How to understand the resolution of LCD display screens?

Date:2024-06-12

        The resolution of an LCD screen refers to the number of pixels in the screen, usually multiplied by the number of pixels in the horizontal direction. For the same size of LCD screen, the higher the resolution, the clearer the displayed image.

       Different sizes have different resolutions. Here are a few common resolutions and sizes:

　　The common resolutions of 3.5-inch TFT displays include: 240 * 320, 320 * 480, 480 * 272, 480 * 854, and so on.

　    The common resolutions of 5.0-inch TFT displays include 720 * 1280, 768 * 1024, 768 * 1280, 800 * 480, 854 * 480, 1024 * 600, 1080 * 1080, and so on.

      The common resolutions for 7.0-inch TFT displays include: 800 * 480, 800 * 1280, 1024 * 600, 1200 * 1920, 1280 * 768, 1920 * 1080, and so on.

      1、Judging horizontal and vertical screens from the resolution of LCD screens

       How to determine the horizontal and vertical screen based on resolution is actually quite simple. For example, 720 * 1280, where the number 720 in front is greater than the number 1280 in the back, is considered a vertical screen. In contrast, 1280 * 720, where the number behind is smaller than the number in front, is considered a horizontal screen;

       2、 Judging Display Effects from Resolution

　   Judging the display effect of a 7-inch LCD screen from its resolution is easy to understand. The higher the resolution, the better the display effect, that is, the more pixels there are, the richer the displayed colors. Common 7-inch LCD screens have resolutions of 720 * 1280, 1024 * 600, etc;

        3、 Judging the aspect ratio of a screen from its resolution

　　Those who are familiar with the 7-inch LCD screen industry must have heard of aspect ratios. For example, a 7-inch LCD screen with a resolution of 1024 * 600 has an aspect ratio of 16:9 on the display screen. How is this calculated? You can also search for formulas online, and the editor summarizes them as 4:3=1.3333..., 16:10=1.6666..., 16:9=1.77777... which can be directly applied, that is, the ratio of a 7-inch LCD screen divided by discriminat.
