With the announcement of the completion of financing by Faraday future (FF), the long expected ff91 will finally usher in mass production. Recently, FF announced more details of its ff91 ultra luxury electric vehicle. The new car will use the industry’s largest head up display (HUD), which projects information 2.7 meters in front of the driver to help him focus on the road. < / P > < p > it is understood that almost all HUDs in the market use LCD display as PGU (picture generation unit), but the light that drivers can see through HUD is the same as that of ordinary polarized sunglasses. < / P > < p > for this reason, FF has developed a PGU based on DLP instead of LCD display. DLP technology does not use a polarizer structure as a light shutter, but uses a very small group of mirrors to guide the light in the PGU. Each small mirror acts as a pixel, while red, green, and blue LEDs are used as light sources. Millions of tiny mirrors in this microarray can output the required images through extremely small switching. < / P > < p > in addition, redundant core driving information is added to the HUD and instrument panel of ff91 to improve driving safety. Users can see speedometer and other core driving information on HUD and dashboard. < / P > < p > in addition to the head up display function, the ff91 is also equipped with a 15.4-inch display screen, which can be customized according to the navigation and frequently used destinations, and provides music and streaming media recommendations according to the preferences of car owners or users. < p > < p > recently, FF recently announced that it has obtained a debt financing loan of US $45 million (over RMB 300 million) provided by two major financial institutions in the United States. The loan will be used to support the final launch of its flagship electric vehicle ff91 project and to continue the development of ff81 for the mass market.
