Abstract (en)
[origin: EP1324306A2] Voltages (Vcol, Vcol/2, Vss, Vrow+, Vrow-) are supplied as a function of data to be displayed. The circuit includes at least one voltage divider (12) and a voltage multiplier (11). The voltage divider produces a display supply voltage (Vdd). It further derives a voltage component which is supplied to a the voltage multiplier. The voltage component, and a voltage produced by the voltage multiplier are supplied to the display unit.
