Development of Practical Heads-Up Display for Production Vehicle Application 890559

THIS PAPER presents an advanced heads-up display which has been newly developed for use in 88 Nissan Silvia model. The HUD consists of a projector with a newly developed high brightness VFD and light-selective film used as a combiner which is coated on the windshield. This combination provides good display legibility even under bright sunlight. The display shows the vehicle speed in a three-digit reading at distance of more than one meter from the driver's eyes. The windshield-coated combiner conforms to U.S. safety standards concerning light transmittance, abrasion and other performance requirements. Experimental data are also presented which substantiate the HUD's high legibility and confirm its effect in enhancing the driver's attention toward the road ahead
