What is the midpoint distance of the liquid crystal Monitor

The point distance refers to the distance between the adjacent two pixel units on the screen, that is, the distance between two red (or green, blue) pixel units. From the principle, the general picture tube of the screen has a net cover, there are many fine holes, so called "shadow mask-type picture tube." The rays emitted by the electron gun pass through the holes, illuminate to the specified position and excite the fluorescent powder, and then show a point. Many different color points are arranged together to form a colorful picture.

Monitor Point distance

The point distance, sometimes also called "point spacing", "point pitch", I am afraid is the most frequently used vocabulary, then what is the point distance? If words too literally, the distance between two adjacent points is understood as a plausible answer. Dot distance of the English name is Dot pitch, and pitch intended as pitch, gear tooth section, meaning refers to the characteristics of the same two adjacent points between the distance, such as gear adjacent to the tip of the two teeth distance. So what do the dots in the picture tube stand for? In order to understand this concept, we first look at the color picture tube coloring principle.

We know that every color on the screen (called Pixel pixel) is a red, green, blue (referred to as R, G, B) of the three primary colors, through the shadow mask of the electron beam, according to the proportion of different intensity of light phosphor synthesis produces a variety of colors. For the sake of discussion, here we look at the shadow mask and the screen as a whole. For most picture tubes, the R, G, b fluorescent dots are arranged alternately by line following these principles.

1, the horizontal direction of the three primary colors repeat in a certain order;

2, the vertical direction of the same color point on a straight line;

3. Each specific fluorescence point is located in the middle of the adjacent two lines of other fluorescence points (the product zigzag arrangement).
