Spatially multiplexed pulse width modulation

A process of operating a pulse width modulated (PWM) display system, comprising:

• assigning a first time weight to a first display data bit of the PWM display system;
• assigning a second time weight to a second display data bit of the PWM display system, the second time weight having a weight value between 90 percent and 110 percent of the first time weight;
• determining a first threshold value for a first pixel of the PWM display system, the first threshold value being provided from a high spatial frequency threshold array;
• determining a second threshold value for a second pixel of the PWM display system, the second pixel being immediately adjacent to the first pixel, the second threshold value being provided from the threshold array;
• assigning a first display data codeword table index to the first pixel, the first display data codeword table index being a function of the first threshold value;
• assigning a second display data codeword table index to the second pixel, the second display data codeword table index having a different value from the first display data codeword table index, the second display data codeword table index being a function of the second threshold value;
• assigning a pixel intensity value to be displayed by the first pixel;
• assigning the pixel intensity value to be displayed by the second pixel;
• defining a first display data codeword for the first pixel as a function of the first display data codeword table index and the pixel intensity value, and
• defining a second display data codeword for the second pixel as a function of the second display data codeword table index and the pixel intensity value, so that:
• a value of the first display data bit defined for the first pixel is different from a value of the second display data bit defined for the first pixel;
• the value of the first display data bit defined for the first pixel is different from a value of the first display data bit defined for the second pixel;
• and
• the value of the second display data bit defined for the first pixel is different from a value of the second display data bit defined for the second pixel.
