Resolution is an important parameter index of the liquid crystal display, which often represents an important indicator of the display effect of the liquid crystal display. Do you really understand LCD screens? Did you know you can learn something else about an LCD screen from resolution? Today, the editor takes a 7-inch LCD screen as an example to share with you many years of industry experience.
The resolution of the LCD screen refers to the number of pixels on the LCD screen, usually the number of pixels in the horizontal direction multiplied by the number of pixels in the vertical direction. In the case of the same LCD screen size, the higher the resolution, the clearer the displayed image is.
Different sizes and different resolutions, here are some examples of common resolutions and sizes. The common resolutions of 3.5-inch TFT displays include: 240*320, 320*480, 480*272, 480*854 and many more. 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 of 7.0-inch TFT displays include: 800*480, 800*1280, 1024*600, 1200*1920, 1280*768, 1920*1080 and so on.
1. Judging the horizontal and vertical screen from the resolution of the LCD screen
How to judge the horizontal and vertical screen from the resolution is actually very simple, such as 720*1280, the front number 720 is higher than the back number 1280, this case is a vertical screen, and 1280*720 In this case, the back number is smaller than the front number, then It's horizontal screen.
2. Judging the display effect from the resolution
Judging the display effect of the 7-inch LCD screen from the resolution, this is easy to understand, that is, the higher the resolution, the better the display effect, that is, the more pixels. The richer the colors displayed, the common 7-inch LCD screen resolutions are 720*1280, 1024*600, etc.
three. Determine the aspect ratio of the screen from the resolution
Anyone who knows the 7-inch LCD screen industry must have heard of the aspect ratio. For example, the aspect ratio of a 7-inch LCD screen with a resolution of 1024*600 is 16:9. How is this calculated? You can also search for the formula on the Internet. The editor summarizes it as 4:3=1.3333....; 16:10=1.6666...; 16:9=1.77777..... It can be directly applied, that is, divided by the discrimination rate The result is the ratio of 7-inch LCD screen, for example, 1280*800 is the ratio of 7-inch LCD screen? 1280/800=1.6, 16:10=1.6666... Then it is a 7-inch LCD screen with a 16:10 resolution of 1280*800.
After reading it, do you feel awkward? From the resolution of the 7-inch LCD screen, you can not only know the display effect of the 7-inch LCD screen, but also know whether it is a horizontal screen or a vertical screen, and know the aspect ratio of the screen.
