本發明的較佳的實施例中，如上文中所述，不同的PWM訊號的占空比代表不同的亮度等級，占空比的取值範圍可以預先設定，例如從最小值0到最大值1：當PWM的占空比為0時，表示全彩發光二極體燈珠在一個時鐘週期內全部的時段都是處於關斷狀態；當PWM的占空比為1時，表示全彩發光二極體燈珠在一個時鐘週期內全部的時段都是處於導通狀態，即為亮度等級最高的顯示效果。 In a preferred embodiment of the present invention, as described above, the duty ratios of different PWM signals represent different brightness levels, and the range of duty ratios may be preset, for example, from a minimum value of 0 to a maximum value of 1: When the duty ratio of the PWM is 0, it means that the full-color LED lamp bead is in the off state all the time in one clock cycle; when the duty ratio of the PWM is 1, it indicates the full-color LED The body bead is in the on state for all the time periods in one clock cycle, that is, the display with the highest brightness level.
本發明的較佳的實施例中，上述對于全彩發光二極體燈珠的亮度調節，需要對每路的最大電流輸出進行限流，以使最大驅動電流與全彩發光二極體燈珠的最大工作電流相配，以防止驅動電流過大造成驅動電路和燈珠過熱而燒毀。 In a preferred embodiment of the present invention, the brightness adjustment of the full-color LED lamp bead needs to limit the maximum current output of each channel to maximize the driving current and the full-color LED lamp bead. The maximum operating current is matched to prevent the drive circuit and the lamp bead from overheating and burning due to excessive drive current.
