A method and smart device for controlling the startup display screen of a smart device

Abstract

The present invention provides a method for controlling the start-up display screen of a smart device and the smart device, which are applied to a smart device that supports video hardware decompression, and specifically include the following steps: the smart device completes the hardware initialization operation, and converts a preset image Store in the first storage area, so that the image layer displays a preset image; start the system kernel, the system kernel controls the video driver module, and start the video layer through the video driver module; read the corresponding preset image conversion in the first storage area It is video data, and the video data is written into the second storage area, so that the video layer displays the video data; the application program entering the system starts. The beneficial effect of the technical solution is that it can realize that the screen of the smart device is turned on to the start-up is completed, and during the whole startup process, the content displayed on the screen of the smart device is seamlessly connected without black screen phenomenon.

Description

technical field [0001] The invention relates to the field of communication technologies, in particular to a method for controlling a startup display screen of a smart device and the smart device. Background technique [0002] Android is a free and open source operating system based on Linux. It is mainly used in mobile devices, such as smart phones and tablet computers. The startup of devices running Android system is generally divided into three stages, which are BootLoader (bootloader) ), kernel (system kernel file) stage of Android, in which, the BootLoader startup stage needs to initialize the CPU, DDR, EMMC and other basic hardware modules of the device, activate the OSD module (image layer), etc., and guide the startup of the Kernel. This stage needs to consume It takes more than 2-3 seconds. The startup phase of Kernel needs to initialize a large number of driver modules. This stage takes more than 5 seconds. Since the startup time of BootLoader and Kernel is short an...

[0002] Android is a free and open source operating system based on Linux. It is mainly used in mobile devices, such as smart phones and tablet computers. The startup of devices running Android system is generally divided into three stages, which are BootLoader (bootloader) ), kernel (system kernel file) stage of Android, in which, the BootLoader startup stage needs to initialize the CPU, DDR, EMMC and other basic hardware modules of the device, activate the OSD module (image layer), etc., and guide the startup of the Kernel. This stage needs to consume It takes more than 2-3 seconds. The startup phase of Kernel needs to initialize a large number of driver modules. This stage takes more than 5 seconds. Since the startup time of BootLoader and Kernel is short and it is single-threaded startup, if you play dynamic Pictures will increase the corresponding start-up time, so usually a static picture is displayed for transition. After entering the Android stage, since multiple threads can be started, animations can be displayed on the screen and will not increase the start-up time. Existing From the Kernel stage to the Android stage, there will be a black screen on the screen during the transition stage between static images and dynamic images, and the display time of this black screen is different on different chip platforms, so it is important for users Bring bad user experience
