Fig. 4. Repeated RGB color generation by the light-irradiation-based color-conversion display. The on/off time for all the displays was fixed at 30/30 s. Repeated driving characteristics of the (a and b) red (laser power: 25 mW), (c and d) green (laser power: 36 mW), and (e and f) blue (laser power: 56 mW) displays. (g) Optical microscope image of the TLC capsule after 30 cycles of repeated heating/cooling (5/5 min) testing.
