You are describing a 2.83-inch rectangular LCD module with a resolution of 400x800 pixels and a 2:1 aspect ratio. This screen also supports QSPI (Quad SPI), RGB, and MIPI interface standards, allowing it to be compatible with a variety of processors or controllers.
The use of full-view/IPS technology means that the display provides wide viewing angles and better color reproduction, maintaining image quality even when viewed from the side. This type of screen is ideal for applications that require high visibility and accurate color display, such as portable devices, smart home products, industrial control panels, etc.
Due to its unique 2:1 aspect ratio, a screen of this size and resolution may be particularly suitable for interface designs that require more space in the vertical direction, such as e-book readers, small POS terminals, or any application that wants to provide a longer content display area within a limited physical space.
If you have specific application questions about this LCD module, or need further technical information such as brightness, contrast, operating temperature range, touch function (if any), etc., please feel free to let me know.
