What is LED?
LED is sanded for Light Emitting Diode, a kind of semiconductor which is used to give and receive the electronic signal into infrared rays or light, using the characteristics of compound semiconductor. This is used for household appliances, remote controller, electric bulletin board, various kinds of automation appliances.

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 meter.
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.

5. What is viewing angle?
Viewing angle is the maximum angle at which a display can be viewed with acceptable visual performance. It includes horizontal viewing angle and vertical viewing angle.

6. What are refresh rate and frame rate?
Refresh rate is the number of times a display’s image is repainted or refreshed per second. As it denotes a frequency of a process, the refresh rate is expressed in hertz. That is, a refresh rate of 75 Hz means the image is refreshed 75 times in one second.
Frame rate, or frame frequency, is the frequency (rate) at which an imaging device produces unique consecutive images called frames. The term applies equally well to computer graphics, video cameras, film cameras, and motion capture systems. Frame rate is most often expressed in frames per second (FPS), and is also expressed in progressive scan monitors as hertz (Hz).

7. What is grey level?
Grey level: A calibrated sequence of grey tones, ranging from black to white. In remote sensing, electromagnetic radiation falling on a photosensitive receiver generates an electrical current proportional to the intensity of the radiation. The receiver is usually tuned to specific wavelength bands and the signal from each receiver is amplified and its intensity classified into different levels, usually 0 (black) to 256. These are the digital numbers of each of the pixel units that together make up a remotely sensed frame.
