Abstract
Provided is a jetting driver that can be used for various types of heads with minimal changes. The jetting driver includes: an image board receiving raw image data and generating image data by transforming the raw image data into a form suitable for a type of heads used; and an interface board physically separated from the image board, receiving the image data, and transmitting the image data to the heads through a plurality of channels.
Claims19
A jetting driver comprising:
- an image board receiving raw image data and generating image data by transforming the raw image data into a form suitable for a type of heads used;
- and
- an interface board physically separated from the image board, receiving the image data, and transmitting the image data to the heads through a plurality of channels.
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.
