Dot-matrix displays are ubiquitous in our lives, such as companies, banks, buses, and outdoor billboards.

The dot matrix display is composed of tens of thousands of-hundreds of thousands of semiconductor light-emitting diode pixel points uniformly arranged. The dot matrix display uses different materials to produce different colors of LED pixel points. The dot matrix display is a way to control the display of semiconductor light-emitting diodes, the dot matrix display is used to display text, graphics, images, animation, quotes, video, LED Dot Matrix Display video signals and other information display screen.

Dot matrix display features are as follows:

Dot-matrix display can achieve ultra-high density: indoor up to 62.5 points/square meters (P4).

Dot matrix display Color good: the use of the light-emitting device itself micro-processing and light wave-particle duality, so that red particles, pure green particles, LED Dot Matrix Display blue light particles three kinds of particles will be fully mixed together.

Dot-matrix display antistatic Performance Advantage Super: The production environment has strict standards and product structure insulation design.

Lattice display reliability can be strong: relative to SMD and Ledlamp, LED Dot Matrix Display Leddot-matrix smoothness is very good, very aesthetic perception.

Dot-matrix display visual angle is large: 140 degrees (horizontal direction)

Dot-matrix display high permeability: The new generation of lattice technology by virtue of its own high purity of the performance of the chip, as well as nearly 100% optical transmittance of epoxy materials, reached a close to the perfect permeability rate.

Dot-matrix display brightness: relative to 0603 or 0805 of the form of discrete table stickers, led can have more luminous flux is reflected out, and our current

Lattice display utility model patent; 4×4 module form, can achieve 1/4 scan, further improve the brightness.

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, 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, LED Dot Matrix Display according to the number of the figure is divided into equal, double primary colors, three primary colors, etc., 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, you can realize true color display.

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

By the internal structure of the dot matrix display, it is advisable to use the dynamic scanning drive mode to work because the LED tube core is mostly high brightness type, so a row or a column of the single led driving current can choose narrow pulse, but its average current should be limited to 20mA, 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.

The display mode of each module in the dot matrix display has two kinds of static and dynamic display. The static display principle is simple, the control is convenient, but the hardware wiring is complex, LED Dot Matrix Display in the practical application, the dynamic display mode is used in the dynamic display, and the scanning mode is used, which is driven by the narrow pulse of the high peak, and the successive rows of the display screen are selected from top to bottom, and the pulse signal of the graph or text information is sent to each column. Repeat the loop over and over again to display a variety of graphics or text information.
