　　The quality of the screen is one of the important factors in selection, and it mainly depends on indicators such as screen resolution, color reproduction, viewing angle, and response time. Generally speaking, the higher the resolution, the better the color reproduction, the wider the viewing angle, the shorter the response time, and the higher the quality of the screen.

Sizes that are too large or too small will cause inconvenience in daily use. Therefore, it is more important to choose the appropriate size according to the usage scenario.

　　4. Screen interface type

　　The interface types of the screen include SPI, RGB, MIPI and LVDS. The SPI interface is the most common one and is suitable for microcontroller products. The RGB interface is commonly used in industrial fields, and the MIPI interface is commonly used in high-end applications. The LVDS interface is suitable for high-resolution, high-speed display screens. Therefore, when selecting a screen, you need to select an appropriate interface based on the actual application scenario.

　　5. Protective performance

　　During use, the 4 inch LCD screen needs to have good protective properties, such as earthquake resistance, waterproofing, and dustproofing. These are all things to consider when choosing a screen.

　　To sum up, choosing a suitable 4 inch LCD screen needs to be based on the quality, size, interface type and protective performance of the screen.
