Problems solved by technology

Therefore, as can be seen from the above description, although this invention can realize dual-screen display and video switching on the android platform, and can realize different content displayed on the two screens, it needs to realize two software framework codes with the same function, which undoubtedly increases The amount of system code is reduced, which increases the subsequent maintenance workload of the product. At the same time, the two displays use two softwares to refresh the screen respectively, which consumes a lot of system resources.

Embodiment Construction

[0029] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0030] The present invention jumps out of the shackles of the existing conventional methods. In the dual-screen display method based on the Android platform, based on the overlay superposition mechanism, the main display area used for graphics system output and the superimposed display area used for video output are mixed and superimposed, and finally Presented on the screen, it supports the use of two LCD displays with different resolutions at the same time, and supports the switching display of video between the two displays, and supports automatic full-screen switching in a way that the video display ratio is not distorted.

[0031] As a specific example, the technical solution of the present invention is specifically described by taking the application to a vehicle-mounted terminal as an example.

[0032] The system described in the dual-screen d...

Abstract

The invention discloses an Android platform based double-screen display method. The method is used for switching display between a first display screen and a second display screen and comprises the steps that step1, a Display Hardware object describing the display screens is created in the system, and the Display Hardware object is initialized, wherein three modules of Gralloc, Overlay and OpenGLES are initialized successively during the initialization; step2, the Gralloc module refreshes a UI portion of the first display screen and monitors control instructions from a UI man-machine interaction interface, double-screen display and video switch operations are performed if the control instructions are execution of double-screen display, and contents of the first display screen are transmitted to the second display screen to be displayed.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a dual-screen display method applied to an Android platform. Background technique [0002] The Android platform is specially developed for mobile smart display terminals, so the Android native platform (native Android platform) does not directly support the application environment with two display devices at the same time. Currently, the Android platform directly supports single-screen display, not directly Multiple display devices. With the popularization of the application of the Android system, more and more application environments urgently need to realize the dual-screen display function on the Android platform. [0003] To this end, an invention patent with application number 201310313896.4 discloses a dual-screen display method based on the Android system, which is applied to a display device based on the Android system, and the display device includes a first displa...
