Abstract

In one embodiment of the present invention, a liquid crystal display includes a liquid crystal cell having a liquid crystal material, and drive circuitry coupled to the liquid crystal cell to provide a low voltage signal to drive the liquid crystal cell. The low voltage signal may be a pulse width modulated signal, in one embodiment.

Claims (8)

1. A method comprising:

providing a pulse width modulated signal to a liquid crystal cell having a cell gap of from 0.5 to 1.5 microns; and

driving a data electrode of the liquid crystal cell without using a voltage greater than 3.3 volts.

2. An article comprising a machine-readable storage medium containing instructions that if executed enable a system to:

form a pulse width modulated signal;

provide the signal to a liquid crystal cell having a cell gap of from 0.5 to 1.5 microns; and

drive a data electrode of the liquid crystal cell without using a voltage greater than 3.3 volts.

3. The article of claim 2 , further comprising instructions that if executed enable the system to drive the liquid crystal cell with a pulse width modulated signal.
