Led display

LED stands 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.

Pixel pitch describes the density of the pixels (LED clusters) on an LED display and correlates with resolution. Sometimes referred to as pitch or dot pitch, the pixel pitch is the distance in millimeters from the center of a pixel to the center of the adjacent pixel. Since pixel pitch indicates the amount of space between two pixels, a smaller pixel pitch means there is less empty space between pixels. This equates to higher pixel density and improved screen resolution.

Pixel Density is the number of pixels per square meter.

LED QTY is the quantity of LED lamps per square.

Pixel Configuration is the description of the consistency 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.

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.

Drive Method:  We always 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, which 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.

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.

SMD LED is an abbreviation for (Surface-Mount-Device, Light-Emitting-Diode) it’s a type of LED characterized by having a 3 in 1 encapsulation, meaning that it integrates all 3 colors (Red, Green, Blue LED chip) into a single system.

The assembly on the circuit board is done by a polarization process on the front of the LED module. It is important that this process is carried out with high-quality equipment in order to avoid future problems such as loose or non-functioning LEDs.

The brightness level for LED is important to consider if the LED display can be visible clearly under different environments. Such as it can be viewed and used under sunshine, outdoor, etc.

Basic guidance for brightness level for different application

Indoor  Brightness:  800 – 1,500 nits

Outdoor Brightness : 2,000 – 3,000 nits

Outdoor Brightness Under direct sunlight: 4500-6000 nits

Outdoor brightness in desert climate under direct sunlight: 7000 -1200 nits
