Training on components of scRolling/ribbon/caption led board

nowadays, LED SCROLLING BOARD assumed as one of the major tools and key medium for advertisement as it has several capabilities and located at several building facades
In this article we are going to introduce the necessary parts to build LED SCROLLING BOARD

         
For construction SCROLLING LED BOARD or urban TV we require such components asLED modulescontroller board   of SCROLLING BOARD, power supply of SCROLLING BOARD, frame (frame of SCROLLING BOARD), and so on

SCROLLING BOARD Module

LED module is as the most significant component of the LED SCROLLING BOARD at the same time to specify the quality of it and urban TV as well. the main application of the module is data receiving from controller card (mother board) and text or image displaying via illumination of each LED at intervals .The quality of LED Module depends on such factors as: the type of the chip used in the LED, addressing range of the module, LED IC module, , plastic frames used in LED module structure and LED mask so low qualities of these variables cause lifetime of LED module and a high percentage of failures in the SCROLLING BOARD module

:SCROLLING BOARD Power supply

Power supply is one of the crucial elements in the SCROLLING BOARD as the activity of other elements depends on the power supply function. In fact this part provides  electricity or power to operate other components of LED SCROLLING BOARD .the voltages equal to 5, 12 and … are common. The main feature of a power supply of LED SCROLLING BOARD is watt indicated by W. W equals to voltage (in volts) multiplied by the current (measured in amps).  The key role of thepower supply is transforming or converting AC voltage to DC voltage
Most failure rate in LED SCROLLING BOARD (compared to other parts) is relevant to power supply since as soon as the component to be turned on, the power supply operation will be started (heating/warming) while as the system is turned off, the power supply application shall be ended cooling  Considering the frequency of such operations and power voltage fluctuations, the power supply play a key role as the principal and primary FACTOR OF THE DEFECTS IN THE LED SCROLLING BOARD or urban TV. Being Sensitive to the smell of burning and ensure proper functioning of the cooling system of the power supply is the easiest way to specify and prevent failures in it.

:Controller board of SCROLLING BOARD

To select the controller, the color of LED module (single color LED Module or Full color LED Module) and the board dimension (number of rows and columns of the scrolling board) should be considered. As each controller, depending on the design, is capable of supporting a certain number of modules so the output (playback effects, texts, and pictures or images) will be different accordingly.
