Wireless Display Mute and Resume Without Reconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies require cumbersome operations to stop and resume image and sound transmission from terminal devices, especially in mobile scenarios, and often necessitate reconnection when wireless communication is disrupted.
Innovation Solution
A display device with integrated circuitry that includes a screen mute icon to instantly stop image and sound output and maintain wireless communication, allowing a separate icon to resume output without reconnection, while disabling touch operations during mute.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device stops image output to conceal information when the user is not actively using the display device, then security is improved, but operational convenience deteriorates because the user must reconnection to resume output
Solution Approach 1:
The display device maintains wireless communication connection in a standby state during periods when image output is stopped. This preliminary action of keeping the connection alive allows for rapid resumption of image output without requiring reconnection procedures, thus resolving the contradiction between security (stopped output) and operational convenience (quick resumption)
2Ease of operation
If the display device continues to receive images from the terminal device while output is stopped, then operational convenience is improved by allowing quick resumption, but energy consumption increases
Solution Approach 1:
Instead of continuously receiving and processing images, the display device adopts a periodic action approach where it maintains the wireless communication connection in a low-power standby state. The device only actively receives and processes images when resumption is requested, thus reducing energy consumption while maintaining operational convenience
3Reliability
If the display device stops image output to conceal information, then security is improved, but loss of time occurs due to reconnection requirements
Solution Approach 1:
The display device performs a preliminary action by maintaining the wireless communication connection in a standby state during periods when image output is stopped. This pre-maintained connection eliminates the need for time-consuming reconnection procedures when the user wants to resume output, thus resolving the contradiction between security (stopped output) and time loss (quick resumption)

AI summary
A display device includes circuitry configured to: receive an image from a terminal device; output the image to a display; acquire an operation with respect to the image displayed on the display; and display a first or second display component with the image on the display. The first display component receives a first operation that stops the output of the image. The second display component receives a second operation that resumes the output of the image to the display. The circuitry is further configured to: in response to an acquisition of the first operation to the first display component, stop the output of the image to the display; continue to receive the image from the terminal device in a case where the output of the image is stopped; and in response to an acquisition of the second operation to the second display component, output the image that has been received.
