The Accessories and Parameters That Make Up the Indoor LED Display

Ⅰ. What are the accessories that make up the indoor LED display?

A complete indoor LED display screen is assembled from a variety of accessories, which take over different parts of the display. Next, XMOZU will introduce the important accessories of the indoor LED display screen in detail.

1. Box

First of all, let's start with the appearance. The box is the body of the LED display. If there is no good organ in the box, there is no chance to show it.

Generally speaking, boxes have different sizes, each box is a component composed of multiple unit boards, and then the multiple boxes are assembled into a screen in turn.

2. Power

The power supply is like the blood in the indoor LED display screen of the banquet hall. Good blood can make the human body comfortable and smooth, but on the contrary, it can cause various human diseases.

For the LED display, the quality of the power supply also determines the quality of the product. Different types of screens have different power requirements for the power supply.

3. Module

All LED screens are composed of modules, which are assembled from various accessories such as bottom shells, kits, masks, etc., and finally form an LED display that we see every day.

4. Control system

Compared with the control system, I don’t need to say more about its importance. It is equivalent to the brain of our human body that controls our thoughts, and all the pictures we see are signals sent from here.

The control system also plays the same role in the LED mirror screen. Through a series of steps such as the receiving card, the adapter board, the indoor LED display screen, etc., a very beautiful picture will finally be displayed.

Ⅱ. Indoor LED display parameters

LED displays are now used in major shopping malls, hospitals, schools, etc. Since LED displays are based on LEDs, most of their optical, electrical characteristics and limit parameters are the same as those of light-emitting diodes. However, since the led display contains multiple light-emitting diodes, the following special parameters are required:

1. Luminous intensity ratio: Since each segment of the digital tube has the same driving voltage, the forward current of each segment is different, so the luminous intensity of each segment of the indoor LED display screen is different.

The ratio of the large value to the small value among the luminous intensity values of all segments is the luminous intensity ratio. The ratio can be between 1.5 and 2.3, and the maximum cannot exceed 2.5.

2. Pulse forward current: If the typical forward DC working current of each segment of the stroke display is IF, then under the pulse, the forward current can be much larger than IF. The smaller the pulse duty cycle of the indoor LED display screen, the larger the pulse forward current can be.
