If you have determined that you need to choose a navigator with a large screen, then the resolution of this product also needs to be included in your purchasing conditions. Many car owners have asked: how many pixels and how many screens are more suitable? Does the higher the pixel mean that the screen will not reflect light? If the screen size is different, can the navigation software of the same resolution work? Below, let us answer them one by one.

　　1. How many pixels are suitable for a large screen?

　　Generally speaking, we can infer the resolution of the product based on the screen size. At present, the resolutions of PND are mainly 320*240; 480*272; 480*234. Generally speaking, the 3.5-inch GPS resolution is 320*240, the general 4.0/4.2/4.3/4.7/4.8/5.0-inch GPS resolution is 480*272, and the high-definition one is 800*480 (4.7/4.8/5.0 The resolution of the 7.0-inch navigator is 480*234, the high-definition one is 800*480 (mainstream), and the higher one is 1440*234 (almost rarely).

　　2. The higher the pixel, the less reflective the screen will be?

　　Screen reflection is mainly related to the material used for the screen. At present, most of the screens used in GPS navigators are TFT screens (that is, thin-film transistor-type liquid crystal display screens). Although it improves the phenomenon that STN will flicker (water ripples) and blur, and improves the ability to play dynamic pictures, it is relatively expensive. Electricity, and this kind of screen will still be less clear in the sun, if the back of the screen adopts a high-brightness light tube, it may be possible to avoid the visual blind spot caused by sunlight reflection to the screen to the greatest extent, but the cost of doing so is relatively high. Therefore, whether the screen is reflective or not depends on the screen material. It should be reminded that the owner needs to accurately calibrate the screen when using it for the first time, and then the screen can be guaranteed to be clear.

　　4. Can the navigation software with the same resolution be universal for different screen sizes?

　　The navigation map of the device mainly depends on the resolution rather than the screen size. Even if the screen size of the navigator is different, the navigation software can still be used for the same resolution. In addition, when downloading free maps online, the main program and the skin must correspond to the screen size and resolution of the navigator.

　　Summary: It is necessary to choose a high-resolution GPS navigator. It is recommended to buy a product with a resolution of 800*480. It should be reminded here that the upgrade of the navigation map mainly depends on the resolution, even if the screen size is different, Navigation software with the same resolution can still be used in common.
