LED the so-called static screen is with the scanning screen corresponding (dynamic screen). Static screen refers to the screen shows, all the lights lit at the same time. And scanning screen is the use of persistence of vision characteristic of human eyes, in a very short period of time will LED display all light respectively. LED display is driven by duty ratios, so the brightness of the display has a lot to do with the light of time cycle. Under the same brightness light-emitting tube, static screen is higher than scanning the brightness of the screen, so generally outdoor screen with static screen, indoor screen by scanning screen, driven to save cost.
Since said big driver, we dropped in to talk about static drive and dynamic drive.

Driver IC output feet to the practice of "point to point" between pixels is called static drive, the control of output from driver IC feet to the practice of "point to the column" between pixels of control is called scanning drive, he needs to control circuit, can see clearly from the driven plate: static drive line don't need to control circuit, high cost to teach, but shows the effect is good, good stability, brightness loss taught, etc.; Scan line drive it need control circuit, but the cost is low, the display effect is poor, brightness loss a big, etc. So do you have any characteristics of two kinds of driver?

The advantages/disadvantages of static driver
advantages
LED display components between attachment is very concise, only 5 to 6 wires can be all LED series, debugging maintenance is convenient.
Display brightness is good, the suitable driving element can drive 2 meters of the LED, is suitable for making large digital outdoor screen.
disadvantages
Each LED need 1-2 driver IC, need the display component PCB making.
Larger power consumption (scan driver is five times).
Cost a little higher (the average display drive part of the cost of RMB 0.4 1) higher than scanning drive.

The advantages/disadvantages of scan driver
advantages
Display driver circuit simple, 2 IC can drive eight 10 "the following leds, the cost is low.
Leds can be directly with the main control board of all sizes. Drive plate. Extension plate connection, even don't use PCB board.
Low power consumption. Using time-sharing scanning display mode, power consumption is only about 1/5 of the static display.
disadvantages
Attachment between LED to the driver board more root (8 + LED number). When digit is large, attachment and repair inconvenience.
In simple terms, the dynamic panel is more than one IC feet with two lamp, and a static screen with only 1 light. But now the brightness of the LED tube, outdoor has useful scanning screen oh!
