DLP9500: DLP9500的可靠翻转频率

Part Number: DLP9500


根据手册,DLP9500的刷新频率由   数据传输+ Global Rsts  。如刷新200行,则200*16*1/400 + 4.5 = 12.5us  ,则可以设置为80K的刷新率。

我的问题是 ,实际DMD可以按照这个理论的极限值长期工作吗?若不可以,有没有一个长期稳定工作的推荐值。谢谢!

  • 根据DMD规格书,switching time 是13us, ( mirror settling time + reset time(crossover time)

    Global Mode:  load time是43.2us.

    因此global mode(without Load4)pattern rate 是:43.2+13 = 56.2us,1/56.2 = 17.79KHZ;

    Global mode(with Load4): 43.2/4 = 10.8us; 13+10.8us = 23.8us; 1/23.8 =42.01KHZ;
