It refers to the SMT lamps packaged with LED chips of three different colors of RGB arranged vertically at a certain distance. This not only has all the advantages of 3-in-1 but also solves the various shortcomings of 3-in-1: complex process and difficult maintenance.

What is three in one?

It is to vertically juxtapose three independently packaged RGB SMT lamps at a certain distance. This not only has the advantages of 3-in-1, but also solves the shortcomings of 3-in-1.

What is a dual-color, pseudo-color, or full-color display?

Different displays can be formed by using light-emitting diodes of different colors. The dual primary color is composed of red, green, or yellow-green, the pseudo-color is composed of three different colors: red, yellow-green, and blue, and the full-color is composed of red. , pure green, pure blue three different colors.

What is luminous brightness?

The light intensity emitted by the LED display unit area is CD/square meter. Simply put, it is the light intensity emitted by a square meter display screen;

What is brightness level?

Manual or automatic adjustment of the entire screen brightness from the lowest to the highest brightness.

What is the gray scale?

Under the same brightness level, the number of technical processing levels between the darkest and the brightest display

What is the maximum brightness?

Under a certain ambient illumination, each primary color of the Mustang LED display is at its maximum brightness and maximum gray level;

What is moiré pattern?

When shooting a full-color LED display at work, some irregular water ripples will appear on the LED display screen. These water ripples are called "moiré" in physics.

What is PCB?

PCB is (abbreviation for printed circuit board) printed circuit board

What are unit board specifications?

Refers to the size of the unit board, usually expressed by the expression of the length of the unit board multiplied by its width, in millimeters. (48×244)

What is the resolution of the unit board?

Refers to how many pixels a unit board has usually expressed by the expression of the number of rows of pixels on the unit board multiplied by the number of columns. (Eg: 64×32)

What is BOM?

BOM is (abbreviation of bill of material) bill of materials

What is white balance and what is white balance adjustment?

What we call white balance refers to the balance of white, that is, the balance of the brightness ratio of the three RGB colors; the adjustment of the brightness ratio of the three RGB colors and the white coordinate is called white balance adjustment;

What is contrast?

The ratio of the LED display's highest possible brightness to the background brightness under specific ambient lighting conditions.

What is color temperature?

When the color emitted by a light source is the same as the color of light radiated by a black body at a certain temperature, the temperature of the black frame is known the color temperature of the light source.

What is chromatic aberration?

The LED display SMD screen uses a combination of red, green, and blue colors to produce various colors, but these three colors are made of different materials, the viewing angles are changed, and the spectral supply of different LEDs changes.

These differences that can be observed are called for color differences. When the LED is observed at a certain angle, its color changes. The human eye is better at judging the color of a real picture (such as a movie picture) than observing a computer-generated picture.
