ABSTRACT:
A data line drive circuit is equipped with a single line driver and a gate voltage generation circuit. The single line driver is constructed such that N groups (where N is an integer 2 or larger) of series connections of drive transistors and switching transistors are connected in parallel. The gate voltage generation circuit includes two transistors constituting a current mirror circuit, a drive transistor, and a constant voltage generation transistor. The range of an output current Ioutcan be controlled by changing any of the design values of the parameters including: relative values Kaand Kbof the gain coefficient for the transistors, the source voltage VDREF of the gate voltage generation circuit, and the gate signal VRIN of the drive transistor.
