With regard to LED displays, there are a lot of technical terms. There are many pixels, dot spacings, scanning methods, etc., then the concept of these common LED display nouns is explained in detail. The following are the details provided by Lianchengfa Group: References.
(1) Pixel: It is the smallest imaging unit of LED display. Commonly known as "point" or "pixel".
(2) Pitch: It is the distance between two pixels in mm. The denser the dot pitch, the more pixels per unit area, the finer the displayed screen, and the more expensive the display screen. The concept of dot pitch is usually used for outdoor screens, P6, P7.62, P8, P10, P12, P16, P20, etc., and wrote an article “How to select LED display based on dot pitchâ€. And choose to do a detailed explanation.
(3) Scanning mode: The scanning mode determines the mode of connection between the modules. The scanning modes are 1/16, 1/8, 1/4, 1/2, and static. Because the LED display is refreshed line by line, the scanning method also determines the way the display is refreshed. For example, 1/16 is to refresh 1 line at a time, and 16 is a scanning cycle. It requires ABCD four signals to control; 1/8 is Each time a row is refreshed, 8 is a scan cycle, three signals are required for ABC control; the others are analogized in turn. If the same LED light is used, the brightness of 1/16 sweep is lower than 1/8 and the static (1/1) brightness is the highest. Indoor screens generally use 1/16 scanning, while outdoor and semi-outdoor applications generally use 1/16 or 1/8. For environments where screens are often exposed to intense sunlight, it is best to use a 1/4 scan.
(4) Display module: A minimum unit that is composed of a number of display pixels and is structurally independent and constitutes an LED display screen. The indoor screen uses an 8x8 display module, ie each display module has 64 pixels; the outdoor screen uses a single lamp bead, usually consisting of one to three pixels of the same or different color lamp beads.
(5) Display module: The independent unit that constitutes the LED display screen, which is determined by the circuit and mounting structure and has a display function. Simply put, for ease of assembly and display, the factory semi-finished product is usually provided in the form of a display module, and a plurality of display modules are added together to drive the display together. Indoor screen is commonly called "cell board"; outdoor screen is commonly called "module", and several modules are added together with chassis, fan, and power supply to form a "box", which is mostly used for large full-color screens. The indoor screen unit board usually has 64x32 (64 columns and 32 rows, consists of 32 modules), 64x16 (64 columns and 16 rows, consists of 16 modules), etc. The outdoor screen module usually has 64x32, 32x32, 32x16, 16x16, 16x8 Variety.
(6) LED display screen body: The unit board/module/box is spliced ​​together in a certain way, plus a control card/control system, power supply and frame, etc. to form an LED display screen.
(1) Pixel: It is the smallest imaging unit of LED display. Commonly known as "point" or "pixel".
