Abstract

Abstract : We have developed a prototype of a head‐up display system using transmissive LCD with direct‐lit backlight type 2D local dimming and RGBW technology. We confirmed that the postcard effect, which is a phenomenon where the entire projection area including the noninformation area is slightly illuminated, was virtually eliminated. We also achieved higher white luminance and lower backlightpower.
