Abstract
A method includes providing pulse width modulated signals. Each pulse width modulated signal is associated with a different bit, and the bits are arranged in an order to indicate an intensity of a pixel cell. Different frequencies are established for at least two of the pulse width modulated signals. Based on the logical states of the bits, the pulse width modulated signals are combined to form another signal, and the pixel cell is driven with this other signal.
