How to choose an LED display

/in /by

LED display screens have been seen everywhere in people’s daily life, so when you need to buy LED display screens, you need to consider some factors?

According to the environment, LED displays are divided into indoor LED displays, outdoor LED displays, semi-outdoor LED displays.

LED display screens are divided into colours: full-colour LED display, dual-color LED display, monochromatic LED display.

LED displays are divided into outdoor advertising LED display, rental performance LED display, indoor conference LED display, interactive LED floor display, spherical LED display, transparent LED display, car LED display, light pole LED Display screen.

LED display screens are divided according to the model indoor: P0.976, P1.25, P1.56, P1.667, P1.923, P2, P2.5, P3.0, P3.91, P4, P4.91, P5, P6, P7.62, P10 indoor full-colour LED display.

According to the model size, the LED display is divided into P2.5, P3, P3.91, P4, P4.91, P5, P6, P7.62, P10 outdoor full-colour LED display.

Currently, we use the most full-colour LED display indoor and outdoor. How to choose a suitable LED display?

Dot spacing: the distance from the center of the lamp bead to the center of the lamp bead is called the dot pitch, in mm (millimetres). First, you need to select the viewing distance. Take p4 as an example. The best line of sight distance is 4 meters or more. It requires observing the closest viewing position from you to determine which model to choose. (Common for indoor and outdoor large screens)

Specific size requirements: You need to know the specific parameter values, such as length and width, actual size, size is divided into display size and actual hemming size, the display area size is smaller than the actual hemming size.

Here to talk about the LED display module: the module’s size is uniform, so when you give the manufacturer the size, the actual area will be larger or smaller than the size you give. For example, p4 module size is 256mm * 128mm, p3 size 192mm * 192mm, p5 size: 320mm * 160mm, the manufacturer will calculate the actual display size according to the situation.

Example: To make a P4 4 * 3 meter LED display (actual size), the display area length is: 4 / 0.256 = 15.625 take one, 15 * 256 = 3.84 meters, width 3 / 0.128 = 23.44 take the integer 23, 23 * 128 = 2.944 meters. The actual display area is 3.84 * 2.944 = 11.3 square meters, plus the edge size is close to the actual size of 4 * 3 meters. The actual size is 4 meters * 3 meters = 12 square meters, the display area will be less than 12 square meters.

The price of outdoor and indoor LED displays is different. Indoor LED displays are attracted by magnets, mainly from the front. Compared with the indoor LED display, the outdoor LED display is much more complicated in the production process. It needs to be IP65 dustproof and waterproof, and the electronic components generally operate under high and low-temperature conditions. The indoor LED display module on the outdoor LED display has high brightness and needs high-brightness lamp beads; the outdoor module uses waterproof glue on the PCB board, the cabinet is waterproof, and the outside is the exterior. In extreme environments, it must add Air conditioning, which inevitably raises the price of outdoor LED displays.

When purchasing products, you also need to understand the strength of the supplier. There will always be a small problem when the product is right. At this time, you need a well-reputed supplier to give you high-quality service. A high-quality supplier has attentive service and an after-sales team. To save customers worry and effort, this is the right LED display supplier.

One of my overseas floors led display shopping experience

/in /by

I am in the United States, and my name is Jacy. We have a performance hall. The stage has a rental LED display background. Recently, we plan to consider buying LED floor display for stage performances. The boss hopes that the dance will be more atmospheric and beautiful. When the camera is shooting, only the LED background on the stage increases the viewing effect, so I want to buy a display screen displayed on the ground.

Due to the recent epidemic in the United States, it is challenging to buy many products; life is worrying! Many supermarkets here are closed, many restaurants are also closed, let alone buy better electronic products. The US epidemic is indeed too difficult! The number of employees and performances in our stage art industry is also decreasing day by day, so it is essential to increase the stage’s dynamic fashion effect. The conventional stage rental LED display in the United States is easy to buy. However, the cost is relatively high, and the display quality is still inferior. I have visited many manufacturers. I heard that the cost is still very high. I heard a friend say by accident: “Why don’t you have to think about buying abroad. There are many LED electronic products in China. Especially in Shenzhen, the world’s LEDs look at China, and the Chinese LEDs look at Shenzhen! Their LED display effect is good, and the cost is meagre!” I felt overjoyed and found new hope!

But we have never bought LED electronic products abroad. We are anxious about the quality of the products. Will we encounter scammers? What is the quality of Chinese factory service? If there is a problem in one of these problems, then I will lose a lot. Later I found a friend named Antaki, who often buys products in China. And I asked him to introduce several Chinese manufacturers specializing in producing interactive LED floor tiles. Finally, I was fortunate enough to meet Creuview manufacturers. Scott has 12 in the LED display industry. Years of experience specializing in the production and development of LED displays. Especially in interactive floor LED display screens, it has its advantages and is independently developed by itself!

To buy a satisfactory Floor LED display, the display effect is stable and precise. We compared a few at the beginning and asked them to send in the floor tile LED display modules for testing. The products include acrylic masks, tempered glass masks, and It is Scott’s professional interactive LED floor tile screen kit. After comparison, we unanimously agree to use this interactive LED floor tile screen kit and module. 2. Some companies can only accept renminbi and can only enter individual Chinese personal accounts. The remittance fee is expensive; some companies have overseas corporate bank accounts, which can directly accept US dollars. The remittance fee is low; whether there are overseas bank collection accounts is also correct. It is also significant for us. 3. The company’s service quality can meet the installation and debug of interactive LED floor tiles. In the final comparison, we chose Creuview to cooperate, signed the contract, transferred the advance payment, and paid the final payment after production!

Outdoor led display screens are faced with the following problems before they are installed and used. These problems must be dealt with for led display screens to operate safely.

1. The led display screen is installed outdoors, often exposed to the sun, rain, wind and dust, and the working environment is harsh. Electronic equipment getting wet or severely damp can cause short circuits or even fire, cause failures or even fires, and cause losses.

2. The led display screen may be attacked by vital electricity and magnetism caused by lightning.

3. The environment temperature changes significantly. When the outdoor LED display screen works, it will generate a certain amount of heat. If the ambient temperature is too high and the heat dissipation is lacking, the integrated circuit may not work correctly or even be burned, making the display system unable to work usually.

Fourth, the outdoor led display has a broad audience, a long viewing distance and a wide field of view; the ambient light changes significantly, especially if exposed to direct sunlight.

The above are the unique requirements of an outdoor led display. Given these characteristics, the following editor summarizes some points for attention of outdoor led display.

1. The screen body of the led display screen and the joint between the screen body and the building must be strictly waterproof and leak-proof; the screen body must have reasonable drainage measures, and once accumulated water occurs, it can be discharged smoothly.

2. Install lightning protection devices on led display screens and buildings. The display screen and the shell’s main body are well-grounded, and the grounding resistance is less than 3 ohms.

3. Install ventilation equipment to cool down so that the outdoor led display’s internal temperature is between -10°C and 40°C. An axial fan is installed on the top of the back of the screen to discharge heat.

4. Use industrial-grade integrated circuit chips with a working temperature between -40°C and 80°C to prevent the low temperature in winter from causing the LED display to fail to start.

5. To ensure long-distance visibility under healthy ambient light conditions, outdoor LED displays must use ultra-high-brightness light-emitting diodes.

Sixth, the display medium of the led display uses a new wide-view tube with a wide viewing angle, pure colour, consistent coordination, and a life span of more than 100,000 hours. The outer packaging of the display medium is currently the most popular rectangular tube with a cover, sealed with silicone, and no metalized assembly; its appearance is exquisite and beautiful, sturdy and durable, with protection from direct sunlight, dust, water, high temperature, and circuit short circuit “Five defences” features.
