The grid pitch refers to the distance between the parallel gratings of the cathode grid picture tube (in mm). The advantage of using a cathode grid picture tube is that its grid pitch will not deform after long-term use, and the customized display will not experience a decrease in image quality after years of use.
Dot pitch (or stripe pitch) is a very important hardware indicator for customized display screens. It refers to the distance between a light point of a certain color and an adjacent light point of the same color. This distance cannot be changed by software. This is different from resolution. At the same resolution, the smaller the dot pitch, the clearer and more delicate the displayed image, and the higher the resolution and image quality.
