Method for controlling an image display device

摘要

The present invention relates to a method for controlling an image display device and an image display device implementing this method. The invention relates more specifically to a display device having a matrix of cells, a column driver circuit and a column amplifier with resonant circuitry to recover energy. The invention proposes to optimize the method for controlling the column amplifier to reduce to zero the energy losses during the switching actions of the switches of the column driver circuit. To this end, the invention proposes to position the start of the period of oscillation of the resonant circuit in a manner dependent on the capacitance of the columns of cells connected to the resonant circuit via the column driver circuit such that the switching actions of the switches of the column driver circuit always take place when the voltage delivered by the column amplifier is zero.
