| contents | Our group is developing a multi-user eye-tracked 3D display, an evolution of the single-user eye-tracked 3D display that we have already successfully developed. This display utilizes a slanted lenticular setup, where multiple perspective views are shown across the viewing field. Due to the constraints of the lenticular lens parameters, identical views are repeated across the field, limiting eye tracking to a single user. However, this limitation can be addressed using spatio-temporal multiplexing, where view zone groups are presented sequentially with a high frame rate liquid crystal display (LCD) and driver, in combination with a synchronized directional light emitting diode (LED) array. In this paper, we describe the operation and results of the backlight drive electronics, where a prototype using a white LED illumination matrix, a simplified LCD panel, and a linear Fresnel lens array serves as a test bed. |
