Display Device MIMO Antenna Segmentation for Video Audio Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional MIMO communication systems fail to efficiently separate and transfer video and audio communication signals, often using the same channel for both, which limits data transfer rates and introduces latency issues.
Innovation Solution
A display device and communication system that utilize multiple input multiple output (MIMO) communication for video signals and single input single output (SISO) communication for audio signals, with the video signal being received through a subset of antennas and the audio signal through a separate antenna, allowing for higher data transfer rates and reduced latency.

Engineering Contradiction Analysis
1Device complexity
If video and audio communication signals are transferred through the same MIMO communication channel, then device complexity is reduced, but data transfer rate and latency performance deteriorate
Solution Approach 1:
The patent segments the MIMO communication channels by separating video and audio signal transmission. Specifically, it divides the N receiving antennas into two groups: one group (first receiving antenna) dedicated to audio communication signals and another group (second receiving antennas) dedicated to video communication signals. This segmentation allows each signal type to be processed through optimized dedicated channels, improving data transfer rates and reducing latency while maintaining manageable device complexity through structured channel allocation.
2Device complexity
If video and audio communication signals are transferred through the same MIMO communication channel, then channel utilization is simplified, but latency performance deteriorates
Solution Approach 1:
The patent implements segmentation by creating separate communication channels for audio and video signals. The audio communication signal is transmitted through a dedicated channel using the first receiving antenna, while the video communication signal uses a separate channel through the second receiving antennas. This segmentation enables independent optimization of each channel, allowing audio signals to be processed with lower latency requirements while video signals can utilize higher data transfer rates, thereby reducing overall latency without complicating channel management.

AI summary
A display device may include a display panel, N receiving antennas integrated with the display panel, where N is an integer greater than 2, a communication module, and a display driver. The communication module receives a video communication signal using a subset of receiving antennas of the N receiving antennas and an audio communication signal using at least one receiving antenna of the N receiving antennas that is different from the subset of receiving antennas and generates original video data based on the video communication signal and audio data based on the audio communication signal. The display driver receives the original video data from the communication module and drives the display panel based on the original video data.
