Luminescence characteristics of green phosphors with dwell times for fieldemission display design

Luminescence characteristics of green phosphors were investigated for diffe rent dwell times and anode biases for optimal designing of field emission d isplays. At a medium anode voltage of 2.5 kV, the brightness was decreased steeply with a lower dwell time (a higher device resolution). At higher ano de biases, however, the-brightness Was reduced slower than calculated from a given dwell time, Such a relationship between the brightness and the dwel l times seems to be explained by excitation profile of phosphor at differen t anode biases. For high-resolution field emission displays, it is consider ed that an engagement of higher anode biases is more beneficial to excellen t images in terms of brightness.
