First component: LED unit board
The first component: LED unit board
it is one of the core components of LED display, The unit board is composed of LED module.
driver chip and PCB.

What are the components of LED electronic display screen?

LED module.
in fact, it is composed of many LED light-emitting points encapsulated with resin or plastic lattice.

the second component: wiring, which can be divided into data line.
transmission line and power line.
data line is used to connect control card and LED unit The transmission line is used to connect the control card and the computer.
the power line is used to connect the power supply, the control card and the LED unit board.
the diameter of the copper core of the power line connecting the unit board is not less than 1 mm.

the third component: the power supply
generally uses the switching power supply.
220 V input, 5V DC output.
it should be pointed out.
because LED display screen belongs to precision electronic equipment, switching power supply should be used instead of transformer.

the fourth component: control card
Zhanshi recommends low-cost strip screen control card.
it can control 1 / 16 scan 256 x 16 point dual color screen, The most cost-effective LED display can be assembled.
the control card is an asynchronous card.
in other words, the card can save information without connecting to a PC.
LED display: LED is the abbreviation of light emitting diodeIt is a display mode by controlling the semiconductor light-emitting diodes.
its general appearance is composed of many usually red light-emitting diodes, and the characters are displayed by the light on and off.
it is used to display text, graphics, images, animation, market, video, etc Video signal and other information display screen.
the characteristics and a little bit of new Asian victory.
you need to consult and investigate new Asian victory to know this! But if you need technical support for LED display, please contact me,
