Display resolution

- Mar 15, 2020-

Resolution is one of the important parameters in both LCD and traditional CRT displays.

Traditional CRT displays support more flexible resolutions, while liquid crystals have fixed pixel spacing, so there are not as many display modes as CRTS.The best resolution, also known as the maximum resolution, is the resolution at which the LCD displays the best images.

When an LCD displays a low-resolution display mode, there are two ways to display.The first is centered display: for example, when SVGA 800×600 is displayed on the XGA 1024×768 screen, only 800×600 pixels in the center of the screen are rendered, while other pixels that are not rendered remain dark.At present, this method is seldom used.The other is called extended display: when a picture is displayed with a lower resolution than the best, each pixel is extended to the adjacent pixel by differential algorithm, so that the whole picture is filled.This also makes the picture lost the original clarity and true color.

Because the maximum resolution in the same size of the LCD is consistent, so the price of the same size of the LCD is generally not related to the resolution.

Never look at the brightness contrast when you buy an LCD and forget to look at its physical resolution.
