Remote Second Display via Optical Telemetry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual display setups for personal computers are limited by the need for video cables, restricting the mobility and convenience of a second display, especially when used by multiple observers who need to view the same content from a distance or in different locations.
Innovation Solution
A computer system that transmits video signals to a second display via telemetry, eliminating the need for physical cables, allowing the second display to be detached and moved freely while maintaining synchronized content with the primary display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a video cable is used to connect the second display to the computer, then the video signal transmission is stable and reliable, but the mobility and freedom of movement of the second display is limited
Solution Approach 1:
The patent replaces the mechanical cable connection system with an optical wireless transmission system. The video signal is converted to optical form and transmitted through the air to the second display, eliminating the physical cable constraint while maintaining signal transmission. This substitution resolves the contradiction by providing both reliability through established optical communication protocols and mobility by removing the mechanical tether.
Solution Approach 2:
The patent introduces an optical wireless communication intermediary between the computer and the second display. Instead of direct cable connection, the video signal passes through an optical transmission medium (air) and is received by an optical receiver at the display. This intermediary enables signal transmission without physical cable attachment, simultaneously achieving reliability through the intermediary's signal processing capabilities and mobility through wireless operation.
2Ease of operation
If the second display is detached from the computer, then the freedom of movement and convenience for multiple observers is improved, but the video signal transmission becomes more complex
Solution Approach 1:
The patent replaces the simple mechanical cable connection with an optical wireless transmission system. While this increases device complexity by introducing optical transmitters and receivers, it enables complete detachment and freedom of movement. The complexity is justified and managed through the use of standardized optical communication components that maintain signal transmission reliability without requiring complex custom solutions.
3Device complexity
If a cable connection is used for the second display, then the device complexity is low, but the adaptability and versatility of the display system is reduced
Solution Approach 1:
The patent substitutes the simple cable connection with an optical wireless system, which inherently provides greater adaptability. The wireless optical connection allows the second display to be positioned anywhere within transmission range, enabling versatile configurations for multiple observers and different viewing locations. This substitution trades increased device complexity for significantly enhanced adaptability and versatility.

AI summary
A personal computer provides a video signal to dual first and second displays, the second display remote from the computer receiving its video signal by telemetry instead of through a video cable. A video signal transmitter connects to the computer through a transmitter cable plugged into a computer display port. The cable from the second display that would otherwise be plugged into the computer video port is instead connected to a video signal receiver. The signal is then transmitted from the computer by the connected transmitter to the receiver connected to the second display. The second display may detachably mount to the back of the first display.
