First of all, let’s get to know what an ordinary LED display is. Ordinary full-color LED displays are divided into indoor and outdoor led displays. They are usually fixed installations, because after installation, their position is generally not free after being fixed. Mobile, so some people in the industry call it a fixed LED display. The different stage rental led display is easy to install and easy to disassemble. It is convenient to transition, and you can freely match the height and width.
There is also the difference in the cabinet. The traditional ordinary LED Display Supplier are generally simple cabinets or waterproof cabinets, which are bulky and not suitable for disassembly. Relatively speaking, the LED rental screen uses a die-cast aluminum cabinet, which is simple and light, simple to install, light and thin in structure, and high in fixity.
For the most common concerts in our lives, many times, concerts will not be held continuously and continuously. Sometimes it may be once every half a month, and sometimes it may be used only once every half a year, and if a fixed The display screen is left there for a long time, which takes up space and wastes resources. If it can be easily disassembled, it can be disassembled and transferred to other stages or venues after use. It will not occupy space and can be used well. Resources are creating benefits, which is equivalent to having the best of both worlds.
Led rental screens generally choose different models according to the actual situation. For example, indoors generally use P3, P3.91, and P4 high-definition full-color LED displays. If it is some conferences, studios, etc. that require higher-definition displays, then full-color led displays such as P2 and P2.5 with smaller dot pitches will be selected. Like some large-scale concerts and stages, because the scene is very large, P4.81, P4, P5, P6 full-color rental LED displays with higher dot pitch will be used. Therefore, the choice of what kind of dot pitch display screen needs to choose different models according to the viewing distance, the size of the display screen, and the venue.
Six factors distinguishing the quality of rental LED displays
As the application of rental LED displays becomes more and more widespread, and related products are increasing, how to distinguish the quality of rental LED displays has become a problem that many customers want to know before buying. Next, Let us study hard together.
The flatness of the surface of the display
This is the most intuitive factor, whether professional or non-professional customers can see it most intuitively with their eyes. The surface flatness of the display screen should be within ±1mm, so as to ensure that the displayed image will not be distorted. If there are local protrusions or recesses, the viewing angle of the LED display screen will appear dead. At the same time, it is necessary to ensure that there is no gap between the module and the module during the installation process. Generally, the display screen below P3 needs to pay special attention to this problem during the assembly or installation process. If there is a gap between the module and the module, a black border will be seen during the playback of the screen
Brightness
The brightness of the indoor full-color screen should be above 800cd/m2-1200cd/m2, and the current brightness of conventional lamp beads can reach this level. Of course, the brightness is mainly determined by the quality of the LED lamp chip. Generally speaking, the quality of the lamp beads of NationStar is the best. Therefore, the brightness can also be increased to a certain extent. If the cost is limited, People can also consider choosing a crystal platform. The lamp beads, relatively speaking, the price will be slightly lower.
White balance effect
The white balance effect is one of the important indicators of the display screen, and many non-professional sellers do not know this parameter very well. For example, if everyone want to display pure white, then the ratio of the three primary colors of red, green and blue should be adjusted to a ratio of 1:4.6:0.16.
If the actual ratio is a little bit off, there will be a deviation in white balance, and this deviation will cause white to appear. The phenomenon of bluish or yellowish green. White balance is generally adjusted by adjusting the color resistance before mass production. Whether the white balance is well done or not has a lot to do with the craftsmanship level of the manufacturer.
This is also an important level to measure the strength of the manufacturer. If the customer finds such a deviation in the stage rental LED display products produced during the inspection on the site, then it means that the strength of the manufacturer is very limited, and priority can be given to JYLED This kind of powerful manufacturer with more than 10 years of production experience.
Color reproducibility
Color reproducibility refers to the reducibility of the display screen, which means that the color displayed on the display screen must be highly consistent with the color of the playback source, so as to ensure the realism of the image.
So, does it mean that the smaller the dot pitch, the better?
Senior engineers of JYLED told us that the dot pitch does not mean that the smaller the better, it should be decided according to the actual application. For example, a large outdoor full-color LED display screen. Because of the visual display distance, a display device with a relatively large spacing is usually used. Generally, the dot spacing is larger than that of P3. Usually P3.91, P4, P5, etc. are used. For users who need detailed display screens, such as security control, a smaller dot pitch of full-color small-pitch LEDs will be more appropriate.
If the dot pitch is relatively close, for example, it is difficult to choose between P1.875 and P1.667, people can choose the right product from many aspects such as people budget, viewing distance, and image quality requirements.
Whether there are dead spots
Dead point refers to a single point that appears on the display screen that is always on or black. The number of dead points is mainly determined by the quality of the lamp beads. Generally, the problem of large quantities of dead lamps will not occur with the use of braided genuine lamps. There are also some dead lights because of virtual soldering during patching.
Whether there is a color block
Color block refers to the obvious color difference between adjacent modules. The color transition is based on the module. The color block phenomenon is mainly caused by poor control system, low gray level, and low scanning frequency. The small-pitch LED display is more prominent on this issue.
The above points are not only to judge the quality of the full-color rental LED display, but also an important criterion for judging the strength of the manufacturer. For those who operate irregularly and substandard LED display manufacturers, although the price may be relatively cheap, the quality is More worrying.
To understand the selection criteria of LED displays, let’s look at a problem that many customers are more concerned about, that is:
The difference between full-color rental LED display P2 and P3
Many users often don’t know much about the professional terminology of LED displays when choosing a customized full-color rental LED display. As an LED display device, the first hurdle is the dot pitch of the screen. So let’s understand the difference between displays with different dot pitches.
Generally, we use the English letter P to indicate the dot pitch of the screen. P comes from the English word Point, which means a point, where it represents the distance between each point. The unit of LED display dot pitch is mm (millimeter). As the name implies, the P2 full-color indoor LED display device indicates that the distance between the center points of the lamp beads is 2mm.
After understanding this key point of knowledge, for P2 and P3 full-color LED displays, we can naturally know that P3 is an LED display with a dot pitch of 3mm, and similarly, P2 is an LED with a dot pitch of 2mm. Display screen. Therefore, under the same screen area and model, P2’s display dot pitch is smaller, so the displayed image will be more detailed and high-definition. At the same time, the smaller the distance between points, the higher the production cost, and therefore the more expensive the price.
So, does it mean that the smaller the dot pitch, the better?
Senior engineers of JYLED told us that the dot pitch does not mean that the smaller the better, it should be decided according to the actual application. For example, a large outdoor full-color LED display screen. Because of the visual display distance, a display device with a relatively large spacing is usually used. Generally, the dot spacing is larger than that of P3. Usually P3.91, P4, P5, etc. are used. For users who need detailed display screens, such as security control, a smaller dot pitch of full-color small-pitch LEDs will be more appropriate.
If the dot pitch is relatively close, for example, it is difficult to choose between P1.875 and P1.667, people can choose the right product from many aspects such as your budget, viewing distance, and image quality requirements. Can.
Precautions for storage of full-color rental LED display
Many times after we buy the led display, because of some factors, we cannot install it immediately or need to disassemble the product for storage after the concert. As a sophisticated electronic product, the LED display has high requirements on storage methods and environment. Carelessness may cause damage to the LED display. Today we are standing in the professionalism of LED display manufacturers. From a perspective, how to properly store full-color rental LED displays.
We need to pay attention to these 8 points when storing led display screen manufacturer:
1. After cleaning the place where the box is to be placed, use pearl cotton to lay it.
2. It is strictly forbidden to stack modules in disorder or stack more than 10 pieces of LED display. When the modules are stacked, the lamp surfaces are placed relative to each other and separated by pearl cotton.
3. It is recommended to place the LED display box with the lamp facing up. If there are too many, people should pay special attention to protection when everybody need to place it upright. It is not allowed to place it upright in places with high vibration.
4. The display box body should be handled gently. When landing, the back side first touch the ground and then the lamp surface, beware of knocks.
5. All staff must wear a cordless anti-static wristband when installing or repairing.
6. Use an anti-static wristband for LED display installation
7. When carrying the box, it should be lifted, and it should not be pushed or towed away on the ground, so as not to damage the bottom module due to uneven ground. The box body should be balanced during the lifting process, and should not swing or rotate left and right in the air. When installing the cabinet or module, handle it gently, and don’t throw it.
8. If the LED display product needs to be adjusted, use a soft rubber hammer to hit the metal part of the box, and it is strictly forbidden to hit the module. It is strictly forbidden to squeeze or collide between modules. In the case of gaps, abnormal positioning, etc., it is strictly forbidden to use hammers and other hard objects to hit the box and module. Everyone can pick up the box and try again after removing foreign objects.
