4 Video I/O Interfaces
N1video I/O interfaces comply withthe Mobile Industry Processor Interface (MIPI) standard to transmit
high-speed digital signals. This standard is widely supported by many device manufacturers. So it is easy
to get video devices that support this standard.
4.1 LCD Interfaces
LCD interfaces, the video output interfaces of the N1module, are developed based on the MIPI_DSI
standard. They support 4-lane high-speed differential data transmission, each of which can achieve a rate
of at most 1.5 Gbps. Configure different quantity of MIPI_DSI as required.
4.1.1 WVGA
The following sections describes the hardware configuration of WVGA display that Neoway
commissioned.
The resolutionof WVGA display is 800 x 480, which requires 2-lane MIPI_DSI. LCD design is generally
to connect FPC to the connector. Table 4-1lists the LCD pins.
