The circuit board of the LED display is generally composed of a light board and a driver board. At present, there are two designs on the market, one is the integration of the lamp drive, and the other is the separation of the lamp drive. Many customers do not understand the LED display products using these two solutions, which is better and which is worse, do not know how to choose? The following Liancheng development small series (www.lcf-led.cn) to explain to you what is LED display lamp drive integration and lamp drive separation and what is the difference between them, for everyone to buy a display to make a reference.          
 

First, LED display light drive integration: the LED light and driver IC of the full-color LED display are all on a PCB board, the IC is on the front of the PCB circuit board, eliminating the copper plug, the advantage is that there is no inductance effect, no screen; The disadvantage is troublesome maintenance.

         

Second, LED display light drive separation: the LED light is on an independent PCB circuit board, the driver IC is on another PCB board, and the signal connection between the two PCB boards is carried out by the way of the pin and the bus to achieve the purpose of normal work.          
 

There are three main reasons for the separation of LED electronic display using lamp drive: First, the LED display uses plug-in LED, the LED foot affects the normal placement of the back driver IC, so the lamp drive separation method is used; Second, the point spacing of the LED display is too small, which affects the wiring of the PCB board in the electronic design, and the way of lamp drive separation can increase the wiring area of the PCB board; Third, it is conducive to heat dissipation without affecting the display effect of the LED display, if the lamp drive integration method is used, when the LED lamp density is very high, the heat of the driver IC will be high, and the heat of the driver IC will directly affect the LED lamp directly to the IC through the PCB, so that the color of the LED lamp will change. This is not the case with lamp drive separation.

         

Four, the comparison of lamp drive integration and lamp drive separation: from the cost point of view, the cost of lamp drive integration is slightly lower; From the maintenance point of view, the lamp drive separation method is easy to repair, because it can be replaced with each other to detect, and the lamp drive separation lamp is concentrated together, it is easy to change the lamp; From the heat dissipation point of view, the lamp drive separation is more conducive to heat dissipation.

         

To sum up: the scanning display screen in the general household uses the lamp drive integration is relatively more, saving costs; Most of the outdoor LED display adopts the way of lamp drive separation, which can well extend the display effect and life of the LED display. What kind of way to choose, according to the use of the environment and specific circumstances to decide.
