ABSTRACT:
A method for fabricating a pixel assembly on a faceplate of a display device, such as a field-emission display device. In one embodiment of the present invention, an application device is aligned over a pixel assembly on the faceplate. The present invention dispenses a specific amount of a substance into the pixel assembly such that the substance is dispensed primarily into the pixel assembly and such that the substance is not substantially dispensed outside of the pixel assembly. The present invention dispenses the substance into the pixel assembly such that the substance is not dispensed on a top surface of a matrix structure, where the matrix structure separates rows and columns of adjacent pixel assemblies. In one embodiment, the substance is dispensed into the pixel assembly from a printer head (e.g., an ink-jet printer head) adapted to dispense the substance. The substance is selected from a group consisting of: a color filter material, a phosphor material, a wetting material, a lacquer material, and a reflective layer material.
