Introduction of LCD resolution

LCD resolution, also known as resolution, represents the accuracy of the screen image and refers to how many pixels the display can display. Since points, lines and surfaces on the screen are composed of pixels, the more pixels the display can display, the finer the image, and more information can be displayed in the same screen area, so resolution is a very important performance indicator one. You can think of the entire image as a large chessboard, with resolution represented by the number of intersections between longitude and latitude lines. In the case of a certain resolution, the smaller the display screen, the clearer the image, on the contrary, when the display screen size is fixed, the higher the display resolution, the clearer the image.

For example, an LCD screen resolution of 1600×1200 means that there are 1600 pixels in the horizontal direction and 1200 pixels in the vertical direction, and a total of 1920000 pixels can be displayed. Since each pixel is composed of R, G, and B pixel units (or sub-pixels), and each pixel is displayed in red, green, and blue, there are about 5.76 million RGB pixel units (1600×3×1200≤5760000). In the case of the same screen size, the higher the resolution of the LCD screen, the better the display effect.
