Embodiment 1

[0030] Such as figure 1 As shown, this embodiment provides a display method of a terminal, where the terminal includes a first screen and a second screen.

[0031] The dual-screen display in this embodiment specifically refers to: two screens that originally run different applications and display different application data independently are combined into a large screen to jointly display the application data of the same application. For example, the first screen and the second screen are physically spliced ​​to form a large screen, and the size of the large screen is equal to the sum of the size of the first screen and the size of the second screen, and the Chinese chess application is run to make the first screen One screen displays half of the chess board, and the second screen displays the other half of the chess board, so as to achieve the effect of displaying the entire chess board on both screens. Compared with running Chinese chess applications on two screens alone, the...

Embodiment 2

[0061] Such as figure 2 As shown, in this embodiment, the notification is a hot plug event; step S102 specifically includes:

[0062] Step S201: The system kernel sends a hot-plug event to the display synthesis module, the hot-plug event includes an unload message (remove) and a load message (add), wherein the unload message is used to notify other threads of the underlying dynamic The first driver and the second driver are being unloaded, and the loading message is used to notify other threads that the underlying dynamic is loading the third driver;

[0063] Step S202: the display composition module calls a hook function (hook_hotplug) to send the hot plug event to the interface delivery service;

[0064] Step S203: the interface delivery service receives the hot plug event, then calls its callback function hot plug event receiving function (onHotplugReceived) to obtain the screen information of the third screen and sends the hot plug event to Show management services.

Embodiment 3

[0075] Such as image 3 As shown, the terminal 10 provided in this embodiment includes a first screen and a second screen, and further includes:

[0076] The trigger unit 101 is configured to trigger the bottom layer to dynamically unload the first driver of the first screen and the second driver of the second screen if the desktop launcher detects a dual-screen integration instruction, and load and drive the first screen Synthesizing with the second screen and displaying it as a third driver of the third screen;

[0077] The notification unit 102 is used for the system kernel to send a notification to the activity management service through the display synthesis module, the interface delivery service and the display management service;

[0078] The activity stack compositing unit 103 is used for the activity management service to obtain the pre-held activity stack of the first screen and the activity stack of the second screen according to the notification, and combine the a...

Abstract

Embodiments of the invention provide a terminal and a display method thereof. The method comprises the steps of uninstalling drivers of a first screen and a second screen, loading a driver for driving the first screen and the second screen to be synthesized and displayed as a third screen, and sending a corresponding notification; obtaining previously kept activity stacks of the first screen and the second screen according to the notification, and synthesizing the activity stacks of the first screen and the second screen into an activity stack of the third screen; generating screen information of the third screen and a task stack for placing the screen information according to the activity stack of the third screen; and performing windowing calculation on the third screen synthesized by the first screen and the second screen again according to the screen information, generating display windows of the third screen, and sending the display windows to a display synthesis module corresponding to the third screen, thereby enabling the display windows to be synthesized and displayed in the third screen. According to the terminal and the display method provided by the embodiments of the invention, data of any application can be displayed in one screen synthesized by two screens on the premise of not restarting a system, so that the compatibility is good.

Description

technical field [0001] Embodiments of the present invention belong to the field of electronic technology, and in particular relate to a terminal and a display method thereof. Background technique [0002] With the continuous popularization of display technology, there is an increasing demand for displaying data on multiple screens to achieve multi-screen interaction. [0003] However, existing terminals or display devices need to restart the system or only run a specific application written by the terminal or display device manufacturer to display the data of the same application on two screens. The compatibility is poor and any application cannot be realized. dual screen in one display function. Contents of the invention [0004] The embodiment of the present invention provides a terminal and its display method, which can display the data of any application on a screen composed of two screens without restarting the system, and can realize dual Screen in one display func...
