ABSTRACT:
A display device, such as an electroluminescent display device, includes a matrix of pixels, each pixel being driven by a drive pulse that is pulse width modulated. The width of the drive pulse is controlled by a gamma correction device, in which gamma correction information is supplied in the form of a separate pulse distribution-modulated signal.
