A LED screen comprises of a case, a main board and a number of LED display modules. The case consists of a front surface, a back surface and an opening between the front and the back surface. The front surface has one window, the main board gets inserted in the case from the opening, where its front surface can be viewed from the window. Each LED display module has a LED display unit, a PCB driving board and a base for supporting it. The scope of LED screens is huge in terms of branding and advertising, can be used for creating publicity or other promotional activities, they are much more beneficial than the indoor static ones since they are portable and can be used in all sorts of conditions and environment.
The target audience can greatly increase with the use of LED display screen due to its high visibility and size. Its use in outdoor events such as tournaments can bring the audience to live events rather than using their television sets for it. The LED screens have a lot of electronic elements inside hence access to the interior is very important which is available in the form of Front Access LED Display, and Rear Back LED Display to ensure the correct type of maintenance. They can be used for video-conferencing, in studios, for meetings or anywhere to increase the efficiency of the meeting.
Front Access LED Display
The front access design of LED display makes the LED panel available from the front, which makes it suitable for locations where there is little to less space available for maintenance. This module also makes it easier and faster to assemble and disassemble the screen, which can save a lot of time and labor cost. With the front access LED module, you just have to find the fault module and fix it from the front directly. In installations where the screen is placed on a wall or façade one must use front access LED display otherwise the access to the system would be very time taking and tedious. The frontal maintenance can be carried out in three ways i.e. through a lock mechanism, magnetic system and a system with front screws.
A new improvement of this model has been the one offering double maintenance i.e. via both frontal and rear doors. This allows greater flexibility which allows the user to access the fault bilaterally with no need for specific placements. The ability to access the system through both the front and rear the maintenance becomes easier further regardless of the positioning of the screen.
Since the screen isn’t very thick it makes the LED display extremely light and non-invasive. The screen is specifically designed and tested to work under any weather conditions, the brightness being handled automatically is another factor which ensures maximum visibility and also prevents visual fatigues even after long hours of usage with a huge reduction in the energy consumption. The whole software design of this system allows easy composition of LED billboards of almost every size.(Want to know how to make money with led billborad?)
Rear Back LED Display
The screen and rear maintenance has door-like openings to access the interior. This system is fairly common and we see it in a lot of indoor and outdoor led screens, however if it is being used outdoor the placement of the door to access the system should be in a way that it prevents water leakage. The rear back LED display model makes it difficult to locate the fault module and you’ll have to spend a lot of time in trying to find the fault and then fix it. The cabinets are most commonly made up of steel but aluminum is also often used, however the cabling isn’t visible from outside in both the cases and the rear access can be made through a door which uses a key. The cabinets are also equipped with thermostat fans for temperature control and high performance switch supplies.
The only significant difference between front access LED display and rear back LED display is the amount of access they provide in which case the frontal access is easier and does not require a lot of labor and is also less time consuming when they are placed on a wall as far as the back access is concerned it is easier in the case of standing systems and the billboards etc. however a much newer technology exists which makes it possible to access from both the front and back and hence provides the features of both and works better under all conditions. The front access LED display is a much newer technology and more sustainable in terms of its life, ease of use, led display energy consumption, overall maintenance and labor costs and various other attributes.
