Plug-in module
Refers to the encapsulation of DIP lamp will light feet through the PCB board, the tin filled in the lamp hole welding, LED display module made by this process is plug lamp module; has the advantages of large angle, high brightness, good heat dissipation; the disadvantage is the small pixel density.
Surface mounted module
Surface mount is also called SMT, the encapsulation of SMT lamps by welding on the surface of the PCB plate, light feet not through the PCB board and the advantages are: wide view, display image soft, pixel density, suitable for indoor viewing; the disadvantage is that the brightness is not high enough, the radiating tube is not good enough

P5-32x32-8scan (2)
Sub surface mounted module
Is a product between DIP and SMT, the LED lamp package surface and SMT, but its positive and negative pins and DIP, production is through PCB welding, LED screen module has made this kind of process is: high brightness, good display effect, the shortcoming is: complex process maintenance difficulties.
Three in one SMD
Refers to R, G, B three different colors of LED chip packaged in the same colloid, the advantages are: simple production, display effect is good, the drawback is: split color separation difficult, high cost
Three abreast to one SMD
Refers to the R, G, B three independent packaging SMT lights in accordance with certain spacing perpendicular together, so that not only has three in one all the advantages, but also to solve the three in one of the shortcomings
As can be seen above, these 5 different LED screen modules have different advantages and disadvantages, so when you customize the LED display, you should choose according to the actual application and the scene.

Stage LED display
The new LED dance floor refers to the new stage form that combines the creative LED screen with 3D and other dynamic light and shadow display technologies, such as the transparent LED display screen and the stage effect, which are distinguished from the conventional LED display screen stage effect. The appearance of the new stage rental screen makes the stage’s style of expression more colorful, giving people a colorful visual eye, and interpreting fantastic beauty of light and shade. In choosing the new stage rental led screen manufacturers, we should pay attention to the following aspects:
First of all, depends on the strength of manufacturers. Factory strength represents many aspects, including its registered capital, site size, R & D strength, staff team, production capacity and other aspects, they are a symbol of enterprise strength brand. Powerful enterprises, large companies means better market reputation, the quality of their products as well as guaranteed after-sales service.

Second, the price of the products depends on the price. Price is the core of the most widespread concern among users, because everyone likes to buy products of high quality and low price. The user can select several manufacturers to compare prices, but do not need to blindly down prices, as the saying goes, no good cheap goods, the price is too low, the majority of product quality is also not so good, after all, the enterprise can not be a fool. Optokingdom here suggested that users can combine the project budget, select the appropriate stage rental screen manufacturers, so as to better promote the project’s economy, effective implementation.
The last thing to look at is technology. The choice of LED dance floor manufacturers not only to see the strength of the manufacturers and the price, still need to see whether manufacturer of patent technology, project implementation experience is mature, take the hand of many successful cases, the reputation of the industry is good, what are the advantages compared with similar manufacturers, the implementation of the project is stable? In general, the LED dance floor manufacturers advanced technology have rich project experience, and can help users to reduce many problems in the implementation of the project installation and customer service process, more time can be avoided and the unnecessary expenditure of funds.

Common LED Display Cabinets VS Waterproof LED Display Cabinets

What is the difference between common LED display cabinets and waterproof LED display cabinets ? How to choose between these two kinds of cabinets ? We believe that many of us don’t know the answers of these two questions. Because of the influence of the wet rainy weather, we usually use waterproof cabinets on outdoor led displays. on the contrary, indoor environment asks less for waterproof requirements, so it is better to choose simple cabinets when we design indoor LED displays. But how to distinguish between them is another question. Optokingdom would like to offer some information about it for you.

common LED display cabinets and waterproof LED display cabinets

The difference between common LED display cabinets and waterproof LED display cabinets on the aspect of structure is that : there are no back doors and fans on simple cabinets. The advantages of common LED display cabinets are reduced weight and reduced cost.

Edge–Wrapping is an essential process for both simple cabinets and waterproof cabinets. Simple cabinets that apply stainless steel edge–wrapping process have simple structures, at some level, they can be designed to be waterproof. Waterproof cabinets are fully sealed up so they are able to keep dry under the normal outdoor rainy conditions.

More and more people now apply simple cabinets even when design outdoor led displays because the cost of waterproof cabinets is very high and some simple cabinets can be designed to be waterproof as well as waterproof cabinets.

The trend of cabinets designing seems develops towards“thin”and “easily–disassemble”. But from a professional point of view, “fully sealed up”and “thin”doesn’t always means perfect. We can take the example of your computer machine box, the cabinet structure only make it dust proof, once plenty of water comes in, internal damage will definitely happen. On the other hand, it is not conducive to dissipate heat in a small space.

How to Solve Outdoor Monochrome LED Display Garbled

How should we do when Monochrome LED display appear unintelligible text ? Some outdoor display in the process of use, especially outdoor walk word monochrome LED display, there will be unintelligible text appear. how to solve?
1. Leakage water problems
First of all, the LED screen appears unintelligible text, mostly related to leakage, due to improper rain protection measures, water immersion after rain. Cause short circuit board, and then form garbled. If this happens, build a vendor and repair it immediately.
2. Transmission data problems
The control circuit of the brain output to the screen is out of order, focusing on the screen power supply and signal input section. Like the control system board damage, data line interface damage, data line damage, and so on, will cause outdoor screen garbled.
3. Cable problems
In case of power failure, test whether the power supply of the defective module is normal (if the abnormal first piece is dark and 80% is the power supply problem)
4. Software or control card problems
LED display parameters are not set up, this time you need to determine the scanning configuration problems, usually 1/4 sweep; if not software problems, check the control card problem; and then make it bad, only contact service providers to solve.

The Most Common Four LED Screen Assembly Method

LED display screen assembly is a complex and tedious process, and each link requires engineering and technical personnel have excellent professional skills, to be able make LED display products do precisely and fine. Insiders know that the LED display is composed of many modules which are spliced, and the module is assembled by many beads. In the LED display assembly process, assembly steps ring after ring, ring must be careful, otherwise it will affect the LED display effect. In order to meet the requirements of large area, high brightness and dynamic display screen of LED display, as well as matching drive requirements of LED driver. The following describes the four types of LED display connection form:

OFSE4-002
1, the whole screen of LED display screen series: general assembly simple series connection in LED1-n, end to end, is equal to the current through LED display work. The other is an improved method of 1.1 with series connection with bypass.

2, LED screen whole screen parallel assembly method: one is simple parallel form, and the other is independent matching parallel form. The LED1-n in a simple shunt is parallel to each other, and the voltage on each LED is equal when operating. The reliability is not high, but also for the issue of parallel form, independent, with good effect, single LED display driver to protect the integrity, failure does not affect other work, can be matched with different characteristics.

OFSE5A-50
3, LED display cross array assembly mode: cross array shape, mainly in order to improve the reliability of LED display work, reduce the failure rate raised.
4, LED display mixed assembly method: appeal by parallel and series of advantages put forward by each other. Also includes 2 kinds. One is the combination of the first and the subsequent, and the other is the combination of the first and the subsequent.
The above four type LED display, assembly, connection, each has its advantages and disadvantages, according to different applications, choose the most suitable LED display connection. Many engineering people tend to ignore this, leading to a variety of connection faults in the LED display, which ultimately affect product quality and reduce user confidence. Thus, the assembly of the LED display, details determine success or failure!

Whether Indoor LED Screen Can Change to Outdoor Use or Not

Recently optokingdom Mr Cen met customer consultation, said his indoor LED display used for a period of time, now want to change to use in outdoor environment. asked that if he can change the indoor led screen to the outdoor LED screen directly? To solve this problem, we answer the following questions for our clients:
First of all, this is definitely not changed, the main reasons are as follows:
1. Brightness limits. Indoor LED screen brightness requirements are not high, using a dynamic scanning circuit, outdoor led screen brightness higher, static scanning circuit, the hardware difference between the two. Dynamic scanning is actually in order to save hardware cost and use, with the driver chip number is more than ten times, determines the indoor display brightness is relatively low, generally 1500cd/ square meters or so, only suitable for indoor use.
2. Waterproof limits. Indoor screen structure does not require simple waterproof or water treatment, and outdoor LED display high waterproof requirement in production when the waterproof treatment of cable and the box, so in the box structure itself requires a difference.
3. Viewing distance limit. Indoor LED display viewing distance is generally P3 P4 P5 P6 model, so the area is generally small, in 15 square meters, while the outdoor LED display requirements viewing distance is more far away, the model is generally P10 P16 P20, so it decided it’s area much larger, more than 30 square.
In a word, the indoor and outdoor LED display screen because of its brightness, water-proof treatment, selection of different models, resulting in the different from start of production, raw materials, accessories, cabinet and other hardware , so it is not good to change, change will only The loss outweighs the gain. You’d better to buy another one outdoor led display.

Why Rental LED Screen Are So Popular?

LED screen rental is a dedicated stage performance and recreational activities LED screen. Usually this kind of LED screen appears in the form of rental screen, so it is named as LED screen rental.

LED screen rental is widely used in stage screen rental, dancing party, all kinds of new product announcement conference, exhibition, stadium, theater, hall, lecture hall, multi -function hall, conference room, interpretation hall, night club, high-level discotheque, etc. Comparing with traditional fixed screen, LED screen rental has following advantages:

Lightweight, ultra-thin

The cabinet of traditional LED screen is made of SPCC(cold rolled carbon steel board), which is also known as “iron cabinet”. The cost of the iron cabinet is quite low, but it also has a shortage: the cabinet is too heavy. The average weight of each square meter of finished LED screen is above 45kg. Stage performing arts industry usually use the LED screen in aluminum cabinet. The average weight of each square meter of aluminum cabinet LED screen is 20~30 kg, which is much lighter and the thermal conductivity is much better than iron ones.
576x576-p3 (2)
Small errors,  seamless joint

Because of the sheet metal processing method of traditional LED cabinet, which the technology errors is quite large, and the iron cabinet can be easily deformed after reprocessing, the error is in degree of millimeter. So it is quite difficult for traditional cabinet to meet the requirements of seamless
joint of the screen.

The aluminum cabinet of LED screen rental uses module forming, combined with the machining process. The error can be controlled in 1 millimeter, so the aluminum cabinet can fully meet the requirements of seamless joint.
indoor rental

Quick Installation

Since the cabinet is made of aluminum structure, so the weight is lighter, the precision is higher, the dismantlement is more convienient. The technicians can easily splice cabinets in a few minutes. Using the aluminum cabinets can greatly reduces the installation and dismantlement time, lowers manpower cost.

Long service life

The main component that affects the LED screen service life is the light emitting diode, and high temperature is its biggest killer. With the excellent heat dispersion, aluminum cabinet can provide a more stable ambient temperature,that would help to largely extend the LED screen life-time.

Our products are equipped with various flight cases, which are not only provide good protection for the rental LED screen screen, but also the easy storage and transportation.
package-and-service
LED rental display is very light, and its structure is quite thin, and it also has the lifting and quick installation functions. So that it can meet the requirements of quick installation, dismantlement, transportation according to the situation of rental space. The whole LED screen screen can be quickly fixed and connected by bolts. The technicians can accurately install and uninstall the exact LED screen. The LED screen module can be spliced into different shapes according to the requirements of the field.
With its unique welding process optimized structure design, field failures which are usually caused by loose contact of welding points which is result from  frequently movement, can be widely avoid.
With the improvement of people’s living standards and the pursuit of art and culture enjoyment, the entertainment industry and health-sport industry are flourishing. Rental LED screen plays an important role in the whole LED screen industry, and with the expanding market, we believe that the market of rental LED screen will continue to grow in high speed…

Solution For Text Overlap Of LED Display Screen

The LED display text overlap is a suck thing, especially for banks, large shopping malls such people more places, special experience is not good, how to solve the influence of the image;  How is LED display text overlap going on?
The most common problem description: a length of 3.84M, width of 1.44M P10 outdoor LED display, installed after the direct delivery of customer use, customers also did not carry out full screen testing. One day, customers send more content, and the text displayed on the whole LED screen is more comprehensive. However, it is found that the third lines overlap with the font of the fourth line (or that the upper part of a word can be displayed normally and that the lower part cannot be displayed, and that the word is displayed across the third line and the fourth line)
Terms of settlement:
1, first check whether the power connection is loose and fall off
2, check the cable is inserted firmly.
3. Check the corresponding relationship between the module and the connecting board
4, the output of the transit board
Ideas are as follows:
Through the step 1, 2 if not solve the problem, go directly to step 3, because the adapter plate connection sequence and module is one-to-one correspondence, discovery module just start from the fourth row, do not correspond to the fourth line module received fifth pin adapter plate, after the module in this push, restoring the connection relation. Steps 1, 2, and 3 make sure that there is no problem, but the text overlap is still unresolved, and then go into step 4, adjusting the panel output problem.
In addition, the initial use of led display process will appear overlap phenomenon , followed by steps 1, 2, 3, 4 to check the erro;  if the screen had been used for some time then appear overlap phenomenon, check 1, 2, 4 steps in turn; even can not solve the problem, contact the led display manufacturer or service provider.
