2. What are Pixel Pitch, Pixel Density, LED QTY, and Pixel Configuration?
Pixel Pitch is the distance between neighboring pixels.
Pixel Density is the quantity of pixels per square meter.
LED QTY is the quantity of LED lamps per square.
Pixel Configuration is the description of the consistence of a pixel, for instance, we use 1 red lamp, 1 green lamp, and 1 blue lamp to compose a pixel, the pixel configuration is 1R1G1B.
3. What are LED Type, Module size and Module resolution?
LED Type is the description of LED lamp, for instance, the brand, the shape in physical, the size of the lamp, etc.
Module size is the measurement of a module.
Module resolution is the number of pixels per module.
4. What is Drive Method, driving IC and Power supply
Drive Method: always we use static, 1/4 scan, 1/8 scan, 1/16 scan, the latter one contributes to less brightness than the former. We always use the static outdoor, and use the different kinds of scan indoor.
Driving IC is the generic term for several kinds of IC, that are used to control the LED lamps, and as a bridge between the control system and lamps.
Power supply: a kind of device that used as a transfer from 220V AC into 5V DC. It always seems like a box in the cabinet.
