Boot Screen Jumping Elimination via Master-Module Video Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In combined terminal systems, the significant jump between different application interfaces during the power-on process results in a problem of boot screen jumping, as each device has distinct hardware and software, leading to inconsistent and disruptive boot screen displays.
Innovation Solution
Establishing a connection between a master device and module devices for direct video data transmission after video initialization, allowing the master device to display the application interface of the module device once system services are started, thereby avoiding the jump between interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each device displays its own application interface during power-on, then device independence is maintained, but boot screen jumping occurs due to significant differences between interfaces
Solution Approach 1:
The master device acts as an intermediary by receiving video data from module devices and displaying it on its own screen. This mediator approach allows module devices to maintain their interface independence while the master device ensures display consistency, preventing boot screen jumping by centralizing the display function.
2Loss of time
If video data is transmitted after system service startup, then boot time is reduced, but connection establishment must be rapid
Solution Approach 1:
Video initialization is performed in advance during the boot process, before system services fully start. This preliminary action prepares the video transmission infrastructure early, allowing rapid connection establishment when the time comes to transmit video data, thus reducing overall boot time while ensuring reliable connection setup.

AI summary
The disclosure provides a method and device for displaying a boot screen so as to address the problem of boot screen jumping in a power-on process in the prior art. After the first device and second devices complete video initialization, the first device establishes a connection for transmitting video data with prescribed one of the second devices, and after system services of the first device and the second device are started, the first device will display directly video data of an application interface of the prescribed second device, so that only the application interface of the second device will be displayed directly after a startup picture is displayed, thus avoiding a jump between the two home application interfaces of the first device and the second device to thereby solve the problem of boot screen jumping.
