With the rapid development of the LED display technology, LED electronic display and LED full color display, etc. LED display products is showing a diversified development, today's LED display is widely used in all walks of life, but for novice, many are jargon LED display do not understand, then what LED display common jargon, what does?

1, LED brightness: brightness light-emitting diodes for general use luminous intensity (Luminous Intensity) said that the unit is candela cd; 1000ucd (micro candela) = 1 mcd (milli candela), 1000mcd = 1 cd. Indoor single LED light intensity is generally 500ucd-50 mcd, and outdoor single LED light intensity should generally be 100 mcd-1000 mcd, even more than 1000 mcd.

2, LED pixel modules: LED arranged in a matrix or strokes, pre-cast into a standard-sized module. Indoor display commonly used are 8 * 8 pixel module, 8 characters 7-segment digital modules. Outdoor display pixel module has 4 * 4,8 * 8,8 * 16 pixels and other specifications. Outdoor display with pixel module because each pixel is composed of two or more of its LED tubes composition, it is also known as a set of modules which bundle.

3, the pixel (Pixel) with pixel diameter: LED display LED light emitting unit each can be individually controlled (point) is called a pixel (or pixels). ∮ pixel diameter refers to the diameter of each pixel in mm.

4. Resolution: LED display pixel row number is called LED display resolution. Resolution is the amount of pixels of the display, which determines the information capacity of a display screen.

5, gray: gray is the degree of light-emitting pixel shading, and one primary color gradation are generally 8-12. For example, if each color gradation is 256, for a two-color color screen, the display color 256 × 256 = 64K color, also known as the 256-color display screen.

6, dual-color: now most color LED display is a two-color color screen, that is, each pixel has two LED die: a red light die, a die for the green light. When the red light of the dice red pixel, the pixel is a green light when the green light die, die when the red and green lights at the same time the pixel is yellow. Wherein the red, green, called color.

7, full-color: red, green dual color plus blue primary colors, the three primary colors to form a full color. Since the blue tube and pure green die technology forms full color is now mature, so the market is basically in full color.
