<p>In a gamma correction circuit some bits of the digital data to be converted are used to select two gamma corrected "node" voltages. The other bits are used to make a linear interpolation between the two voltages using an addition circuit. In order to adapt the gamma correction circuit to a specific display panel, the set of "node" voltages can be programmed. <IMAGE></p>
