Once you have these you can drive the display as you want.

If you apply DC (for longer than the brief instance you mention), you end up destroying the LCD (well, that segment). PWM'ing the signal won't be enough, either (as that only fluctuates between 0-5 volts DC); what you would need to do (minimum) would be to bias the signal in the negative direction by 2.5 volts to get it to fluctuate between -2.5 and 2.5 volts; depending on the display, this may or may not be enough to drive the segments (and thus an amplification stage would be needed).
