LightTools Version 5.1 Enables Advanced Modeling of Flat Panel Display Backlights
November 2004 - LightTools Version 5.1 is the first illumination design and analysis program to enable easy and accurate modeling of sophisticated backlights for flat panel displays. This powerful software package can simulate the surface textures used for backlights, with built-in flexibility to vary the shape, size, and spacing of the texture elements. Complex texture configurations are made possible by mathematical methods, including Bezier and polynomial expressions, and also by the capability to import placement data created by external programs. These types of varied textured surfaces are commonly used in backlights for a number of flat panel applications, including televisions, computer monitors, cell phones, and automobile instrumentation.
LightTools 5.1 also adds significant functionality for stray light analysis through the use of enhanced filter capabilities. Added filters, enhanced Boolean operations, and the ability to group filters gives the user much greater flexibility in specifying which rays are collected and displayed. In addition, LightTools 5.1 includes the ability to specify surface zones that allow "active" areas to be interlaced to create two-dimensional patterns. This capability is particularly useful for the design of RGB displays.
LightTools 5.1 is scheduled to ship in January 2005. For more information, please send an email to info@opticalres.com.
