Dot pitch
Dot pitch
Dot pitch is a measure of the distance between pixels. The smaller the dot pitch, the better the picture.
.
There is no proportional or inversely proportional relationship between dot pitch and refresh rate. The higher the dot pitch, the tighter packed pixels are, meaning more rows and more columns in the same space. Typically higher video resolutions can be achieved. The higher the refresh rate, the faster all rows are rescanned. Measured in Hertz, or the number of complete scans per second.
It is called dot pitch the measurement from the center of one hole to the center of the hole next to it.

The primary difference between the two lies in the rear display. The TL225, which will sell for $350, offers a 3.5-inch touch-screen display with a very high 1,1152K dot resolution and haptic feedback when touched. The TL220, priced at $299.99, also offers a touch-screen with haptic feedback, but at a smaller 3-inch size and more standard 230,000 dot resolution.
The dot pitch for a display unit is the distance between individual dots - which may be circular or in the form of an elongated circle (like a running track). Most display units, nowadays, are based on dots of three colours: red, green and blue. A pixel is unit formed by each set of three colours, and a pixel pitch is a measure based on the size of the pixel and the distance between dots of the same colour in adjacent pixels.
