Fig. 3. Heat-generation characteristics of a color-conversion display with different NIR laser irradiation conditions. (a) Surface temperature of the display at different laser powers (20, 25, 31, 36, 39, and 56 mW). (b) RGB color expression of the display (R/G/B = 25/36/56 mW). (c) Infrared and visible images showing the surface temperature and color change of the TLC layer at different NIR laser powers.
