Abstract
This invention provides equipment for fabricating partitioning ribs of a plasma display device. The equipment comprises a head, a driver, an X position sensor and a Y position sensor, a laser displacement sensor for detecting the distance of the head from a glass plate or substrate, a motor and a motor driver for moving the head relative to the glass plate, and a CPU for controlling various circuits. The head has nozzle members for ejecting partitioning rib grains by an electrostatic ejection method or ink jet technology to form partitioning ribs. The driver controls the volume of the partitioning rib grains ejected from the head. The X and Y position sensors detect the position of the head relative to the glass plate within a plane.
