1. Introdution
This is a 15.6-inch IPS capacitive touch display with a resolution of 1920×1080 that supports full-function Type-C or HDMI signal input. It is compatible with single-board computers such as LattePanda Sigma, LattePanda 3 Delta, LattePanda Alpha, LattePanda Delta, Raspberry PI 4B and Jetson Nano, as well as various types of desktop computers, laptops, mini PCs, industrial computers and tablets.
The Full-function Type-C display interface is a multi-functional interface standard, through a Type-C data cable can achieve a variety of functions, including audio transmission, video transmission, charging and touch functions. In addition, the fully functional Type-C interface also supports reverse PD power to providing power for connected devices. This interface enables the integration of multiple functions through a single Type-C connection, thus simplifying the connection and providing a more convenient user experience, with flexibility and versatility.
Drawn from these merits, the display is adorned with a pair of identical all-encompassing Type-C interfaces, meticulously engineered to accommodate blind insertion, obviating the need for a deliberate demarcation between data conduit and power supply port. Simultaneously, the product retains the conventional and widely embraced HDMI display interface, thereby ensconcing compatibility with a broader spectrum of HDMI output devices.
In addition, with the 15.6-inch large screen display and ten-point touch function, the product is very suitable for human-computer interaction scenarios. Its 1920×1080 high-definition resolution, IPS full view, full fit process and surface anti-glare treatment and other high-quality parameters, make it more scene applicability.

6.3.1 Type-C Audio-Video Input
Example: LattePanda 3 Delta
The Type-C interface of Delta 3 supports audio-video, touch signal, and power signal input. Here, a versatile Type-C data cable is required to establish the connection between Delta 3 and the screen. The reverse power supply for Delta 3 is facilitated by the display driver board.
The connection is as depicted in the diagram.
Note: The two Type-C interfaces on the display driver board have identical functionalities, eliminating the need to distinguish between data and power ports, allowing for blind insertion.
6.3.2 HDMI Audio-Video Input
Example 1: Raspberry Pi 4B
Utilize the provided HDMI A to D conversion module for HDMI connectivity. Subsequently, employ a USB data cable to establish a connection from the Raspberry Pi's USB port to the USB-C CN2 interface on the display driver board, enabling touch functionality. Refer to the illustration below.
Note: The USB port output current of the Raspberry Pi is insufficient to power the screen's activation. Hence, a separate power supply is necessary for the display driver board.
Example 2: LattePanda 3 Delta
Utilize the provided HDMI A to A conversion module for HDMI connectivity. Subsequently, employ a USB data cable to establish a connection from the 3 Delta's USB port to the USB-C CN2 interface on the display driver board, enabling touch functionality. Refer to the illustration below.
Note: The USB port output current of Delta 3 is capable of powering the screen's activation, eliminating the need for a separate power supply for the display driver board.

FAQ
Q: Why is there no touch response when HDMI signal is input, and the screen displays correctly?
A: Firstly, ensure that the touch USB signal on the mainboard is properly connected to the Type-C CN2 interface on the display driver board. Please be aware that touch functionality can only be facilitated through the Type-C CN2 interface when operating in HDMI mode. Secondly, once the correct connection is verified, it is advised to inspect the continuity and quality of the connections on the touch control board to ascertain their proper contact.
