| Abstract |
The experiments of three stages were performed to examine on the realization of Natural Colors of six color series(R, G, B, C, M, Y) and White color using R, G, B LEDs in this research. 1) When Natural Colors using R, G, B LEDs were realized with control software developed by manufacture in first stage, six color series had range of errors from 0.0499 to 0.1381. 2) When R, G, B of LEDs were mixed at the ratio (1:4.5907:0.0601) of Three Component Theory for realization of White in second stage, White was not realized to excitation purity. The second experiment was performed with corrected ratio (1:1.9960:0.2000). 3) Derived correction based on ratio of control steps of R, G, B LEDs was used for third stage. The six color series had range of errors from 0.0056 to 0.0140 in third experiment. Therefore, R, G, B LEDs’ system should be used with correction based on ratio of control steps developed by manufacture for color realization. |
