The shutter consists of one red and one green polarizer/LCD combinations the size of the visible screen. | |||
The 5D10 in turn enables the red shutter, draws the red parts of display, turns on the green shutter in addition, draws | |||
the yellow (red+green) parts of the display, then turns off the red shutter, and draws the green parts of the display, | |||
at a rate of about 20 Hz. The slow multiplexing rate can lead to color artifacts becoming visible when the observer moves. | |||
In contrast with what is mentioned sometimes, the 5116 does '''not''' provide alphanumeric readout. The 5D10 takes care of this. | In contrast with what is mentioned sometimes, the 5116 does '''not''' provide alphanumeric readout. The 5D10 takes care of this. | ||
