Mobile Device External Monitor via Direct Frame Buffer Bypass
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies do not effectively allow a mobile device to function as an external monitor for a computing device while simultaneously maintaining its communication capabilities without interrupting the mobile device's own display and input operations.
Innovation Solution
A method where a mobile device receives visual content from a computing device through a physical connection, communicates it directly to its frame buffer, and displays it without using its image processing capabilities, while also receiving and managing communications over its integrated radio, allowing the computing device to control the mobile device's display and input components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the mobile device uses its image processing capabilities to display content from the computing device, then the display quality is improved, but the communication capabilities are interrupted
Solution Approach 1:
The patent segments the display processing function by bypassing the mobile device's image processing capabilities (video card, processor) and directing content directly to the frame buffer. This separation allows the communication radio to operate independently without interference from image processing operations, resolving the contradiction between display quality and communication reliability.
Solution Approach 2:
The patent introduces a direct frame buffer connection as an intermediary pathway between the computing device and the mobile device display. This intermediary bypasses the mobile device's processing pipeline, enabling simultaneous operation of communication functions and display functions without resource conflicts.
2Productivity
If the mobile device processes visual content through its video card, then the content processing capability is improved, but the simultaneous communication reception is blocked
Solution Approach 1:
The patent extracts the content processing function from the mobile device's video card and processor by establishing a direct connection to the frame buffer. This extraction removes the processing bottleneck that was blocking simultaneous communication, allowing the mobile device to maintain both content display and communication reception capabilities.
Solution Approach 2:
The patent enables the mobile device to perform multiple functions simultaneously: displaying content from the computing device, receiving communications via the radio, and maintaining communication capabilities. The direct frame buffer connection facilitates this multi-functionality by eliminating the resource conflict between processing and communication operations.
3Power
If the mobile device uses its processor for image processing, then the visual content processing is improved, but the communication functions are interrupted
Solution Approach 1:
The patent segments the processing workload by eliminating the need for the mobile device's processor to handle image processing tasks. The direct frame buffer connection allows the processor to be freed for communication functions or other tasks, resolving the contradiction between processing power and communication reliability.
Solution Approach 2:
The patent introduces a direct frame buffer pathway as an intermediary that eliminates the processor's involvement in content processing. This intermediary connection allows communication functions to operate independently of the processor, ensuring reliable communication while maintaining visual content display capabilities.

AI summary
A method, system, and medium are provided for using a mobile device (e.g., a smart phone, personal digital assistant (“PDA”), reading device, cell phone) as a external monitor for a computing device (e.g., a laptop, a desktop personal computer). A mobile device may also be used as an input device for the computing device. For example, a trackball, touch screen, keypad, or other input device on the mobile device may be used to control applications operating on the computing device. The mobile device may send and receive communications at the same time a computing device is utilizing the mobile device's input and output components. The mobile device's battery may be charged while the computing device controls the mobile device's input and output mechanisms.
