Claim 10:
11. A substrate treatment apparatus comprising:
a pattern computer providing raw image data and setting data; and
a jetting driver controlling a plurality of heads based on the raw image data and the setting data,
wherein the jetting driver comprises an image board and an interface board physically separated from each other,
wherein the image board comprises an FPGA generating image data by transforming the raw image data into a form suitable for a type of the heads used,
wherein the interface board comprises:
a plurality of differential line transmitters for communicating with the heads;
an image controller receiving the image data and providing the image data to the differential line transmitters;
a heater controller providing a heater control signal for controlling a heater installed in each of the heads to the differential line transmitters; and
a voltage controller providing a voltage control signal for specifying a voltage level to be used by the heads to the differential line transmitters.
