Numerical simulation of LCDs

The first commercial software for numerical modeling of display systems with LCDs in 1, 2 and 3 dimensions is now being marketed.In case of interest ask for a free-of-charge evaluation version.

High-resolution BSDF/BRDF-measurement and evaluation finally made affordable ! 

At the SID 2004 conference in Seattle, a novel method for measuring the bidirectional scattering distribution function (BSDF) was presented, which is used for the ergonomic evaluation of displays. 

The method is based on the use of an imaging photometer to measure the lateral distribution of the reflected luminance and provides the Bidirectional Reflectance Distribution Function (BRDF) of the screen with high directional resolution in a limited area around the mirror direction.  

Since the method uses no moving mechanical parts, it is only slightly dependent on the geometrical parameters of the measurement setup. The introduction of the measuring instrument now makes the high-resolution measurement of the BRDF (BSDF) affordable for a wider range of users.

Controllable light source

This novel programmable light-source emulates a single line of a matrix-organized electronic visual display with an exactly controlled timing. It is designed for performance checking and calibration of measurement devices for motion-blur analysis and for research of perception of motion by the human visual system. The complete range of display screens from hold-type to impulse-type display can be emulated.
