Display Device Layered Transparency Control for Video Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices interrupt the viewing of content videos when executing or terminating applications or menus, making it impossible to view content videos alongside alarm information, IoT device status, or channel information.
Innovation Solution
A display device with a controller that plays a first content image on a first layer and adjusts the transparency of a second layer based on user input from a remote control device, allowing seamless switching between real-time broadcasting video and application execution video.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If application or menu is executed on the display device, then additional information can be provided, but the viewing of content video is interrupted
Solution Approach 1:
The display screen is divided into multiple layers: a first layer for content video and a second layer for application information. This segmentation allows both content video and application functions to coexist without interruption, as each operates on its own layer independently.
Solution Approach 2:
The application information display is nested within the content video display area. The second layer (application) is positioned above the first layer (content video) in a layered structure, allowing application information to be overlaid on top of the continuing video content without blocking the entire screen.
2Loss of information
If application information is displayed on the screen, then user can check additional information, but the transparency of display screen is reduced
Solution Approach 1:
The transparency of the second layer (application information) is made dynamically adjustable through user input. Users can interact with the display to modify the transparency level, allowing them to balance information accessibility with display clarity according to their needs.
Solution Approach 2:
The transparency parameter of the second layer can be changed based on user input signals. This allows the display to adapt the transparency level dynamically, providing flexibility in how much application information is visible versus how clear the underlying content video remains.

AI summary
According to an embodiment of the present invention, a display device can comprise a display; a user input interface configured to receive signals from a remote control device; and a controller configured to: play a first content image on a first layer of the display, when a trigger for adjusting a transparency of a second layer higher than the first layer is occurred, activate a function of adjusting the transparency of the second layer according to the trigger, receive an input signal for adjusting the transparency of the second layer from the remote control device, and adjust the transparency of the second layer playing a second content according to the input signal.
