Abstract

The invention discloses a double-screen display method and a double-screen display device. The double-screen display method comprises the steps of detecting whether terminals support double-screen display or not, wherein double screens comprise a main display screen and a subsidiary display screen; if so, generating HDMI (High-Definition Multimedia Interface) equipment adding events; according to the HDMI equipment adding events, taking the subsidiary display screen as HDMI equipment for initialization; after initializing the subsidiary display screen, conducting double-screen display. By the method and the device, a problem that the double-screen display method has huge development work and relatively weak compatibility in a prior art is solved, and the subsidiary display screen can be simulated into the HDMI equipment and displayed by an original HDMI display mechanism in an operating system, and thus the display mechanism of the subsidiary display screen is not again developed and has no compatibility.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular to a dual-screen display method and device. Background technique [0002] Dual-screen display refers to the technology of simultaneous display on electronic devices through the main display screen and the secondary display screen. The native display mechanism of the Android operating system usually only supports the display of one display screen, that is, the display of the main display screen. [0003] The method for realizing dual-screen display in the prior art includes: in the Android operating system, using a native display mechanism to realize the display of the main display; show. The secondary screen display mechanism includes a whole set of device-related interfaces from the bottom driver to the application layer. [0004] In the process of implementing the embodiments of the present invention, it is found that the prior art has at least the ...
