In a Car driving, it is known to be dangerous for the driver to read heads down display panels. In a PC-car or Networking Car, it is impossible for the driver to look down on the computer screen and read text web browser while he is driving on a high intensity road. In the "Car Heads Up Display" invention, Web browser are projected onto the windshield with co-polarized lens that is fixed on the roof inside a car. The beam of co-polarized light reveals a co-polarized image on the windshield. The driver wear a pair of co-polarized glass. The direction of polarized light of the two lens are perpendicular to each other. The polarized direction of light that is projected onto the windshield is parallel to the right lens. As a result, the picture that is projected onto the windshield is visible only to the right eye while be invisible to the left eye. Function of the left eye is to see the road condition only, the right eye is to see both the road condition and the image that is projected on the windshield. With this task allocation between the two eyes by co-polarized beam of light, I reached two features: 1. Keep the valuable windshield totally transparent which is very important for the driver to drive safely. 2. No matter how complex the two dimentional co-polarized picture that is projected onto the windshield is, the driver won't feel hard to see the road condition. Challenge: A totally transparent windshield is valuable for driving safely, a Heads Up Display which enables both totally transparent windshield and images for the driver to check vehicular functions and browse Internet.
