Dual-System Screen Brightness Switching Without Flicker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen brightness adjustment methods are limited to single operating systems, and there is a need for a solution to adjust screen brightness effectively in electronic devices with dual systems.
Innovation Solution
A method for adjusting screen brightness in electronic devices with dual systems by obtaining screen brightness information from the first system before a switch and applying it to the second system, using gradual or abrupt brightness adjustment rules to avoid screen flicker and improve user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If screen brightness is adjusted in dual systems, then brightness consistency across system switches is improved, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by obtaining and storing screen brightness information from the first system before the system switch occurs. This pre-acquired brightness data is then used to configure the second system's screen brightness, ensuring consistent visual experience across system transitions without requiring complex real-time coordination mechanisms.
2Object-affected harmful factors
If gradual brightness adjustment is used, then screen flicker is reduced, but adjustment time increases
Solution Approach 1:
The patent implements dynamics by providing two distinct brightness adjustment modes: gradual adjustment for normal scenarios to minimize screen flicker and user discomfort, and abrupt adjustment for special scenarios where speed is prioritized. The system dynamically selects the appropriate adjustment mode based on specific conditions, allowing flexible trade-off between flicker reduction and adjustment speed.

AI summary
A screen brightness adjustment method, an electronic device, and a storage medium. The method is applied to an electronic device, which includes a first system and a second system. The method includes: obtaining screen brightness information of the first system, where the first system is a system running on the electronic device before a system switch, and the second system is a system running on the electronic device after the system switch; and adjusting screen brightness of the second system based on the screen brightness information of the first system.
