电路板

Tip: In order to display the work efficiently, we must not lose sight of its environment, for example, can not be allowed to work in an environment of dust Dancer in the display when not in use dust mask must cover the display cover, or keep the dust attached to the display's internal components, circuit boards, which may affect the normal display of heat distribution, so that components, circuit board along with the rise in temperature to accelerate the pace of aging, affecting the life of the display.

小提示：为了能让显示器高效工作，我们千万不能忽视它的使用环境，例如不能让其工作在灰尘漫舞的环境中，在不使用显示器时必须用遮尘罩盖住显示器，不然灰尘不断地附着在显示器内部的元器件、电路板上，从而可能影响显示器热量的正常散发，以致于元器件、电路板随着工作温度的上升，加快老化速度，影响显示器的使用寿命。

All sales of equipment were free distribution reserve a circuit board, circuit boards free maintenance for life;整机problems within one year of free on-site service.
