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.
