About the resolution of LCD

  1. Resolution

Resolution is a very important performance indicator. It refers to the number of points that can be displayed horizontally and vertically on the screen (lines and planes on the screen are composed of points). The higher the resolution, the more information can be included in the same screen. 480×800 resolution and 320×240 resolution are perfect display. Because there is little difference between the two, but the maximum resolution is not necessarily the most appropriate resolution. If 480×8000 LCD is used in 320×240 LCD, the display content will be smaller.

 

  1. Visual area of LCD

It refers to the part of the display area that can be used to display the image in practical application. The full size is actually the size of its frame and PCB board, and the part that can be used to display images does not reach this size at all, because the frame takes up some space. Generally speaking, the area of 4-inch 480×800 LCD is 51.84×86.4mm, and that of 3.5-inch 320×240 LCD is 70.08×52.56mm. But for LCD, the size of area is basically the size of the visible area, and the space occupied by the frame is relatively small. The 4-inch 480×800 LCD has a display area of 51.84 * 86.4mm.So choose LCD screen, choose suitable for your own equipment.

 

  1. Reaction speed

The unit of time used to measure reaction speed is millisecond (ms), which is the time required for a pixel to go from light to dark and from dark to light. The smaller the number, the better. The smaller the number, the faster the reaction. At present, the reaction speed of mainstream LCD is more than 1-2ms, which has little to do with general industrial applications.

 

  1. Color

When it comes to colors, there are generally three kinds of colors: white blue background / black white background / black yellow background. Customers can choose LCD screen with different display colors according to different devices.
