regulator ensures stable

operation even during battery

fluctuations.

Select from among 4 different

series to meet application

requirements for VF and IR.

Head-Up Display (HUD) systems in cars are normally mounted on or near the windshield to present useful information to

driver. This technology, first introduced in fighter planes, is getting adopted in the automotive industry for improving the

safety by enabling drivers to view relevant data, such as time, vehicle speed, and navigation information, without having to

take their eyes off the road. The block diagram below shows a sample HUD solution, in which the relevant information is

first processed and divided into RGB pixels, then displayed using LCOS (Liquid Crystal On Silicon).
