Abstract: The present invention relates to a driving method for flat panel display devices, particularly a driving method combining a Multi Line Addressing (MLA) technique and a Frame Rate Control (FRC) technique, for flat panel display devices such as Liquid Crystal Display (LCD). In an embodiment the method of driving an image display device comprises the following steps: dividing row electrodes of an image device, having a plurality of row electrodes and a plurality of column electrodes, into a plurality of subgroups; selecting one of the plurality of said subgroups having a prefixed number of electrodes; performing a gray scale display by a frame rate control (FRC) by using a prefixed number of frames and a prefixed number of bits representing the gray levels; decomposing one of said frame in a number of time instants proportional to said prefixed number of electrodes; putting the bits representing the gray levels equally distributed in said prefixed number of frames.

Abstract: The device and method monitor the current delivered to a load through a power transistor including a sense transistor. The circuit includes a disturbances attenuating circuit that has a differential stage, and first, second and third stages referenced to ground, the respective input nodes of which are connected in common to an output node of the differential stage. The third stage is formed by a transistor identical to a transistor of the first stage and delivers a current signal through a current terminal thereof, proportional to the current being delivered to the load.
