You mentioned a 3.4-inch LCD panel with a resolution of 540*960 pixels and an aspect ratio of 16:9. This screen also supports full viewing angle or IPS (In-Plane Switching) display technology, and provides QSPI, RGB and MIPI interface options.
Resolution and aspect ratio
First, the resolution of 540*960 means that the display has 540 pixels in the width direction and 960 pixels in the height direction. This conforms to the aspect ratio of 16:9, which is a standard ratio widely used in TVs, computer monitors and mobile devices. It is based on ergonomic research and aims to match the best viewing experience of human vision.
Display technology
IPS technology is a type of liquid crystal display technology, which is characterized by electrodes located on the same plane instead of the traditional up and down arrangement, which can provide a wider viewing angle and better color performance. This means that users can get consistent color and contrast from any viewing angle, which is particularly important for applications that require high-quality images.
Interface type
Regarding the interface, this panel supports three different interface types:
QSPI: Quad Serial Peripheral Interface is a high-speed serial interface suitable for occasions where the amount of data transmitted is not particularly large, such as some simple graphical interfaces or low-resolution displays.
RGB: The parallel RGB interface is usually used to connect TFT-LCD panels. It can quickly transmit color information and is suitable for scenes with high refresh rate requirements. Depending on the configuration, the RGB interface can support resolutions up to 1920*1080
MIPI: Mobile Industry Processor Interface is an interface standard designed specifically for mobile devices. It can support higher data transmission rates and greater bandwidth requirements. It is very suitable for displays with high-definition or even ultra-high-definition resolutions.
