Patent ID: 8009126

Claim:
A current drive circuit comprising: a constant current source that generates a reference current; a current adjustment section that generates a first current at a first node, the first current being the reference current multiplied by a first coefficient adjusted according to a target grayscale; and a current output section including a plurality of transistors connected to the first node in parallel, and a control circuit that controls the transistors to be on or off, the current output section outputting a second current, which is the sum of the currents flowing through the transistors, the second current being the first current multiplied by a second coefficient according to the target grayscale, wherein a minimum value of the first coefficient is set in advance such that when the first coefficient is at the minimum value, the voltage at the first node is greater than or equal to a predetermined value set to be a value larger than the operation threshold voltage of the transistors in the current output section.
