passed through the liquid causes the crystals to align so that light cannot pass
through them. Each crystal, therefore, is like a shutter, either allowing light to
pass through or blocking the light.
LIF

to allow devices, such as the microprocessor chip, to be installed or removed with
minimal stress to the device.
