The circuit board of LED display is generally composed of lamp board and drive board. There are two designs on the market at present, one is the combination of lamp drive, the other is the separation of lamp drive. Many customers are not very familiar with the LED display products using these two solutions, which is better or worse, and do not know how to choose? The following united LCF editor(www.lcf-led.cn) to explain to you what is the LED display lamp drive and lamp drive separation and what is the difference between them, for you to buy a reference screen.

1, LED display lamp drive in one: full color LED display LED lights and drive IC are all on a PCB board, IC is in the front of the PCB board, eliminating the copper plug, the advantage is no inductance effect, no screen;  The disadvantage is the trouble of maintenance.

2. LED display lamp drive separation: THE LED lamp is on an independent PCB board, and the drive IC is on another PCB board. The two PCB boards are connected by means of pin and bus plug to achieve the purpose of normal operation.

3, LED electronic display lamp drive separation mainly for three reasons: first, LED display is plug-in LED, LED lamp foot affects the back of the drive IC normal placement, so the lamp drive separation mode is used; Second, the point spacing of LED display screen is too small, which affects the wiring of PCB board in electronic design. The way of lamp drive separation can increase the wiring area of PCB board. Third, conducive to heat dissipation without affecting the display effect of LED display, if the lamp drive in one way, when the LED lamp density is very high, the heat of driving IC will be very high, at this time the heat of driving IC will directly affect the LED lamp on IC through PCB, so that the COLOR of LED lamp changes. This is not the case with lamp drive separation.

4, the combination of lamp drive and lamp drive separation comparison: from the cost point of view, the cost of the combination of lamp drive a little lower; From the maintenance point of view, the lamp drive separation is easy to maintain, because it can be replaced with each other to detect, and the lamp drive separation lamp concentrated together, it is easy to change the lamp; From the heat dissipation point of view, lamp drive separation is more conducive to heat dissipation.

To sum up: the general indoor scanning display lamp drive relatively more in one, cost saving; And most outdoor LED displays adopt the way of lamp drive separation, which can well extend the display effect and life of LED displays. What kind of method to choose, according to the use of the environment and the specific situation to decide.
