> **Table: Interfaces and capabilities**
>
> | **Interface** | **Capabilities** |
> | - | - |
> | DSI0 | Supports 1080 × 1920 at 60 fps 24 bpp with DLC0697 panel 4-lane MIPI DSI, RGB888, video mode |
> | Maximum concurrency | Single display (DSI0 only) |
>
> ## Display daughtercard (CTP, DSI D-PHY)
>
> The capacitive touch panel (CTP) display daughtercard connects the CQ2390 evaluation kit (EVK) to the external LCD panel. It routes DSI0 from the carrier board to the panel and provides the panel-bias supply and backlight drivers.
