LED Display Classification Introduction

With the rapid development of technology today, LED display screens can be seen everywhere in our daily lives, but they are mainly used for commercial and media advertising, large-scale conferences, sports events, cultural and entertainment activities, etc., such as the closing ceremony of the Pyeongchang Winter Olympics The ice screens of "Beijing Eight Minutes" are all types of LED displays. The LED display is composed of unit templates, and each unit template is composed of LED lamp beads. Faced with many wholesale LED display manufacturers, how should we choose? Let us learn how to choose LED displays. First, let us understand the classification of LED displays.

How to classify LED electronic display screens is roughly classified in the following ways:

(1) Divided by pixel density;

The pixel density of an LED display refers to the number of pixels per square meter, which is used to distinguish LED displays with different dot pitches. Generally, the smaller the dot pitch, the higher the pixels, and the better the displayed video effect.

Indoor surface mount pixels:

P1.56 full-color indoor LED display 409,600 dots/m2

P2 full color indoor LED display 250,000 dots/m2

P2.5 full-color indoor LED display 160,000 dots/m2

P2.6 full-color indoor LED display 147928 dots/m2

P3 full-color indoor LED display 111111 dots/m2

P3.2 full-color indoor LED display 97656 dots/m2

P3.3 full-color indoor LED display 91827 dots/m2

P3.91 Full-color indoor LED display 65410 dots/m2

P4 full color indoor LED display 62500 dots/m2

P4.81 full-color indoor LED display 43222 dots/m2

P5 full color indoor LED display 40000 dots/square meter

P5.95 full-color indoor LED display 28247 dots/m2

P6 full-color indoor LED display 27777 dots/m2

P6.67 full color indoor LED display 22478 dots/m2

P8 full-color indoor LED display 15625 dots/m2

P10 full color indoor LED display 10000 dots/m2

Outdoor screen pixel diameter and number of pixels

The pixel points of the outdoor display are the same as those of the indoor. At present, the minimum pixel of the outdoor LED display is P3.91, which is applied to the P3.91 full-color outdoor rental screen.

(2) According to display performance, it can be divided into;

Video display screen: generally full-color display, such as P4.81 full-color outdoor rental screen;

Text display screen: generally a single-color display screen, such as LEDP10 monochrome screen;

Graphic display: generally a dual-color display, also known as an LED dual-color screen;

Special display: generally the door head color, such as Led door head full color screen, using P13.33 outdoor surface mount module.

(3) According to the display device can be divided into;

LED digital display: The display device is a 7-segment digital tube, which is suitable for making clock screens, interest rate screens, etc., and digital display screens.

LED dot matrix graphic display: The display device is a dot matrix display module composed of many uniformly arranged light-emitting diodes, suitable for playing text and image information. For example, 3.75 indoor dot matrix monochromatic board, 5.0 indoor dot matrix monochromatic board, 3.75 indoor dot matrix two-color board, 5.0 indoor dot matrix two-color board.

LED video display screen: The display device is composed of many light-emitting diodes, which can display various video files such as videos and animations.

Conventional LED display: the steel structure is used to fix the display in one position. The main common ones are outdoor large single-pillar LED advertising screens, as well as single and dual-color LED display screens installed on the wall in the station to broadcast train information.

Special LED display: When designing, the R&D department took into account the different needs of the market and designed LED spherical display, LED mirror screen, LED cylindrical display and LED special-shaped display.

(4) Led display classification introduction-use environment

1. The semi-open air curtain is between indoor and outdoor, and has high brightness. In this case, it can be used outdoors. Generally speaking, the screen is sealed and used on the roof or window.

2. Indoor screen area will be relatively small and the price will be more expensive than outdoor screens, so they are generally very small (a dozen square meters). And the viewing distance is a few meters away, because it is indoors, so there is no need for the open air, and the screen body does not need to be sealed and waterproof.

3. The outdoor display area is usually relatively large, with a small area of more than a dozen square meters, and a large area of hundreds or even thousands of square meters. The dot density is relatively sparse and the luminous brightness is 3000-6000cd/square meter. In direct sunlight, the viewing distance is tens of meters. Because it is used outdoors, it is necessary to use a waterproof box to prevent uncertain bad weather. In general, we can distinguish from the above points!

The LED electronic display adopts low-voltage scanning drive, which has the advantages of low power consumption, long service life, low cost, high brightness, large viewing angle, long viewing distance, waterproof, and multiple specifications, which can meet various application scenarios. Demand and development prospects are very broad, and it is recognized as the most promising and fastest growing LED application market. In the future, new demands such as various large-scale sports events will promote the large-scale development of LED displays. In addition, the large-scale LED display screens that have been installed will undergo a wave of replacement every 10 years. With the improvement of people's living standards, outdoor LED display screens will gradually be used in various industries.
