“PH” is the abbreviation of Pixel Pitch, It means the distance from the center of one pixel to its neighboring pixel center. It usually be measured in MM, For Example, “P6 Outdoor LED Screen” means its pixel pitch is 6mm.
- They are used in different environments Indoor/Outdoor.
- Indoor LED Display is not waterproof Usually IP30/IP31, while Outdoor LED Screen at least IP54 UP.
- Indoor LED Display brightness is from 100nit to 2,000nit, while the outdoor LED Screen at least up to 3000Nit.
- Indoor LED Lamp Usually uses SMD1010, SMD1515, SMD2121 or SMD3528, While Outdoor LED Screen Use DIP346, SMD3535, SMD2727, SMD1921, indoor LED Lamp is not waterproof, very scare of Moisture, but Outdoor LED Lamp is waterproof, anti-UV, and have good heat deception.

LED Display Color depth is the main parameter of a LED Screen, it indicates the color that the LED Screen can show, for example, 13bit color depth means each of R, G, B can have 13bit (2^13) brightness, and the whole screen can have 2^13* 2^13 2^13=549,755,813,888 colors. The more big Color depth that the display will have fine and smooth display performance.
Pixel pitch is the distance between the center points of two adjacent pixels on LED Display. The unit is usually in millimeters (mm). Usually, the pixels are equally spaced in the horizontal and vertical directions, and there are also excerpt, such as: Transparent LED Display Screen. For example, P5 means that its pixel pitch is 5mm.
COB(Chip-On-Board) and SMD(Surface-Mount-Devise) are the same kind of LED packaging method. However, the difference is that SMD is called surface mount packaging technology, which means that the wicks are soldered one by one on the PCB to make the cell board; and COB integrates the light emitting chip. In the PCB board, it is not soldered to the PCB board one by one like SMD.
The COB display is a COB display composed of a display module made of COB technology.

There are 2 main type of Control method,
Synchronous Control system: the LED Display is synchronous with the control pc monitor.
Asynchronous Control system: the LED Display read from the asynch control card memory card, no need a control pc.
We Usually Accept T/T payment way for big LED Display Screen purchase payment, the rate is 30% deposit and 70% balance before shipping. For some LED Display componants can also paid by Paypal, Westunion.
