The whole image can be imagined as a big chessboard, and the resolution is expressed by the number of intersections of all warp and weft. When the display resolution is fixed, 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.
Image resolution is the number of pixels per inch, and its definition is closer to the definition of resolution itself.
Extended data:
Taking LCD as an example, the visible area of a 14-inch LCD is generally 300mm× 190mm, and the resolution is 1280×800. Then, it is calculated that the dot distance of this LCD is 300/ 1280=0.2344mm or/kloc. The smaller the point distance, the finer the image.
16:1022 (21.5) and 20(20. 1) inch widescreen liquid crystals have the best resolution of 1680× 1050.
The optimal resolution of 23-inch and 22-inch (2 1.5) widescreen LCD with the ratio of 16:9 is 1920× 1080.
The refresh frequency of LCD is 60Hz, which is the default setting of operating system. Do not change it (no matter how much the system defaults). LCD is not a CRT display, nor is it a cathode ray tube inside, nor does it produce images by bombarding the fluorescent powder on the CRT with an electron gun.
The LCD passively emits light by lighting the LCD panel in front of the lamp at the back, and there are only differences between bright and unlit, bright and dark. Therefore, LCD does not have the principle that the electron gun scans the screen line by line and interlaced, so there is no concept of refresh frequency. It is the same whether it is changed or not, and the refresh frequency has no effect on all liquid crystals.
