1, led brightness: the brightness of the light-emitting diode is generally used luminous intensity (Luminous Intensity) said, the unit is candela cd; 1000ucd (micro Candela) = 1 mcd (m Candela), 1000mcd = 1 cd. The light intensity of a single LED for indoor use is generally 500 ucd-50 mcd, while the light intensity for a single LED used outdoors is generally 100 mcd-1000 mcd, or even more than 1000 mcd.
2, led pixel module: led arrayed into a matrix or pen, pre-made standard size module. Indoor display commonly used 8 * 8 pixel module, 8 word 7 segment digital module. Outdoor display pixel modules have 4*4, 8*8, 8*16 pixels and other specifications. Pixel modules used in outdoor displays, because each pixel consists of more than two led tubes, it is also called a manifold beam module.
3. Pixel and Pixel Diameter: Each LED light unit (point) in the LED display that can be controlled individually is called a pixel (or pixel). The pixel diameter ∮ refers to the diameter of each pixel in millimeters. For indoor displays, generally one is a single led with a circular shape. Indoor display pixel diameter school common ∮3.0, ∮3.75, ∮5.0, ∮8.0, etc., of which ∮3.75 and ∮5.0 most.
4. Dot pitch, pixel density, and information capacity: The center pitch or dot pitch of two or two pixels of a led display; the number of pixels in a unit area is called the pixel density; the unit area contains the display. The amount of content is called information capacity. The essence of these three is to describe the same concept: the dot pitch reflects the pixel density from the distance between two pixels, and the dot pitch and pixel density are the physical attributes of the display screen; the information capacity is the information carrying capacity of the pixel density. The unit of quantity.
Six points to help you quickly become a leader in color screens
