[0086] First, a first embodiment of a current generating circuit in a display device related to the present invention will be explained with reference to the drawings.
[0087] figure 1 is an outline block diagram showing a first embodiment of a current generating circuit in a display device related to the present invention.
[0088] Such as figure 1 As shown, the current generating circuit ILA related to this embodiment has a configuration formed of a signal latch section 10 (signal holding circuit) and a current generating section 20A. The signal latch section 10 includes latch circuits LC0, LC1, LC2, and LC3 (LC0-LC3), each of which receives a number for specifying a plurality of bits (a case of four bits is shown in this embodiment) for specifying a current value. Signals d0, d1, d2, and d3 (d0-d3) and holds them (latches one or more, as the case may be). The current generation section 20A outputs to the load current supply line CL connected to the load, which receives ...
