ECB mode.
Director profile information for each voltage condition applied to the liquid crystal layer calculated through the LC simulator is provided in a separate Excel file. The axis notation for LC director angle, phi, and theta angle conditions in Excel is as shown below. In Excel, the z-axis information can be assumed to be the relative depth position used in simulation.
Assuming ne = 1.7 and no = 1.55 for liquid crystal. Material dispersion of the liquid crystal itself is ignored. Assuming 440nm for blue, 550nm for green, and 650nm for red.
(1) Calculate and present the LC cell gap conditions to implement the optimal normally bright ECB mode for green light.
(2) Calculate what the transmittance levels will be at 0V for each R/G/B in the normally bright ECB mode LC cell designed in problem (1) and compare them by wavelength.
(3) In the normally bright ECB mode LC cell designed in problem (1), voltage (x-axis)-transmittance as the voltage applied to the green light increases, using the conditions presented in the problem and the information in Excel. (y-axis) Draw the curve. (You can use any SW tool you can use. MATLAB is recommended)
(4) In problem (3), the second polarizer was removed. Calculate and plot the Stokes Parameter values (S1, S2, S3) according to the applied voltage. In other words, just plot V (x-axis)-S1 (y-axis), V-S2, and V-S3 respectively. (You can use any SW tool you can use. MATLAB is recommended)
