dotpitch
The dot pitch is the distance between two print or image dots of the same color from a screen, printer, image sensor or scanner. The dot pitch, also known as the phosphor pitch, is called the stripe pitch when the phosphors are arranged in stripes. The smaller the dot pitch, the higher the image resolution and the brilliance of the image.
The dot pitch is specified in millimeters and stands for the diagonal distance between two color dots of the same color on the display. Typical values for the dot pitch are between 0.15 mm and 0.30 mm. For cathode ray tubes, the dot pitch is the distance between two holes in the shadow mask. This is about 0.2 to 0.3 mm and varies somewhat with tube design. For strip mask tubes, the strip pitch is between 0.2 and 0.3 mm.
Unlike displaying and reproducing devices, the dot pitch of image sensors is called pixel pitch. The values for the pixel pitch depend on the size of the image sensors, their resolution, sensitivity and dynamics and are slightly above 1 µm and range up to 10 µm.
