Examples of graphics and visualizations from JVM Research

31x31 uniformity plot 31x31 point luminance plot.
A surface plot of 31 rows of luminance on a display where each row was measured in 31 points across.
For an 8bit/color display, there are 28 gray levels, or 255 (256 total levels, but the count starts at 0, not 1).
This bar plot is a visualization of data taken for inter-gray level or gray-to-gray response time, for 9 equally spaced gray levels, where each of the levels was a beginning or ending level for the measurements.
The levels are 0, 31, 63, 95, 127, 159, 191, 223, 255.

G-G Data Plot
Scrolling Box Visualization of a scrolling box on an LCD display, showing motion blur, and how a waveform which represents the magnitude of the luminance (from black to bright level) with respect to the spatial displacement on the display.
A plot of measured fall time / rise time for a falling and rising step response. The visualization shows the 100% point and the 0 point, and the 10% and 90% points — the points most commonly used as reference to determine the time of the step.
While this particular example was measured for a temporal luminance change on a display, it is similar to step responses that would also be measured for electrical signals.
Rise/Fall Diagram
3D Lenticular Lens drawing Drawing of a Lenticular Lens Array Autostereoscopic systems, partial view. The micro-lens system steers the light path to allow each eye to see different regions of the display behind the lenses. Developed for the 3D / Stereo display work of the IDMS.
