LED display Classification

At work
1, according to work points are two major categories: full-featured screen display and smart. Both international standards 8 × 8LED matrix modules assembled from (exactly the same screen surface, the basic display the same).
2, both the main difference is: Smart PC screen without connecting normally, the display has built-in CPU, can save multiple power-down screen can be run independently from the host computer. There is also some screen clock chip that can automatically display a calendar and clock. When the need to modify the display, through the RS232 interface to connect computer to modify. The full-featured screen must be connected to a computer to work.
Intelligent screen display is usually less, only the pop-up, pull-screen, roll-type, scroll type, and so are several display. The full-functional display screen is varied (if using professional software to create broadcast programs, the display has unlimited species).
Intelligent display simple: All you need to have special functional screen operation and maintenance (if you want to create animation programs, need specialized knowledge).

Color can be divided by color
Single-color display: Single color (red or green).
Dual-color display: red and green dual-color, 256 gray, you can display 65,536 colors.
Full color display: red, green, blue color, 256 gray level display can show full color more than sixteen million kinds of colors.

Divided by display
LED Digital Display: 7 segment display digital code, suitable for production of the clock screen, screen, and other interest rates, display digital electronic display.
LED dot matrix graphic display: display device is composed of many evenly composed of light emitting diode dot matrix display modules, suitable for broadcast text, image information.

Divided by using the occasion
Indoor displays: small light-emitting points, the general Φ3mm - Φ8mm, shows the general area of ​​a few to more than ten square meters.
Outdoor display: the general area of ​​tens of meters to several hundred square meters, high brightness, can work in the sun, with wind, rain, water resistant.

Light spot diameter divided by
Indoor screen: Φ3mm, Φ3.75mm, Φ5mm.
Room shielding: Φ10mm, Φ12mm, Φ16mm, Φ19mm, Φ21mm, Φ26mm.
Room shielding for the basic unit of light emitting tube, LED tube principle is a set of red, green, and blue light-emitting diode sealed in a plastic tube joint light enhanced brightness.
