ABSTRACT:
A device for generating levels of brilliance on a display screen. The device has a code-voltage converter, controlled by an asynchronous clock which makes a specific conversion of binary codes into discrete control voltages. These voltages are applied to the cells of the screen thus generating brilliance levels. The asynchronous clock is such that the control voltages generate levels of brilliance which evenly spaced over the luminance range.
