1. How to realize dual-screen display?
Lianzhitongda's RK3288 and RK3399 series Android motherboards can support dual-screen differential display. The standard production firmware of these motherboards supports dual-screen simultaneous display by default. If you need to set dual-screen differential display, the user needs to configure the screen parameters and complete the screen parameter configuration. Later, install the dual-screen differential display test DEMO.
2. Is it possible to have one screen in landscape orientation and the other in portrait orientation, so that they display differently?
RK3288 and RK3399 customized firmware can support independent rotation of the main and secondary screens, but does not support running 2 apks at the same time.
3. How to implement RK3288 series?
If it is dual-screen differential display of LVDS/HDMI/eDP, you can choose the RK3288 series, which supports any combination of two out of three to achieve dual-screen differential display.
4. How to implement RK3399 series?
If it is dual-screen differential display of LVDS/HDMI/MIPI, you can choose the RK3399 series, which supports any combination of two out of three to achieve dual-screen differential display.
The realization of the dual-screen differential display function, first of all, helps users reduce the cost of hardware equipment; secondly, it is of great significance for improving the interactivity of consumption scenarios; thirdly, installation and deployment are simpler and space-saving.
