The Mathematical Model and the Creation Method of the Illuminations Module of Liquid Crystal Panels on the Basis of Colored Leds 000_5.pdf

The article considers construction of a module of illumination of liquid crystal panels on the basis of colored RGB LEDs. The algorithms of LED control for providing required illumination characteristics of liquid crystal modules are described. The algorithms’ adequacy was examined experimentally. The article also covers questions of influence of some characteristics of LEDs and constructive elements on illumination efficiency factor. The obtained mathematical models and algorithms allow to automate the development process of LED illuminations with forecasted characteristics. The ability to select elements with required constructive parameters for the specific LED illumination at the initial stage of development is appeared.
