Method and apparatus for providing a pulse width modulation sequence in a liquid crystal display

A video projector apparatus, comprising:

• a data source;
• and
• a modified data word generator operative to convert data from said data source to into a modified data word;
• and wherein
• each of said modified data words has a plurality of thermometer data bits and also a plurality of binary data bits;
• and
• said plurality of thermometer data bits is included in each data word more than once.

A method for generating a modified data word comprising the steps of:

• providing a first group of data bits, said bits of said first group being of like significance with respect to each other;
• providing a second group of data bits, said bits of said second group differing in significance with respect to each other;
• and
• combining the first group of data bits and the second group of data bits to form the modified data word, wherein said second group of data bits is included once and further wherein said first group of data bits is included more than once.

A method for asserting voltages in a data storage device, comprising:

• converting binary data into a plurality of pulses;
• wherein at least some of said pulses are binary weighted pulses which correspond in value to a plurality of binary bits of the binary data;
• and
• at least some said pulses are thermometer pulses which have equally weighted values in relation to each other;
• and
• said thermometer pulses are each asserted more than once during a time period within which each of said binary weighted pulses are each asserted only once.
