Point distance

The meaning of the pixel pitch of the LCD display is similar to the dot pitch of the CRT. The dot pitch generally refers to the distance between two pixels adjacent to the display screen. The picture we see is formed by many points, and the fineness of picture quality is determined by the dot pitch. The dot pitch is calculated by dividing the panel size by the resolution, but the dot pitch of the LCD The importance of product performance is far less important than the latter.

The pitch of the CRT will vary depending on the design of the shadow mask or grating, the type of video card, and the vertical or horizontal scanning frequency, while the number of pixels on the LCD display is fixed, so the size and resolution are the same. In most cases, the pixel pitch of most liquid crystal displays is basically the same. A 15-inch LCD display with a resolution of 1024 x 768 has a pixel pitch of 0.297 mm (also some products are labeled as 0.30 mm), and the 17-inch LCD is basically 0.264 mm. Therefore, the price of the same size LCD is generally not related to the dot pitch.
