervals. Each display device receives and displays specific frames from different images at different times, creating a picture-in-picture effect where multiple images are effectively displayed simultaneously across the multi-display system.
2Ease of operation
If each display device receives display setting information separately, then the system is easy to implement, but the ease of operation deteriorates
Solution Approach 1:
The patent introduces an intermediary mechanism where the first display device acts as a mediator that receives display setting information from the terminal device and forwards it to the second display device. This allows unified display settings to be applied across multiple display devices without requiring the terminal device to communicate with each display device separately, improving ease of operation.
3Adaptability or versatility
If multiple images are transmitted simultaneously to all display devices, then the display capability is enhanced, but the loss of time increases
Solution Approach 1:
The patent uses periodic action with time-division multiplexing to transmit frames from multiple images alternately through the display chain. By transmitting frames from the first image at predetermined intervals and frames from the second image at other intervals, the system achieves multi-image display capability while minimizing transmission time compared to simultaneous transmission to all devices.

AI summary
A display device configured as a multi display system is provided. The display device includes an input; a display; an output connected to an adjacent display device; and a processor, wherein the processor is configured to control the output to insert image output information into at least one of frames of a first predetermined interval in a first image and frames of a second predetermined interval in a second image when the first image and the second image are received through the input, and to alternately transmit the frames of the first interval and the frames of the second interval to an adjacent display device, and to control the display to display some regions of one of the frames of the first interval and the frames of the second interval based on display layout information.
