Patent ID: 7408542

Claim:
A method of addressing a display panel comprising the steps of: providing a driver for selectably addressing individual cells of said display panel by applying voltage across corresponding terminals of columns and rows of said panel; applying, for a first phase of duration T 1 , a first DC voltage across the terminals of a solenoid, so that the latter stores current in the form of magnetic energy; selectably addressing at least one individual cell of said display panel; discharging, during a second phase of duration T 2 , at least some of the energy stored in said solenoid into said column(s) or row(s) selected by said driver until the voltage across the terminals of said row(s) or column(s) becomes zero; maintaining, during a third phase of duration T 3 , a zero voltage across the terminals of said column(s) or row(s) selected by said driver and optionally modifying said selection of the column(s) or row(s) during this phase; charging, during a fourth phase of duration T 4 , the solenoid with the current stored in the form of capacitive energy into the capacitance formed between said column(s) or row(s) selected by said driver until the voltage across the terminals of said column(s) or row(s) reaches a given amplitude; and maintaining, during a fifth phase of duration T 5 , the given voltage amplitude across the terminals of said capacitance formed between said column(s) or row(s) selected by said driver so as to create a write current in cells of the display panel.
