Display Panel Flashlight Effect for Subject Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display monitors struggle to effectively render video streams with oversaturated black image composition, making it difficult for viewers to focus on subjects within the image.
Innovation Solution
A display monitor equipped with an embedded processor, a display panel, and non-volatile memory that receives an enable signal to adjust the display panel, applying a 'flashlight' effect by increasing backlight or adjusting color attributes in a user-selected or metadata-defined area of interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display monitor uses oversaturated black image composition, then the visual impact and contrast are improved, but the visibility of subjects within the image deteriorates
Solution Approach 1:
The patent applies local quality by enabling different brightness levels in different regions of the display panel. The processor selectively adjusts the backlight intensity or pixel brightness for specific areas (e.g., area of interest) while maintaining the original oversaturated black composition in other regions. This allows the subject in the selected area to become visible without compromising the overall visual impact and contrast of the image composition.
2Loss of information
If the display monitor applies a flashlight effect to illuminate specific areas, then the subject visibility is improved, but the device complexity increases
Solution Approach 1:
The patent implements self-service by allowing the user to directly interact with the display panel to define the area of interest. When the user touches or selects a region on the screen, the processor automatically applies the flashlight effect to that selected area without requiring manual configuration of complex parameters. The system serves itself by using the user's selection as the sole input needed to trigger the appropriate display adjustment.

AI summary
In an example implementation according to aspects of the present disclosure, a display monitor comprising a display panel, an embedded processor and a non-volatile memory. The non-volatile memory hosts instructions for the embedded processor to receive an enable signal corresponding to an onscreen display input and adjust an area of the display panel corresponding to a user selection.
