Resolution is an important parameter index of liquid crystal display, and often represents an important index of the display effect of liquid crystal display. Do you really know the LCD screen? Do you know that you can learn other information about the LCD screen from the resolution? Today I will take the 7-inch LCD screen as an example to share with you many years of industry experience.
The resolution of an 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 display image effect is relatively speaking.
Different sizes for different resolutions, the editor here gives examples of several common sub-resolutions and sizes. Common resolutions for 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 display include: 800*480, 800*1280, 1024*600, 1200*1920, 1280*768, 1920*1080, etc.
1. Judging the horizontal and vertical screen from the resolution of the LCD screen
How to judge the horizontal and vertical screens from the resolution is actually very simple. For example, 720*1280, the number 720 in the front is higher than the number 1280 in the back. In this case, it is a vertical screen, and 1280*720 is that the back number is smaller than the front number. It is the 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 more colorful the display, the common 7-inch LCD screen has a resolution of 720*1280, 1024*600, etc.
three. Judging 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=1.666..…;16:9=1.77777..... can be directly applied, that is, the result of dividing by the discrimination rate is the ratio of the 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 horizontal or vertical, and the aspect ratio of the screen.
