Display Interface Power Adjustment via Segmented Luminance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-screen electronic devices consume more power, leading to reduced standby capabilities, and existing methods to reduce power consumption, such as luminance control, negatively impact the displaying effect and user experience.
Innovation Solution
A method and apparatus that adjust the display interface by sampling current values to determine power consumption and automatically adjust the display interface, such as changing wallpaper or colors, to optimize power usage without lowering luminance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If luminance of the screen is reduced to reduce power consumption, then power consumption is reduced, but luminance of the display interface is reduced and user experience is deteriorated
Solution Approach 1:
The patent segments the screen display into two independent controllable parts: the background screen luminance and the foreground display interface luminance. By separating these two elements, the system can reduce power consumption through screen dimming while maintaining interface visibility through local brightness enhancement, thus resolving the contradiction between power savings and display quality.
Solution Approach 2:
The patent applies local quality by enhancing the luminance of the display interface area specifically while reducing the luminance of the background screen area. This localized brightness adjustment ensures that the interface remains clearly visible to users even when the overall screen luminance is reduced for power saving purposes.
2Duration of action of stationary object
If luminance of the screen is reduced to improve standby capability, then standby capability is improved, but displaying effect is affected
Solution Approach 1:
The patent divides the display system into background screen and foreground interface components with independent luminance control. This segmentation allows the background to be dimmed for extended standby duration while the foreground interface maintains sufficient brightness for reliable information display and user interaction.
Solution Approach 2:
By applying local quality enhancement to the display interface region, the patent ensures that critical information and interactive elements remain clearly visible even when the overall screen luminance is reduced to extend standby capability, thus maintaining displaying effect reliability.

AI summary
The present disclosure relates to a method applied to an electronic device with a screen. The screen displays a display interface. In one example method, a current value of a current sampling point is obtained. Based on the current value, whether power consumption of the electronic device meets a criterion is determined. The display interface is adjusted when the power consumption of the electronic device does not meet the criterion.
