LED display classification:
LED display classification:Divided by brightness: indoor and outdoor (waterproof all outdoor, non waterproof half outdoor)By color: single color (single red, single green), two color (red green), full color (red green blue)Points by point size: indoor screen (points by point size) Φ 3mm、 Φ 3.75mm、 Φ 5mm, outdoor screen (divided by point spacing): pH2.5, PH3, pH4, ph6, ph7.62, PH10, pH12, ph14, PH16, PH20, pH2, such as outdoor p7.62 is equivalent to indoor Φ 5.

LED display detailed classification

screenThus, various displays can be combined according to the user's needs, such as indoor monochrome display Φ 3.75, half outdoor full color P10 displayOn the parameters of the display screen, there are also scanning modes, such as 1 / 4 scan, 1 / 8 scan, 1 / 16 scan, and interface modes: indoor 08 interface, outdoor 12 interface, and Working Voltage 5V. Of course, these have nothing to do with the type selectionControl card classification:According to synchronization and asynchronism:Asynchronous control: sending mode includes serial port, U disk, network port, WiFi, GPRS, mobile app (WiFi)Synchronous control: it needs to be controlled by the host computer.
the control modes include network port and graphics card (VGA, DVI and HDMI)By color: single color control, full color controlIn order to save costs, control card manufacturers usually divide the number of points of control card tape into different models according to the needs of users. For example, if some screens are large, the number of points of control card tape is large, and the selected card is large, the price of control card is high, while the number of points of small screen tape is small, so it is not economical to use large card to control, Therefore, the control card manufacturers have made low-cost small cards for these users.
1. According to the usage, there are three kinds of cards: outdoor, semi outdoor and indoor.
22. According to the type, there are dip and SMD3. According to pixels, there are P4, P5, P6, p7.62, P10, p16, P20, P25·······4. According to the color, there are single primary color.
double primary color and full primary color.
color5. According to the driving mode, it can be divided into static and dynamic.
dynamic can be divided into 1 / 2 scan, 1 / 4 scan, 1 / 8 scan and 1 / 16 scan.
the static display effect is the best and a little more expensive.
the static display effect is the best6. Classified by pixel, there are real pixels and virtual pixels.
the virtual pixel screen is basically no longer used now.
the virtual pixel screen is not used nowIf you want to order, you need to look at the materials used to make the display screen, such as chips.
this is very important.
