A method and system for establishing intensity levels for sub-pixels of a display device with overlapping logical pixels. The dithering system combines frame rate control techniques with contributions from overlapping pixels to establish the intensity level of each sub-pixel. The dithering system initially provides an assignment of frame numbers to each sub-pixel. The dithering system then receives a logical pixel color that includes an intensity value for each component color (e.g., red, green, and blue) for each logical pixel. The dithering system maps each component intensity value of each logical pixel to an intensity value with a low depth plus a remainder. The dithering system generates a sub-pixel intensity value for each sub-pixel of each logical pixel using frame rate control to adjust the intensity value of each sub-pixel based on the remainder and current frame number. The dithering system then calculates the intensity value for a sub-pixel by combining all the generated sub-pixel intensity values for that sub-pixel.
