Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen output technologies for mobile terminals lack efficient control and management of information transfer between the terminal and external devices, limiting user convenience and performance.
Innovation Solution
A screen output control system and method that allocates window buffers and screen buffers to efficiently manage and output screen data from a mobile terminal to a connected screen output device, enabling direct rendering and composition of screen data for enhanced performance and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If simple screen output is used to transfer content to external device, then connection functionality is provided, but user convenience and perceived value remain limited
Solution Approach 1:
The patent implements multiple screen output modes (mirror mode and extension mode) within a single screen output system, allowing the mobile terminal to adapt to different usage scenarios. The system can function as a simple mirror display or as an extended workspace, providing universal adaptability that enhances both functionality and user convenience without requiring separate systems
2Productivity
If screen data is rendered and written to buffer for connected screen output device, then efficient screen output control is achieved, but system complexity increases
Solution Approach 1:
The patent segments screen data processing into distinct phases: rendering screen data, writing to buffer, and outputting to the connected device. This segmentation allows each phase to be optimized independently, improving overall screen output efficiency while making the complex buffer management process more manageable and controllable
3Reliability
If existing screen output function is used, then basic display capability is provided, but performance and user experience fail to meet expectations
Solution Approach 1:
The patent changes key parameters of the screen output function by implementing different output modes (mirror vs extension) and optimizing the data transfer process through buffer management. These parameter changes transform the basic display capability into a high-performance system that can handle multiple applications and display scenarios simultaneously, significantly improving screen output performance
Data Source
AI summary
A screen output control method and system and a mobile terminal supporting the same are provided. The screen output control system includes a screen output device and a mobile terminal. The screen output device is connected with the mobile terminal so as to output screen data rendered by the mobile terminal. When the screen output device is connected, the mobile terminal renders screen data for the screen output device, writes the rendered screen data to a buffer assigned to the screen output device, and outputs screen data written in the buffer to the screen output device.
