Auxiliary Touch Screen Linked Control for Smartphone Brightness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operation manner of smartphone screens is poor, particularly in switching between active and inactive states and adjusting brightness, which does not meet user requirements effectively.
Innovation Solution
A method and apparatus that utilize a main display screen and an auxiliary display screen, both being touch screens, where the auxiliary screen displays predetermined content and receives operation signals to control the main screen to adjust brightness or switch interfaces, enabling linked operations between the two screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single touch screen is used for all operations, then the device structure remains simple, but the operation manner becomes poor and cannot meet user requirements
Solution Approach 1:
The single touch screen is segmented into two functional areas: a main display screen for primary content and an auxiliary display screen for control operations. This segmentation allows different operation modes while maintaining a unified physical structure, resolving the contradiction between operational quality and structural simplicity.
2Use of energy by moving object
If the screen is in inactive state to save energy, then energy consumption is reduced, but the screen cannot respond to operations except wake-up
Solution Approach 1:
The auxiliary display screen acts as an intermediary that remains active or partially active even when the main display is in inactive state. It receives and processes operation signals, enabling limited functionality during low-power mode while preserving energy, thus resolving the contradiction between energy saving and operational responsiveness.
3Adaptability or versatility
If brightness control is implemented through physical keys or touch operations on the same screen, then the control mechanism is simple, but the operation manner is poor and lacks versatility
Solution Approach 1:
The patent introduces a spatial dimension by adding an auxiliary display screen in a different location or orientation. This allows brightness control and other operations to be performed through the auxiliary screen while the main screen displays content, providing versatile operation modes without significantly increasing control mechanism complexity.

AI summary
A method for controlling a screen and an apparatus using the same are provided in the field of display technology. The screen includes a main display screen and an auxiliary display screen, both of which are touch screens on the same surface. The method includes: displaying a predetermined content on the auxiliary display screen; and receiving a first predetermined operation signal corresponding to the predetermined content and controlling the main display screen to perform a predetermined action according to the first predetermined operation signal, including at least one of adjusting screen brightness and switching an interface. The present disclosure solves the problem of a poor operation manner of a screen of a smartphone in the related art. The disclosure further provides linked operation between the main display screen and the auxiliary display screen, and enriches interactive operation forms.
