抜粋

A new paste and fabrication procedure for forming stable fluorescent layers on flat panel displays formation is discussed. We have characterized the uniformity and thickness of the fluorescent paste and, using simulations, have found that the optimum fabrication conditions are with a paste sectional area of 2050 µm<sup>2</sup>, a dispenser pressure of 0.5 MPa, a nozzle gap of 30 µm, and nozzle inner diameter of 0.14 mm. In addition, a contact angle of 0° is the optimum surface of the glass substrate, supporting a heat-treated black matrix. The finished layer has a uniform thickness of 13.9 ± 1.1 µm, and a thickness/width aspect ratio of 0.1. The new method can form uniform 8 ± 1.5-µm-thick fluorescent layers at each opening in the black matrix; it reduces contamination, and can be extended to large substrates.
