The dot matrix display is a simple Chinese character display, which is cheap, easy to control, long service life and so on, can be widely used in various public occasions, such as station, Wharf, Bank, school, train, bus display. Now the streets are everywhere, so the study of dot matrix display is particularly important.

The dot matrix display with light-emitting diode as the element, it uses the high brightness led grain to carry on the array combination, then through the epoxy resin and the plastic mold encapsulation. With high brightness, low power consumption, less pin, angle, long life, moisture resistance, heat and cold, LED Dot Matrix Display corrosion resistance and so on.

Lattice display has monochrome and two colors, can show red, yellow, green, orange and so on. LED lattice has 4×4, 4×8, 5×7, $number, 8×8, 16×16, 24×24, 40×40 and so on, according to the number of the figure is divided into equal, double primary colors, three primary colors, etc., LED Dot Matrix Display according to the different colors displayed by the color of the text, images and other content of the color is also different, single color lattice can only display fixed , green, yellow and other monochrome, dual primary colors and three primary color dot matrix display content by the different color light-emitting diode light combination of the way to determine if the red and green are bright can display yellow, if the Pulse mode control diode light time, you can achieve 256 or more advanced grayscale display, LED Dot Matrix Display you can realize true color display.

Lattice display of internal circuit structure and external specifications, other models of lattice structure and pin can be tested, led lattice display single block, can be used in lieu of digital display of digital tubes, but also display a variety of Chinese and Western text and symbols. LED Dot Matrix Display such as 5 x 7 dot array display for Latin alphabet. The $number dot matrix display is used to display Chinese and Western text, and 8 x 8 dots are used to display the text and also to display graphics. A large-screen display can be formed by combining multiple lattice displays, LED Dot Matrix Display but this kind of utility device is often driven by microcomputer or MCU control.

The internal structure of the lattice display screen, the device should use dynamic scanning drive mode, because the LED tube core is mostly high-brightness, so a row or a column of the single led driving current can choose a narrow pulse, but the average current should be limited to 20mA. LED Dot Matrix Display Most of the lattice display of the monomer led pressure drop about 2V. But the large bright spot ∮10 the lattice display monomer LED’s positive pressure drop approximately is 6V.
