摘要

如图所示的电压是执行器。当有n3个完全倾斜时,根据图1之间的关系,TFAMA模块由主动矩阵组成,其中施加图像信号,悬臂式压电驱动器和反射镜,为了使用TFAMA模块作为显示器件,倾斜角度的反射像元的变化需要表示为投影屏幕上点的光强变化。图2显示了TFAMA的光调制原理。倾斜的镜面像素,没有光通过光阑。当镜子像素点时,光线就会照到屏幕上。通过控制施加到相应执行器的镜像像素信号电压的倾斜角,可以在屏幕上产生最亮和最暗的256级灰度。

Micromachined Thin-Film Actuated Mirror Array For High-Brightness Projection Displays
As shown in voltages are the actuators. Ir of the individual corresponding When there is n3 are fully tilted, according to ths between the Fig. 1, a TFAMA module consists of the active matrix, where the image signal applied, the cantilever-type piezoelectric actuators, and the reflection mirrors, on top of order to use the TFAMA module as a display device, the variation of the tilting angle mirror pixel need to be expressed as the change in light intensity of the point on the projected screen. Figure 2 shows the light modulation principle of TFAMA. tilting of mirror pixels, no light goes out through the light stop. When the mirror pixels .‘ut1 light goes out to the screen. By controlling the tilting angle of the mirror pixel signal voltage applied to the corresponding actuator, 256 steps of gray levels in brightest and the darkest can be generated on the screen.
