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.

How to Use Notebook System to Control LED ad Screen

Senior technical personnel in general LED display industry all know, LED advertising screen to show the performance and effect is high, but for the convenience of control LED screen control system should have input and output interface and remote communication function is enough. The system structure of our LED based ad screen controller based on HDMI1.3 technology. The system can be divided into 6 types: analog input, 1 way VGA input, 2 DVI input, state indication, real time clock, and optical fiber data transmission model.
At present, the LED advertisement screen mainly has two kinds of synchronous display and off-line display according to the data transmission mode. LED advertising screen control this is a synchronous display system, which uses a set of embedded system for LED screen video source, which can reduce the cost, but also has feasibility and high flexibility, easy construction. Independent video LED advertising screen system is completely out of the control of the computer, and it can realize communication, video playback, data distribution, scanning control and other functions. Since the controller is controlling the large frame data, it is necessary to allocate the data provided by the video source, and send the data from different ranks into different controllers.
The data correction module receives the input data from the front end and stores the data by point by point correction, and then stores the data in SDRAM. The field data is then divided into 8 groups and sent to the LED ad screen distributor at the same time.
FPGA according to the timing relationship, the input data is read into the next step. Because the parameters of the LED advertisement screen can not be exactly the same in the process of production, the LED tube must be filtered to obtain good image display effect.
When the data is assigned, the signals are transmitted in the form of LVDS. Because this system uses MCU+FPGA structure, thus realizing network remote operation of the real, not only can be used as a LED screen controller, the display will be more nodes to form a large outdoor advertising media network. According to HDMI technology to control LED advertising screen, the brightness is appropriate, the use of fine resolution, high field scanning frequency, high pixel, can be used for outdoor broadcast level applications. The design through single point correction, which allows buyers to relax the LED in brightness and color requirements, and related procurement costs will also be reduced.
