Abstract:
A method to drive a display device with electron sources displaying grey scales divided into two families. The display device includes one or more rows and one or more columns. An intermediate potential lies between a first potential and a second potential. To display a grey level of the first family, the column voltage is pulse width modulated between the intermediate potential and the second potential right at the start of the row selection period. To display a grey level of the second family, the column voltage is pulse width modulated between the intermediate potential and the first potential from a determined instant of the row selection period.
