提出了多色荧光液晶显示器（LCD）。含有二向色性荧光染料的扭曲的双折射（TN）池被用作UV快门、偏振开关和有源发射器。我们描述了两种荧光液晶显示模式的不同堆叠顺序的荧光TN盒，交替荧光层和偏光片。通过在TN池两端施加电压，可以连续地改变荧光颜色，并且在两种模式下都证明了绿色和蓝色、红色和绿色以及红色和蓝色之间的颜色变化。通过将液晶盒的偏振光发射现象应用于荧光LCD，使非偏振激发UV光的使用成为可能，亮度得到显著改善。
Multicolor fluorescent liquid crystal displays (LCDs) are proposed. The twisted nematic (TN) cell containing a dichroic fluorescent dye is utilized as a UV shutter, a polarization switch and an active emitter. We describe two fluorescent LCD modes of different stacking order of the fluorescent TN cell, alternative fluorescent layer and a sheet polarizer. The fluorescence color can continuously be changed by applying a voltage across the TN cell and color variations between green and blue, red and green, and red and blue are demonstrated in both modes. The brightness is considerably improved by applying the polarized light emitting phenomenon from the LC cell to the fluorescent LCD, which makes the use of nonpolarized excitation UV light possible.
