Screen Widget Brightness Control via Local Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen widget brightness control technologies cannot adjust the brightness of a small screen window in real-time and automatically, leading to unclear content and dazzling issues when the screen brightness is increased for the full screen.
Innovation Solution
A method and apparatus that automatically determine the widget area based on display data and adjust its brightness to a target level, allowing for partial brightness adjustment of the display screen while maintaining the original brightness of other areas, using ambient light information or user input signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the screen brightness is increased for the full screen to improve widget visibility, then the widget content becomes clear, but other screen areas become dazzling and uncomfortable
Solution Approach 1:
The patent divides the display screen into multiple independent brightness control zones, specifically separating the widget area from the rest of the screen. The processing component identifies widget area coordinates from display data and applies brightness adjustment independently to this segmented region, allowing the widget to be bright and visible while keeping other screen areas at comfortable brightness levels.
Solution Approach 2:
The patent implements local brightness quality control by adjusting only the specific widget area's brightness parameters while maintaining different brightness characteristics in other screen regions. The processing component modifies display data to apply targeted brightness enhancement to the widget coordinates, creating localized high brightness where needed without affecting the overall screen comfort.
2Ease of operation
If automatic brightness adjustment is implemented for real-time widget visibility, then user experience improves, but the device complexity increases
Solution Approach 1:
The patent implements self-service automatic brightness control where the processing component automatically identifies widget areas from display data and adjusts brightness without requiring manual user intervention. The system monitors display content, determines widget coordinates, and autonomously applies appropriate brightness adjustments, making the complexity transparent to the user while providing seamless automatic control.
Solution Approach 2:
The patent establishes a feedback loop where the processing component continuously monitors display data to identify widget areas, adjusts brightness based on this identification, and repeats the process in real-time. This closed-loop feedback mechanism enables automatic adaptation to changing widget positions and content while maintaining manageable system complexity through iterative adjustment.

AI summary
Embodiments of the disclosure provide a method and an apparatus for controlling brightness of a screen widget, a terminal and a storage medium. The method includes: obtaining display data; determining a widget area of the screen widget based on the display data, in which the screen widget is configured to display multimedia information in a form of a small window on the display screen; and controlling a brightness of the widget area to be adjusted to a target brightness.
