Patent ID: 7821480

Claim:
A charge transfer circuit of a liquid crystal display, comprising: at least one inductive element connectable between a first and a second common terminals respectively to a first and to a second group of lines of the display, said first and second terminals being connected to the respective junction points of switches connected, in pairs, in series between a third and a fourth terminals of application of high and low line supply voltages; and two switches respectively in parallel with a diode, these parallel associations being in series between said first and second terminals, each switch having a first conduction terminal connected to the inductive element and its control terminal connected to its second conduction terminal by a parallel association of a resistive element, of a capacitive element, and of a voltage-limiting element, the control terminal of each switch being further respectively connected to the midpoints of series associations of diodes connected between a fifth terminal of provision of a control current and said third terminal.
