Dual-screen display technology is widely used in smart self-service terminals. This technology allows two LCD screens to be driven simultaneously on the same hardware platform, with different content displayed on each screen.
Implementing dual-screen display functionality helps users reduce hardware costs; it also significantly enhances interactivity in consumer scenarios; additionally, it simplifies installation and saves space. The most cost-effective dual-screen display motherboard solutions currently are the RK3288 and RK3399. The following questions are the most common when setting up dual-screen displays:
1
How to achieve dual-screen display? Is there source code available?
The RK3288 and RK3399 series Android motherboards from Smartview support dual-screen display. The standard firmware for these motherboards defaults to support dual-screen mirroring. To use dual-screen display, users need to configure the screen parameters and install the dual-screen display testing DEMO after configuration. Specific materials and operation tutorials can be obtained from the Smartview official website (http://www.smdt.com.cn) under 【Service and Support】–【Document Center】:

Can one screen be horizontal and the other vertical, displaying separately?
The custom firmware for RK3288 and RK3399 supports individual rotation of the main and secondary screens, but does not support running two APKs simultaneously.
