DMD控制过程:

  1. 设置DMD Cell对应的CMOS为0/1,然后用MBRST来触发DMD Cell翻转,0对应-12C, 1对应12C。

  2. 怎么设置对应的CMOS(寻址方式

  3. MBRST控制(Block/行): Sel[1:0]选择Vbias, Voffset, Vreset电平。MBRST可以来自于DLPC,也可以来自于DLPA200 & DLPA300.
    VBIAS (19 to 28 V), VRESET(–19 to –28 V), and VOFFSET (4.5 to 10 V)

    在这里插入图片描述

micromirror reset signals (MBRST), -17.5V~21.5, revert micro mirror. Some DMD direct drive with digital signal with Voffset ,Vreset, Vbias voltage power DMD; Some DMD need use special DLPA200, 300 drive DMD.
? Control light source power in real time?
each micromirror to display four distinct pixels on the screen?
