Abstract

The problem encountered in addressing several liquid crystal-line displays is that of flickering. In most cases, this flickering is attributed to the relatively slow switch-on times required initially to change the state of the liquid crystalline material utilized in the display from its initial background state to its desired imaged state.

The problem encountered in addressing several liquid crystal-
line displays is that of flickering. In most cases, this
flickering is attributed to the relatively slow switch-on
times required initially to change the state of the liquid
crystalline material utilized in the display from its initial
background state to its desired imaged state.

The problem of flickering can be eliminated by initially
imagewise addressing the liquid crystalline display at a first
rate or switch-on time which affords electrical pulses of
sufficient duration to change the background state of the
liquid crystalline material to the desired image state. Once
the image is established, the image is maintained by scanning
at a second, faster rate, which is sufficient to maintain the
image state and eliminate flicker.
