Abstract:
The method of problem decision of light output from LC display backlight, working with one LED in approximation of thin waveguide is considered. Attention to two methods of calculation, with piecewise continuous density of micro structure arrangement and separate calculated position of each micro structure was paid. Calculation results were modeled by Monte-Karlo method of ray tracing.

Key words:
waveguide, backlight system, display.
