Double-View Display Device Single-Channel Signal Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current double-view display technology is complex in structure, occupies large space, and is inconvenient to operate due to the need for two independent signal sources and separate processing components, with video signals transmitted through multiple channels.
Innovation Solution
A double-view display device with a display panel and video stream provider that codes and inputs video streams in a single-channel form, using a separation module to split the display into two views, and a comparison module to control the separation process, potentially utilizing a controllable active grating like a twisted nematic liquid crystal cell for image separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two independent signal sources and separate processing components are used for double-view display, then double-view display function is achieved, but the system structure becomes complex and occupies large space
Solution Approach 1:
The patent merges the video stream provider and display panel into an integrated system where the video stream provider directly integrates with the display panel. The processing module combines multiple video streams and outputs them through a single-channel interface to the display panel, eliminating the need for separate processing components and reducing system complexity while maintaining double-view display functionality.
Solution Approach 2:
The display panel is designed with multi-functionality to handle both single-view and double-view display modes. The separation module within the display panel can dynamically separate the displayed picture into two distinct pictures based on the video signal input, allowing the same hardware to serve multiple display purposes without requiring additional dedicated components.
2Adaptability or versatility
If two independent signal sources are used for double-view display, then double-view display is achieved, but the video signal transmission becomes complex
Solution Approach 1:
The patent combines multiple video streams into a single-channel video signal for transmission to the display panel. The processing module multiplexes the video data from multiple sources and transmits it through one unified channel, significantly simplifying the signal transmission architecture while enabling double-view display functionality.
3Ease of manufacture
If separate processing components are positioned outside the signal sources, then video processing is achieved, but the system occupies large space and is inconvenient to operate
Solution Approach 1:
The processing module is integrated within the video stream provider rather than being positioned as a separate external component. This integration consolidates the processing functionality into the existing signal source device, reducing the overall system footprint and improving operational convenience by eliminating the need for separate processing component management.

AI summary
The present invention relates to a display device and a display method. The display device comprises a display panel and a video stream provider, wherein the display panel comprises a display screen and a separation module; the video stream provider provides one or two video streams, the one or two video streams are coded before entering the display screen to form a video signal source, and the video signal source is input to the display screen in a single-channel form; and when the video stream provider provides two video streams, the separation module separates a picture displayed in the display screen into two pictures respectively specific to the two video streams to realize double-view display. In the present invention, the two video streams are provided by the same video stream provider and may be previously coded, so that the complexity of transmission of the video signal source is greatly reduced.
