What's Essential Terms of LED display
LED brightness
The brightness of the light-emitting diode generally luminous intensity (the Luminous of Intensity) said that the unit is candela the cd; 1000ucd (micro candela) = 1 mcd (mm Kanla), 1000mcd = 1cd. Indoor use single LED's light intensity is generally 500ucd-50 mcd, outdoor single

The intensity of the LED should normally be 100 mcd to 1000 mcd, even more than 1000 mcd.
LED pixel modules
LED arranged in a matrix or strokes, pre-cast into a standard size module. Indoor display 8 * 8 pixel module, 8 characters, 7-segment digital modules. 4 * 4,8 * 8,8 * 16 pixels and other outdoor display pixel module specifications. Outdoor display pixel module because each of its pixels

LED tubes for more than two, it is also known for the set of bundles module.
Pixels (Pixel) with pixel diameter
Each of the LED display can be individually controlled LED light units (points) is called a pixel (or pixel). Pixel diameter ∮ means each pixel diameter, in millimeters. For indoor display, usually a single LED, the shape is round. Indoor display pixel

The diameter of the common school of ∮ 3.0, ∮ 3.75 ∮ 5.0, ∮ 8.0, etc., which ∮ 3.75 and ∮ 5.0.
In the outdoor environment, to increase the brightness increase in the line of sight, a pixel containing more than two cluster the LED; cluster LED above the two is generally not circular, so the outdoor display pixel diameter for general use 2 two pixel average spacing : ∮ 10, ∮ 11.5, ∮ 16, ∮ 22, ∮25.
Spacing, pixel density, and information capacity
LED display center distance or spacing of two pixels (Dot Pitch); the number of pixels known as pixel density per unit area; show the number of content contained within the unit area called the information capacity. These three nature is to describe the same concept: the spacing between two or two pixels.

LED display center distance or spacing of two pixels (Dot Pitch); the number of pixels known as pixel density per unit area; show the number of content contained within the unit area called the information capacity. These three nature is to describe the same concept: the spacing between two or two pixels.
To reflect the distance of pixel density, spacing and pixel density is a physical property of the display; information capacity is the number of units of the pixel density of the information carrying capacity. Spacing is smaller, the higher pixel density, the more information capacity, perfect for watching the closer the distance. Spacing the greater the
The lower pixel density, the less information capacity, suitable for viewing distance is farther.
Resolution
LED display pixel row and column number is called the resolution of the LED display. The resolution of the total pixels of the display, which determines the information capacity of a display.
LED display (LED Panel)
LED pixel modules arranged in accordance with the actual needs of the size of assembly matrix, together with the special display drive circuit DC power supply, software, frameworks, and outdoor decoration, etc., constitutes an LED display.
Grayscale
Grayscale refers to the degree of pixel light-emitting brightness changes one base color gray-scale is generally 8-12. For example, if each base color gray 256, dual color color screen, the display color 256 × 256 64K color, also known as the screen 256-color display.
Dual color
Today most of the color LED display is a dual color, color screen, each pixel has two LED die: a red die, a green die. The pixels in the red tube core bright red, green tube core bright pixels for the green, red, green and two core lit the pixels

In yellow. In which red, green, called the primary colors.
Full-color
The red and green dual color plus blue primary colors, three primary colors to form a full-color. Constitute the full-color blue and pure green tube core technology is now mature, so the market is basically in full color.
